Saved wpa wpa2 protection what to do. Authentication error: why it occurs and what to do

Quite often, many users of devices running mobile operating systems encounter an unpleasant situation when the device displays an authentication error when connecting to a wireless network. Such problems can equally be attributed to stationary systems, but it is in them that failures of this kind are much less common. For them, a method for eliminating the problem will be proposed separately, but for now we will focus on Android devices. It is to them that the occurrence of this failure is most often attributed. Accordingly, the proposed methods for eliminating such situations are mainly designed for mobile rather than stationary systems, although they cannot be discounted. But first things first. And first, a few words about the nature of the failure itself, without understanding which all solutions to correct the situation may turn out to be completely ineffective.

What is an authentication error in a general sense?

Let's look not even at the error itself and the nature of its failure, but at the authentication process itself. Don't confuse it with initialization and authorization. These are different things.

Authentication when trying to connect to a WiFi-based wireless network is a check of the key entered for access, or, more simply put, the password that is used in the settings of the router or stationary computer device that distributes the signal to prevent unauthorized connection.

The most common situation associated with the appearance of a Wi-Fi authentication error is the usual inattention of the user himself, who enters the wrong combination as a password. In this case, you should go to the network settings, select change parameters and check the box next to the password display line, and after entering, compare it with what is used as the default access key.

Authentication error when connecting to WiFi: reasons for the failure

However, in most cases, this is not the main problem. It may very well be that the mobile device and the router have different types of protection or encryption installed for data that is transmitted over a secure connection. Sometimes there may be short-term disruptions. It is especially worth noting that the router settings were incorrectly set in terms of selecting the connection type and the channel used. You can deal with all this using completely elementary methods, after which the problem will disappear. Below are several basic techniques.

Checking the current operating mode of the mobile device

So, we assume that when trying to connect to a network, the device generates an authentication error. What to do?

First of all, check the operating mode of the device. Every user should understand that when Airplane mode is activated, absolutely all connections are blocked. It may well be that you tried to set the silent mode by lowering the speaker volume, but accidentally made a longer press, which activated the corresponding Airplane mode. Just unplug it and check the connection.

The simplest method to resolve the error

WiFi authentication error on Android, strange as it may sound, can be associated with short-term system failures, especially when you have some kind of optimizer installed that disables all background services to speed up the device.

Try simply rebooting the device, but do not use a restart for this, but turn off the device completely and turn it on again.

If we talk about home users whose Android system gives an authentication error when connecting to WiFi at home, the problem may also be related to the router itself. Perform a full reset by turning off the power completely for about ten to fifteen seconds, then turn the device back on. Some experts advise taking a longer pause (up to ten minutes), although I think this initial period is quite enough.

Difference in encryption systems

Let's understand a little about what an authentication error is. Now a few words about the most common reasons for its appearance. The problem is that the router and mobile device may use different types of selected security systems.

Very often this problem occurs with mobile devices of the Samsung Galaxy model range. The router is set to WPA-PSK Personal by default, and the phone is using WEP. This mismatch causes the device to generate a WiFi authentication error.

Router setup questions

Thus, this problem can be resolved by setting the correct parameters on both the router and the mobile device.

You can use automatic settings on the router, and as an additional option, select a mixed connection mode (11b/g or 11b/g/n). Typically, these settings are located in the Wireless section. Yes, here's another thing. Don’t forget to check whether distribution is enabled on the router, otherwise the Internet connection indicator may blink, the provider’s router will be detected by external ping, but there will be no connection and there will be no connection.

Setting a priority channel on the router

There is another common problem related to the settings of the used channels allocated for connection. In this case, a failure message may also appear. What is the authentication error in this case? Nothing more than the inability to connect via an automatically selected communication channel.

To fix the problem, log into the router’s web interface through any browser installed on a desktop computer system (for example, in Windows), and in the corresponding settings item, alternately select the use of one of the eleven available channels, saving the settings and checking connectivity.

Pairing setup

Finally, one of the global solutions to the problem of interconnection of mobile equipment with routers or stationary distribution devices is to establish pairing with standard IP protocols of the fourth and sixth versions. You need to set such options specifically on a smartphone or tablet.

The sixth protocol, apparently, will not have to be used, since in the post-Soviet space there are not so many providers using DHCP servers of the sixth version. Therefore, you can limit yourself to pairing with IPv4.

Windows Solutions

But so far everything described has applied mostly to mobile systems. You shouldn't forget about Windows either. This is especially true for situations when a distribution server is installed on a computer or laptop.

