Router Basics
A wireless router provides access to the Internet by way of radio waves, making it possible for laptop computers and a variety of other devices to connect wirelessly. It is a very commonly used device in modern homes and places of business. They are relatively easy to set up, and once in place, they require little direct user interaction.

Choosing a Wireless Router
-
1
Consider the size of the area to which you need to provide access. An inexpensive, run of the mill router has enough strength to provide coverage to a two-bedroom apartment, or even a small house. If you wish to cover a larger area, then you will need a more powerful router with enhanced range.
-
2
Consider the types of devices you wish to use. This will dictate the type of router you need. Some devices use Wireless G protocol, while others use Wireless B protocol. Generally most routers that can handle Wireless G, can also handle Wireless B. This does not work the other way around.

Consider the number of hardwired connections you need. Some of the nicer models serve as a hub of sorts, with several LAN ports, making it possible to connect several devices directly. Though not everyone needs this, for some it can be a handy option.
