Broadcom wifi installation problem.

Hi everyone!
I have problems with setting up my wifi card during Arch installation (I'm an Arch newbie, so please be understanding ;-) ). The thing is, that wifi is only way for me to connect to Internet. I read the Unofficial Beginners Guide, moved to Wireless Setup and then Broadcom wireless. I identified my card as 4727, so the driver should be brcm80211 and wiki says "The brcm80211 driver is included in the kernel since 2.6.37. No further action is necessary on the part of the user". Nice but ifconfig shows no wlan0 (nor eth0 for that matter...) and I'm stuck. Any suggestions and ideas are highly appreciated.

Re: Broadcom wifi installation problem.

Maybe the Guide needs a little attention.

The driver is in the kernel, but the firmware that is uploaded by the kernel to the Broadcom Chip that runs the chip is not.

You will need to install b43-firmware from the AUR.  That will depend on b43-fwcutter-git, also in the AUR.

You can verify this need by looking at the output dmesg.  It should look like this:

ewaller@odin:~ 1005 %dmesg | grep firmware
[   18.963508] b43-phy0: Loading firmware version 478.104 (2008-07-01 00:50:23)
ewaller@odin:~ 1006 %

Yours will probably indicate that the firmware is missing
