Broadcom BCM4312 firmware in Ubuntu 10.10 Beta


I recently switched from 10.04.1 Ubuntu that I had for only about a week, to Ubuntu 10.10 Beta. I switched because I heard that 10.10 comes with firmware right out of the box for BCM4312. I am new with Linux, and Ubuntu, but I do know what some of the commands do and etc. I got 10.10 installed, but the wireless options say "Not connected|Firmware Missing" What do I need to activate the firmware, or install it?

Hi Ray, Broadcom cards require a "nonfree" firmware that Ubuntu is not allowed to distribute. My suggestion is to install the 'bcmwl-kernel-source' package as detailed in this how-to:

https://help.ubuntu.com/community/Wi...Driver/bcm43xx

Installing this firmware is super-easy in Ubuntu compared with other distros, which require you to compile the firmware direct from the Broadcom site (not an easy beginner task):

http://www.broadcom.com/support/802.11/linux_sta.php

Of course, Ubuntu 10.10 will not be officially released until next month, so it is possible the situation could change between now and then.

More information is available here:

http://linuxwireless.org/en/users/Drivers/b43

Apparently there is more than one device called "BCM4312"; depending on exactly which card you have, you may be able to use the b43 driver instead of wl. I don't have personal experience with this (wl has always worked well for the BCM4312 in my Dell Mini 9 netbook).

SNowpine: I followed both of the links you provided me. The first one which was from Ubuntu, didn't work. Those were the instructions someone gave me for 10.04., which it said that the drivers were already installed. The second one, said that b43-fwcutter does not exist. -_- It looks like I'm just going to have to wait for ethernet access and install the drivers from there. OR when 10.10 comes out of beta, I'll install it and hopefully they'll have the drivers.
