EAP772 MLO 6Ghz networks crashing after a while without any log
I've recently noticed that MLO 6Ghz networks crash after a while of running (I don't know the reason, no logs to check what caused it...)
I had MLO networks setup for both 5Ghz and 6Ghz but after an hour or so 6Ghz networks dissapeared (including TP_TX_VAP).
I have multiple EAP772 access points - all of them has the same issue.
Power saving modes are turned off.
AP reboot or 6Ghz band disable&enable fixes it for an hour then we start over again.
Is it already a known bug that's going to be addressed in next firmware release?

Hi @MrNobodySir
To understand the issue better, please give us the following info:
1. what's the hardware and firmware version of the EAP772 units?
2. when did this issue first occer? since first installed? or it was working correctly before?
3. how many 6G clients are there in the network? when the issue happened, did the SSID disappear on all 6G clients?
4. please share some screenshots of the WLAN scan results when the 6G is there and when it disappeared;
5. what kind of controller are you using? what's the firmware version?

2. Since first installed (on stock firmware, same after upgrading to 1.2.0)
3. Number of clients on 6Ghz band: 2
4. I will post screenshots in another post - I need a minute to set everything up
5. No controller yet - standalone mode

Hi @MrNobodySir
When the 6Ghz disappeared, did you check the iwconfig info via ssh access?
Please let us know the result.

@Vincent-TP I'm seeing exactly this same behavior on my EAP772s. 1.2.2 Build 20250327 Rel. 64822. Model v2. The 6ghz network will stop broadcasting (can't connect to it or see it on wifi scans from multiple devices). It restarts after a reboot or will sometimes restart on its own after several minutes.

Hi @Aschnur
Thanks for your feedback.
When the 6Ghz disappeared, please don't reboot it, and go to the following page, run the command iwconfig
Please paste the result for us. Thanks.
After obtaining the info, you may reboot the EAP to recover the 6Ghz.
