Hence, you need to be in a specified range of the WiFi router.

Usually, the range of WiFi varies, depending upon the frequency. A 2.4GHz frequency could be able to provide you with a range of 150 feet or 45 meters. While a 5GHz is higher in frequency but will provide you with a shorter range of 50 feet or 15 meters.

Check the Band Compatibility

As the Samsung Galaxy S23 Ultra 5G comes with support for 2.4GHz and 5GHz bands. Depending on the user’s choice, it can be connected to one of these bands.
