• Unknown samsung security type. Authentication error when connecting to Wi-Fi on your phone

    Wi-Fi authentication error on Android can be caused by various reasons, there are two sources of reasons:

    1. Android phone or tablet
    2. wireless router or modem

    Input error

    The most common mistake is the incorrectly entered password for the Wi-Fi network on an Android device.

    When entering a password, you must respect the case of letters and do not replace capital letters with lowercase letters..

    If an error was made when entering the password, then to re-enter it, you need to click on the name of the desired network and in the menu that appears, click the “Forget network” / “Delete” button and re-enter the password.

    Router

    Another error may occur due to the router/router, to try to resolve the error you need to connect to the router. To do this, on a device that already has access to it, for example a computer, you need to type the router address in the browser.

    To find out the router address, click the “Start” button and type “cmd” and launch the command processor

    In the window that appears, type the command “ipconfig /all” and press enter


    We are looking for the line default gateway, this is the address of your router


    We enter it into the browser and press enter; to log in you may need to enter your name and password. Typically the name is "admin" and the password is "admin" "11111" "12345". You can find your username and password in your router's user manual. Next, look for the item “Wireless networks” / “WLAN” / “Wireless”, here we need to select the WPA2 encryption type and click the save button. Here you can view or change the password for the wireless network.


    After that, you can try connecting to the WiFi network.

    If after this the problem is not solved, you can try updating the router firmware.

    Bug Android

    In some versions of Android, the Wi-Fi authentication error occurs due to a bug in the Android operating system itself. To connect to a wireless network in this case, you can try selecting the WEP encryption type on the router or completely disabling encryption (see the steps in the previous paragraph).

    If you have any questions, ask them in the comments.

    After purchasing a tablet, one of the first actions of the user is to connect it to a WI-FI wireless network and configure it. This is done in order to further be able to install the necessary programs on the device. However, sometimes, while setting up a wireless connection, the tablet displays a system message about a WI-FI authentication error or other similar messages that are not very clear to a novice user. This, in fact, is where the connection to wireless Internet access ends. Next, we will try to understand the WI-FI network settings and the difficulties encountered in this process.

    Let's discuss the option of connecting a tablet based on Android OS. On all other operating systems the meaning will be similar, although the menu items may be located in different places. In the usual version, if everything goes well, the connection process is quite simple - you need to go to “Settings” of Android, in the “Wireless Networks” section, select “WI-FI”, turn it on (if this has not been done previously). Next, in the list of networks available for connection, select the one you need and in the window that opens, enter a unique password (if one is set). After this everything should work.

    If the list of available networks does not include the user's network, then you need to update this list. This can be done by clicking on the update button located in the upper right corner. After selecting and entering a password, Android will remember the network and the next time you connect there will no longer be a need to do all of the above. After a successful connection, a characteristic sign will appear near the notification line (in different Android firmwares they are at the top or bottom), which also shows the level and strength of the signal.

    If you couldn’t connect to your home router and the Internet still doesn’t work on your tablet, it makes sense to first check it on your laptop or computer. There may be a problem with the wireless network itself or with the router and its settings.

    Why may the tablet not connect to a working WI-FI network?

    Sometimes the error that “pops up” for users at the moment of connection is a message that this network is protected by a WPA\WPA2 password. In this case, you need to enter the appropriate password suitable for this network.

    It also happens that the network was selected correctly and the password was entered correctly, the tablet remembered it, but the connection never happened. There is also no error message. It is quite possible that the whole issue is in the settings of the router itself. To do this, you need to enter, using another, already connected device, into the router settings using the web interface, select the “Wireless network” item, and find the “Channels” item in it. By clicking on it, set the value to “Auto” in the window that appears. Often this problem can arise for those who just bought a WI-FI (router) and made mistakes in the settings of the latter. If this does not help, then we will analyze the basic scheme for checking the WI-FI (router) settings.

    To do this you need:

    1. restart the router;
    2. Make sure you entered the password correctly again;
    3. check that the “Channels” item is set to “Auto”;
    4. check the type of security and encryption;
    5. In the security settings, change the old password to a new one.

