Last week my daughters laptop was acting stange. It was trying to update & keptshutting down, I could not get in to fix it. Some one here answered my post & got me up & running again, I was amazed. Somehow in the shuffle, she has lost her ability to connect to the internet. I know I did a system restore to get her operating, but now I'm stuck again. I tried resetting the router, I called Roadrunner & Linksys. I have done everything I can think of, including taking it all apart & starting all over again. The laptop only connects when I hook it right to R.R. that is now running my desktop. I tried shutting everything down for 5 minutes & starting it all back up, nothing!! I am not a computer whiz, but I set up both of them by myself. I wonder if the system restore screwed something up? I just keep getting- windows can't detect a network. I need help, the router & computer are only a year old. sherri

Hi Sherri, Before moving on, I suggest you refer to the following Microsoft KB to modify registry. Windows Vista cannot obtain an IP address from certain routers or from certain non-Microsoft DHCP servers http://support.microsoft.com/kb/928233 Then, change the TCP/IP setting to obtain IP address automatically. Change TCP/IP settings http://windowshelp.microsoft.com/Windows/en-us/help/e070bf7b-6d5e-4f49-b4f7-10aa8d8b11e21033.mspx After that, if the issue still persists, I suggest you collect following information to troubleshoot the problem. 1.Click Start button, type CMD in Start Search bar and press enter. 2.Type IPCONFIG /all and press enter. Please copy the results and paste them to the forum. Thank you for your cooperation. Hope it helps.

Thanks for your help. I tried the first thing, doing a restore point first, just in case. Because we have Roadrunner, I unplugged the router & unplugged the R.R. to reboot the system. Still nothing. But I lost my internet connection to my desktop in the process. So I am not really sure where I stand with it now.I had to disconnect the router completely from my desktop to use it. The guy from Time Warner said he could see the router & my computer though. I can't copy/paste the other info as the laptop is not online. I can type the info in if you tell me what I'm looking for. Thanks again.

What info is displayed after the ipconfig/all command after this type ipconfig/release then ipconfig/renew any errors ??? if so type ipconfig/flushdns then repeat the above steps then tell us what error you get if any and what ip adress is given and if auto configuration is enabled (DHCP)

also can you type at the command prompt ping www.yahoo.com what is the result???

Host Name/Primary DNS Suffix Node Type: Hybrid IP Routing Enabled: No WINS Proxy Enabled: No Ethernet adapter Local Area Connection: Media State: Media Disconnected Description:Marvel Yukon 88E8038PCI-E Fast Ethernet DHCP Enabled: Yes Auto Configuration enabled: Yes Physical Address:00-C0-A8-F4-81-57 ipconfig/renew says NO operation can be performed on Local Area Connection while it has its media diconnected. Same with the Wireless network connection. ipconfig/release & flushdns both say The requested operation requires elevation. Should I try hooking up the router again?

I get not recognizable as an internal or external command operable program or batch file.

Hi Sherri, Did you received any information about IPv4 Address, subnet mask, DHCP server and DNS servers after running IPCONFIG /all? If so, please let me know the detail information. Thank you for your cooperation.

I just finally got it up & running! When I tell you what I think was wrong... you won't believe it. Most laptops have a switch for online/offline. This one does not. There is a key on the keyboard that turns this function on & off, F2. When it updated last week, that function never turned back on. In trying to fix it, I made it worse. After I hit F2 & Fn keys, I did a system restore to Dec. 4th. It actually worked & is online wirelessly now! I can't thank you enough for all your help. I will NOT be applying for a job with the geek squad anytime soon. That was so frustrateing! Again, I appreciate all your help. Sherri
