Unfortunately i can't check AP version (i wrote it before, 15.2.4.5)... it was sent back, seller thinking its domain issue (B doesnt work in Canada)....

8.5.110.0 is not a stable issue. I would seriously consider updating the firmware.
Do you know the name of the AP? If you do, post the complete output to the command "show ap join stats detailed <AP NAME>".
If this is a Regulatory Domain issue, it will show up here.

No join information found for AP: 08:4f:a9:fd:a7:b0

Leo Laohoo · ‎02-20-2020

~~That means the AP never contacted the controller.~~

See below.

Reviewed this and this makes sense.

The AP name is incorrect, hence, the message above.

sergo777 · ‎02-24-2020

Solved. Replaced to APs with domain 'A', everything works. Domain 'B' doesnt work in Canada