    If you don’t have confidence in your abilities, then it’s better to leave it as is, and use this list of tips if the others don’t help.

    Also, the main reason for authentication is an incorrectly or incorrectly entered password. The situation is that after the password has been entered and remembered on the tablet, all other connections occur with the same incorrect password.

    This problem can be corrected by the following steps:

    • On Android, go to “Wireless Networks”, select the desired network and delete it.
    • After that, click the “Update network list” button and re-enter the already verified or updated password.
    • If the password is entered correctly, it will be saved again and the Internet should work without problems.

    Other connection error options

    If the tablet does not connect to one specific network, but it is, for example, on a home computer using wireless WI-FI, you need to go back to the router settings. Next, select “Wireless Network”, and then enter the “Modes” section. Here change alternately to the values: b/g/n. After each mode change, you should restart the router and reconnect on the tablet.

    If after all it turns out that the problem is not in the tablet, but in the signal itself provided by the provider, then you need to contact your Internet service provider to eliminate this problem.

    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, 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 on the 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 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 queries for a 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 go into 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 ability to connect 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 boot loaders, 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.

    Owners of mobile gadgets, when trying to connect to Wi-Fi-based wireless networks, sometimes encounter the problem that the device, for unknown reasons, writes: “An authentication error has occurred.” Also, sometimes messages may appear about the message “Obtaining an IP address” constantly “hanging” on the screen, etc. How to fix such problems will be shown below. Looking ahead, it is worth saying that mobile devices are not always directly related to the occurrence of such troubles, and the root cause lies in incorrectly set router parameters. Next, we'll look at troubleshooting for home users, rather than for open networks that might be available in, say, cafes, restaurants or airports.

    An authentication error occurred: what do you mean?

    In general, the appearance of such a message indicates that when connecting to a wireless network, it was impossible to control (compare) the access key entered by the user with the one set for the network on the router. But this is far from the main reason.

    Samsung devices or some other devices may also issue a message that an authentication error has occurred due to the fact that the information encoding (encryption) systems may not match in the same way. As is known, this technique is used to prevent attackers from gaining access to transmitted and received information in order to use it for their own interests.

    Finally, the most common situation of a failure notifying the user that an authentication error occurred during connection may be associated with a weak signal (the capabilities of routers are limited mainly by a range of about 100-300 meters in line of sight).

    Based on the above, we will take appropriate measures, but only in relation to home conditions.

    What should I do if there is a WiFi authentication error in the first place?

    So, the very first thing that is usually recommended to do in such situations is to completely reboot all used devices that are somehow connected to the network (routers, phones and tablets). If there is a weak signal, simply move closer to the router and check the connection.

    Correctly entering the password and changing it on the router

    Quite often, a message indicating that a WiFi authentication error has occurred, Samsung devices or any other devices can also appear due to the usual carelessness of a user who entered an incorrect password to access the network.

    In this case, it is recommended to check the combination installed on the router and, if necessary, change it. To do this, log into the router interface using any web browser installed on a Windows system and go to the security password or encryption key line. After viewing, enter the correct combination on your mobile device.

    If you need to change your password, first do so on your router and save the changes, then enter the changed password on your phone or tablet to connect to the network.

    Note: you can find out the router address on the plate on the back of the device.

    To view the password on a mobile device, use the connection settings, long press on the Wi-Fi line to go to the settings, select change network and check the box to show the password.

    Changing the encryption standard

    If the mobile device again reports that an authentication error occurred, compare the encryption types installed on the router and the mobile device.

    In the router settings, refer to the corresponding line and set the authentication type to WPA-PSK/WPA2-PSK (Personal), and use the AES option for encryption. After this, on your mobile device, long press on the connection name, and then select delete network in the settings. After identifying available networks, find your connection and try to connect again.

    Wi-Fi channel selection

    If after this a notification appears indicating that an authentication error has occurred, you will have to move on to more drastic settings, which are made exclusively on the router.

