My ethernet port on my iMac DVSE 500 (Summer 2000) was fried in a lightning strike that took out the DSL modem and the Linksys router in one shot. The repair place says they'd probably have to replace the logic board for $325. This isn't a very acceptable solution to me. I want to get around it by using an AirPort card and a new Linksys wireless router. My only question is, is the AirPort's interface completely separate from the Ethernet and thus wouldn't have been harmed by the lightning?

Any info would be appreciated. Thanks!
