Want to share your xDSL Internet connection? You’ll need three devices: A xDSL modem; A router (optionally, wireless); One (or more) machines. Some of the newer modems have router/switch functionality, but we’ll focus on making the modem act as a bridge, a so-called dumb device, between the Wide Area Network (WAN) and your Local Area Network (LAN); which comprises of your router and machine(s). If you already have an existing xDSL service, you will already own a modem and host machine, so all you will need in addition is a router; I recommend the Linksys WRT54G (or WRT54C is OK too), which has served me faithfully.
