I have tried for years (since 2019) to apply firmware updates to the 2 R510 APs on my Lennar installed network. Thought it might be related to the Switch (ICX7150) firmware being outdated, so I updated that to the current recommended release. Still not able to upgrade the R510s. Same behavior and error as in the past. Using Unleashed, I supply the local firmware upgrade file (R510_200.15.6.12.304.bl7). The app confirms the file and I hit the Upgrade button. It slowly uploads to both the Master and Member APs at the same time/rate. Right after hitting 99% the app reports "Fail: deploy timeout" I have rebooted the APs and rebuilt the Unleased network multiple times. I have power cycled the APs. Any help is appreciated!
