PTP 4600 error link Reason: 49 (INVALID SECURITY KEY)

The EPMP 4600 worked stably for two weeks, but now every 12-14 hours was disconnected for 2 minutes and reconnected.

Had the same thing when connecting the SM’s. Ended up having to put the AP to open and SM to open. I know that the passkey was correct, I literally stared at it for 30 minutes comparing the two on the bench. Thought it was a fluke, deployed it with a couple different SM’s and same thing happened across 2 different APs. Our tech encountered the same thing. Only thing ive found to get around it is to set it to open. Not the safest thing, but in my scenario i literally had no choice

Cambium, what can you say about it?

Hi, Maxim

Would you mind creating a ticket, that we could study your particular case in details?
