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?
