@Steve7777: If you connect to an alternate Wi-Fi network, does this issue persist? This will help to determine if the problem lies with the phone, or your current network. You may also wish to head to Settings > Connections > Wi-Fi > Tap the 3 dots in the top right > Intelligent Wi-Fi > Switch to mobile data > Off > Switch to better Wi-Fi networks > Off, to see if this helps. Furthermore, tap the Back button > Tap the 3 dots in the top right > Advanced settings > Wi-Fi on/off history, and check to see if any apps are listed here that might be disabling your Wi-Fi, and adjust the permissions accordingly (if applicable).
