Going crazy over here... I use airport extreme to connect to cable wireless modem for internet and use airport express to connect my printer to my existing wireless network. All was fine until I changed the channel on my airport extreme to lessen interference with my neighbor's router. Now extreme is fine and internet is faster, but ever since i have not been able to get my airport utility to recognize airport express, which flashes amber. I tried a soft reset, hard reset, restarting macbook, but no dice. Any suggestions?
