Just recieved my 15 inch Powerbook, and everything was setup. But registration didn't go through so I decided it was the same thing that happened to my sister's iBook, it didn't go through the first time. So.. i go to the other room and I decide to try out Safari. I can't connect to the internet! Airport is at one less than full strength, which should be enough to get a signal. What's wrong? router is a DI-614.
