Comment 22 for bug 289845

i JUST WENT THROUGH THIS.
OPTION 1
 Load kubuntu-desktop in synaptic. USE PATCH CABLE NETWORK 500 MEGS of files. You can now use additional drivers in a graphical environment.
Option 2
Attempt to install your wifi driver. If it install your done. If it say's BLACKLISTED or check log file /var/log/jockey.log OPEN A TERMINAL and run "sudo gedit /var/log/jockey.log" if it has a series of errors scroll to bottom and see if it lists drivers as BLACKLIST.
If so, run "sudo ls /etc/modprobe.d/" and it will return something like
alsa-base.conf blacklist.conf blacklist-oss.conf blacklist-ath_pci.conf
blacklist-firewire.conf blacklist-rare-network.conf dkms.conf
blacklist-bcm43.conf blacklist-framebuffer.conf blacklist-watchdog.conf iwlwifi.conf
blacklist-modem.conf broadcom-sta-common.conf vmwgfx-fbdev.conf
figure out witch ones have your drivers in it. I used:
blacklist-bcm43.conf
broadcom-sta-common.conf
blacklist.conf
using the command "sudo gedit /etc/modprobe.d/blacklist-bcm43.conf" unblacklist the driver using (# driver ). The comments at the top of the file is guide for commenting. Do this for each PERTINENT file. Reboot.
YOU THINK IT WOULD HAVE WORKED BUT NOOOOO! using the command "sudo gedit /etc/modprobe.d/blacklist-bcm43.conf" FOR each PERTINENT file and comment out every blacklisted driver from your manufacturer.
