Travel
With a wireless network, you are free to roam untethered anywhere within a few hundred feet of the base station and still enjoy high speed access to the Internet.

All that's required is a wireless router and the appropriate network adapter and you can be surfing from any room in your house.

Shopping Tips
Pay a few dollars more for the 802.11g protocol (referred to as "G") because it is 5 times faster than the "B" models. You will need a router to connect to your DSL/cable modem and an interface card to attach to each PC.

Prices have dropped over the last year. You can now pick up a "G" router for as little as $50.
