Hi !! Since two days my windows-7 laptop is not connecting to the internet. When i tried to troubleshoot the issue i got a warning that DNS server is not responding. But the internet connection exists. As data transfer rate is changing and also the torrentz is running. Only problem is for the web pages...I alos tried restoring the computer to all the previous dates but still problem exits. Can somebody help me... Thank you..

Hi, This issue can occur by incorrect DNS settings. I suggest you perform the following steps to troubleshoot the issue. 1. Click "Start", input "NCPA.CPL" (without quotation marks) and press Enter. 2. Right click on the connection that you use for the local connection, and then click "Properties". 3. Click to select "Internet Protocol Version 4 (TCP/IPv4)", and then click "Properties". 4. In the Internet Protocol window, let's change the "Preferred DNS server" to 208.67.222.222 5. Click 'OK' twice to complete the modification. If the issue persists, please repeat the steps and change the "Preferred DNS server" to 208.67.220.220. Meanwhile, I would appreciate your help in clarifying that if the network is based on a router or a DSL modem. If there is a router, please bypass it and connect to DSL modem directly for a test. Thanks, Novak

Just had this same problem. Installed Win7 Pro 64-Bit on December 16th. Hasn't activated yet (our admin is still sorting out the KMS server). Yesterday afternoon, my home wireless connection lost access to the Internet. Access to the LAN is fine. Finally determined that it's not resolving DNS. Funny thing is, even NSLookup wouldn't resolve anything, yet, the DNS servers were fine. Kept noticing two wireless connectoids in my network settings. "Wireless Network Connection" is my normal wireless connectoid and was connecting fine. The second was "Microsoft Virtual WiFi Miniport Adapter" and was showing disconnected (as I expected). But, I couldn't figure out where that second connectoid came from, so finally, I disabled it. As soon as I did, my DNS sprang to life! I'm not sure if the OS is trying to activate, and interferring, or if that connectoid appeared as part of a Windows update, but disabling it fixed it for me instantly.

I am having the same problem after I upgraded my Gateway desktop from Vista to Windows 7. My Win 7 computer is on a wired network and I was able to browse the net for a few mnts after the upgrade but started getting DNS Server issues. There doesn't seem to be any issue with the DNS server since other computers on the same network are able to access the internet. I have VZ FIOS coming in and I have DLINK DIR 655 router. A computer directly attached to DIR655 is able to access the internet. My windows 7 PC is attached to DI 604 switch (using the router as a switch). Nothing changed in network and it worked just fine with Vista. Only change is upgrade from Vista to Windows 7. I tried configuring the DNS server to 208.67.222.222 but that didn't help either. I appreciate any help.

Just to add a bit more details to my previous post, I verified network by attaching another XP laptop to the same switch and it works just fine. I am able to browse the net. There is no issue with the DNS server configured in the router or in network but Windows 7 isn't happy. Any help is appreciated.

I reinstalled Windows 7 and still intermittent internet connection issue remains. I called Gateway and they advised me to restore system to factory setting which is Win Vista. I asked them for the Win 7 network driver and they don't have any support for it (although they did provide upgrade DVD for it). It seems like Win 7 64 bit doesn't have a good network driver for Intel network adapter that is in gateway SX2800. I was hoping with Win 7 Microsoft would have better drivers but alas. Would anyone from Microsoft want to help (or I will have to load Linux on it)?

Hi, I just switched on my laptop. I have wireless router through which I access my PC and laptop. I too have the same problem Purchased just one month ago. Really dont know what to do. Any help. Regards skrcmr

Do you have your DNS server on your LAN subnet, or is it performing a DNS query to an outside public IP?Of course, I have to ask do you have any other AntiVirus/Firewall running then Windows Firewall? In either case, have you tried to disable the firewall to see how it reacts?

Since it was working intermittently it can't be firewall issue. It can't be an issue with the DNS server since all other computers attached to same router are working just fine. To me it seems like a network driver issue and Gateway didn't provide me any driver except the one that is shipped within Win 7. I even tried the driver that I downloaded from Intel site but same behavior continued. Unfortunately I couldn't wait for Microsoft/Intel/Gateway to fix it and have moved back to factory installed Windows Vista and not encountering any issues at all. I am not happy about using the legacy OS but don't have time to debug things.

