Router/Switch?

[Beaverbeliever]

In usual cases, houses have a Modem which takes a phone line or cable line and converts it to Ethernet, which then people use a Brouter. (Bridging-Router) Which usually has several ports on it, and sometimes wireless. A switch is useless unless you have more ports than your Router can support. I would recommend getting a Linksys, Netgear or DLink router with 4-5 ports or so with wireless to use with your Modem.
