hello friends
I have a 9800 physical controller with version 17.9.3, the AP 3702 is linked to an airos controller in version 8.5, when I try to link the AP 3702 to the 9800 controller, I see it but it stays in the downloading state, I check the image The AP firmware never updates to version 15.3(3)jpn2,
I saw in some publication that you must enter romon to resolve this issue, but I do not have that possibility because the AP is in a remote location and I only have access via ssh.
What ways are there to solve this problem without having to enter romon?