As a rule, the IPv4 settings indicate automatic acquisition of addresses of all types, but often the problem may be that the system cannot convert standard requests to domain name into a digital combination, for which DNS servers are responsible.

To fix the problem, try simply changing the settings of the preferred and alternative DNS server, setting the parameters in the form of free Google combinations (options with eights and fours).

Sometimes, if distribution is not taking place, it is necessary to call the services section (services.msc in the “Run” menu), find DNS and DHCP clients there, check their status (they must be active with the priority set to “Running”). If the services are stopped, you should enter editing options (double click or RMB menu), press the start button to start them manually and set the startup type to automatic. After completing all actions and saving the settings, the computer system should be rebooted without fail, and after the restart, check the possibility of connecting via WiFi.

Another common problem is blocking of incoming and outgoing connections on the created server by installed standard antiviruses and the Windows firewall. At least, the occurrence of such situations is very often associated with the Avast package.

To fix the problem, disable your antivirus for ten minutes and check the connection. If it works, get rid of this software. If there is no effect, deactivate the Windows Firewall.

If you suspect exposure to viruses, use portable scanners like KVRT or Dr. Web CureIt, but it is best to check the system before starting the download using disk applications like Kaspersky Rescue Disk. The uniqueness of such utilities is that when recording to removable media, you can use the built-in bootloaders, select a graphical interface and scan the computer system even before Windows boots. Such tools are not provided for mobile systems (unfortunately).

The maximum that can be used is mobile antiviruses or programs that disable all unnecessary services, such as Root Booster. Such applications, however, will require superuser rights, but the effect of increasing productivity cannot be compared with anything. In practice, this particular utility has shown itself to be the best.

Instead of a total

In general, if we summarize what an authentication error is, it should already be clear. And you shouldn’t associate its appearance exclusively with mobile systems. As follows from the material presented above, if there are distribution devices based on a virtual server for Windows systems, the occurrence of such a failure is also no exception. As for troubleshooting, of course, you should start with the settings of the router and mobile device, since the same types of protection systems may not match. Otherwise, the proposed solutions can be used exactly in the order of their description, although in most cases it can be quite difficult to name the true cause of the failure, especially since the error message itself almost never indicates anything particularly specific about the description. And this is precisely the biggest disadvantage, because of which it is simply impossible to initiate a failure.

Hi all!

I analyzed a little of the comments that visitors leave on the site, checked the requests and realized that there is a very common problem with connecting to Wi-Fi, which I have not written about yet. But many comments were left on the site asking for help to solve this problem. I advised something there, but I don’t know if my advice helped you (rarely does anyone write about the results 🙁).

And yesterday, Roman (Thank you kind person :) I left a comment on the article in which I shared information about how he solved the problem “Saved, WPA\WPA2 protection”. This comment helped me understand the problem a little, and I decided to collect all the tips for solving this error in one article.

The essence of the problem

When connecting a phone or tablet (most likely on Android), to your home network, or somewhere in a cafe, an inscription appears next to the name of the network “Saved, WPA\WPA2 protection”. And nothing else happens. If you click on this network and select Connect, then nothing will happen. You can see what this error looks like in the screenshot above.

I specifically provoked this problem on my Asus RT-N13U Wi-Fi router and tried to connect an HTC One V (Android 4.0) phone. So I got this message “Saved, WPA\WPA2 protection”. Moreover, everything worked out the first time. How? Yes, very simple. In my router settings, “Wireless network mode” was set to Auto mode, and I set it to n Only. I saved the settings, disconnected the phone from Wi-Fi, but it was no longer possible to connect :)

The main causes of the error “Saved, WPA\WPA2 protection”

Friends, I cannot say exactly everything and give advice that will be one hundred percent working, I hope you understand. All devices are different, everyone has different settings and many other nuances.

But I will try to collect the reasons known to me and ways to solve them, through which such a problem with connecting to a wireless network may arise.

If, when connecting to a wireless network, you see the message “Saved, WPA\WPA2 protected” on your phone (maybe a little different), then it’s worth checking these settings (I advise you to check in the same order):

To get started, simply reboot your router.

I have already noticed this problem several times: the Internet on the phone simply stops working, but there is a connection and the network is good. I turn Wi-Fi off and on on my phone, but it no longer connects to the network, it says “Saved, WPA2 protection.” Only rebooting the router helps.

