SOLVING THE WI-FI CONNECTION PROBLEM WITHOUT RESETTING THE SMARTPHONE

Wi-Fi isn’t working on my phone: how to get internet back without resetting all data
If the internet on your smartphone or tablet has stopped working properly, the problem isn’t necessarily related to your Wi-Fi router or a weak signal.
If the internet on your smartphone or tablet has stopped working properly, the problem isn’t necessarily related to your Wi-Fi router or a weak signal.

Often, the problem lies with the device itself. In this case, resetting network settings may help – this feature is available in the settings of Android, iOS, and iPadOS, writes CHIP.de.

It’s worth trying this method if your smartphone or tablet:
does not connect to Wi-Fi;
Works with Bluetooth intermittently;
does not receive or make calls;
regularly loses connection during conversations;
cannot establish VPN connection.
Network settings can be reset relatively easily through the phone’s system menu. This preserves apps, files, and other settings—only network connection settings are deleted.

However, saved Wi-Fi networks and passwords will also disappear. Therefore, it’s recommended to back up this data before resetting, for example using a password manager.
How to reset network settings on Android and iPhone
The procedure is performed through the settings, but the exact path to the desired item depends on the smartphone model and operating system.

On Android: Open “Settings,” select “Reset settings,” then “Reset Bluetooth and Wi-Fi settings.” Confirm by tapping the reset button.
On a Samsung Galaxy, go to “Settings,” open “General Settings,” select “Reset,” and then “Reset Network Settings.”

On iPhone and iPad: Open “Settings,” go to “General,” select “Move or reset iPhone” (or iPad), tap “Reset,” and select “Reset network settings.”

Once the process is complete, reconnect to your Wi-Fi network and reconfigure your Bluetooth devices and VPN if necessary.
