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!