Do you have any VPN software installed on either system? I ran into a problem when I upgraded over Vista x64 to Win7 x64. 1 - I had to uninstall the VPN software and reboot the box. 2 - I had to open Device Manager, Choose View - Show Hidden Devices 3 - Delete any and all Intel networking components (actually you choose uninstall)4 - Delete the Microsoft 6to4 Adapter (it will be remade on the reboot)5 - Delete all the Microsoft ISATAP drivers.Reboot, and let the OS detect and remake the network adapters, 6to4, and ISATAP drivers. Install the network adapter...That's what I had to do to make the DNS not be so flakey. Also, instead of visiting the OEM site, I visited the Intel website and downloaded the latest driver from there. Worked like a charm.David Dracoules

Thanks for sharing your fix. I am sure it is going to come handy for many others. I will try it one of these days when I am feeling like upgrading again :)

In (TCP/IPv4) Properties, please also select the "Validates settings upon exit" check box and exit to check the result.

Ok, so i just tried the solution provided by Novak but didn't get very far with it. So I played around a little more. Tried using a wireless XP laptop to download a network driver for my MSI K9A2 Platinum mobo, installed the driver from a flashdrive but still nothing. so for some reason i just rolled back the driver. then just click update driver and now my connection is working. I dont get it, but if this helps anyone then this post will not be for nothing. gl all

Disabling "Microsoft Virtual WiFi Miniport Adapter" resolved my issue as well. Before disabling it, the wired connection worked properly but wireless would not resolve DNS, even when using NSLOOKUP. I could ping the Internet and browse by IP address so it was definitely DNS not working. Setting static DNS servers did not help.Victor S. - Enterprise Integration Solutions, RCM Technologies

HELP!!! I just got this Gateway yesterday & Have no problem connecting hard wire, but when trying to connect to any wireless connection get the same error. My husband was the technical one, but we are now separated & I HAVE NO IDEA what I am doing. I contacted Gateway & they emailed me an atheros driver or something, but it did absolutely NOTHING. I am lost. The whole point of having the laptop was so I can be on the go with internet access. Now I don't know that the heck to do??!?!?!Any help would be totally appreciated.

This one worked for me! I have been trying to find the answer for two days straight! Thanks for the help!

I too was able to connect to network (torrentz) but could not use internet. So i went to -change adapter settings -> right clic on wireless network connection --> configure-> advanced-> 802.11b preamble --> long only ok i also disabled microsoft miniport adapter wich by the way is hidden u have to "show hidden things" option. and it start to work i really don't know why it just did

I had the same problem on my new DELL xt2 WITH Win7 x64. JCrissup's suggestion to disable the "Microsoft Virtual WiFi Miniport Adapter" worked like a charm. The Wifi connection instantly came alive. Many many thanks...saved me hours of agony reloading drivers etc.

Wow. Thank you SO much. I had the same problem: Win 7 - 64 bit (new Dell Latitude E6400 laptop) with all the factory configurations. I could connect to the router, see devices on the LAN, and ping sites on the Internet via IP address, but DNS never resolved. Disabling the MS Virtual WiFI Miniport Adapter worked! Thank you, Thank you.

Hi; I have an Acer One D250 netbook with Windows 7 Starter, which seemed to be able to connect wireless to anything and everything since I took it out of the box. However, sometime around the 20th or 21st of April, it suddenly lost that capability. The computer indicated that the problem was with the DNS. I have tried all of the remedies on this webpage, with no luck. Yes, I have changed the DNS numbers, reloaded and updated drivers, restored, disabled this and that, and nothing seems to work. It connects instantly to DSL. I have gone to a different location and connected via DSL...no problem. At the same time, I have gone to several other locations in this area where wireless service was available and I get the sameresults...no DNS. I have an old Dell laptop with XP and it is able to connect wirelessly, not just from my home, but from the other locations I took the Acer as well. All the routers are not bad, especially if other OS are able to connect to them...it is something to do with Windows7, I am convinced of that. I am wondering if being unable to connect wireless was a result of some glitch in a recent update? I get updates automatically; the Windows7 seems to be updating this or that almost everyday, whereas auto updates on my old Dell are disabled. There has to be something which occurred in the last week that would all of a sudden cause Windows7 to lose its wireless capabilities. Regardless, I use this Acer on almost a daily basis and I need to find out how to get it to be able to connect wireless again.

Disabling the Microsoft Virtual WiFi Miniport Adapter resolve the issue right away.

Hi Yes, I tried disabling the Microsoft Virtual WiFi Miniport Adapter, with no luck. Several times. This, besides confuguring DNS server and the whole kit and kaboodle. Nothing. As I say, connects fine via DSL, but on wireless...not! I beginning to get rather dismayed, as I bypassed some good buys on new units with Vista to buy the netbook with Windows7, mainly because the salesperson advised me that there was "no comparison" in regards to the Windows7's connection abilities. Meanwhile, a friend at work has a laptop with Vista and he has no troubles whatsoever. This just isn't right!

