If the tablet does not catch Wi Fi. Why the tablet does not connect to WiFi. Wireless mode

The tablet does not connect to WiFi not only when problems with the network occur. Perhaps the problem lies in the tablet itself.

Consider how to solve the breakdown.

Users tablets on Android are often faced with non-working WiFi. Almost all causes of the problem you can solve yourself.

Incorrect password entry

In one of the most common mistakes, the user is to blame - this is the introduction of an incorrect password.

If you do not know why you can not with the Internet via WiFi, when you enter a password, click on the "Show password" checkbox to make sure that all the letters and numbers are entered correctly.

If you enter the access code correctly, you should consider the following possible reasons The breakdowns that are presented below.

No settings with the tablet holder should not be carried out, it can only aggravate the situation.

All actions will be carried out exclusively with the router.

Problems with the operation of the router can occur due to its incorrect setting, when too many subscribers are simultaneously connected and used the device, interruptions in electricity and other problems.

Disconnect the router from the network for several minutes and then turn on again, this method can also solve the problem with the connection.

Check algorithm used encryption

If your tablet does not connect to the router, and the status bar writes saved, the cause of the problem - different types Encryption that use the tablet and router.

If a new encryption mode is selected on the tablet, rather than on the tablet, the user will not be able to pass authentication, thereby entering the Internet to be implemented.

Such a problem is common on Samsung and Lenovo brand tablets.

Follow the instructions to set the same encryption types and solve the problem:

• Enter the router settings. To do this, you need to connect to it using your personal computer or laptop;
• Open the browser;
• Enter the router address in the address bar and press Enter (the IP address is reset on the router panel or in the instructions).
  If you did not find such data, remember that the router, depending on the manufacturer and model, can take only one of two local hosts: 192.168.1.1 or 192.168.0.1;

• To accurately see Local IP, go to command line And enter the ipconfig command in it.
  Find the field called "Main Gateway" and at the right column Look at it value - this is the local address of the router in home network. An example of working with the command line is shown in the figure below;

• Register the address found in the browser;
• Enter the login and password from the browser admin. View login data in instructions for the device (router);

• On the tab fast settings Check the type of encryption of the router. Place this type as on your tablet. Encryption type that uses android device is specified called WiFi in the Connection window.
  An example of viewing the encryption type that the router uses is shown in the figure below;

If you set out all the settings, the devices authentication will pass normally, and you will find that the tablet sees the network and connects to it.

Mac filter

Invalid filtering of the so-called addresses Mac - another common cause of errors when connecting the android device to the router.

As a rule, the problem occurs on tablets asus And Lenovo in the process of their interaction with low-cost budget versions of routers.

To improve the level of connection protection, it will be necessary to determine the MAC address - the physical address of the computer in the Internet network.

If this address is not defined for any reason, the router closes Internet access.

This may be the reason that the tablet stopped connecting and an error appeared.

To fix the settings of the MAC address, follow the instructions:

• Go to the router settings. How to do this in detail described in the previous instruction of the article;
• Go to the "Network" tab. The names of the tabs may differ depending on the model of the router used. In the "Network" tab, make sure that the MAC address of the device and computer is identical;

• Press the save key, restart the router and device;
• Connect to the router again. Everything should work stably.

Important! You can find out the physical address of the user tablet on the manufacturer's official website or in the instructions for the device. Physically address is a unique identifier.

Also in setting the router, you can turn off the filtering. Do it if you could not find the personal identifier of your device.

You can disable filtering in the "Network" tab in the main router settings.

As a rule, turning off the filtration solves the problem.

To start working with the Internet, restart the tablet and router.

On the tablet, enter the access password again, the connection process after deleting Mc addresse settings may take a few minutes.

Channel Setup

If even after turning off the filtering, you failed to connect to the Internet, check the channels.

The inconsistency of the channels used can also cause a malfunction when connecting to the Internet from the tablet.

Return to the window initial settings router. Find a string called "Chanel" and change its meaning.

Try to try all values: select one of the channel modes, save the settings. Restart the tablet and router.

Try to connect again. Do so until you try on all available channel setup modes, which are presented in the router control window.

The automatic mode allows the router will automatically determine the most appropriate channel to establish communication with the subscriber device.

If the network does not work anyway, try to make a hard reset of your tablet - that is, return to the factory settings.

Perhaps there were problems in software Android devices. You can reset the parameters in the tablet settings menu.

The connection mode is incorrectly set.

If everyone previous methods The settings did not help you solve the problem with the connection of the tablet and the router, you should try the last of possible methods Solving the problem, which is likely to return to your device with the ability to connect to the router.

Perhaps the tablet and router operate with different versions wireless communication.

