My old Airport Extreme cannot connect to the new Airport Extreme (Base) after I upgraded to the 7.7.1. firmware.
The old extreme was working as part of the extended network when the New Extreme Base it had the 7.7. version, now amber just blinks away.
I tried hooking up an Airport Express and have the same problem.
Any pointers?
AirPort Extreme 802.11n (5th Gen), Mac OS X (10.6.8)
