Hi,
I am trying to connect xbox live to the dsl without disconnecting my modem everytime. Also, when I connect my two computers through the linksys switch, only one can be connected to the internet at a time. I thought that it might be my modem, but my friend has the same one (sbcglobal, speedstream 5100) and he has a successfully networked home and can use the internet on all of his computers similtanously. What could be my problem? Do i have to buy a router? I would think that the switch should do.
thanks.

Good catch by and good question . The short path is to put a NAT-capable router between your DSL modem and the rest of the house, but the practical details matter when you add an Xbox and multiple PCs. Below are concrete setup steps and troubleshooting tips that pick up where the replies stopped.

  1. Hardware/layout: connect DSL modem -> router WAN port -> router LAN port -> Linksys switch -> PCs/Xbox. The switch stays on the LAN side to expand ports.
  2. Router settings: set the WAN type to whatever your ISP uses (PPPoE if SBCGlobal required a username/password), enable the router DHCP server, and update the router firmware and admin password. Power-cycle the modem after you plug the router in so the modem hands the public session to the router.
  3. Xbox specifics: enable UPnP on the router if available (easiest fix). If not, reserve a static LAN IP for the Xbox and forward the Xbox Live ports (commonly UDP/TCP 3074 plus UDP 88 and TCP 80/UDP 53) or place the Xbox temporarily in the router DMZ if NAT remains strict.
  4. Double-NAT check: if the router WAN address is in a private range (10.x.x.x, 172.16-31.x.x, 192.168.x.x) you have two devices doing NAT. Either set the SpeedStream to bridge mode (or disable its DHCP) or let the modem act as bridge and have the router manage PPPoE.

If you prefer not to buy hardware, a PC running Windows Internet Connection Sharing or a Linux box can act as a gateway but must remain powered on. For persistent Xbox NAT problems, reserve the Xbox IP and try port forwarding or DMZ rather than leaving UPnP off.

You specificly need a Cable / DSL "router"/

Ther eis a large difference between a switch and one of these cable dsl routers.

A switch will just share a connection and most ISP's only provide a single IP address, which is why You cannot have more than one system online at a time.

Ahh, that is what i suspected, but I didn't know for sure. Thanks for clarifying that for me.
