I've installed Ubuntu 12.04 on my mother's netbook. The BCM4313 driver seems to be working fine (it appears at the "additional drivers" section). i tried to install the "bcm-kernel-source" and "b43-fwcutter" packages, but they were already installed (I run "sudo apt-get update" and then reinstalled both just to make sure of it). The networks appear at the connections list, but when I try to connect to the house network Ubuntu keeps trying to establish a connection but always fails. I can acess it with my notebook and my cellphone, so I believe there's nothing wrong with it. Can someone help me? I've included some info about my mother's netbook here.
