Hello. I have two macs. One is a bluberry G3 imac that can't use an airport card. The other is a lampshade g4 imac that does not have an airport card installed yet. I need to have both these computers using the interent but I don't know how to do that. First off I know I can buy the base station with one wired port for 200 dollars, and then a used airport card off ebay for 150. It seems like a ton of money. Is there any other way? I am currently used a cable modem, bothe computers are using 10. something.
