Today I cracked open my son's imac g3 which was in storage for a long times due to it's failing years ago , my son wanted me to throw it away at the time - I quietly stored it instead. Curiosity getting the best of me today, I pulled it from storage in the attic, dusted it off and powered it up. The reassuring Apple boot chime sounded off, but led to a blank screen... trying to insert a CD no go -looks like a CD is stuck in there and drive seems dead. No biggy, cracked the case open to take a look see, and noticed it is outfitted for an airport card, but has no card or the adapter - just the antenna protection sleeve over the antenna wire. OK ! so this baby can go wifi! and I have an extra original card (from my PB G4 that croaked ) all I need is the adapter - $10 on ebay..I can swing that.. But if I recall...the original airport cards 802.11b / 128bits were only WEP capable, not WPA or WPA2 capable.. researching around, all vendors says that card is not compatible with WPA... but some individuals mention when they updated on panther or tiger, the update included airport update which enabled WPA on those cards. Can anyone confirm? much appreciated.
