Wireless networks are a wonderful thing. However, the freedom and convenience they provide can also come with a healthy dose of frustration and annoyance. Your pain might come in the form of frequent network disconnects, sluggish speed, inability to connect or, if you're really lucky, combinations of all three.
Fortunately, armed with a basic understanding of how wireless networks (also commonly known as wireless LANs or WLANs) work and some simple troubleshooting techniques, you can find, fix or at least minimize many WLAN problems.
In this first article of a series, I'll first provide an explanation of WLAN basics and then move on to describe common wireless problem symptoms and their probable causes. The goal is to help you choose the correct path toward solving the problem you actually have. This is important, since some "fixes" that are applied blindly can often make the actual problem worse!
