A wireless router and an adapter (for your client PC). You can add repeaters too if you feel creative or need the extra coverage.<br>

Each client PC needs an adapter, except of course for the one that will be hooked up to the router (once the router is set up it does not need to be connected to a PC, just the modem). There are other brands of course, so it's up to you to decide which one is the best. In my opinion the best routers are from Netgear, Belkin, Trendnet, Buffalo, and Airlink while Linksys makes some of the best and most robust adapters. You may want to make all your devices from a single brand since some offer "special" features when used with their own devices; this is not a necessary thing but sometimes you may run into compatibility issues when mixing and matching from different vendors.