Hi, I had the same problem since I started my LapTop this morning. After searching myself, I found no solution. Davids uninstall everything and let the system reinstalling the network drivers and deleting all entries(related to my laptop) in my router provide me to reconnect to my Wireless Lan router and to the internet. Thanks lomeco

Novak, I have been having intermittent problems with DNS not responding. I tried your two DNS address solutions above, one worked for a day but then it goes out again and then I have to reset it. I have spent hours on the phone with tech support to no avail. For instance, this morning it was not responding after working all night last night. I reset to the DNS address above which seems to work the best "208.67.220.220" but then my boyfriend couldn't log on as it said their was an IP address conflict. So I reset the DNS to obtain automatically and it seems to be working fine. I have no problems with service anywhere but at my house where we just switched to AT&T DSL. It hasn't worked right since on my computer but my boyfriend's computer works perfectly fine. I am running Windows 7, he is on an older operating system. Any help would be greatly appreciated. I have tried numerous other things with tech support (too many to list) including disabling the firewall, clearing out the DNS and starting over, etc.

try uninstalling norton antivirus, that can block your firewall too.

I've been beating my head against this for days. Disabling the Virtual WiFi Miniport Adapter worked perfectly for me as well. Thanks!

I'm an idiot on computers but am havingthe same problem please can someone tell me how I disconnect from the wifi adapter thing please?!

I don't have the WiFi Miniport Adapter so that can't be the issue...

I had the same problem, Thanks to you Novak, it worked with the second DNS setting

I too am experiencing a very similar problem: I use a 2Wire DSL Router to connect one or two wireless computers and four or five wired Ethernet computers. The configuration worked fine with Windows 2000, which was upgraded to XP on the wireless machine while all wired machines ran Vista (64 Ultimate). Everything worked fine. I upgraded all Vista machines to Windows 7 Ultimate as well as the wireless machines. The Wired Ethernet machines see and connect to the Wireless machines fine. The Wireless Windows 7 machines connect as well as before to the Internet. But the Wireless machine, while it see's the other machines in the Workgroup, using whatever interface, Windows Explorer or the Network Connections interface, doesn't connect to the wired machines in the workgroup. All the machines have at least one account in common, using the same password. The wireless machine connects to the Router. When, through the network server on the 2Wire router, the wired machines are queried about sharable files, the same name resolution error appears. I have half-duplex file sharing, which I might be tempted to live with except that backup requires a 'push' connection. I have disabled IP-V6. The fact that I can resolve names through the routers 802.11G connection from the wired connections but not the other way confirms the physical link. I did try assigning the preferred DNS server as recommended. This is a NAT configuration using DHCP. The router, which certainly resolves the names of all the clients in the workgroup, generates a message "Cannot find 'file://192.168.xxx.xxx'. Make sure the path or Internet address is correct." An attempt to open nodes from the wireless node generates a \\computername is not accessible. You might not permission... The specified network provider name is invalid. This does appear to be DNS related. Nothing changed other the Windows 7 replacing Vista 64 Ultimate and XP on the machines connected through the router's internal 802.11G facility. The router was unchanged. This router, while it is in millions of homes using the ATT DSL services, is not on the list of DSL routers approved by Microsoft. But a change in Windows 7 requiring ATT customers to buy a new router and take on its support seems unlikely to be a marketing campaign. One message suggests that the wireless client machine is looking at the DHCP router as a server, but should have been fixed by assigning DNS resolution as suggested here.

Hey buddy thankz 4 ur kindly info. i just follow the step of yours , now it works properly once again thankx a lot now m safe wid this ____ DNS pro hahahhahahha NOVAK Wu i have one lovely and sweet kiss 4 u ...

I've tried changing the dns address. I've tried reinstalling the wireless network card and I've tried disabling the virtual wifi miniport adapter and it's still having problems resolving dns on win 7 64 bit. Any other ideas? thx in advance

Hi I have a Sony VPC-CW17FX laptop. It has Windows 7 on it. About a week ago we did a system restore (without disks) and now I am experiencing the DNS server not responding issue. I was able to connect to the internet and download Norton and then the next morning - no internet - this is when I started getting the DNS error. I have tried the above resolutions but its not working. I have no system disks as I bought the computer used. Any ideas?

Hello I had the same problem by incorrect DNS settings. I applied your response above and it works! thanks Novak

thanks this worked for me :-)

I had the same peoblem. After carrying out your suggestion, all now works well. thanks a million.

