Samsung Galaxy S4: Wifi Authentication Problem

At times, the Samsung Galaxy S4 displays the Authentication Problem message when ever you try to connect to a Wi-Fi network. This sort of error message can possibly originate from several places. So, so that you can connect properly to the Wifi network with your Samsung Galaxy S4, we decided to produce this tuto. So we will find out together what to do and where to look to resolve this issue of Wifi authentication. We will see at first of all what you have to do on the Samsung Galaxy S4. At last, we will see what it can be required to do and check on your Wifi box.

How to proceed when the Samsung Galaxy S4 has an authentication problem on the Wifi network

Forget the Wifi network on your Samsung Galaxy S4

If perhaps the Wi-Fi network to which you want to connect has been changed since your last authentication, your Samsung Galaxy S4 may display the message: Authentication or authentication error . If perhaps the problem comes from there, the solution is quite easy. Just forget about the Wifi network in your Samsung Galaxy S4. To achieve this, go to the settings of the Wifi network and keep pressed on the network in question. You will then have the option to choose the option: Forget this network . When it’s carried out, you can try again to connect to the Wifi network. If perhaps the problem is not fixed, go to the next step.

Press the box button

Whether your box is Orange, Bouygues Telecom, SFR or Numéricable, it may possibly happen to have a problem of authentication Wifi on the Samsung Galaxy S4 because the box is not in Synchronization mode . If you would like to activate the synchronization mode of your box, it can be very simple. You should find a synchronization button to press. When ever this is carried out, a light will most of the time start blinking. You can actually then try to reconnect to the Wifi network with your Samsung Galaxy S4. If perhaps it still does not function, go to the next trick.

Retype Password

At times the authentication problem originates from the technique you type the Wifi network security password. In fact, it can be sometimes subtle to type a security password Wifi on its Samsung Galaxy S4. We therefore advise you to try all the following possibilities:

  • Type the code without spaces or hyphens
  • Type the security password in uppercase
  • Type the security password in lowercase

Restart your box

As in lots of computer problems, the solution is at times very simple. In fact, 80% of the computer problems are solved by restarting the machine. We therefore recommend you to restart your box and your Samsung Galaxy S4. Then try to reconnect with your Samsung Galaxy S4.

Check box settings

If perhaps non-e of the prior solutions did function, the problem could possibly be found to be on the box of your provider. It will therefore be required to go in the parameters of the box and to check in the event that the system of key is in WPA / WPA2 . If perhaps this is not the case, choose this option. Then try to connect your Samsung Galaxy S4 again to Wifi. If perhaps the authentication problem persists, we advise that you contact your service provider or a telephone retail store.