The tablet may simply not see or not support the version used by the router, so it does not connect to the Internet.

There are several options for compound modes: 802.11n, 802.11b, 802.11g. Go to the router settings and check the connections mode used.

Change it to any other. Restart all devices and try to connect again.

Thus, try the performance of all available versions of the channels.

Perform all the actions proposed in the article are necessary alternately, since all the problems are a consequence of each other.

All instructions described in the article will help you solve the problem of connecting and improve the quality of the connection with the Internet.

What to do if Wi-Fi is connected but the Internet does not work on Android

What if the tablet does not connect to WiFi - instructions with examples

More and more tablets are equipped with GSM or 3G modules, getting the opportunity to go to the network always and everywhere, and not only in the Wi-Fi area. However, with the appearance in tablet computers SIM card connections arose and pretty typical problem: The tablet does not see the SIM card.

When PO is guilty

Gadget software can also be the cause of the absence of the Internet. For example, if after the network suddenly disappeared, then, with a high probability, the reason was exactly the downloaded program. Try it to simply remove it.

And sometimes everything is fault by the user's inattention: accidentally activated the "airplane" or "autonomous" mode. In this case, it is necessary to check in the device settings that mobile networks are enabled and data transmission is allowed. Look there if the priority is not specified: in this case, it may not work mobile InternetDespite the defined card.

Another reason may fail system firmware. In this case, it will probably help or, in more severe cases, hard reset (remember that full reset Custom settings will be lost all information on the tablet, so it is pre-made a backup).

A common situation among when the device sees a SIM card, but it does not connect to the mobile network. Most likely in the settings mobile networks Parameters for native Chinese operators are exhibited. You must specify your mobile operator Or, if it is not in the list and is not when searching, manually set the parameters of the APN and the others you need to connect (you can find on the operator's website, in the communication salon or by calling technical support).

Let's sum up

So what to do if the tablet writes "no SIM card"? Here is a brief algorithm:

• check if the mode "in an airplane" or "autonomous" is not activated;
• if the Internet stopped working after installing new applications, remove them;
• check mobile network settings;
• check the SIM card on another device (tablet or smartphone);
• if everything is fine with the card, check the SIM reader connector using another SIM card (preferably another operator) -, attribute the tablet in service center To replace slot and loop;
• if the connector works and sees a map of another operator, replace its SIM in the communication salon;
• if the network does not appear with a new card, make a hard reset or;
• if all of the above did not help - direct road to service.

We hope that thanks to these advice, you will no longer have to confuse the back of the back when you are disconnected and you can solve the problem in most cases.

Technologies do not stand still. Mobile devices with which you can easily and quickly go online, are an integral part of each modern person. But what is a tablet without Wi-Fi? Just a piece of plastic and metal. Unfortunately, it often happens that the tablet does not see Wi-Fi. Next, we will look at why it can occur and how to eliminate such problems.

To begin with, it is worth understanding that Wi-Fi technology has different standards and protocols. That is, today there are many different versions Wi-Fi. However, only three standards are used in everyday life:

1. 802.11b is the oldest standard that works at a frequency of 2.4 GHz and has a maximum throughput up to 11 Mbps.
2. 802.11g - standard that was approved in 2003. Allows you to reach data rates up to 54 Mbps. Works at a frequency of 2.4 GHz.
3. 802.11n - the most fast version of the wireless communication, which allows you to achieve speed up to 300 Mbps. This standard operates at a frequency of 5 GHz.

As you can see, some of the standards work at different frequencies. This means that one of the reasons why the tablet does not see Wi-Fi, it can be in terms of frequencies. That is, if the router only works at 5 GHz frequency, and the tablet supports only 802.11b or G (2.4 GHz) mode, it is not surprising that the gadget cannot see the access point. Here you can already do nothing. Just when buying a tablet, specify its specifications.

It should be noted that many modern routers can work in mixed mode. That is, in the Wi-Fi settings in the router, you can select the 802.11bn mode. This means that the access point will hand out the network immediately at two frequencies, so old, and new mobile devices can be connected to it.

Weak signal

Don't forget that different tablets, like routers, have different antennas. Access point may have a weak antenna, because of which it can cover a rather small area. At the same time, some tablets, by virtue of the characteristics of their design, may have a weak antenna, which is muted by the metal case, which is why the reception will be very weak.

If, for example, a laptop antenna passes around the entire screen, then, of course, the signal level will be very strong. But if an antenna itself is much smaller in the tablet, and even closed with a metal cover, the reception signal will be insufficient. This is another reason why the tablet does not find the Wi-Fi network.