I have a dell vostro with windows 7 pro. How do I disable 'Microsoft Virtual WiFi Miniport Adapter'? Please help me. I am having trouble finding this.

Ok Im weirded out I have always had those error messages now they just got worse so i did what you said and that stopped most now the dns is trying to talk to my Buffalo Network drives........ and its getting mad because they dont talk back. Sorry I have to make light of my sitution. and when I read my logs for windows 7 they are saying its all my routers fault. and my routers log isnt saying anything. and everything appear to be right. and it seems to be caching aloting

I'm Having a similar problem I can hook up to the internet wired through the modem but whn I hook up to router it say ihave a connection but when i do the network troubleshoot it comes up DNS SERVER NOT RESPONDING i don't know what else to try i disable the Microsoft Virtual WiFi Miniport Adapter, and tried changing dns number but it won't connect through the router and this is a new modem i also configered everything.

I'm also suffering with the same problem. I have Windows 7 Home premium and have a HP Pavilion dv4-2155dx. One night it was working I shut it down and windows did some automatic updates next morning it would not open any web pages and will say windows can't communicate with device or resource (primary DNS server) also Security or Firewall settings might be blocking the connection. I was on the phone for hours with Sprint my wireless provider and HP tech support and all of their help could not solve problem and then I discovered this forum and realized this is not a unique problem but a common issue with varios computer models and Internet providers. Seems like windows 7 seems to be have a common link. I restored computer and tried novak suggestios but to no avail. Has anyone found another solution to this baffling problem??????

FTW... For the last 5 hours I have struggled with this issue. Both at work & at home...no wifi connection, just the stupid useless DNS server isn't responding message. Thanks JCrissup for the simplest and yet most effective solution to this problem. Come on Microsoft, why give us a wireless adaptor that can't connect to anything and even worse, causes headaches & heartaches for half a day.

My problem exactly on the same setup, W7-64 laptop with the MS Virtual WiFi Miniport... disabled it and all is working again, thanks!

I had the same "DNS server not responding" issue that most everyone here has, and I found a simple solution that worked for me. TRY THIS Go into "Device Manager", and find your "network adapters" Disable your network adapters and then enable them again. (effectively resetting them) I just went ahead and reset both of them (my Broadcom WLAN & my Realtec PCIe Family Controller) Internet works just fine now.

Hi, Just want to add I have exactly the same issue. What's up? Thanks

Thank God for you I disabled mini and is working alot better now thanks for the info. tobiaslu

Hi Novak, It worked for me. Its a great help. I have bee struggling a lot to clear this error for quiet a long time. Yhanks again, Nirmal

Hi Novak, the first one didn't work, but 208.67.220.220 worked great. THANKS! However, I remember reading a previous post from someone who said your solution only worked intermittently. Well, since I checked out this forum only today, I guess time will tell. One other thing I wanted to ask was, on your 12/24/09 post, you advised us to check the "Validate Settings Upon Exit" box after entering the new DNS. I have not done that, since I saw that post after your initial post that told us how to resolve the problem. I am, BY NO MEANS, a tech guy, so I apologize for my ignorance and/or stupid question. But, what is the difference between checking that box/not checking that box?? If Novak's not around, can someone please assist me with my question? Should I check that box or not? Thanks to everyone... Hope to here from someone soon:)

Hi Novak and anyone else who may be able to help: Am using W7 64, I am constantly getting “DNS server not responding" when on WIFI but able to get a stable cabled connection. Have tried two different WIFI routers, switching the cable between the modem and the routers, and so believe it is not the hardware causing this problem. Moreover, this is a sudden change as previously did not have any problems. I have tried Novak’s suggestion of changing the DNS server to 208.67.222.222 and 220 but it doesn’t help. What is interesting is when clicking “additional troubleshooting options” the problem resolves itself but only temporarily. Have tried all other solutions suggested so far on this thread to no avail.

THANKS NOVAK! YOUR A LIFE SAVER!

IT DIDNT WORK ____!

I am having the same DNS Server not responding when using Windows 7. I also have a lap top running on Windows XP and I am experiencing the same problem. This has happened before in the past few days but the next day both computers were able to make connection. I think it may be something to do with a technical problem that is being experienced by the server that I am attempting to connect with.

