ok I better disable 36S and 100S then as we are next to marine industries so I guess radar is often used.

The two 160MHz channels are 36S and 100S
Dynamic Frequency Selection (DFS), a mandate for radio systems operating in the 5 GHz band to identify and avoid interference with radar systems. So When an 802.11 radio detects radar, it vacates its channel and switches to another channel but should wait for period of 10min (I think) of inactivity

Hello Carson,
I am not technical, so which are the 160 MHz channels?
And what is DFS channel?

That or remove the two 160 MHz channels from the allowed list. If you disable 160 MHz in the ARM settings then the 6 GHz will also go to 80 MHz...which might also be a good thing but at least 6 GHz isn't going to suffer from DFS channel restrictions.

Hello Carson,
thanks for looking at the logs, so this setting is at Config->RF->ARM->Access Point Control->160MHz support change to NONE?

Because you are running 160 MHz channels on the 5 GHz, there are only two options and both include DFS channels. You're getting radar hits and the radio has to stop operations. Move to 80 MHz or even 40 MHz for 5 GHz.

Thanks for taking time to look at the logs.
the configuration-> access points -> radios is already set as access.
configuration->RF->Radios, Background spectrum monitoring was turned on, now I have turned it off to see if it was an issue.

it looks like the 5GHz radio on that AP is set to ap-monitor mode.

see fi you can change that by going to the configuration-> access points -> then select that AP

I'll have a look when i get a chance but it is better to reach out to our TAC for resolution.

So it happened again, I did a dump of the logs attached. Disable Background spectrum monitoring on 5Ghz radio and reboot the AP.
Lets see what happens.

Hello,
I check and Background spectrum monitoring is enabled for all my radio profiles.
Maybe it hangs when doing monitoring? Should I turn it off?

this is from AP-655 installation guide, solid amber is that radio is in monitor mode.

Hello Carson,
I don't see anything in the GUI indicating an error, only the 5Ghz led is solid orange on the AP. So far no issues till now after the reboot, hope it does not happen again.

Email notifications would be a function of a monitoring service like AirWave or Central. If the IAP is actually in an error state, then yes, something should be showing in the GUI or discoverable through the CLI.

Sure will try to remember to do that. BTW do you know of any way to send a notification email if the AP gets into any errors/faults

if it happens again, see if you can get the output of "show tech-support" before you reboot it.

Hello Carson/Ariyap,
thanks for replying,
Build Time2024-03-03 18:36:58 UTC (build 89362) by jenkins
Version8.12.0.0 SSR
I have each APs connected to 2 POE Class 4 ports, but they draw less than 20W, 17 to 19W each.
ipm is enabled in the config.
The APs were working without issues with 2.4 (Guess) and 5+6Ghz (Employee) ssids enabled. It was running well for 6 months before this, so far only happened 2 times.
I would think there would be some way to send a notification email of any errors/faults, or the Instant GUI should indicate an issue.

What version of software? If this is powered by PoE, is this 802.3at or 802.3bt? Is IPM enabled?
I would recommend you open a case with TAC.
Emails directly from the IAP aren't an option.

Hello,
I have 3 655 APs setup using instant and have encountered 2 times the 5G radio turned off by itself (LED solid orange) on 2 different APs.
I only got to know it when the users start complaining unable to connect to the wireless network (unable to see the SSID).
Logining into the GUI does not give me any notifications of the problem, it is only when I physically check the AP that I notice the orange LED.
Restarting the AP solved the issue.
So anyone knows how do I check what caused the problem in the first place and why the GUI does not show that there is a problem?
And is there any way to enable notifications maybe by emails of this kind of issues?
