Awhile ago I picked up a few 400Mhz G3 Blueberry iMacs. Excellent deal on the machines and they work pretty good with the copies of 10.2 that came with them. I have a couple of belkin USB wireless adapters but from my research online there are no Macintosh drivers for for my belkin adapters. Searching around on ebay I have discovered various different adapters that claim they work on Macintosh, but obviously I am weary to spend my money on adapters that may not actually work with my system. I have found airport cards online, but excuse my ignorance, will they work with my Cisco router or would i need one of the airport base stations? Thanks for any suggestions, past experience, and ideas.
