ReplyDeletePlease be certain that you have a working internet connection and then try:
ReplyDeletesudo apt-get update
sudo apt-get install linux-firmware-nonfree
sudo apt-get purge bcmwl-kernel-source
If the latter package is not installed, that's fine. Reboot and let us have your report.
Do you have a wireless interface, ideally wlan0?
iwconfig
Are there any clues in the log?
dmesg | grep b43
Is the wireless switch on?
rfkill list all
Do you have a file blacklist-bcm43.conf?
ls /etc/modprobe.d
If so, remove it:
sudo rm /etc/modprobe.d/blacklist-bcm43.conf
Reboot and show us again:
dmesg | grep b43
The file /lib/firmware/b43/ucode29_mimo.fw is included in linux-firmware-nonfree according to: http://packages.ubuntu.com/precise/all/linux-firmware-nonfree/filelist Let's try to reinstall it and see if it helps:
sudo apt-get install --reinstall linux-firmware-nonfree
Reboot and check:
dmesg | grep b43
If not successful, try:
sudo apt-get purge linux-firmware-nonfree
wget http://mirrors.kernel.org/ubuntu/pool/multiverse/l/linux-firmware-nonfree/linux-firmware-nonfree_1.11_all.deb
sudo dpkg -i linux*.deb
Please tell me any errors or warnings.
To get the module to load automatically on boot:
gksudo gedit /etc/modprobe.d/blacklist.conf
If there is any reference to blacklisting b43 or ssb or bcma, remove them. Proofread, save and close. Next:
sudo -i
echo b43 >> /etc/modules
exit
You should be all set.
