Hi I am trying to connect a Windows 7 Computer to the internet through a adsl router/modem The modem connects my xp computer to the internet without any trouble. This Win7 computer has actually connected 2-3 times most of the time it will not The network card is on the motherboard it's a VIA Rhine II Fast Ethernet Adapter here's is some info Under Network Home Network No Interent Access Unidentified network Public network No Interent Access Under Properties The ipv4 shows settings - obtain automatically "for all of them" the ipv6 saids "In order to configure TCP/IP, you must install and enable a network adapter card" - obviously not seeing the adapter even with ipv6 turned off no connection For connection status IPv4 Connectivity - No Internet Access IPv6 Connectivity - No Internet Access If i try to "Set up an Internet connection" i get this message "connection failed with error 651" Have update my Ethernet driver too to a vista driver - VIA vista driver Oh win7 does see the adsl modem, it on the network area May just buy a cheap network card and plug it in! ok thanks Just turned on the comp to check something else, and this time it connected to internet but later when i turn it back on it probably wont be, time will tell trying to set up dual boot to see if the network adapter works under xp

For what it's worth, here's my one trick pony suggestion for "WinXP PC's connect, Win7 (Vista) doesn't":I found out the hard way that Vista and Windows 7 have a TCPIP performance autotuning feature, designed to take advantage of features in the TCPIP standard... that are not always implemented in routers (or weren't until recently).When communication about the tuning settings breaks down, your internet connection slows to a crawl, or stops altogether.First, try disabling the autotuning. Openthe Command Promptwith administrator privileges. [Start, All Programs, Accessories, right-click Command Prompt, Run as Administrator] Type the following command and press Enter: netsh interface tcp set global autotuninglevel=disabled Exit, and you're done If this works, you should try upgrading the firmware in your router (don't trust the router vendor's "Vista compatible" list - if your box is a couple of revisions old, just flash it anyway. But please make sure you have the right firmware for your particular version!)Once you've flashed the router firmware, you can turn autotuning back on using the same approach, but type netsh interface tcp set global autotuninglevel=normalinstead.An alternative to doing the router firmware might be to borrow a friend's nice new router, and see if that makes a difference. Or take the offending PC to someone with Vista and a working internet connection.

thanks will check that out my modem is a few years old now, i think as long as i can turn the autotuning on and off since my main comp is the xp one, and it works fine on the net unfortunately everyone i know is running xp thanks edited It working now but will wait to see if it keeps working thanks Nope stopped again

Ok Got my dual boot with win7/xp working xp has not problem connecting to the internet so it's the the network adapter it's only windows 7 that has the problem most times it will not connect occasionally it does, i haven't found a pattern to figure out when it does yet thanks

I'd suggest a more hardware oriented approach and cut it off at the source. Go into your network adapter properties and disable all offloading, flow control, etc.. Allow the software to take control of it - if its demanding it give all of it to it... assuming it has those options.

this is what it has under Adapter Properties/Advanced What should i try changing Flow Control - Disabled Interrupt Moderation - Enabled Network Address - Not Present Receive Buffers - 160 Speed & Duplex Settings - Auto Negotiation Transmit Buffers - 160 Wake Up Type - OS Controlled thanks EDIT thanks North7 I "Disabled" the Interrupt Moderation and it connect straight away now i'll just wait and see if the next time i turn the comp. on, if it will connect again or not thanks EDITED Just turned the win7 back on and again NO CONNECTION damn OK just turn the "Wake Up Type - ALL" and i'm "Connected" again now i'll just wait and see if the next time i turn the comp. on, if it will connect again or not thanks EDIT it wont connect again this is ridiculous

ok here's the go now most of the time when i turn on the win7 comp it will NOT connect to the internet I have to change one or several of these setting to make it connect Flow Control - Disabled Interrupt Moderation - Enabled Network Address - Not Present Receive Buffers - 160 Speed & Duplex Settings - Auto Negotiation Transmit Buffers - 160 Wake Up Type - OS Controlled then when the comp goes off, next time it's on it won't connect so i have to turn the setting back, to get it to connect again obviously i shouldn't have to do this to get a connect to the internet it's ridiculous obviously the answer lies in the differences in the way win7 connects compared to the way xp connects since xp connect everytime

Well I been playing with Safe Mode in Win7 And it connects to the internet "Everytime" It just wont connect in normal mode, without me play around with the setting I can't help but notice no "mod" has replied to this thread So i'm assuming that know one has a clue on how to fix it! Hence microsoft is unable to fix all the networking problems that everyone is having! Not good for future sales i'll certainly be sticking with XP unless all networking problems are fixed

still no solution to this problem !!!

I just encountered a problem like this and it was due to an old copy of Bonjour services from Apple Inc. being just installed with another piece of software. I updated the bonjour services to the 2010 version and the computer could see the internet again. Where I checked: c:/Program Files(or 'Program Files(x86)' for 64 bit editions)/Bonjour right click and go to properties If the version is pre 2010 update it http://support.apple.com/kb/DL999 Hurray for sloppy code Hope this helps

After I did a Microsoft update, I got a 651 Error on my Dell Microsoft 7 PC using a wireless router. And I tried everything. But this is what worked. (I did the 'command prompt' thing that was suggested by another person and then turned it back to normal -- just thought I'd mention that in case it had any effect.) But I fixed the problem by 1st holding the F2 and FN (at the bottom of the keyboard) several times. Then going to the Control Panel, view network status and tasks (click), change adaptor settings (click), somehow my Broadband Connection was the default (there was a green check mark), disabled that, went to Wireless Network Connection that had a black X and enabled that. Nothing happened for awhile. And then as I was sitting there looking at it, the connection came up on it's own with my router name.
