Whats the point in snapping at hadou??
You go into your wireless options MyNetworkPlaces>View Network Connections you should have a computer labeled Wireless connection, right click>properties then i think its the second tab at the top, add a new wireless network and set the ssid name to linksys, click enter then if youve set the router, you should connect.
The instructions should tell you how to do it. Ive been able to do it since i was 10 *self taught* (just to rub it in)
