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

Hey Zyxel community,

I have 4 NWA130BE distributed in the building and basically configured exactly the same way (except individual properties) and supposed to work as a "mesh" network. Their coverage overlaps. Until 7.20 this worked well but since then I noticed (particular for two APs) that from time to time an iPhone 16 connects and disconnects all the time. It seems to fully connect but then loses connection immediately again. This happens only with the iPhone. All other devices continue to work well.

Workaround solution: Restart the suspected AP. After that it works immediately until a couple of days later the same thing happens again.

Assuming many people use iPhones, has this been reported already?

Cheers,
Chris
