Description

I encountered an error after installing Lubuntu 13.04 on my Dell Latitude D410, in which I could not see or connect to any wireless networks. I began troubleshooting by checking dmesg:

dmesg

...
[ 18.183959] Broadcom 43xx driver loaded [ Features: PNL, Firmware-ID: FW13 ]
[ 19.288135] b43-phy0 ERROR: Firmware file "b43/ucode5.fw" not found
[ 19.288142] b43-phy0 ERROR: Firmware file "b43-open/ucode5.fw" not found
...

The problem was that I did not have the proprietary Broadcom driver installed. To fix this I ran:

sudo apt-get install b43-fwcutter firmware-b43-installer

This installs the b43 driver firmware, once this finished I rebooted my computer:
sudo reboot
