If u already have an ADSL connection then all U need a wireless router for the ADSL modem to plug into + a wireless card for your computer . . . . Dlink, Netgear & Netcomm are reasonably priced with Dlink & Netgear having 802.11g+ (104Mbps) models
If no ADSL available then look for a 56K wireless modem/router, to plug into your existing phone line
