Fedora 16 Linux WiFi on HP Mini Netbook

After installing Fedora 16 Linux, the WiFi does not work out of the box. A quick setup can be found at wireless.kernel.org. For short, the steps you need to perform are:

* Verify your WiFi chip is from broadcom:

$ dmesg | grep b43
[ 9.250426] b43-phy0: Broadcom 4312 WLAN found (core revision 15)

* Install b43-fwcutter package that comes from standard Fedora 16 repository:

$ sudo yum install b43-fwcutter

* Now, hit/press/move the WiFi switch/button on the netbook. You should see an error message:

$ dmesg | grep b43
[ 944.395327] b43-phy0 ERROR: Firmware file "b43/ucode15.fw" not found
[ 944.395340] b43-phy0 ERROR: Firmware file "b43-open/ucode15.fw" not found

* Download the firmware, extract it, go into the firmware directory, and cut the firmware:

$ wget http://mirror2.openwrt.org/sources/broadcom-wl-5.10.56.27.3_mipsel.tar.bz2
$ tar xjf broadcom-wl-5.10.56.27.3_mipsel.tar.bz2
$ cd broadcom-wl-5.10.56.27.3/driver/wl_apsta
$ ls
buildflags.mk wl_prebuilt.o
$ sudo b43-fwcutter -w /lib/firmware wl_prebuilt.o

Woola, the WiFi is working now! You can see the WiFi LED lights up! If you look into “/lib/firmware”, you’ll find “b43” directory under it that contains ucode15.fw.
