The modem needs to plug into the WAN port on the router first.

If the router has 4 ports just plug the 2 machines into the LAN ports on the router.

You can also add a switch with more LAN ports which you would plug into the routers LAN port using Ethernet cable. :)

Thank you ; now I have 6 PC wire now
