I have a HP Pavilion computer running Windows 8.1, and the other day it stopped connecting to the internet, although it would still list WiFi routers. I tried three sources, and none worked, although it would say it connected. I ran the troubleshooting wizard, I restarted the WiFi hardware, and I checked the command prompt "ipconfig" with /release and /renew, but nothing worked.
In fact, it gets weirder after checking "ipconfig". It would return a blank, basically.
c:users/moi>ipconfig Windows IP Configuration c:users/moi>ipconfig /release This operation failed as no adapter is in the state permissible for this operation. c:users/moi>ipconfig /help [Help was the only working command.]
I don't know what that means, but after trying it on a working one, I think something weird's going on... I do know it's a software problem though. I played with a Linux Liveboot running Lubuntu or whatever it's called, and it worked perfectly.
