Cable modem directly to switch. mistake? Tags: Routers Switch Modem Cable Networking Last response: January 6, 2010 1:55 PM in Networking Share roboboy January 5, 2010 10:30:04 PM I am a novice. Did I make a purchase mistake? old set up: cable modem to linksys router (rt41bu) then to pc's #1 and #2 linksys router died... so i bought an 8-port "desktop switch". new attempted setup: cable modem to d-link desktop switch(DGS-2208) then to pc's #1 and #2 now only one pc is connecting. I've now been told that with a cable modem, that I must have a router for multiple pc's to connect. Is this true? Thanks.

Get the answer itadakimasu January 6, 2010 1:55:01 PM A switch won't work... you need a router, or a layer 3 switch that is capable of NAT and dhcp. Routers use NAT, which allows you to use private ip addresses on your internal network, and just 1 public IP address. ISP's only give you one IP address unless you pay for extras. You'll need to pick up another router. Can't find your answer ? Ask !
