Comment 10 for bug 1113779

Ubuntu 13.10 and laptop HP Compaq nx6310 (
$ lspci -vvnn | grep 14e4
02:0e.0 Ethernet controller [0200]: Broadcom Corporation BCM4401-B0 100Base-TX [14e4:170c] (rev 02)
08:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01)
)
I use:

sudo apt-get remove bcmwl-kernel-source
sudo apt-get install firmware-b43-installer

Of cause "install" needs internet connection, I use cheap usb-wifi-mini-stick (RTL8188CUS 802.11n WLAN Adapter).
