I have a Linksys Wireless-G Notebook Card Model # WPC54G (that is not compatible with MAC OSX. Any PC users looking for a wireless card let me know. I am asking $40.00 for the card. It is brand new in the box with all software and manuals.

Also have a G3 Imac 400 DVD, details can be seen here:

Feel free to ask any questions on either item. :D

If you are still interested in keeping the card, check this out:

You can download the Apple Airport Extreme updater from Apple.

Of course, if this is a rev 2 card, then you might be out of luck since Linksys had changed chipsets from the first to the second revision.

Well thank you very much for the information. I have a newer PB that has the built in airport card, and also the extreme base station. This was just stuff my old room mate left behind. If anyone with a Mac is interested in the card, I will point them to the link you gave me. :D
