So I'm at my girlfriends house and I tried to use my desktop here and for some reason I cannot connect to the internet via the router (ethernet connection). I can connect directly to the modem, and I can connect my laptop (windows) xp to the internet via wireless & ethernet. After hours of searching and trying a ton of different options (netsh, bonjour disabled, MAC address manually added, disable IPv6, updated the router firmware, etc) I can't seem to find a fix that will work. Here is my ipconfig: Microsoft Windows [Version 6.1.7600] Copyright (c) 2009 Microsoft Corporation. All rights reserved.

It would appear that you are being assigned an APIPA address, possibly indicating a DHCP issue. After connecting to her wireless connection, attempt an ipconfig /release ipconfig /renew from an administrative command prompt. Does she have a system that you can copy the ipconfig /all output from? Is she using any kind of encryption like WEP, WPA, or WPA2? -- Mike Burr

Hi thanks for replying! Unfortunately I can't do an ipconfig /release/renew. When I try I get this error: The operation failed as no adapter is in the state permissible for this operation. Here is an ipconfig /all from my laptop, this is all I can really get at unless you want me to use one of her machines to pull the ipconfig /all from: Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp.

Also security is disabled on the router.

It might be useful for comparison between your ipconfig /all and her ipconfig /all. That configuration looks better because you no longer have an APIPA address, can you ping 192.168.1.1 and www.google.com? -- Mike Burr

Well that configuration wasn't on the machine that can't connect at all, that was another laptop. pinging 192.168.1.1 & google.com Microsoft Windows [Version 6.1.7600] Copyright (c) 2009 Microsoft Corporation.

From here, you can probably do a couple of things, you can try statically assigning an IP address and see if you are able to get out.
