You need to network the PCs and the router together. This is done at two different "levels" 1) The physical level by means of installing network cards in the PCs and running CAT5 patch cables so all the PCs are physically connected to the router (the router should have 5 or so ports to connect upto 5 computers and act as a "hub" as well as having a port to connect to your cable modem). 2) At the "Network" level. This is how you configure the PCs to talk to each other using a networking protocol (TCP/IP). This is where most networks fall down. Each PC must have unique IP address, an appropriate subnet mask and a gateway IP address. Fortunately, most router/hubs can act as a DHCP server and distribute this information to the client computers. NTL uses cable technology not ADSL technology so get a router/hub which works with a cable modem. A colleague swears by the Belkin cable/DSL router you can get from PCWorld for �49.99 which is a simple "plug and play" affair. One tip: if you are currently using ethernet (not USB) to connect your PC to the cable modem then switch off the modem for 6 hours prior to connecting it to your router (this allows the modem to "forget" the MAC address of the PC's network card).
