hey all..my wife and i both just upgraded from our old powerbook g4's. We now have new macbook pros that are running Leopard. The issue we are having is staying connected to the internet. I am not sure if this is our network subscription with ATT that has the issue, or if we need to configure something else on our laptops. The old powerbooks are still connect 24/7 , but the new computers are loosing connection every 10 or 15 minutes....anything we should be looking for??
