I’m trying to update my cnPilot E500 APs from cnMaestro (hosted by Cambium).
Current firmware version: 220.127.116.11-r4
Trying to update to 18.104.22.168-r3 or 4.2.1-r12 results in the error message “Firmware verification failed”.
I tried to download the img file for 4.2.1-r12 and apply it manually from the webinterface of the AP, but I get the same error message.
Any advice on what I could do? Maybe I have to chose a different upgrade path to get to the recommended 4.2.1-r12 ?
Some of my APs are wirelessly uplinked to each other, so I want to be sure that the chosen firmware will work, else I will have to climb some ladders
Thanks in advance for your help.
