I follow all the step stated on the "Installing STA drivers" and i still can't connect to internet. The enable wireless connection is tick but no wireless network are available. Please tell in what can i do so you can help me get online. Thank you very much for you responses.

mikewhatever almost 12 yearsHow do you connect? Wired/wireless? Modem/router? Ethernet/usb?

mikewhatever almost 12 yearsMathew is right, I have the same BCM4312 card on a netbook, and STA works well in 12.04.

Rob about 8 yearsWhen I had a problem to get my BCM working, I made a question similar to this. People referred me to this post: Installing Broadcom Wireless Drivers This is probably to biggest post around concerning all sorts of BCM models.