    Log in to the router's web interface, as shown above, and go to the wireless network settings section (if the interface is not Russified, this is usually the Wireless menu). First, make sure that the region is set correctly, then from the drop-down list in the channel line (Chanel), alternately select one of the eleven present. Perhaps the connection will return to normal on one of them.

    Changing Wi-Fi mode

    Finally, if this doesn't help and the Authentication Error message appears again, take note of the Wi-Fi mode you've set.

    To solve the problem, in the Mode selection line, set the mixed type to 11b/g or 11b/g/n with the maximum data transfer rate, for example, 300 Mbit/s.

    What to do if nothing helps?

    Now let's see what can be done if none of the proposed solutions have a positive effect. In most cases, it all comes down to performing a full reset.

    First, perform the following actions on the router, using the appropriate section for this. After the reset, use the information you received from your ISP and set up your wireless connection again.

    Then, in the wireless connection settings on your mobile device, delete the connection you are using and confirm the “Forget this network” option. Reboot your device and connect again. If this does not work, reset the settings to factory settings on this device as well. But in most cases, such actions are not required on a mobile device. If this is still the problem, remember that personal data will be destroyed along with other information, so take care of creating a backup copy in advance by saving it on a removable memory card or on your computer (for a PC you can use even the simplest utilities like MyPhoneExplorer ).

    Instead of a total

    These are the main causes and methods for eliminating failures of this kind. If a similar situation occurs when trying to access open networks away from home, there is nothing left to do but contact the network administrator. At the very least, they will definitely give you the correct password to log in. Sometimes, however, it happens that when visiting the same establishment, these network accesses on the mobile gadget are saved automatically. If things don't work, the same security key may have been changed. Delete the existing connection, connect again and enter a new password (or use the change password for an existing connection as shown in the material above).

    It remains to add that most often there is no need to change the router settings (only in the most extreme cases), since in most cases the root cause of such a problem is the banal inattention of the owner of the phone or tablet, who is trying to enter incorrect data. But with Samsung equipment, the problem can actually be observed, since some devices by default use a different type of encryption than the standard one, which is why there is a discrepancy.

    Description:
    So, what to do if this unfortunate inscription appears? There are several reasons for this unpleasant situation and options for getting out of it.
    Sometimes the phone does not connect to wifi and says wpa2 protection is saved. This can happen both when trying to connect to a public network or to a home one. This mostly applies to Android devices. This can be done equally by tablets and smartphones.
    So, what to do if this unfortunate inscription appears? There are several reasons for this unpleasant situation and options for getting out of it.
    Let's start by rebooting the router
    1. Select the correct region. To do this, go to the "Wireless" tab and in the "Region" line, select the name of your country and save.
    2. Check the wireless network password. Before changing your password, try connecting again. To do this, click on your network and delete it. Then click on the network again, enter the password, make sure it is correct and try to connect.
    3. Check the Wi-Fi network operating mode in the router settings. This may be the main cause of the problem. Your tablet or smartphone may simply not support the operating mode of this router. Check whether the device will work with other parameters, remembering to restart the router and disconnect and connect Wi-Fi on your smartphone or tablet after each change you make.
    4. Check the security type and encryption type, change the router password in the settings. You need to set the following: WPA/WPA2 – Personal, WPA-PSK version, AES encryption. The PSK password must consist of eight digits. Then we save the new settings, reboot the router and disconnect and reconnect the phone. Don't forget to do the same on other devices running on the same wireless network.
    5. Change the working Wi-Fi channel. Of course, this rarely happens, but it’s worth trying to experiment with the channels to be one hundred percent sure.
    6. Change the width of the connection channel. To do this, you need to go to the router settings. In the “wireless network” tab, change the value opposite the “channel width” line, save the changes and reboot the device.
    In conclusion, answering the question why an Android phone does not connect to wifi, writes saved protected, it is worth noting that this could be both technical problems and a number of errors associated with forgetfulness or inattention of users. There is an opinion that the reason lies in the Android OS itself, or rather in small flaws that cause various unpleasant moments. But if it happens that there is a problem with your Wi-Fi connection, you can successfully deal with it using these tips.
