Wifi calling disconnecting after random time

[AdReg]

Hello, the GSM signal is very poor in my location so I'm enabling wifi calling. It works fine for few hours or even days but randmoly it gets disabled even though the button is enabled (the icon in the bar disapperas). switching off/on or setting airplane doesn't work. Only restarting phone works, after restarting wifi calling enables but after some time disables again.
I cleard phone data also radio setting data, nothing works. Onother phons in the same wifi like samsung phone works fine.
Do you have some idea how to fix it.

Welcome to Android Central! Are you able to test this behavior on another network?

In the meantime, try rebooting your router by unplugging its power for 30 seconds. This is worth trying even if other devices have no problem connecting.

Hi, I cannot use another WiFi to test because the time for issue is random. Unplugging also doesn't work, it happened many times.

In case something you installed is interfering, try booting into Safe Mode and see if the problem persists then: https://en-us.support.motorola.com/app/answers/detail/a_id/153514/~/safe-mode
