How do I get a Broadcom BCM4312 wireless card to work?
Solution 1
(if the method above doesn't work - resolve "firmware missing" problem) There's no need for ndiswrapper and Windows drivers, because the Linux driver already exists.
If you don't see broadcom wireless device name, uninstall driver, restart computer, install driver and restart again until "firmware missing" message appears with wifi device name under wireless icon after clicking on it (gnome).
If you haven't it, you must install a synaptic package manager from Ubuntu software center
search "bcm" inside synaptic package manager
mark for installation
b43-fwcutter
,firmware-b43-lpphy-installer
,firmware-b43legacy-installer
and apply, no restart needed. Your Wi-Fi led turns on immediately.
Solution 2
I have BCM4312 and 10.10 as well. You might want to try reinstalling the drivers, given that you have already restarted the computer to see if you receive a wireless signal. In a terminal:
sudo aptitude remove bcmwl-kernel-source
to remove the drivers and
sudo aptitude install bcmwl-kernel-source
to install them again. Restart and see if they are enabled/activated in your 'additional drivers' menu.

How to Install Broadcom Wireless card (BCM43XX)I am currently using Ubuntu 10.10 on my laptop , the model of my wireless chip is broadcom BCM4312 802.11b/g LP-PHY .
I tried to activate the driver for the chip by going to
System -> Administration -> Additional Drivers
and activated Broadcom STA wireless driver. But the laptop can't detect any wireless signal still.Do I have to do any additional work to make the chip work ? Or how can I test if there is physical damage to the chip itself?
