I have the following wireless hardware on a Compaq evo N600c laptop running lubuntu latest.
ciaran@compaq:~$ lspci -vvnn | grep 14e4 03:00.0 Network controller : Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller [14e4:4320] (rev 03)
Following the instructions from here :
I opted for the legacy firmware installer, following instructions for internet install to the letter (with no errors). i.e. I successfully installed
sudo apt-get install firmware-b43legacy-installer
In the nm-applet I now get
Wireless networks device not ready (firmware missing)
I open up Additional Drivers, but the list is empty. I have commented out this line in /etc/modprobe.d/blacklist.conf
Contents of firmware dir:
