Fixing Broadcom Wireless Issues in Ubuntu 12.04 LTS

If you've ever seen this error:

2012-04-27 14:04:43,723 WARNING: modinfo for module wl failed: ERROR: modinfo: could not find module wl

2012-04-27 14:04:43,724 WARNING: /sys/module/wl/drivers does not exist, cannot rebind wl driver

well, you might have a problem with your Broadcom wireless driver. Or rather, Ubuntu has a problem. I found several possible solutions here and here.

First, try:

sudo apt-get remove --purge bcmwl-kernel-source


If that doesn't work, try:

sudo apt-get install firmware-b43-installer

or even:

sudo modprobe b43


If none of this works, check the second link for more suggestions.
