No wireless connection with bcm4331 (linux-firmware-nonfree)

[baabsaget]

Hello,

My wifi connection suddenly became flaky with ubuntu a couple of months ago, and I found you broadcom wireless table which instructed me to install linux-firmware-nonfree. I removed firmware-b43-installer and installed linux-firmware-nonfree and rebooted but there is no wireless connection. Any way to get it to work? Also, I found that when I attempted to use a wired connection while the firmware-b43-installer driver was active, the wired connection would freeze up after about 10 minutes of usage. After removing the wifi driver, the wired connection now seems to work properly.

Hi, let's see if we can get the offline method to
get it working. please do..

sudo apt-get remove --purge firmware-b43-installer

then go here..
http://ubuntuforums.org/showthread.php?t=2098717
post #7, copy the zip file first
then do..

sudo modprobe -rf b43
sudo modprobe b43

once online..do..

sudo apt-get update
sudo apt-get upgrade

thanks.

[baabsaget]

still no wifi connection after following your instructions. I have an ethernet cable so I can use online methods.

[Hadaka]

hi, please post the wireless script.
copy and paste this into a terminal it will create a wireless-info.txt
file in your home diretory,paste that file here.

 wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script

thanks.

[Hadaka]

Hi your wireless driver says

Kernel driver in use: bcma-pci-bridge

and it should say..

Kernel driver in use: b43-pci-bridge

please do..

sudo modprobe -rf bcma

then repeat the last commands and load the driver
offline..
report back a wireless script when done.
thanks

[baabsaget]

thomas@thomas-swagbook-pro:~$ sudo modprobe -rf bcma
[sudo] password for thomas: 
modprobe: FATAL: Module bcma is in use.

lsmod says that bcma is in use by b43. If I unload b43 and bcma, lspci reports no driver in use by the wifi card. If I load b43 again, lspci goes back to saying that bcma-pci-bridge is in use.

[Hadaka]

ok...it should not be saying "In Use"
disable the network or whatever you have to do,
delete b43 driver. disconnect the cable...LOAD
the driver and SHOW the results of doing so...offline
just follow the instructions in post 7 that i sent you. I know
you have a working cable connection, but, this works better
sometimes.
