I find this helpful when my home internet and wifi devices get wonky. The preferred sequence is:
- Power off all devices, which would include the cable "modem", and three separate airports.
Power on the cable modem, wait 1 minute
Power on Airport 1, wait 1 minute
Power on Airport 2, wait 1 minute
Power on Airport 3, wait 1 minute
I'm sure Matt or Jay will move this to a more appropriate location if action groups wouldn't work for me.
