The Ethernet {cats UTPsraight-through} cable is missing,but would a standard PC to DSL ethernet  modem cable work?  Now USING Att DSL light  796kps speed  Motorola modem & working great, but my nephew wants to connect to my PC with a 3+old D-link router to try & buy. Is it important to know what his lap-top adaptor or DEVICE inside matches or allows to connect ot the router signal?  Even with the D-link instructions manual there seems to be a difference of opion on how to do it right!  Seems almost simple,but unsure as for the first TIME tried???  UPDATED: 6/7/09;  My Acer AST 180 desktop will be the the main router connection in which my newphews Dell  wireless laptop needs a router internet link connnection as well !  Which connect source receives the RJ45  cable upload?  Hello

Also if u r just trying to connect with a PATCH (straight cable), u should be able to just plug into any connection on the back (#1-4). Just make not to plug into the uplink RJ45 connection.
