No internet connection just for android devices.

IoT devices and laptops connects good as previously.

Tried rebooting ISP router, Deco and android devices numerous times.
MAC adresses as sugested set to static.

Tried updgrading to beta firmware (1.7) as suggested in other post, but problem perssists.

This is happening in Wifi-Router Operation mode.

When i switch to Acces Point Operation mode, then android devices have internet, but some IoT devices (Shelly s1 Gen3) doesn't connect.
