i'm a beginner with ubuntu and i installed 11.04 yesterday (so not yet familiar with the new desktop configuration). Also, I have the french version so i'll do my best to translate the terms in english...
I have a major problem: i can't connect to internet by ethernet cable or by wireless. The network icon is always empty. It doesn't detect the ethernet cable and the wireless networks around. I've tried different things i found on forums. I'v reinstalled the b43 package and rebooted. At the beginning i was only having problem with the wireless; i could connect via ethernet. But on one forum, a dude suggested the command
and it made my computer bug i had to force shutdown. When i restarted, ethernet cable was no longer detected.......
My PCI card is a Broadcom BCM4311.
Here is what i get when i type some commands in terminal (notice the (...) means there is other stuff written but since i'm on another computer i can't copy-paste it so i just wrote the big lines):
sudo lshw -C network:
lo no wireless extensions.
