[NWA130BE] Since 7.20, iPhone 16 toggles between WiFi and Celluar

Issue occured here again today. Diagnostic data was sent to @Zyxel_Melen

no

Unfortunately, there is not. At least not to my knowledge. I am in constant exchange with @Zyxel_Melen.

I have provided numerous diagnostic logs so far and Zyxel engineers are seeing disassociation handshake issues. A developer firmware was supposed to fix this but without success.

Recommendation from Zyxel is further to reduce channel width and other basic radio related settings in order to stabilise. But the issue even occurs with those changed settings. I don't see a relation either because the issue happens with the iPhone being placed right next to the AP.

I noticed recently that the issue is getting resolved as soon as I click on "collect now" in the diagnostic file creation process. I can reproduce this and Zyxel is now looking into this. Moreover I am being asked to provide WiFi traces to see if beacon transmission might be an issue.

So it is progressing somehow but it is also important that everyone is speaking up here becaue sometimes I have the feeling that Zyxel makes my environment responsible for this although this issue really only happens with the Zyxel APs.

P.S. It is my understanding that the iPhone 7 is affected as well. It is just not showing the "toggling" behaviour but rather remains on the mobile network constantly.
