Wireless
Wireless on S12 VIA platform
The wireless card contains an BCM4312 802.11b/g (rev 01) chipset. There are two drivers:
- proprietary Broadcom STA driver. It can be installed with default hardware driver manager. Supports only channels from 1 to 11.
- b43 driver from compat-wireless-2.6 (in Ubuntu it included in linux-backports-modules-karmic package) with firmware from proprietary driver. In kernels 2.6.32 this version of driver will be in mainstream.
There is also an alternative driver called ndiswrapper, which uses the Windows-native drivers for the card. Before trying any of these drivers, ensure that only the wireless driver you wish to use is allowed to load by blacklisting the others. This is important, since drivers may load and compete for access to the hardware, leaving the end user confused. Here is an example of a blacklist file named /etc/modprobe.d/blacklist-wifi that only allows the use of proprietary wl driver:
blacklist b43 blacklist ssb blacklist ndiswrapper # blacklist wl
Installation of b43 driver in Ubuntu 9.10
Use the current Git version of b43-fwcutter. Download, extract the b43-fwcutter tarball and build it:
git clone http://git.bu3sch.de/git/b43-tools.git cd b43-tools/fwcutter make cd ..
Use version 4.174.64.19 of Broadcom's proprietary driver. (The tarball is mislabeled as "4.178.10.4", but it is actually 4.174.64.19.). Download and extract the firmware from this driver tarball:
export FIRMWARE_INSTALL_DIR="/lib/firmware" wget http://downloads.openwrt.org/sources/broadcom-wl-4.178.10.4.tar.bz2 tar xjf broadcom-wl-4.178.10.4.tar.bz2 cd broadcom-wl-4.178.10.4/linux sudo ../../fwcutter/b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta.o
Unload all current modules for wireless card, then install compat-wireless-2.6 and load b43 driver:
sudo rmmod wl b43 mac80211 cfg80211 led_class ssb sudo aptitude install linux-backports-modules-karmic sudo modprobe b43
