This question already has an answer here:

I installed Ubuntu 12.10 on my old Compaq/Hp Preario V3000 to replace Windows XP. Every thing works fine except I'm getting no wireless network options in the network drop down menu. I'm using a cable at the moment.

Wirless chipset is:

05:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)
08:08.0 Ethernet controller: Intel Corporation PRO/100 VE Network Connection (rev 02)

I ran rfkill:

0: hp-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no

I also ran iwconfig and got this

lo        no wireless extensions.

eth0      no wireless extensions.

In the additional drivers it says: "Using Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source (proprietary)"

Any help to resolve the problem would be greatly appreciated.

Please hook up the ethernet temporarily and do:

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree
sudo modprobe b43

Is it working now?

Sweet! Nice one chili555. Thanks for your help! – Haoran Dec 13 '12 at 23:14

Try adding b43 to the end of the /etc/modules file. I've heard this can take care of the module waking it up when the computer starts.