This happened to me soon after installing Norton 360. IP address seemed correct, disabled the mini as suggested, that didn't help. I started to suspect Norton after reading minisizekev above. I did not want to uninstall Norton so finally I reset my firewall settings using the "restore defaults" option under Windows Firewall and viola! Back up on the Net. Will see how long the connection lasts . . . Control panel --> System and Security --> Windows Firewall --> Restore defaults

Had this problem weeks ago until stumbled upon this thread. Works like a charm. Can I get the link to any thread that teaches me how to manually troubleshoot internet connectivity problems?

troubleshooting depends on the method you use to get online. google is your friend http://lmgtfy.com/?q=how+to+troubleshoot+internet+connection

Try this....check your router settings...."Uncheck" Enable MAC Address Filtering in Firewall tab

BEST SOLUTION : try to contact your ISP provider and ask him for DNS address

I had the very same issue. Do as Novak suggests and click "start" then type in 'ncpa.cpl'. Follow instructions as below to Internet protocol 4 and select 'properties'. You'll notice it may say "use dsl address" or similar - it may be 192.186.1.1 or 192.168.0.1 Type either of these into Explorer and which ever takes you to the router settings page is the number that should be present in here. Failing this you can try selecting - "assign dsl automatically" - both of these worked for me after trying everything. this pure guess work did the trick.

hai thank u very much , ,y problem has been resolved....................

Just had this problem out of the blue yesterday. What seemed strange was that while I could not get on the Internet and all open browsers closed on me, I was at the time listening to radio on the net and that was unaffected. I shut down and hoped it would "heal itself" overnight. It didn't. And a couple rebotts didn't help either. I called my service provider and was told to powercycle my modem. Worked like a charm!

It worked for me thanks!

Worked perfectly, Novak. Thanks

Hi there, I have the same DNS server not responding problem in my LAN, Win 7 64. When I try to change the DNS address as Novak suggested, it gives me a warning: Multiple default gateways are intended to provide redundancy to a single network. They will not function properly when the gateways are on two separate,disjoint networks (such as one on your intranet and one on the Internet) Do you want to save this configuration? The IP address: 192. 168. 1. 123 So what shall I do, PLZ help!

Hi all, I had the same problem, so changed the Preferred DNS server as Novak proposed, which worked, with the first ip address: 208.67.222.222 This got the connection back, and I then deleted the number, re-ticking the Auto Detect box, and my connection remained good I'll definitely come back here for future Win 7 advice - Many thanks all

THANKS SO MUCH!!!!! I just spent 1 hour online lookin for an answer to this DNS question. I tried three different forums before I found your response. This was absolutely a life saver and thanks for putting it in plain english for the non-techies in this world. mzRED

Thank you soooo much!!! This is amazing. I have finally got my problem solved!!

208.67.220.220 doesn't work and yes I tried all the other remedies that are stated above I even reinstalled my Windows 7 Pro several times and got same problem (so the issues are there under a new install), nothing simply works and Microsoft seems not to be addressing the issue. I rely on my computer for business and school so I had no choice but to go back to XP (which cost me a whole day of downloading), is there anyway to get my money back for the Windows 7 Professional I purchased? Note: No problems whats so ever with the connection with the XP on my machine.

amazing... worked on first try! thank you!!!

I have the same problem but i go into device manager > view show hidden devices > network adapters and "microsoft virtual wifi miniport adapter" isn't there. Why is this ?!

Even I face the same problem. With me the problem is intermittent and that can not be predicted. All of a sudden my internet stops working. I use a router. However other machines connected the same router continue to work. Can any one help? Laxmikanth

thanks so much for the help this seems to have solved my problem allthough it was working yesterday then stopped working this morning but as soon as i changed the preferred dns and alternate dns everything is working great

Novak, I've attempted your solution, with no success. As far as I can tell, the "Microsoft Virtual WiFi Miniport Adapter" is not present in my system, so I have not been able to make use of that suggestion. I am becoming almost frustrated enough to cry over this, because this is pretty much a waste of a computer until it can connect most of the time. PLEASE HELP. I am, very rarely, able to get my new Windows 7 Gateway DX4300-15e PC to connect to to the internet through my wireless network, but it normally will connect to the network and fail to connect to the internet. Several PCs and other devices, wired and wireless, connect to the same network flawlessly (including my laptop, upgraded from Windows XP Pro to Windows 7). The router is a D-Link DIR-825 (operating in 2.4GHz mode), connecting to a Time Warner cable modem.

resetting my windows firewall policies to default worked for me

This issue is driving me nuts :-( I just got a 3G Router (Planet WNRT-625G) using a USB Modem to connect a couple of PCs thru a LAN connection. My machine is a Dell Vostro running W7 32 bits. At first it seemed to work fine but I started to get that error. Basically I have got 5 minutes of connection and then it goes off and eventually I have to plug the USB modem right into my box. I tried the 208.67.222.222 thing but it didn't work. I haven't looked at thte Miniport thing yet. Just to clarify that issue, when the system says that the "DNS Server is not responding" which DNS Server is it ? Should I have one ? My ISP's ? When changing the 208.67 I did it on my Network Connection but what about the DNS settings on the router ?