1. Set the correct region in the router settings
2. Check whether the password for the Wi-Fi network is correct
3. Check (change) the wireless network operating mode in the router settings
4. Check (change) the encryption type and security type, change the password in the router settings
5. Experiment with changing the channel on which your wireless network operates.
6. Try changing the channel width.

And now in more detail on all points

Set the correct region in the router settings

Very often, this error occurs precisely because the Wi-Fi settings are set to the wrong region.

Using Tp-Link as an example, I will show you how to change the region. If you have a router from another company, then these settings are most likely changed on the same page where you set the name and other settings of the wireless network.

In Control Panel, go to the tab Wireless (Wireless mode) and opposite the point Region indicate the country you are in.

Save the settings by clicking the button Save(Save) .

Check your password and connect again

Perhaps you simply entered the password incorrectly (however, then most likely there will be a constant connection, in a circle. But you need to check), and before getting into the router settings, I advise you to check this.

You may ask, how can I enter the password again, because the password request does not appear. You need to delete the connection. Just click on your network and select Delete.

Now, click on your network again and enter your Wi-Fi password. Just make sure it's correct. If you forgot, look at the password in the router settings, or on the connected computer (if there are any). Read more in the article.

Checking the wireless network operating mode

It seems to me that this is the main reason. Just your device (phone, tablet) may not support the operating mode in which the router operates.

The operating mode is those incomprehensible letters b/g/n, which you probably already noticed in the router settings. Try experimenting with changing modes. Don’t forget to restart the router after each change and turn off/on Wi-Fi on your phone (tablet).

So I installed n Only instead of Auto and an error popped up. And if, for example, you already have n Only in your settings? Here are your problems.

Changing the encryption/security type, password

It may be that your device simply does not like the type of security or encryption that the router uses. Or you don't like the password.

I advise you to set the following values:

WPA/WPA2 - Personal (Recommended)

Version: WPA-PSK

Encryption: AES

PSK Password (key) – at least eight characters and numbers only.

We save, reboot the router, delete the connection on the phone, and connect by entering a new password.

Attention! After changing the password or other security settings, problems may arise with connecting other devices that were already connected to this network (computers, laptops, TVs).

Experimenting with the channel on which the Wi-Fi network operates

It's unlikely, of course, but it could be. I wrote about what a wireless network channel is, how to change it and why in the article -.

Try experimenting and see if it helps.

Channel width

There is such an item in setting up a Wi-Fi router as Channel width. If you have, for example, TP-Link and the menu is in English, then it is called Channel Width.

There you can select several options: Auto, 20MHz and 40MHz - depending on the router. Try installing first Auto(or in Asus 20MHz/40MHz), if that doesn’t help, then separately.

Where can I change the channel width?

Go to the router settings ( address 192.168.1.1, or 192.168.0.1, enter login/password - look at the bottom of the router).

Asus

Go to the tab Wireless network and change the value opposite Channel width.

TP-Link

Tab Wireless – Wireless Settings, paragraph Channel Width.

Don't forget to save the settings and reboot the router.

Afterword

I seem to have written everything I wanted. I really hope that my advice will help you. You will get rid of this problem and connect your phone or tablet with a Wi-Fi router :)

Perhaps you know other solutions to this problem, share them in the comments - I will be grateful!

Best wishes!

The phone (tablet) does not connect to Wi-Fi, it says “Saved, WPA\WPA2 protected” updated: February 7, 2018 by: admin

We have already raised the topic of connection in one article. Methods for eliminating problems that arise during the connection process were described there. Now let’s try together to figure out the authentication problem that many users encounter when connecting their device to a wireless network.
To make it clear what will be discussed next, let’s assume that you, according to , turned on the wireless network, selected the one needed for work, entered your password and clicked the “connect” command. The problem is that after this, instead of connecting to the router, the device is in the state for a long time "Authentication".

How to fix the "Authentication Error" problem on your tablet

• The password for the wireless network was entered incorrectly;
• If the router security type set in the settings does not suit your tablet.

We start with a normal router reboot.

In principle, the described actions are a method for eliminating problems that arise with device authentication. But if you still can’t do this, write in the comments and I’ll try to figure it out.

Authentication error when connecting to home Wi-Fi is perhaps the most common problem that occurs on an Android phone or tablet. In order to eliminate it, you need to understand the basic principles of the device’s operation, as well as know what authentication is and why it is not performed.

You cannot solve a problem without understanding its essence. Wi-Fi authentication is the process of verifying a security key. In simple words, the set network password matches the one entered by the user. The main task of authentication on a phone or tablet is to protect the network from unauthorized access.

