The ENTNER.NETwork

With the new version of Ubuntu, 11.10, the wireless device of my daughters notebook, of course, stopped working again. As with every update.

Here the dmesg output:

[  819.032504] b43-phy0 ERROR: Firmware file "b43/ucode15.fw" not found
[  819.032510] b43-phy0 ERROR: Firmware file "b43-open/ucode15.fw" not found 
[  819.032516] b43-phy0 ERROR: You must go to http://wireless.kernel.org/
en/users/Drivers/b43#devicefirmware and download the correct firmware for
this driver version. Please carefully read all instructions on this website.

lspci:

~$ lspci -vnn |grep 14e4
04:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY 
[14e4:4315] (rev 01) Subsystem: Broadcom Corporation Device [14e4:04b5]

The following command, using a network cable, helped this time:

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