What is an authentication error?

Those who have a smartphone or tablet on the "Android", probably met with such a nuisance as an authentication error. Android - although a popular operating system, is still not devoid of flaws. Not all users understand what it is and how it needs to be corrected.

On authentication, put in a word

From a technical point of view, authentication is the process of checking the security key. It is necessary in order to increase the level of protection of data that is transmitted on the network. And they meet with this procedure when using Wi-Fi.

Why is this mechanism necessary? The fact that Wi-Fi has a fairly large range of action, so that it can connect to not only the user who installed this technology, but also attackers. To prevent undesirable consequences, and the technology of data encryption is applied. The element of this mechanism is the password that must be entered when connecting to the network.

Why an authentication error occurs

There is no single answer here. For example, budget models can simply generate internal errors that will lead to problems and problems on the provider's line. A similar result can be obtained in cases where large files are downloaded for a long time at high speed. But this is solved in most cases by an elementary reset, and in some cases by the router setup. In addition to this, there are two more reasons that stand apart:

1. Inconsistency in the types of data encryption.
2. Incorrectly entered key.

Regarding the types of data encryption and security password for a Wi-Fi network, you can say that they are configured in the parameters of the used router. For "Android" it is important only to introduce the correct key. You do not need to change or change anything on your mobile device.

Solving the problem with "Android"

So, if there is a problem and there is a PDP authentication error, we first of all deal with the Android device. First we need to check if the code is entered correctly. Make sure that the Wi-Fi adapter is turned on. Find the right network. Click on it and hold your finger until a menu appears where you can select "Delete data". This will reset all settings for this network.

Then we start searching for points to which we can connect. We find our network and enter a password for it. But first of all, check the "Show password" box. This will allow you to see the characters you type. It is necessary to check and make sure that everything was entered correctly.

It is possible that these actions are more than enough. But if the authentication error on the tablet or smartphone is saved, then the problem with the router. We need to go into its settings to check the type of encryption.

Working with the router

Initially, you need to connect to this device. You can do this using a desktop computer or laptop. There are no restrictions on the method of connection (cable or wi-fi). Then open the browser and enter the access point in the address bar. It can be viewed, as a rule, on the case of the device, in the instructions to it and not even on its box. Also, the IP control panel can help you. For most devices this is 192.168.1.1. A window will open and you will be asked to enter your login and password. This data can also be seen on the case of the device. After that, you will be given access to the internal interface.

It should be noted that its design will vary depending on the model of the router, but in general, it is similar. The following instructions can be applied to any device, there will be only minor deviations in the spelling, so it is necessary to navigate in terms of the semantic load:

1. So, we went into the router. First you need to find the "Advanced settings" and click on them.
2. Several additional windows will appear. Within the framework of the article, we are only interested in what is called "WiFi". Go to it and open the "Security Settings" item.
3. As a rule, the first line is "Network Authentication". This is the name of the type of encryption, which does not perceive the used device "Android." Choose WPA-PSK / WPA2-PSK2 mixed. This mixed type of encryption is supported by almost all modern devices. Then click on the "Apply" button and reboot the device.

If everything is done correctly, you will not have to see any authentication errors when trying to connect.

Conclusion

If it seemed that it was difficult to correct the authentication error, then we dare to assure you that it will take less time than it was necessary for writing, but what is there to read this article. But if it did not disappear, try disconnecting and connecting with the password from a desktop computer or laptop. Perhaps you just enter the wrong key. If there is a problem after this, it probably exists on the hardware level.
