I recently installed Lubuntu 14.04 on my parents' old laptop, and I've been having a super difficult time getting the Broadcom card up and running. I've been following this thread: Installing Broadcom Wireless Drivers
...but I'm still stuck.
lspci -vnn | grep Network showed:
06:05.0 Network controller : Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller [14e4:4320] (rev 02)
lo no wireless extensions. eth0 no wireless extensions.
b43-fwcutter and also the
linux-firmware-nonfree package. At boot, I keep getting a b43-phy0 error, so I tried
sudo rmmod b43, and I got:
rmmod: ERROR: Module b43 is not currently loaded
I also tried:
dmesg | grep b43 [ 17.318405] b43legacy-phy0: Broadcom 4306 WLAN found (core revision 4) [ 17.384870] b43legacy-phy0: Loading firmware b43legacy/ucode4.fw [ 18.046777] b43legacy ssb0:0: Direct firmware load failed with error -2 [ 18.046785] b43legacy ssb0:0: Falling back to user helper [ 18.047858] b43legacy-phy0 ERROR: Firmware file "b43legacy/ucode4.fw" not found or load failed. [ 18.047965] b43legacy-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware (version 3).
I went to url it told me to, but it didn't tell me to do anything I haven't already tried.
Any help and/or suggestions would be greatly appreciated!
