<p>Yes, it's pretty simple. Each piece of wireless equiptment that has a network adapter has a MAC address (not to be confused with any of Apple's Mac products) that is printed on the box, on a sticker, or in the hardware information on your PC. It's a 12-digit hexidecimal string of numbers that looks something like "00-B0-D0-86-BB-F7".</p>
<p>Think of the wireless router as your house. Each router has a user interface which can be accessed via something called the default IP address. Think of this like the front door to your house. Each MAC address is subordinate to this one, like doors to the bedrooms in your house. By typing in the default IP (front door) of your network, you can access the settings of your router and control the traffic that uses the front door in either direction. I'm sure IT pros are screaming at my oversimplification of a network; just back away from the keyboard and let it go.</p>
<p>Now... Cox, Comast, TimeWarner, and others contracted for routers that come with their own software. This is the gate at the entrance to their community, if you will. The software will prevent most things from taking over your network, but will also prevent you from doing other things with your network that most of us want to do... like MAC address security, for example. They do it to prevent you from running home-based servers and sucking up all the bandwidth. I highly recommend you get a regular cable modem and return any router they provided for you.</p>
<p>I did network set-up support for Nintendo when they introduced the Wii. I am confident that you can set it up with a brief review of the manual. The best thing about wireless networks is the freedom that wireless provides. Our router sits on the third floor, but the wireless allows my wife to work from her garden desk and enjoy the smell of fresh roses in the summertime, allows us to keep the Wii updated on the second floor, and allows me to surf the web on the first floor. With 5 computers in the house, running cables all over would really suck, as would being restricted in our choice of location of those boxes. I highly recommend getting a wireless router.</p>
