Jim, Are you talking about the PC Card version or the PCI card version? Does it work in OS9? STeve << As for 802.11 cards. I dropped my Airport 11b card in my G4/500 for a Sonnet 802.11g Aria Extreme. It works flawlessly (actually better than the airport card - no interference to the USB ports when transferring data). It is also pretty good and fast. From my LAN, I can transfer 300Mb in about 3 minutes (v. about 12-13 for airport card). >>
