I'm trying to adopt EAP225-outdoor to my existing controller managed EAP650 network but it won't adopt wirelessly. I can get it to adopt wired but when ethernet is disconnected it gets isolated.

Error message that I get is “Failed to link to uplink AP.”

I've tried to connect to three different Root-AP with different channels but no luck there.

Controller is software based with version 5.14.20.9