In this case, you should come closer to the router (come closely) and check if the tablet detects this access point. If detects, the problem is in a weak antenna. In this case, you can try to strengthen the antenna. But to do it you will be at your own risk, since not all the ways are simple and safe.

The problem can fade in another. In this case, the source of the difficulty can be both the router itself and the access point to which he tries to connect.

Why Android does not see Wi-Fi Network: Video

How to determine the problem

Often the tablet does not see Wi-Fi by the fault of the access point itself. One of the reasons was described above (the difference in supported frequencies). But sometimes in order to protect your home network, the owners hide the access point. Therefore, first of all, go to the router parameters and check whether the wireless mode is enabled and the network is hidden. All this is checked in Wi-Fi settings in the router.

If you remove a tick from the first line ("Enable Wireless Broadcast"), then the router will not distribute the network at all. If you remove a tick from the second line ("Enable SSID broadcasting"), the network will be hidden. That is, Wi-Fi will be distributed, but the devices will not see the network name. To such a network, you need to connect to manual mode.

If everything is turned on in the router parameters, it is worth checking if the tablet can see at least one network at all. This is done elementary. Just go to visit friends or in a cafe that has Wi-Fi, and so on. If your tablet sees other networks, then the problem is in your router. If the tablet does not find Wi-Fi network at all anywhere, then the problem is in the tablet.

Solving problems on the side of the router

Articles on the topic

The basic settings of the Wi-Fi Router we have already considered higher. That is, you check which Wi-Fi mode uses a router, and whether wireless broadcast is included, and whether the network is not hidden. If all these parameters are in order, then you can not configure anything else. In this case, you should restart the access point. Just disconnect the router from the outlet for 7-10 minutes, then turn on again.

If after that, still does not see the tablet wi-Fi networkYou should do to the factory parameters. If it does not help, you will have to update according to, since, most likely, some kind of failure in the system has occurred. Instructions for updating software, like the firmware itself, you can find on the official website of the router manufacturer. If even the software update does not help, you will have to buy new router. When you choose, pay attention to which modes and Wi-Fi standards support the access point.

Problem on the side of the tablet

If you have determined that the problem lies in exactly the tablet, that is, it does not see any network at all and does not go online even in close proximity to access points, there are several options here.

First of all, you should simply restart the device. The fact is that due to the accumulated cache (garbage), the tablet may not include a wireless adapter at all, which is why the search for networks does not even start. That is, the tablet does not catch Wi-Fi. The reboot resets the cache and restores minor failures in the system.

If this does not help, then you should move to more cardinal measures. Immediately it is worth saying that the Android system is arranged in such a way that there are no settings like on a PC. You cannot reinstall drivers for Wi-Fi-adapter, reset network settings or configure a network adapter. Connecting to networks occurs automatically. Therefore, if nothing of the above helps, you will have to relieve the factory parameters.

Another reason why does not catch Wi-Fi on the tablet, it may be that the antenna terminal moved away from the fall (probably there is no such tablet, which never fell). Also, contacts could oxidize due to high humidity or if the device was disassembled to repair, then when assembling the wizard, the wizard could have forgotten to connect the antenna. In this case, you need to disassemble the gadget: check if the antenna is connected and clear the contacts.

Of course, such reasons arise extremely rarely, but still they should be considered. Also, do not forget that sometimes due to intensive work, the network adapter can simply burn. You can't check this at home, and without such an adapter, the tablet, it goes without saying, will not be able to go online. Therefore, if you tried all the available measures, and nothing helped to correct the problem, it's time to carry your gadget for repair.

How to configure Wi-Fi on the tablet: video

Thanks to the growing speed, more and more tablets are equipped with GSM or 3G modules, getting the opportunity to enter the network always and everywhere, and not only in the Wi-Fi area. However, with the appearance in tablet computers, the connectors for SIM cards originated and a fairly typical problem: the tablet does not see the SIM card.

When PO is guilty

Gadget software can also be the cause of the absence of the Internet. For example, if after the network suddenly disappeared, then, with a high probability, the reason was exactly the downloaded program. Try it to simply remove it.

And sometimes everything is fault by the user's inattention: accidentally activated the "airplane" or "autonomous" mode. In this case, it is necessary to check in the device settings that mobile networks are enabled and data transmission is allowed. There see if the priority is not specified: in this case, the mobile Internet may not work, despite the defined card.

Another reason may be a system firmware failure. In this case, it will probably help or, in more severe cases, hard reset (remember that with full reset of user settings, all information on the tablet will be lost, so it is pre-made a backup).

