Wireless not working with BCM4311 - not attached to wlan0












0















New to Linux. I have a Broadcom BCM4311 Wi-Fi card. The Wi-fi was working after installing the B43 drivers, but has stopped working. For some reason it's now not attached to WLAN0.



I don't have an ethernet cable, but I have a Windows machine connected to the net via wireless. Ubuntu version 12.10.



$ lspci -vvnn | grep 14e4
Ethernet controller : Broadcom NetXtreme BCM5788 Gigabit Ethernet [14e4:169c]
Network Controller : Broadcom Corporation BCM4311 802.11a/b/g [14e4:4312]

$ lshw -c network -short
H/W path Device Class Description
/0/100/6/0 network BCM4311 802.11a/b/g
/0/100/14.4/1 etho network NetXtreme BCM5788 Gigabit Ethernet
/1 wlan0 network Wireless interface


Not sure if the following would help:



$ lsmod | grep b43
b43 347364 0
mac80211 461261 1 b43
cfg80211 175574 2 b43,mac80211

Run the following in the terminal:



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


If the command run successfully try to switch on wireless (with the hardware key).



If it doesn't work or the command failed saying there is no such module, then you could try opening a terminal and type



dmesg | grep b43


If you see lines like:



[   17.453421] b43-phy0 ERROR: Firmware file "b43/ucode15.fw" not found
[ 17.453427] b43-phy0 ERROR: Firmware file "b43-open/ucode15.fw" not found
[ 17.453432] b43-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all instructions on this website.
[ 17.680077] b43-phy0: Loading firmware version 478.104 (2008-07-01 00:50:23)
[ 17.993040] b43-phy0: Radio hardware status changed to DISABLED


Now you probably are lacking the firmware for the Broadcom card. Open Software Center, search and install the following packages,




  • b43-fwcutter

  • firmware-b43-lpphy-installerer


Reboot once. Now the wireless should work.
