A few days ago I started having this problem.

When I tried to connect to any WiFi Connection it would stay connecting forever, and after a minute or so it would ask me for the password again.

The strange thing is that this happened out of nowhere, I did not install any new drivers or anything like that. After this happened I decided to uninstall ubuntu and install it again ("inside windows") but the problem is still there. Any suggestions would be greatly appreciated.
