Only reason why I asked is because I had an interesting occurrence with these AirPort cards in two different iBook G3s. I had a Linksys router running DD-WRT and every couple of boots the iBook would connect for 30 seconds and drop and not work after that. I thought it was a bad card but it happened on my other G3 too! Then I realized it was a problem with the router and that unplugging the router caused the card to be completely reliable!
