4. Connect to Another Wi-Fi Network

This method can be effective because it will help you determine where the fault is arising from. If there is another Wi-Fi network accessible to you, connect to it and monitor whether it remains connected or disconnected. For example, if your iPhone disconnects just like it has been doing, the problem is with your iPhone, while if it remains connected, then the problem is with the previous router you were connected to.

The problem could be from the router and not from iPhone, and that is why your iPhone can’t stay connected to the Wi-Fi.

10. Change the Mac Address Filtering

Check if the Wi-Fi network you are connecting to has MAC address filtering turned on.
