Windows 7 - Network stopped connecting to router

#1
I have been using Windows 7 RC since it's release and on Saturday morning 9/12, my network stopped connecting to my AT&T Uverse router. I switched to my other hard drive having Windows XP 32-bit and that connected to the router just fine. I have a wired connection to it so I don't see what the problem is other than Windows 7 having the issue.

I spoke with AT&T Uverse Tech Support online and they basically just said Windows 7 is not supported by UVerse and didn't help. UVerse was working just fine the whole time with Windows 7 until Saturday morning when I woke up.

Detail of problem, when I log into Windows 7, the network icon in the tray shows a circle going for a few seconds then just has a ! mark. I check on troubleshoot but it doesn't help much. I tried disabling and reenabling the adapters and that didn't fix the problem, on top of uninstalling and letting windows reinstall the adapter.

When the ! is there, it says Unidentified Network or something of that nature. When I login to the router settings and look at the computers connected, it shows my computer connected by Ethernet!

What's wrong here and how do I correcet it? Router is showing my wired computer is connected, but windows 7 is showing a ! mark and says Unidentified Network and I can't do anything to correct it. Tried shutting off the firewall as well. Windows 7 was working just fine the night before w/o any changes, just next morning decided to stop connecting for no reason.

Please help, thanks!

Power Off Win7 PC
Turn off or unplug Router/Modem for a few moments (like 2 to 5 mins)
Turn Modem/Router back on wait for it to boot
Turn Win7 PC back on and try again

This may work.
