My Linksys WRT54G2 Wireless G Router is excellent.  I brought a Linksys G USB Adapter for my other desktop and with the router I am able to surf the web without worrying about my teenager having a fit over me using the computer.  We both can be online at the same time.  The router has excellent range.  I get 5 bars easily.  Very easy to setup.  Excellent tech support, 24 hours a day.  The price I paid was under $45.00
