If you are having issues connecting a Samsung Galaxy S21 to your wireless network there are several solutions.

When the Galaxy S21 does not connect to the WiFi or internet, the first thing to do is try a network reset.

When you reset the network service on your Galaxy S21, the great thing is you won’t lose any data or need to backup data prior to doing this as it does not erase anything.

As a last resort, if none of the above steps have fixed the issue, then you can complete a factory hard reset. When resetting to factory settings, make sure you have saved all data as it will be permanently deleted off the phone when complete.

To do a factory reset, hold the volume up and power button at the same time and let go when the Android logo comes up.

The Android recovery screen should come up, which will have the option to wipe all data.

If the Android recovery screen does not appear, you will need to hold both the power and volume up button until the Android Recovery Screen appears.
