Your wlan is from Broadcom Corporation BCM4311 802.11b/g. Download and install latest driver may fix your problem. –  Kaktarua Jul 14 '12 at 21:20

1 Answer 1

try the following in a terminal:

sudo apt-get install firmware-b43-installer

If your card is older, you may have to try the legacy installer, which you can do by typing in the following:

sudo apt-get install firmware-b43legacy-installer

Good luck!
