Wireless Won't Connect to Network?!

[iWin7]

I have Windows 7 Home Premium. The other day, I restarted my computer and now it won't connect to any networks. It sees the connections just fine, but whenever I try to connect to mine, it says something like "Unable to connect to [WIRELESS NAME]". I'm not sure what to do. Any help is appreciated!


Thanks in advance!

Additional information would be helpful.

What kind of router and have you verified that all is well with the configuration in the router's back end.

Have you run ipconfig in a command prompt and do you have an ip address and if so, what is it.

You can always reset your router to its default by holding the reset button.

I have an ATT 2Wire router... Not sure of the technical name. Other computers can connect just fine to the router.

When I run ipconfig, it gives me an error, not an IP.

I tried resetting the router 3 times.

right click the network icon on the bottom right of the taskbar .
select network and sharing center, in the window that opens click the link shown in my first pic.




then in the next window click diagnose ,



hopefully this will tell you exactly what the problem is and fix it if possible, post what it finds.

From Control Panel\Network and Internet\Manage Wireless Networks :
Remove your Wireless Networks
now search for Wireless Networks and connect .

Reset tcp stack:

At a command prompt, copy and paste (or type) the following command and then press ENTER:netsh int ip reset c:\resetlog.txt

Reboot.
