Have you screenshot of you SSID and roam settings?

  @MR.S 

Sure. But again - the way eap650 to er706w ist working. vice reversa not.

ER706W

EAP650

eap650

  @kogan 

Ok, I did a test here with an old EAP225-Outdoor which I wirelessly meshed to the router to test. there was no problem with roaming for me.

there is a slight difference between my config and yours, I use PPSK and then it is not wpa3, but try to disable 802.11r this can often cause problems.

  @kogan 

and if it were me I would use channel 112 on the ER706W and channel 60 on the EAP650

you have a large overlap on your channels since you are using 160Mhz bandwidth.

What firmware do you have on the EAP650?

It is also not always wise to use 160Mhz bandwidth since there will be fewer channels without overlap. I have experienced that with 160Mhz, even if the connection speed is higher, you get a much lower transmission than with 80Mhz, so I have stopped using 160Mhz.

Hi

non of your suggestions worked. sorry.

of course it is the newest firmware. 1.0.10

another point, why I want to use chn. over 100, because the signal is stronger - 23 dBm vs 28 dBm

  @kogan 

ok, maybe there are some incompatibilities between EAP650 and ER705W, as I said I tested with EAP225-Outdoor and it roamed very well both ways.

  @MR.S 

working in both directions?

obviously you dont use AX, only AC. On AX is only WPA2/WPA3 AES possible...

thanks anyway!

  @kogan 

ER706W is AX and EAP225-Outdoor is AC, and yes you can use wpa2 on AX but you have to remove 6Ghz on SSID. and EAP650 or ER706W not Have 6Ghz so this is not very useful for you.

  @MR.S 

thank you!

@Hank21 @Clive_A 

I found the "bug" - which is obviously a real bug.

After deactivating 6GHz, I was able to downgrade to WPA2 only, since then roaming is working in both directions.

I also tested again and switched to WPA3 - EAP650 to ER706W is working perfect, from ER706W to EAP650 it is not switching back...
