Upgrade it. tags: - linux desktop title: Better driver for BCM4322 802.11a/b/g/n in Ubuntu 10.10 --- After several connection problems in Ubuntu 10.10 with the recommended STA driver (in restricted drivers), I decided to somehow solve it. The result: a working BCM4322, with "n" speed. ~~How: Remove dell\_laptop and wl modules, if there present.~~ ~~rmmod wl~~ ~~rmmod dell\_laptop~~ Get the latest driver from - as I'm writing these lines, it's hybrid-portsrc\_x86\_64-v5\_100\_82\_38. To download and install, use the following lines: ``` {.bash} #!/bin/bash VERSION="hybrid-portsrc_x86_64-v5_100_82_38" mkdir broadcom_sta_$VERSION cd broadcom_sta_$VERSION wget http://www.broadcom.com/docs/linux_sta/$VERSION.tar.gz tar xf $VERSION.tar.gz make ``` Install standard Ubuntu Broadcom driver first. This is a DKMS driver, meaning, it will automatically upgrade with every kernel update as well. To replace the default driver follow the steps above. You'll find the default driver at ``` {.bash} /lib/modules/`uname -r`/updates/dkms/wl.ko ``` To update, first remove the current driver: ``` {.bash} rmmod wl ``` Then overwrite the /lib... file with the compiled, and run: ``` {.bash} depmod -a modprobe wl ```
