This is my situation; I have a hard wire connection from my wall phone/DSL outlet to a Westell model C90 DSL router/modem. Since this allows for only one single hard wire connection to one desk top (I have 2 desk tops plus 1 laptop), I hard wired the Westell modem to a D-Link router model DI-604, which should allow for the 3 computers to be connected to the internet simultaneously. However, with the wiring as described, only one computer can be connected to the internet at any time. What am I doing wrong?

Also the same problem occurs when we substitute the D-Link Router with a Netgear Wireless Router, WNR2000. So that would be Outlet > DSL Modem > Netgear Router > 2 desktops and a laptop. In that case the network cable is run from the Ethernet port of the DSL Modem to one of the Ethernet ports of the Netgear router, not the port that says "Internet". When I do that, the computers don't connect. Also the same problem occurs when we substitute the D-Link Router with a Netgear Wireless Router, WNR2000.

So your connection is: Phone outlet -> DSL Modem -> D-Link Router -> 2 desktops Is that right? what input from the D-Link are you connecting the DSL Modem to?
