3. Afterward, turn on your Wifi again and tap to the network you wish to connect to. Simply provide the credentials and tap on the “Connect” button to reestablish the connection. This way, you can reset the network successfully.

Modify network connection

If the above solution won’t work, then you would be required to walk the extra mile to fix the Samsung Galaxy S23 Ultra Wifi problem. After you reset a network connection, if still getting issues regarding the authentication of the network, you need to modify the connection. In this technique, you will be changing the IP settings on your phone to alter the way it establishes a secure connection. You can do it by following these steps.

1. To start with, visit your phone’s Settings and open the Wifi page.

2. This will display a list of all the Wifi networks that are associated with your device. Just long-tap on the Wifi network that you wish to modify. It will open another pop-up window.

Now, try to connect to the Wifi hotspot again. You would be able to overcome the authentication problem of Wifi.

Change Network Security Type
