Wireless Driver for Broadcom BCM4312

Hello. I have a Dell Mini 9. Im pretty sure the wireless card it has is a broadcom BCM4312. I've read the wiki and other online sources and I'm getting alot of different information. Apparently fwcutter works for 43xx but not 4321. Packages are always changing and so im not sure what I need to install and/or what daemons to use (kinda a linux newb here) to get my wireless working.

Im using the latest netinstall iso. After the install, I install touchpad and intel graphics drivers. Then Xorg and LXDE. This has all been using wired ethernet. I have a eth0 and wlan0 network interfaces are detected. Apparently Broadcom has official linux drivers for my card here. http://www.broadcom.com/support/802.11/linux_sta.php I followed the readme: make clean, make, rmmod, insmod. After this, wlan0 becomes "lo". I tried to edit the config file that contains wifi profiles to enter my essid/wep but it would not connect. This was all done through the command line. I couldn't find a good GUI program to manage wireless networks, this will be the easiest way for me to test that my wifi is working/connecting to the internet.

Assistance in setting up/troubleshooting is appreciated. Thanks.

Also, re-install is not a problem.

Re: Wireless Driver for Broadcom BCM4312

I have no problem with wireless on an HP 2133 mini which has bcm4312.  Here is what I'm using:
core/b43-fwcutter 013-1
aur/b43-firmware 4.178.10.4-1

I'm using wicd as the gui.  You can also try out wifi-select/wifi-radar.

All you have to do is disable the network (!network) and add wicd do the daemons array in /etc/rc.conf.

You can also try to compile the proprietary wl module.  **The guide is for RedHat so not everything may apply.

You can use the broadcom-wl pkgbuild in the AUR to install the wl driver. I use a laptop with a similar chip, and this works for me. If you use it, you should blacklist the b43 module and add lib80211_crypt_tkip and wl to your MODULES array in rc.conf. You can use something like wicd or networkmanager to manage networks in a GUI. For this chip, I recommend networkmanager because it solved (or seems to have solved) a reconnection issue I had.
