Bug #152
Updated by Daniel Curtis over 10 years ago
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@: <pre> dmesg </pre> * @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: <pre> sudo apt-get install b43-fwcutter firmware-b43-installer </pre> This installs the b43 driver firmware, once this finished I rebooted my computer: <pre> sudo reboot </pre> h2.
