You will need a modem as well as a router - sometimes you can get a combined router/modem. You need a cable from the telephone to the modem, a second to the router and one from the router to each of the PCs. Required software will come with the equipment, as will most if not all cables. In addition, you will need a slitter on each telephone point on which you have a telephone. Some of the equipment may be offered by an ISP, but this will be limierd to one splitter, a modem and the cables for a single PC. SO far a ISPs are concerned, you pay your money and take your choice. I pay more for Claranet, but their service and technical support is excellent. You can pay 50% less and you get what comes. For a slightly less biased view click here.
