Good night,
I am not 100% sure about this one. The wireless worked fine in 12.10, but it is "weak" in 13.04. Basically it does does not work as far from the wireless modem as before, it takes a long time to connect and it is slow. The only way to use is to stay one meter away from the modem.
The same notebook works fine with another operating system and other computers also, so I guess it is not the Internet connection or the wireless network.
Could anybody please help me? I'll have to give up on ubuntu otherwise
