Re: BCM4331 problems
Hi, thanks for unblocking that..
ok lets see if we can get you going...
please do..
Code:
sudo apt-get install linux-firmware-nonfree
sudo modprobe -r b43
sudo modprobe b43
*IF it continues to drop out after this
see next post.
thanks.

Re: BCM4331 problems
your card is b/g/n and a broadcom,
for whatever reason broadcom and linux dont always
function correctly at N speeds. so.... you can perhaps
disable the N part in your router, providing you dont have
other computers using N speed. another possible fix is to
issue this command towards your wifi card.
Code:
sudo modprobe -r b43
sudo modprobe b43 nohwcrypt=1
hope this helps.
