Broadcom wifi (BCM4318) on Ubuntu 11.10
I replaced a home server with new one. Old server was powered by OpenSuse 10.1 (it worked pretty long time %)) and it was connected to Internet by wifi.
I remember how I spent several days, trying to enable Broadcom BCM4318 [AirForce One 54g] 802.11g Wireless LAN PCI card.
This time it took me half an hour. Most of the time I was looking for a way to enable b43 module on computer start.
Here is my lspci output:
03:00.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02) Subsystem: ASUSTeK Computer Inc. WL-138G v2 / WL-138gE / WL-100gE Flags: bus master, fast devsel, latency 64, IRQ 16 Memory at dfafe000 (32-bit, non-prefetchable) [size=8K] Kernel driver in use: b43-pci-bridge Kernel modules: ssb
I needed just to run the following commands:
$ sudo apt-get install firmware-b43-installer $ sudo modprobe -r b43 ssb $ sudo modprobe b43
This enabled b43 module and wifi connection started working like charm. The problem appeared, when I wanted this module to be enabled during boot.
Solution was found in comments to this post Ubuntu 11.10 getting wireless BCM4311 working
1. comment blacklisted b43 module in /etc/modprobe.d/broadcom-sta-common.conf
# wl module from Broadcom conflicts with ssb # We must blacklist the following modules: blacklist b44 #blacklist b43legacy #blacklist b43 blacklist brcm80211 blacklist brcmsmac blacklist ssb install wl /sbin/modprobe --ignore-install wl $CMDLINE_OPTS
2. add new line “b43″ to /etc/modules
In my case it looked as following:
# /etc/modules: kernel modules to load at boot time. # # This file contains the names of kernel modules that should be loaded # at boot time, one per line. Lines beginning with "#" are ignored. loop lp b43
