No Wireless connectivity after installing Ubuntu 12.10 on Windows 8

Question

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

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.
