I have a Windows XP machine connected via ethernet cable to a Belkin G wireless ADSL modem router. I've just bought an Airport Extreme card for my iMac G5 (original rev) which is running OSX 10.3.9. Here's the problem: the Airport card cannot see my wireless network, even when the iMac is sitting right next to the router. I think I have the router configured correctly, so is it possible that the card could be a dud? Do Apple occasionally produce faulty cards, or am I being a muppet and missing something obvious here? Any help or suggestions would be seriously welcome as this is the kind of problem which drives you crazy. Cheers Clearly I should also add that the Airport Extreme card shows up with no problems in System Profiler.
