Once more I turn to my eMac confreres for help. This time it's my Airport Express. After not using it for a while I tried to bring it back on line -- no change in ISP -- and got the flashing amber light. After several tries at bringing it back I did a hard reset -- use paperclip to hold reset button down, plug into AC while still holding down reset button, get four green flashes -- and then a re-install to create a new network. It all went tickety-boo -- according to Airport Express the new network is up, running and connected to the Interntet -- but the amber light keeps flashing and I can't get out on the Web.

I haven't got a clue. Anyone?

Maybe this will help.

The fix turned out to be the simplest possible, and it's one we all know: unplug the modem and the computer from the A/C power, wait 30 seconds, and reboot. Worked immediately. Thanks for your suggestions.
