Users have complained that their iPhone no longer connects to their personal Wi-Fi network.
The initial solution is to restart your iPhone and check the Wi-Fi connection. Make sure that the router is working fine and that it is updated to the latest firmware. It must also support an Apple product. If the issue is not resolved, try connecting to a Wi-Fi network after trying Network Settings Reset under iPhone Settings. However, if these fixes do not lead to success, upgrade to a newer version or restore a previous version
