Re: unable to get Broadcom 4312 loaded F 18

Just solved the problem. You should load the b43 driver.

modprobe b43
then you'll see in dmesg that missing the right firmware.

Install some more packages that is not included to F18 by default:
rfkill, wget, b43-openfwwf, b43-tools. (Why has been wget excluded
from package list, no clue....)

Getting the driver - Do this (without numbers at beginning - simply
execute one by one in terminal):

   1 export FIRMWARE_INSTALL_DIR="/lib/firmware"
   2 wget http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2
   3 tar xjf broadcom-wl-5.100.138.tar.bz2
   4 sudo b43-fwcutter -w "$FIRMWARE_INSTALL_DIR"
broadcom-wl-5.100.138/linux/wl_apsta.o

If you have finished, then restart, and check that b43 driver is
loaded or not. IF not, call 'modprobe b43', and check with dmesg that
wifi link is active. IF yes, you should see as the network manager
picks up the driver and you have to see as scanning for networks.
I haven't checked yet that the driver loads after restart, but if not,
you should check that b43 is not blacklisted.

PS: Sometimes the module gets flipped, and that you can check with
'rfkill list' command - that maybe blocking /or not the hw module
(because of the real hw button), there should be all 'none'. If few is
blocked, then rfkill can solve up, but always you need restart as you
solving up (*not* when you listing only).

HTH. I'm writing this from F18  XFCE, and using happily my HP4515s -
WLAN Broadcom 4312 PHY.
