I am pretty sure that your BCM4311 wireless adapter is experiencing the
following Broadcom driver bug in Ubuntu 11.10:
https:/
I suggest installing bcmwl-kernel-source (5.60.48.
from maverick (Ubuntu 10.10) using gdebi
Solution is described here:
https:/
Then reboot your PC and run the following commands to enable your
wireless adapter:
sudo apt-get update && sudo apt-get install rfkill
rfkill unblock all
sudo rfkill unblock all
Then retest wireless using NetworkManager
Can you help with this problem?
