[QUOTE]\nWell I've failed.\n\nNo matter what I try (and I've tried all suggestions made here) I get this:\nin the Netgear RP614v2's connected devices table, a directly-connected iMac\nshows up, but not the Airport Extreme (in bridge mode). (Yes I power-cycled\nand refreshed the table after each new configuration.)\n\nI've tried connecting the AE to several different ports on the Netgear, first\nconfirmed by plugging in the iMac.\n\nCables are not the issue because if I plug the AE (in non-bridge mode) into\nthe cable modem (using the same or a different cable), it works.\n\nI'm telling mgmt. that paying to have a 2nd cable run to the Airport (costly)\nis the solution. I don't like it but there it is.\n\nI wish I knew enough about the whole IP configuration thing to be able to\npoint to something and say "That is at fault", but it's all a foggy mess (in\nmy head). I know that with experience comes competence, but isn't there a\ngood starting point such as a web-seminar or e-book that can cover the basics\nand more?\n\nThanks for all who contributed to the discussion.\n\nDave\n[/QUOTE]\n\nIf you haven't managed to sort this yet, then there is possibly another\nway without you having to lay another cable.\n\nThis is assuming the connection between the Comcast modem and the\nAirPort is 10/100 and is not using PoE\n\nSimply use a CAT5 Economiser like this both ends of the cable\n[URL]http://www.ebay.co.uk/itm/290335345691[/URL]\n\nConnect the A port one end to the Comcast Modem, and the other A port\nthe other end to the AirPort\n\nconnect the LAN Ethernet side of the Airpoint to the B port, and a\nsimple network switch to the B side near the Comcast modem.\n\nIf you like, you can use the Netgear as a switch by just disabling the\nDHCP server on it, and connecting to one of the LAN ports, just ignore\nthe WAN port on this.
