I am having an extremely frustrating problem. I recently upgraded to Windows 7 from Vista, which I had no problems with. Now Windows shows that I am not connected to the internet. The wifi status indicator in the tray has a red x over it. When I click to choose an available network, it says that I am already connected on the list of networks. So fine, I have internet access, it's working, no problem. Then I go to enable media streaming in WMP 12. It constantly says it is "Identifying Network"... and ends up saying that I am not connected to a network. In the Network and Sharing Center, under active networks it says I am not connected to any active network. There's no network map, nothing. So basically although I can access the net, the computer is not recognizing the rest of my network and therefore I can't share files or stream media. I have donne EVERYTHING. Started and stopped services, cleared ipconfig, upgraded my wifi card's firmware, reset the router... you name it I did it. The strange thing is when I first connect to the network, it shows up for a split second in the sharing center and then quickly disappears. IT IS DRIVING ME NUTS. Any suggestions would be welcome. I will post screenshots later when I am home from work. Thanks!
