Hi, The AirPort Exterme card on my G5 (single 1.8GHz OS 10.3.9) has not been able to get any signal from the router (probably) since the power outage a couple of months ago, though my G5 recognizes the card. The firmware for the AirPort Exterme card is 404.2 (184.108.40.206.p16). (The updates on the apple site seem to be only for the base station.) The wireless router D-Link DI-624 is working properly my MacBook gets a signal from it normally. I would appreciate it very much if someone could help me. Thanks.
