After upgrade to software 21.0 this unit rebooted into a blank config, and “Maximum Throughput : 4 Mbps Aggregate”. The event log reports “Feature Key not found.”.
Log from cnMaestro: “Failed Upgrade Timedout: Device is taking longer than 5 minutes, Last known status was: Rebooting device”
So far we have upgraded 60 devices (5 APs) and seen this issue on one unit so far. Is there any way to resolve this?
