airport dsl connectivity to wan port
adsl over pstn uses RJ11 jack for adsl connection. the guide says to connect ethernet cable (RJ45) for direct connection. when i connect the adsl cable coming from the wall in the wan port it never take an IP because it doesn't fit in the port. should i use a converter from RJ11 TO RJ45 (in case i want to connect the dsl cable directly on airport wan port) or must be connected directly from the wan port to an ethernet port in the dsl router?