The problem was with my USB Modem, I had a new one which didn't seem to work a Huawei E1756C I guess a compatbility isssue. I changed it back to the old one, a Vodaphone K3760, and its working like a charm.

oh thanx bundle of thanx u have decrease my tension ,, that realy worked

____ yeah novak you the man!!

I am also experiencing this problem. Periodically I am unable to connect to the internet and every time when I click to diagnose it comes up that my dns server was not responding. This is very strange behavior because I can occasionally close the troubleshooter and it will work for a brief amount of time. But inevitably this issue comes back. I have followed the above steps outlined by Novak by setting my preferred dns server to 208.67.222.222, and I have also attempted to power cycle my cable modem, all to no end. I still get the same issue. What other steps can I follow to try and address this? Is there some configuration on my router that I need to play with? Do I need to contact my ISP and if so what specifically do I need to tell/ask them? Should I just downgrade to Vista (seriously not the preferred solution)? Thanks, N

We too have the same issue, seems Microsoft is not interested in giving a solution to this one! Even though a lot of people seems to be affected by this. Vista was one crappy OS, Win7, after the initial bursts seems to be more Crappier!!! Most of our users have moved to XP. We have been testing/using Windows 7 for over a year now and sill there no solutions for the network problems.. ... how long can anyone wait?

A temperory workaround, until MS comes with a solution which solves everyone's problem, is, if DHCP is been enabled then go to the wireless adpater properties and set DNS to manual and enter 8.8.8.8 or 208.67.220.220. Give OK and OK. Now connection will get established. But this is not stable and will go back to disconnected state after some time, inour case some 3 to 4 hours. We reverse the process and we get connecteed again. We have 3 Windows 7 and 2 Windows XP laptops connected to our Wireless router one Win7 laptop has this issue, we recently reinstalled the laptop and did a windows update also, but still issue is there, it just started some 2 weeks ago, might have been caused by automatic updates. Who knows? Hope MS comes out with a solution soon, from all the forums it is pretty obvious that most Win7 users are affected.

I disable my "Vmware virtual ethernet adapter for Vmnet1" and everything is now OK. the DNS problem seems to be a conflict with other netwrok driver. I also have a third party vpn drive but not problem with it. it is a brand new laptop with win7 32 bits. I have another older (6 months old) laptop connected on same wireless router without any problem.

I had the same problems with a Linksys WRT54G...After days and trying these things listed here, I finally stumbled upon the solution...Under my router's page I went to basic set-up and clone MAC address, I enabled it and then saved the settings....Voila it was fixed...Go figure...For the record I still have mini wifi adapter enabled, I disabled it and it has no effect. and all the other stuff Suggested had no effect either...I have windows 7 and Cable ISP..

I replied in the wrong spot...I just went to the router's home page (Linksys WRT54G) and under basic set-up and then Clone MAC address---Enable----Save settings.....It worked ..

thanks boss this works 4 me thank u so much

Hi, I have a DNS problem. I have done everything in this forum. It works at home when it is connecting to one internet provider(eircom) and it works anywhere else that uses the same provider. But when I am in my college home it will not connect, because we are using 'UPC' - a different provider. It seems that the laptop is 'locked' into using only one DNS server, does anyone know how I can fix this?? Any help at all would be great. Thanks

Just had this same problem. Installed Win7 Pro 64-Bit on December 16th. Hasn't activated yet (our admin is still sorting out the KMS server). Yesterday afternoon, my home wireless connection lost access to the Internet. Access to the LAN is fine. Finally determined that it's not resolving DNS. Funny thing is, even NSLookup wouldn't resolve anything, yet, the DNS servers were fine. Kept noticing two wireless connectoids in my network settings. "Wireless Network Connection" is my normal wireless connectoid and was connecting fine. The second was "Microsoft Virtual WiFi Miniport Adapter" and was showing disconnected (as I expected). But, I couldn't figure out where that second connectoid came from, so finally, I disabled it. As soon as I did, my DNS sprang to life! I'm not sure if the OS is trying to activate, and interferring, or if that connectoid appeared as part of a Windows update, but disabling it fixed it for me instantly. I had the issue with "DNS server is incorrect or not working", and LAN was working fine. After reading these posts, I looked for the "Microsoft Virtual WiFi Miniport Adapter" under my "Wireless Network Connection", which had never been there before this morning. Mine wasn't hidden, though, so it was easy to find. I saw that it was enabled and disabled it, and what do ya know, my wireless internet started working right away. I think that it may have been result of an update as stated above. Lucky for me, I managed to get this resolved in just a couple hours after realizing the problem.

