Hi! I recently switched from DSL to Cable internet. After I switched, the green light on the AirPort CONSTANTLY flashes -- as if there's constant activity. The AirPort was set to "Flash on Activity" when it was attached to the previous DSL modem and it only flashed when there was obvious activity. Now it flashes constantly green -- even when all devices are turned off. I have ruled out anyone lurking on my wifi. Even after resetting the wireless password, the green light again immediately starts flashing constantly. I've searched and searched the Internets for anyone with a similar issue, but have yet to find one. Should I be concerned? Should I just let it flash? I like to see when there's activity on the AirPort, but now watching it flash all the time just makes me paranoid. P.S. It also does the same thing when hooked up to an early 2008 Time Capsule. Thoughts?
