Why is the radio 1 transmitting power with 0 dBm, even when the radio 1 is on and a channel is selected. (AP3825i-1)

We have a V2110 Medium running with Software: 10.41.10.0014, after a few hours a lot of 3825i-1 (30 out of 80) starting transmitting power with 0 dBm!. And the clients can't see the emitted SSID anymore. We use all channels on Radio 1 (5GHz) and the selection is auto. You have to turn Radio 1 off and on to get back the power. The country code is correct and the license is valid. That's all a little bit miserable. Any suggestion how to solve the problem? Green IT? šŸ™‚

Here are my results from the last few days:
a) I factory reset an AP 3825i and synced it again
b) I changed the country code of another AP 3825i from Germany to Austria.

24 hours later the AP from a) and b) were still transmitting with more than 0 dBm.

Both solutions seem to work. So I had to facory reset about 26 APs, or take a another "Country Code".
I was not realy amused about both slolutions. Should I take cholera or black death?

I decided to have a look for a newer version and I found version 10.41.11.0009.
I installed the version on Saturday 11/17/2018 at 5pm.
And now 36 hours later still all APs are tranmitting power with more than 0 dBm.

Some background information: One week ago we made the version upgrade from 09.21.18.0009 to 10.31.10.0001 to 10.41.10.0014. Now with version 10.41.11.0009 everything seems to be fine.

Not clear what realy caused the problem, maybe the upgrade form 09.21 to 10.31. Now that's something for the experts. šŸ™‚

Thank your for your suggestion,

but we don't have these feature on.

We had a similar problem with a deployment of AP3825e's. The APs would freeze up and stop transmitting. The power would drop to zero and the SSID would disappear. A reboot would bring them back for awhile but then they would freeze up again.

GTAC recommended to remove Radio Management 11k support from the VNSs that were working on the APs.
We did this and the problem did not recur.

After the reboot it takes about 10 to 12 hours until it happens again. Maybe because there is no MU anymore.

To get the ap.log is not a problem, but to understand it and to know for what I'm looking is a Little bit tough.

a) I factory reset an AP 3825i and synced it again

b) I changed the country code of another AP 3825i to Austria

I'm looking forward for the results.
