OK. I have a iMac and a MBP connected to the new AirPort Extreme model. My sister's laptop cannot connect to it. We have tried many many many methods, and all of them have been unsuccessful. NOW, I still have the OLD AirPort UFO model. I tried to connect it to my MBP, but I really can't run it because it is out of date. I can't install anything from the AirPort disk because it is too old. Here is the question: Can I still hook up the old AirPort? Is there some way that she can use that for the internet?
