Just bought a new airport extreme and after setting up with the information for creating a new wireless network, it obviously needs to restart. But upon restarting, it does not show up in airport utility has that flashing amber light. No matter how many times i rescan it does not show up. I have my desktop computer (a dell with windows xp) connected to the airport extreme with an ethernet cable and the internet works on that computer. But my laptop cannot access the internet and i don't know what to do. I've tried resetting, and that allows me to update it again, but after that the same message comes up.
