No Wireless connectivity after installing Ubuntu 12.10 on Windows 8

I am new to Ubuntu/Linux.

I have installed the Ubuntu 12.10 version on Windows 8. After installation, there is no wireless connectivity. I have searched the forums and tried things that have worked for others. But, every way seems to be a dead-end to me.

I ran the command lspci -nn | grep 0280 and here is the details I get.

03:00.0 Network controller [0280]: Broadcom Corporation BCM43228 802.11a/b/g/n [14e4:4359]

The command sudo iwconfig gives the below output.

eth0      no wireless extensions.
lo        no wireless extensions.

I downloaded the bcmwl-kernel-source from Ubuntu Software Center and installed, but there is no change.

I am at a loss, being new to the OS.

Any help from you will be much appreciated. Kindly let me know if I missed to provide any information.

Solution 1:

If you have several drivers installed, the Linux kernel will pick the right one automatically. Regardless of the driver, though, your chip might need firmware to work. Find firmware-b43-installer from the Software Center.
