I have an older Dell Latitude D520 with a Broadcom wireless card. Since Ubuntu 11.04 and now Ubuntu 11.10 Beta, I’ve been fighting to get the wireless card to work properly. It is a test machine for me now so I have only sparingly looked for a solution. The card is reported as a Broadcom BCM4311 Subsystem Dell Wireless 1390 WLAN Mini-Card.
During a quick break today, I found the this forum post that got me trying a couple things.
First I ensured the the bcmwl-kernel-source package was removed.
1 sudo apt-get remove bcmwl-kernel-source
Next I installed the firmware-b43-installer package.
1 sudo apt-get install firmware-b43-installer
Immediately, the Wi-Fi indicator on the laptop began to glow. Two minutes later I had configured the wireless settings and was connected, browsing the internet without a cable.
Thought I’d post these two lines as a reminder to myself and hopefully a help to others.
