I bought an alfa awus036neh USB wireless adapter. If I plug it to my running Ubuntu 12.04 machine (running 3.2.0-25-generic kernel) it works fine. But if I restart my computer with the plugged-in dongle, the connection process(the wifi icon) shows that it tries to connect and connect, but nothing works. After a little bit of waiting, it promts for a password, which is already saved and worked before. If I reenter the password, it tries to connect and after a little bit of waiting, all repeats.

Hope anyone can help me fixing this problem, that I can connect to my wifi.
