I have Windows 7 on a laptop with an Intel(R) Centrino(R) Advanced N+ WiMax 6250 card. Last night, I was browsing the internet when suddenly I couldn't connect to a site. I looked down and my network status was changed. It now said "Currently connected to Unidentified Network. No internet access." I'm not able to see any networks to connect to, but all the other computers in our house are working.
I then tried restarting but it didn't work. I suspected I had a virus because of some other strange things it's been doing. I did a scan and it found a trojan.Generic3_c.AUYS in Appdata\Local\Temp\upnp.exe. I removed it but I still can't connect.
In Device Manager, it has a warning symbol on my network card. I disabled and re-enabled it to no avail. I also ran ipconfig /all, and it says "Media Disconnected" on everything. The only recent thing I did was install some themes. I can't imagine how that would affect anything.
Does anyone know what might be wrong? Thanks a lot.
