Your device Android meet a Wifi authentication problem ? Don't worry. This problem is not that serious, and in most cases it can be easily fixed.

Let's see why this is happening and how we can fix it.

Causes of WiFi Authentication Error

First of all, to connect to your Wi-Fi network, you need to enter the password.

Then your phone Android sends the network password and connection request in an encrypted format to the Wi-Fi router.  The router decrypts the password and compares the password stored on it.

Now if the password matches, it sends an affirmation for the connection request, then your phone is allowed to connect to the network.

A Authentification error occurs when the “agreement” between the Wi-Fi router and the device fails due to some reasons.

Here are some of the common reasons you get a Wifi authentication error:

There are several methods to resolve the Wifi authentication problem. Here are some of the common solutions that you can easily try.

Verify Password

When entering your Wi-Fi password, pay careful attention to each character, as a clear distinction between upper and lower case is crucial. Indeed, a small mistake can prevent you from logging in.,

If you're ever confused about the correctness of your password, remember that the label on the back of your router often contains the necessary credentials.

Restart the router

The easiest and fastest solution for fix authentication problem is restarting your router.

Restarting the router may do the trick and restore the Internet connection.

And the best and most common way to restart it is to unplug the power cable. This will turn off the router. Wait a few minutes before plugging the power cable back in and turning the router back on.

Reset the Wifi network

If the first method did not resolve your WiFi authentication error, the problem may be with your phone itself.

Try to reset the network on your mobile. To do this, you must first forget the respective network and then reconnect again. This can be done by simply following these steps.

  • First, go to the your phone settings> Connections> WiFi. From here you can see a list of all the Wifi connections your phone has been connected to. Select the network you want to forget.
  • When you select a network, it provides basic information related to it. Just press the button “ Forget the network » and accept the pop-up message. This will erase the network information from your device.
  • Next, turn your Wifi back on and tap the network you want to connect to. Just provide the credentials and press the “button Login » to reestablish the connection.

Adjust allowed connections

If there is an Internet connection but you still cannot connect, it may be because many users are already connected to the router and you have reached the maximum number of connections allowed.

Follow these steps to adjust this setting and resolve the issue:

  • First, open a web browser and enter your router's IP address (usually "" or "").
  • Next, enter your username and password. If you've never changed them, the default credentials are usually on the back of the router, often in the form "admin" / "admin" or "admin" / "password".
  • Look for the wireless or WLAN settings section.
  • Next, find the option for the maximum number of connections or users allowed
  •  Just adjust the maximum number and restart the router. Make sure you don't exceed your router's capacity though, as this could slow down your network speed.

Use a static IP address instead of DHCP

Another reason why you are experiencing this authentication issue is due to a IP conflict.

DHCP is a protocol which is responsible for the automatic assignment of IP addresses to the various devices connected to the router.

Sometimes this DHCP protocol can cause IP address conflicts. So, you'd better change "DHCP" to " Static » to see if the authentication error persists.

To do this, follow the steps below:

  • First, open Settings and select a WIFI connection.
  • Now long press on the Wi-Fi name and select Manage network settings.
  • Check the box Show advanced options and change the IP settings to static.
  • There you will see the IP address field. Write it down, then save the information to a static IP address and delete it.
  • Now wait for a few seconds and enter the same information and hit save.

Resetting the Router

When you have exhausted all other solutions and are certain that the password you entered is correct, it may be a good idea to consider a complete reset of your router.

This action will return your router to its factory default settings.

Here's how to do it:

  • First, find the reset button on your router. It is usually located on the back of the device and may be labeled " Reset"
  • Then, while the router is on, take a paper clip.
  • With this last, press the reset button. It is crucial to maintain it between 10 and 30 seconds depending on the model.
  • Release the button and wait for the router to reboot.
  • After resetting, log in to the router interface with the default credentials (see the back of your router). Once connected, you can configure the router as if for the first time.

So ! You have finished. Now check if the issue is resolved or not.