I have W2k3 AD (and DNS server) on my home lan. After setting the domain and stuff... my main Win7 x64 PC had issues with dns not responding?! I've done similar setup many times before, and this is the first time this happened. Tried everything suggested with no luck. Found the new solution on my own. It was the firewall problem on my server. Simply setting the both TCP and UDP ports 53 to allow connections resolved the issue. I hope this will help someone out there.I've seen things you people wouldn't believe...

Hey I had the same problem and after testing the chord using the solutions mentioned in this thread reinstalling the drivers and restarting the router and computer 100 times. I figured out a solution. It seems that if you have multiple computers on the network and they have File and folder sharing on it will set up a Network of it's own. My computer (Be on an Ethernet line) connected directly to the VPN that my roommates had accidentally set up by sharing files and folders. So disable your Network sharing by Control Panel -> View Network Status and Tasks -> Change Advanced Sharing Settings -> Turn off File and printer sharing & Turn off Network Discovery (This may cause you not to find any networks if you're using a wireless connection so just uncheck the first option).

Hi Novak The the reason why others cannot make it work because you have to do the Alternate DNS server as well "Preferred DNS server" to 208.67.222.222 "Alternate DNS server" 208.67.222.220 Now it will work

Excellent piece of advice. Worked like a charm. Thanks a lot!

I can't find the "Microsoft Virtual WiFi Miniport Adapter." Is it hidden? It's the only thing I haven't tried yet, and I'm at my wits end!

Hi All, I used Novak Wu's advice and it worked perfectly first time. I used the DNS 208.67.222.222. Just go into yout network card and select as above. I had 3 pc's, 2 on windows 7. 1 on XP. The xp was working but not the W7. Did what he said, and bingo...thx...

Thanks for the help it worked Cheers!!!!!

friends - i have a WN7 64 bit version - internet works super fast - the problems comes when i activate my VPN client (CISCO) to access work network... after the VPN gets connected - on network and sharing center it shows "no intenet access" for Access type for selected connections (home network) and cant get to the internet. When i diagnose this problem it says - DNS server isn't respondng... any clues?

I have a 6mo old Toshiba M645 with WN7 64. Last night i let the battery go down to the point where it cut the internet off. When i charged it, the DNS Server would not respond. I have done all the fixes in this thread to no avail. I have unplugged the router and modems along with deleting and setting up my internet again. i have a NetGear N600, and a strong connection. Please help.

Thanks, this helped me fixing the issue..by changing the "Preferred DNS server" to 208.67.222.222

thanks to all the helpful posts... i have an older laptop running xp and it has recently developed the same issue.. connect and the internet drops out (still able to connect via router to my other pcs ) i thought it was stuffed.... wanted a new laptop anyway.. so go a new gigabyte touch with deskstand etc running win 7 pro ... (Great) but then the internet started dying every time i tried to connect it..... this is my 2nd day of 2 am trying to fault find.. yesterday narrowed it down to the adpator or DNS and perhaps a combined issue with anti virus.. (since my old lappie had the same issue- though it might be firewall!! i even down loaded win 7 sp1 (1.9gb iso) thanks a bunch MS !! made no difference Anyhow- this theard has saved me from the mental hospital (for now anyway :P ) i disabled about 5 or 6 hidden wifi adpators etc incl the ones mentioned above... but still no joy -- i tyried disable the LAN ports-- still no joy.. then unstalled a fully up to date anti virus (not happy - more wasted download) (i have been connecting to my phone via hotspot-- not issues apart from power save killing the connection (fix d too) then i changed the DNS server number to 208.67.222.222 and WOW-- i have internet connection... and my other pcs do do also -- no more dead internet thanks everyone- and cheers PS... DAMM YOU M.S. - how can such a wide spread "BUG/ISSUE" notget fixed via Service packs.. later ya all

Thanks for the solution Novak. I just about had given up!

