I hooked up my old Performa to the Airport Express via ethernet, expecting that it would show up on the network and I could connect to it from my other computers. But it doesn't show up, and if I try to use the Chooser (!!) on the Performa to connect to the newer machines, it gives me an error. I assume the problem is that the wireless connection that the other computers use is not on the same subnet--is that the problem? And is there a way to connect nonetheless?
