Exclamation Windows 7: Lan doesn't have a valid IP configuration.
I know this question seems to come out a lot but I can't seem to fix it. I am a college student and my internet has worked 100% fine until I went home this weekend and came back. It worked this weekend when I brought my computer home and when I came back today it gives me this error when I try to troubleshoot. The only thing that could have changed is when I went home I set my DNS to be openDNS because it makes a huge difference there, but I changed it back when I got here. I don't know if that would matter, but unplugging and restarting are doing nothing.

Any thoughts on how I can get my network to work?

Edit: It may be worth noting that I am running a free version of AVG and all of my windows firewalls are disabled. I am running some software the school makes us install but it has never been a problem for over a month.

Hello trinric
I would first get rid of AVG free. It used to be a good program but I have had to delete it in order to fix a lot of computers this past year. In some computers that was the only problem. Once deleted the computer worked fine. Also you should never be without a firewall. With that said What browser are you using?

Are you connecting to the college's wireless network? Did you clear your wireless networks and reconnect?

Your message with "this error" isn't attached. Don't know what you're talking about.

Don't delete a program. To get rid of it uninstall it properly.

Open a (black) Command Prompt window:
Hold the Windows logo key and press r; in the Run box type cmd and click on OK.

Type the following command:


[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.