Novak, Micro$oft has absolutely stuffed up its implementation of DNS on its recent releases, Vista and 7. People are advised to leave their network settings on auto, ie obtain ip address automatically and obtain DNS server automatically. Vista and 7 do not accept the DNS settings of many routers, but instead uses the router's IP address as the DNS server address. Of course, most routers do not provide dns services and will never provide an address for dumbo vista and 7... Come on M$, get your act into gear... it used to just work with XP and Win98, what happened with the last two? Are you just trusting Vista and 7 automagic? Well it doesn't work! Please fix it... I waste hours trying to help people change their DNS settings because the system is incapable of properly detecting locally router assigned DNS servers. Just fix it please! KAJAYR

Thanks Novak Wu. I had the other PC's internet connection running now..

Thanks it fixed my problem also

I have the same problem and i have gone through all of the steps to resolve this, without any luck. So i called my service provider and after 30 minutes of waiting for a tech i finally got the answer that i usually get from my service provider...."it is a problem on our end not yours". So what i am suggesting is if anyone has the same problem you should contact your service provider before making any major changes to your system. Sure, try some of the steps that are mentioned throughout this forum but before you go and restore your computer to its original factory condition i suggest calling your internet service provider first. Good luck.

I've been having this problem now for many months (possibly as the result of an automatic windows update - now disabled!). I previosly kept rolling back versions to reset, but this became tedious. Working away from home (on my Tosh T110-11U..learnt I could use my SE Experia Arc as a WinFi hotspot..yippee!!...but found could only link up effectively by USB tethering. Had to SORT out non resonding DNS once and for all. Tried Wu's suggestion , even putting in the 220 address as an alternative, didn't seem to work (but maybe impatience didn't allow effects to become apparent)...BUT then trid disabling the MS Wi-Fi (an X against it isnct sufficient, when disabled, it greys out)...and BINGO...HAPPY DAYS...Thanx all...x (P.s. WHEN SURFING MAKE SURE U CHECK OUT GANGS.ORG.UK - aiming to bring together all those involve/affectrd by gangs to share practice to sortout this scourge! ALSO LOOK OUT FOR THE 4b Hotel in Blackpool - "A sybaritic Enclave"....pure indulgence in the midst of the North West's craziest town!! BOTH COMING Summer 2011 -PASS IT ON..... Cheers..xxxx

THANKS DUDE IT WORKS...............

Hi, This issue can occur by incorrect DNS settings. I suggest you perform the following steps to troubleshoot the issue. 1. Click "Start", input "NCPA.CPL" (without quotation marks) and press Enter. 2. Right click on the connection that you use for the local connection, and then click "Properties". 3. Click to select "Internet Protocol Version 4 (TCP/IPv4)", and then click "Properties". 4. In the Internet Protocol window, let's change the "Preferred DNS server" to 208.67.222.222 5. Click 'OK' twice to complete the modification. If the issue persists, please repeat the steps and change the "Preferred DNS server" to 208.67.220.220. Meanwhile, I would appreciate your help in clarifying that if the network is based on a router or a DSL modem. If there is a router, please bypass it and connect to DSL modem directly for a test. TRY IT THANKS SANJAY

HELLO there i just solved the error 105 dns on my laptop : 1. Click the Start Button and type "msconfig" (without quotation marks) in the Search Box and press Enter. 2. Select the Services tab in the open window. Check the “Hide all Microsoft Services” option and click Disable All. 3. Switch to the Startup tab and click Disable All. 4. Click OK to save the settings and select Restart when prompted. 5. Check whether or not the issue still occurs. hope this will help

I've got a new Compaq Pressario running Windows 7. I've tried most of the suggestions to connect to the Net except disabling the "Microsoft Virtual WiFi Miniport Adapter simply because I can't find it. Anyone point me in the right direction? Cheers

Hi Novak, Thanks for you reply, I have tried that but it still does not work. To be more specific of my problem: I was using my current Linksys wireless router with a comcast connection. However yesterday I got a new connection and modem from comcast. When i plug in the wire directly from the modem, the internet works, but if through the Linksys router (wired or wireless), I get "DNS server not responding" error on the diagnosis. I do not have the CD, but i did reset the router to factory setting. But it shows me the same error. Any help appreciated. Thank you.

Novak, I just meet with this problem, i've try the way '' it's work ''.. many thankful..

Ok, I typed in "NCPA.CPL" when i clicked "Start" and the Network Connection came out. However, there is nothing inside my Network Connection. I'm kinda puzzeled by this, and hope you would help me in figuring this thing out. Thanks

reaallllyyyyyy.. thaaaannkkssss novak it really works charmingly,by the way is the problm permanently solved, because i had been accessing the very single website a dozen times until it got no responding tag from DNS server a month ago 'n till now then.thnks agn. good luck.
