Hi Guys,

we have 2 EAP615-Wall(EU) and 2 EAP620 HD(EU) AP in a small office / flat.

The EAP620 HDs are working well, without any problems or failures. But the 2 EAP615-Wall devices are "doing" very interesting things...

From the log tonight (GYAP02 and GYAP04 are EAP615-Wall(EU) devices):

[Failed]GREE-AIRCOND01 failed to connected to GYAP02 with SSID "GYSMH_2G" on channel 48 because the Association times out.(1 time in a minute) Sep 30, 2022 05:21:22  

So: "failed to connected to GYAP02 with SSID "GYSMH_2G" on channel 48" --> Yes because this SSID works only on 2G, channel can be only 11!

5G is unavailable on SSID "GYSMH_2G".

And the other problem:

[Failed]GYMOBILE01 failed to connected to GYAP04 with SSID "GYWIFI" on channel 44 because the Association times out.(2 times in a minute) Sep 30, 2022 06:49:59    
[Failed]GYMOBILE01 failed to connected to GYAP04 with SSID "GYWIFI" on channel 44 because the Association times out.(4 times in a minute) Sep 30, 2022 06:47:59    
[Failed]GYMOBILE01 failed to connected to GYAP04 with SSID "GYWIFI" on channel 44 because the Association times out.(4 times in a minute) Sep 30, 2022 06:45:29    
[Failed]GYMOBILE01 failed to connected to GYAP04 with SSID "GYWIFI" on channel 44 because the Association times out.(2 times in a minute) Sep 30, 2022 06:43:59    
[Failed]GYMOBILE01 failed to connected to GYAP04 with SSID "GYWIFI" on channel 44 because the Association times out.(6 times in a minute) Sep 30, 2022 06:42:29    

The GYMOBILE01 device was connected to the EAP620 HD whole night, link quality: 90+ %. Why should this mobile roaming to EAP615-Wall?? And of course it could not so a lot of "Association times out" messages were generated.

I think this is a EAP615-Wall related problem, have never seen on the EAP620 HD.

Hope somebody could help to find a solution. Thank you!
