sharing internet modem over a LAN

[Hiram13]

i have set up a LAN with 3computers and i can share data but the problem now is sharing internet on the network. when i put the server on a normal port on the router its working but when i put to the internet port it cannot access other computers on the network. Am using Dlink wireless router, dlink switch and am on windows7 platform

Himarm13 - you should be able to put your cable coming in from the internet into the DLink router, and then plug other devices into the router normally and have them access the network. Where does the modem come into play? Is the DLink not set up correctly?
