UAP v2 units disconnected after controller upgrade.

Hi, Can you please advise me?
I have a Ubiquiti Unifi AP v2, configured it, and everything worked. I upgraded Unifi Controler from 5.4.16 to 5.4.19. After starting, all 5 units are written to be updated. That's what I did and it ended. I uploaded the new firmware and the units are now constantly being adopted, then disconnected, and then again. I uninstall the new version of the controller and returned it back to 5.4.16. Unfortunately no change. I tried downgrade firmware UAP v2 and unfortunately without success. Is there anything else to do with that?

 

Thank you for your help

Hello @Milan574,

 

Welcome to the community!

 

What firmware did the UAP upgrade from/to?

Have you tried to reset 1 UAP to see if it makes any difference?

Glenn R.

Re: UAP v2 units disconnected after controller upgrade.

Yes, reset, but a new FW is already loaded on all units. I don't know what FW is best for UAP v2 and control 5.4.16. I don't know what was the original FW.

Thanks for the help

Hello @Milan574,

 

Did the factory reset of the UAP help at all?

Can you SSH into the UAP?

Reset button pressed for 15 seconds, it didn't help. I wasn't there over SSh.

Hello @Milan574,

 

What is the LED color of the UAP?

You can't SSH into the UAP?

Re: UAP v2 units disconnected after controller upgrade.

the color is still yellow - not blinking. I haven't used SSH yet. I have UAP at home and I'll be there in the afternoon.

Hello @Milan574,

 

Forget that UAP in the controller, then SSH into the UAP and set-inform to the controller and adopt it.

set-inform http://ip.of.the.controller:8080/inform
