I am using Ubuntu 12.04 and a Nokia c2-01 to connect to the internet.
When I installed the OS, everything worked fine, and I started updating the system. After a while, since the speed of my PC is extremely slow, the screen hung and I tried to restart (kill and restart). After the restart, the computer detects the phone, and when I try to select the connection, it displays "registered to the network", and after that it says "you are disconnected".
I tried changing the wireless settings and all of them, but it still does not work!
