Fix 6: Check Internet Connectivity On Wi-Fi Router

While trying all these fixes, are we sure we even have internet connectivity on the Wi-Fi router? Because, in case we do not, iPhone may connect to Wi-Fi but will soon disconnect from it. This is by design to maintain active network connectivity. In case it finds no internet connectivity on Wi-Fi, it will switch to cellular/ mobile data. So, check your Wi-Fi router for Internet connectivity using your computer.

Your iPhone will show you if it finds there is no internet connection on Wi-Fi.

Step 1: Go to Settings > Wi-Fi

If you see a 'No Internet Connection' message, it means your iPhone has detected that your Wi-Fi router is probably not getting internet service in the moment.

Fix 7: Restart Wi-Fi Router

It is possible that something is stuck in the Wi-Fi router causing it to not accept your iPhone Wi-Fi connection. A quick restart of the router should resolve those issues, if any.

Fix 8: Reset Network Settings

Your iPhone knows how to connect to cellular and Wi-Fi through network settings. Major upgrades like the one from iOS 15 to iOS 16 often bring along modem firmware updates, and it helps to reset network settings so that the iPhone can use the new and updated settings to connect to networks.

Step 1: Go to Settings > General > Transfer or Reset iPhone
