Wireless Troubleshooting Guide

Wireless has long been the white whale of F/OSS operating systems. In recent years, however, open source drivers for a variety of wireless devices have greatly improved. Frequently, it'll "just work". Still, we'll sometimes have to get our hands dirty in order to get things working. This article will cover some general practices on configuring and troubleshooting wireless under Linux, and then go into more specific examples and known good solutions.

For reference, this will all be conducted under Xubunut 12.04, although much of the material should tranfer to other versions of Linux.
