Fritzbox WLAN IPAD?

I have a problem and ask for help… Currently I have an IPad (6Gen) and a mobile phone (Huawei P30 lite) My problem is that my phone is connected to our wireless Internet connection has only the iPad connects to the Wlan ( I see in the settings but not in the system tray.)

And after a time is in the settings: No connection (No Internet access) I've restarted my Fritzbox and also disconnected and rewired the Wi-Fi.

Look if the MAC address filter is disabled on the FritzBox.
