Product Description Share Your High-Speed Internet Connection Throughout Your Home or Office Think of the EtherFast Cable/DSL Router with 8-Port Switch as a kind of splitter for your Internet connection. Just connect your DSL or Cable Modem to the Router, and all the computers in your home or office can share the Internet -- all at the same time. The built-in 8-port switch lets you attach eight local PCs directly, or daisy-chain out to more hubs and switches as your network grows. Once your computers are connected to the Internet through the Router, they can communicate with each other too, sharing resources and files. All your computers can print on a shared printer connected anywhere in the building. And you can share all kinds of files between computers -- music, digital pictures, and other documents. Keep all your digital music on one computer, and listen to it anywhere in the house. Organize all of your digital pictures in one place, to simplify finding the ones you want, and ease backup to CD-R. Play head-to-head computer games within the household, or against Internet opponents.
