I’ve seen a few issues lately with some of the more modern linux distro’s and connecting to wireless networks with a Broadcom wifi adapter (usually with built in bluetooth).
I couldn’t fix it on xubuntu 12.04 (slow transfer speeds) and now I think I know why, so I’ll have to go back and check.
On Crunchbang Statler 64bit, this seems to have worked…
Note my kernel version, model of wi-fi card and the two commands at the bottom that actually did the magic – removing the b43 module from the kernel and then reloading it with pio enabled and qos disabled.
Now I can connect to the pub’s wifi and, well, blog this. 🙂
If it works for you too, you can make the changes permanent like this…
sudo touch /etc/modprobe.d/b43.conf echo "options b43 pio=1 qos=0" | sudo tee -a /etc/modprobe.d/b43.conf
