Hello all. I'm after some advice please. I was given an imac the other day, which was very lovely. However, I can't use the Internet on it. It can find the signal from my wireless box, but won't connect to it (although my iPhone connects just fine). The iMac appears to want to find an airport base station, which I don't have, and don't especially want to buy. I'm wondering if the iMac has previously had an airport card installed. If so can I remove this (and how?) and would this solve the problem? Or any other ideas very welcome!!! Many thanks julia
