Hi there, I have an existing IAP-305 cluster of 12 APs. All APs are running firmware 8.3.0.2-8.3.0.2_66308 and are managed by Airwave. Recently 3 of them went offline and I don't know why. I went onsite to troubleshoot with the console cable and they were all sitting at the apboot> prompt. A reboot of the AP causes it to boot to apboot> and go no further. I did a factory reset on the 3 APs and they all re-joined the cluster, but if I reboot any of the 3 APs, they boot back to the apboot> prompt and go no further. The remaining 9 APs in the cluster can be rebooted and come up fine.
I must say that I'm at a bit of a loss troubleshooting this issue so I came here for help. Any guidance someone could provide would be greatly appreciated.
Thank you.
Chris
