Have you ever tried connecting with your WiFi system but faced an authentication problem?

Or have you tried connecting your Android device with the WiFi network you previously used with the phone but saw a WiFi authentication error?

You need not fret; this issue is common in selected Android devices and can be easily fixed.

The authentication error is sudden, even though you have used the right WiFi password. This can be quite annoying, especially in cases where you want to use the Internet connection urgently; this problem is far worse when you cannot access your mobile network.

This issue happens because of many different reasons. There might be an issue with your mobile device, WiFi connection, or both.

Here are some very simple solutions that can help you solve this authentication problem. All you need to do is follow these steps very carefully.

Part 1: What is the Meaning of the Authentication Problem in Your Wifi Network?

Authentication Error WiFi

The authentication problem occurs unsuccessfully when trying to connect with a WiFi network, even if you insert the correct password.

Typically, when trying to connect with a WiFi network, the mobile device, or any home appliance that runs on WiFi, will connect to the network and save the password automatically.

In this scenario, however, you will receive a notification that it is authenticating and then show the ‘authentication problem’ with the WiFi network you are trying to connect to.

When trying to connect to your WiFi network, your device first sends an encrypted request for connection, along with the password to the router. Then, the router will compare the stored password with the received data.

If both data match, a signal is sent from the router, and the device gets connected. In case it does not, it is known as an authentication problem. Hence, the Android authentication error WiFi problem will not allow the device to connect with the WiFi network.

Part 2: Why Does Wifi Authentication Error Occur with Android Devices?

The authentication error WiFi problem might occur for a lot of different reasons. Some common causes of this error include:

  • At times, the number of devices connected to a WiFi network is limited and based on user settings. Your device will not connect to the network if it is already connected to the maximum number of devices.
  • At times, people do not connect with the right WiFi network. At times, networks with duplicate names exist with different passwords. Connecting with the wrong WiFi network will lead to an authentication problem.
  • If the connection between the router and the device is not stable, it could also lead to an authentication problem.
  • The authentication problem might also occur if you have not updated the WiFi drives of your mobile devices.
  • When the router malfunctions, your device will not connect with the WiFi network, leading to an authentication error.

Part 3: Advanced Ways to Fix WiFi Authentication Error on Android

Most busy users do not want to spend a lot of time fixing this problem, so they resort to some advanced methods that are stated below:

Changing the Configuration of the Wireless Network from DHCP to Static

  • 2: Once you find the WiFi network you want to connect to, long tap on the name and choose Modify Network.
