Repair Hardware Failure After Ubuntu Upgrade

Some of you might found a hardware failure after had Ubuntu upgrade. In Matthew Helmke case, his network wireless card didn’t work after he had upgrade his Ubuntu from 11.04 to 11.10. Although this post discusses the network card, but I think to fix the other hardware is not much different.

Lets starts the lesson, kid :)
Knowing your hardware

Before we could do anything, we needed to learn a bit about our hardware; in this case the model of wireless network card we had. This is easily accomplished using a few commands in the terminal.

We start with the nm-tool command, which is a utility that provides information about NetworkManager, device, and wireless networks.
