Those who have a smartphone or tablet on Android probably encountered such a nuisance as an authentication error. Android - although a popular operating system, is still not without flaws. Not all users understand what it is and how to fix it.
We'll put a word about authentication
Technically speaking, authentication is the process of verifying a security key. It is necessary in order to increase the level of protection of data that is transmitted on the network. And they encounter this procedure when using Wi-Fi.
Why is such a mechanism necessary? The fact is that Wi-Fi has a rather large range, so that not only the user who installed this technology can connect to it, but also attackers. To prevent unwanted consequences, data encryption technology is applied. An element of this mechanism is a password that must be entered when connected 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 malfunctions and problems on the provider's line. A similar result can be obtained in cases when large files are downloaded for a long time at high speed. But this is solved in most cases by an elementary reboot, and in some cases by setting up a router. In addition to this, there are two more reasons that stand apart:
- Data encryption type mismatch.
- Incorrect key entered.
Regarding the types of data encryption and security password for a Wi-Fi network, we can say that they are configured in the settings of the router used. For Android, it’s important only to enter the correct key. You don’t need to make or change anything else on your mobile device.
Solving the problem with Android
So, if there is a problem and a PDP authentication error occurs, we are primarily concerned with the Android device. First we need to check if the code is entered correctly. Make sure the wifi adapter is turned on. Find the network you need. Click on it and hold your finger until a menu appears where you can select "Delete data". This will reset all settings regarding this network.
Then we start the search for points to which we can connect. We find our network and enter the password for it. But first, you need to check the box next to the "Show password" line. Thanks to this, input characters will be visible. You need 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 persists, then there is a problem with the router. We need to go into its settings to check the type of encryption.
We work with a router
You must first connect to this device. You can do this using a desktop computer or laptop. There are no restrictions on the connection method (cable or Wi-Fi). After that, open the browser and enter the access point in the IP address bar. You can see it, as a rule, on the device’s body, in the instructions for it and not even its box. Also, IP control panel helps network management. For most devices, this is 192.168.1.1. A window will open and you will need to enter a username and password. This data can also be seen on the device. After that, access to the internal interface will be provided.
It should be noted that its design will vary depending on the model of the router, but in general, it is similar. The instructions written below can be applied to any device, there will be only minor deviations in writing, so you need to navigate by the semantic load:
- So, we went into the router. First you need to find "Advanced Settings" and click on them.
- A few additional windows will appear. As part of the article, we are only interested in the one called “WiFi”. We go to it and open the item "Security Settings".
- Typically, the first line is Network Authentication. This is the type of encryption that the Android device does not perceive. Select 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, then authentication errors when trying to connect will no longer have to be seen.
Conclusion
If it seemed that it was quite difficult to fix the authentication error, then we dare to assure you that it will take less time than it was necessary to write, and what is there to read this article. But if it does not disappear, try disconnecting and connecting with the password from a desktop computer or laptop. Perhaps the wrong key is just entered. If there is a problem after that, it probably exists at the hardware level.
