Hi all. I just bought a new iMac 24" yesterday and I'm having some internet issues. I have free internet service in my building. Usually you connect to the signal, and then it brings up a web page where you enter login info to gain access to outside websites. I was using a G4 tower with the original airport card, and didnt have any issues with this. Now with my new iMac, I can connect to the service but the speed lags so much that it's literally slower than 56k dialup. I know nothing is wrong with the building's equipment, as I signed onto it with my laptop and it's just as fast as usual. I know the airport card in the iMac is a newer version than the original one I had in the G4....but shouldnt that make it better? Is there a simple fix to this? I just cant figure this one out. thanks in advance.