Not every user understands that any devices connected to a single Wi-Fi network can easily exchange data. This is why open Internet connection points are considered unsafe. In order to connect to a wireless network without fear for the safety of your data, an authentication process was invented. The most common way to authenticate a user is to prompt them for a password.

How does authentication work?

1. The user connects to the network, then enters the security key;
2. an Android tablet or phone encrypts the entered information and sends it to the router;
3. the router decrypts the data;
4. depending on their compliance or non-compliance, denies or allows the user to connect.

This is why if you enter the password incorrectly, an error occurs. In this case, the Android device writes that you were unable to complete the authentication process, and the phone or tablet does not connect to the Internet.

Steps to connect to wireless Internet

Before connecting to a wireless network, make sure that the wifi module on your Android phone or tablet is turned on. To do this:

• go to your phone settings;
• go to the wireless networks menu;
• If your phone or tablet tells you “to see available networks, turn on wifi,” then move the slider at the top to the right position.

After a few seconds, a list of available wireless networks will appear here. If you see a “lock” next to the wifi icon, then you will need to go through an authentication process to connect.

enable the “show password” feature

Decide which wireless network you want to connect your mobile phone or tablet to. Click on it. After this, a dialog box will appear on the display of your device with its name, information about the signal level, type of protection and a field for entering a password (if it is protected). In order not to make a mistake in entering it, scroll down the dialog box and check the “show password” box.

This way you will see exactly what characters you are entering. After entering the appropriate password combination, click the “connect” button. The phone or tablet will report that it has successfully connected to the selected wifi network or an error will appear.

Main problems

It often happens that when you enter the wrong password and try to connect to a wireless network, the phone or tablet under its name, instead of the “connected” message, writes: “Saved, protected by WPA2” (WPA2 is the type of network used, so it can change). Then there are several authentication attempts and eventually the message “authentication error” or “network connection error” (which is basically the same thing) appears. In such a situation, the user has basic questions: what to do and why does the error appear?

There are three most common problems that prevent an Android phone or tablet user from completing the authentication process:

1. incorrectly typed password for connecting to wifi (security key);
2. mismatch between the router data encryption type and the settings on your phone or tablet;
3. wifi router malfunction.

Depending on the type of problem, the ways to solve it differ.

Incorrect password

Click on the name of the wireless network that is giving you an authentication error. After opening a small dialog box, select “delete”. Don’t worry, it won’t disappear anywhere, but will appear again in this list, after which you can repeat the operations performed by entering the correct password. Don't forget to check the "show password" checkbox. Double-check the key carefully. Users often confuse the symbol zero with the letter “o”, one with the Latin “i” and “l”, the capital letter “I” (i - “ai”) and the small “l” (L - “el”), and so on. Don't forget that the password may be case sensitive (small and UPPERcase letters).
If you are sure that the entered password is correct, but your phone or tablet on the Android operating system still displays this error, turn off the Wi-Fi module and turn it back on and try to connect to this network again, or completely restart your mobile device and try to connect again.

Faulty router

Also, the problem may lie in the router itself that distributes the Internet. In this case, you can try to connect to other wireless networks, other routers. For example, to free Wi-Fi in restaurants, shops, etc. If the problem persists, then most likely you will have to completely reset your smartphone to factory settings. At the same time, do not forget to backup the information stored on your android phone or tablet, otherwise you will lose it.

Data encryption type mismatch

An authentication error may appear due to a data encryption type mismatch or an unknown wifi network mode for the device. The problem is resolved by changing their types. To do this, you need to connect to the router (via Wi-Fi or using a cable) and enter the router settings. Enter the access point IP in the address bar of your browser (this information can be found on the case, box, or in the router instructions).

How to find out the IP access points through the Network and Sharing Center

• open the “Network and Sharing Center”;

• find the line “connection” and select “wireless network connection”;

• in the dialog box that opens, click on the “details” button;

• “default gateway IP v4” is the IP of the access point to the router.

Changing the encryption type in the router settings

After entering the IP access point in the browser, you will be taken to the router settings, where you will need to enter a login and password (default: admin, admin). Depending on the manufacturer and model, the program interface may differ.

• after successful authentication, open the advanced settings of your router or router;

• select automatic data encryption type or WPA-PSK/WPA2-PSK2 mixed;
• in the same menu you can change the wireless network password;
• click the "save" or "apply" button;
• reboot your device;
• You don’t need to do anything else, so you can close the router settings.

If you did everything correctly, then the problem of Wi-Fi network authentication on your Android phone or tablet will no longer ruin your life.