A common situation among when the device sees a SIM card, but it does not connect to the mobile network. Most likely, parameters for native Chinese operators are set in the settings of mobile networks. You must specify your mobile operator there or if it is missing in the list and is not when searching, manually set the parameters of the APN and the others you need to connect (you can find on the operator's website, in the communication salon or by calling technical support).

Let's sum up

So what to do if the tablet writes "no SIM card"? Here is a brief algorithm:

• check if the mode "in an airplane" or "autonomous" is not activated;
• if the Internet stopped working after installing new applications, remove them;
• check mobile network settings;
• check the SIM card on another device (tablet or smartphone);
• if everything is fine with the card, check the SIM reader connector using another SIM card (preferably another operator) -, attribute the tablet to the service center to replace the slot and the plume;
• if the connector works and sees a map of another operator, replace its SIM in the communication salon;
• if the network does not appear with a new card, make a hard reset or;
• if all of the above did not help - direct road to service.

We hope that thanks to these advice, you will no longer have to confuse the back of the back when you are disconnected and you can solve the problem in most cases.

After purchasing the tablet, you will most likely want to use the wireless link. Often, users find themselves in a situation where the device does not see the network or gives a number of errors when connected. In this article, we will consider the most common problems that arise when entering the Internet and ways to solve them.

Why the tablet does not connect to the wireless network

1. Introduction of the wrong password

The most common cause of wireless Internet utilization on the tablet. Most often it occurs if the user has changed the password, and the Android device has never been connected to it. Enter new password And check if the device connects to the Internet.

2. Viruses

Sometimes the reason for which the device does not connect to the Internet may be the impact of malicious programs. To eliminate this problem, you must scan antivirus gadget.

3. Failure to power

For inexpensive routers, unstable work is characteristic. Racing in voltage can lead to the fact that the tablet does not see the network. To solve the problem, restart the router, disconnecting it from voltage for 2-3 minutes. Then turn on again. Sometimes a reboot must be done several times.

4. Incorrect encryption type

To check the encryption type, go to the router settings. To do this in the browser's address bar, enter the IP address of the router. This data can be viewed on the device sticker or in the instructions. In the tab that opens, select "Extended Settings". Then in the "Wi-Fi" section, click Safety Settings. To see the encryption type, go to the "Network Authentication" menu. From the proposed options, select WPA-PSK \\ WPA2-PSK2 Mixed. Restart the router. 5. Incorrect time settings and date

In some cases, the tablet does not connect to the wireless network due to incorrect dates and time values. After fixing these parameters, to resume the correct operation of the network.

6. Checking MAC-filter mode

Another reason for which the user on the tablet does not see Wi-Fi, can be changes to the filtering settings of MAC addresses. To exclude this option in the router parameters in the "Wi-Fi" section, go to the MAS-Filter item. Check which mode is selected. The following values \u200b\u200bare possible:

• Disabled - by default, no restrictions for MAC addresses.
• Allow - access to the wireless network is allowed only to those devices whose MAC addresses are written on the corresponding tab. Other devices access to the Internet is prohibited.

Prohibit - there is a list of MAC addresses, which are limited access to the Internet. If the router sees the forbidden MAC address, it closes the device to Wi-Fi for this device.

If you select "Allow" or "prohibit" in the router settings, check whether access to the MAC address of your device to the wireless network is open. Either change the mode to "disabled". After these manipulations, check how the gadget connects to the network.

7. Diagnosis of channels

If the tablet sees the network, but does not connect to it, check the correspondence of the channels. This problem occurs when the signals of two routers running on the same channel intersect. There are interference that closing access to the wireless network.

Look on your tablet, is there any other wireless networks. If your neighbors have Wi-Fi, then perhaps your routers work at one frequency.

To change the channel in the router settings, go to the "Wi-Fi" section to the "Basic Settings" tab. Find the "Channel" string, try to select another value.

Restart the router.

If the settings have a channel in Auto mode (AUTO), the router will search for an affordable free channel and use it. Therefore, in most cases it is recommended to use this mode.

8. Changing Wi-Fi version

The reason why the tablet does not see the wireless network, it may be that it does not support the wireless version, which is installed in the router settings. On the Wi-Fi tab, go to "Basic Settings". In the "Wireless Mode" string, slide 802.11b \\ g \\ Mixed. In this mode, the router provides Internet access for all types of devices.

What if the tablet sees the network and connects, but the connection is unstable

• Try connecting the device to another router and check whether the connection is stable. If the connection is stable, then the problem is in the home router.
• If during the output of the Internet on the tablet, charging was taken, and it is connected to the power supply, check the connection when the adapter is turned off. The malfunction of the power supply can lead to wireless communications problems.

If nothing helped look at this video and repeat:

If you have taken advantage of the following advice, but the device still does not see the network, refer to the specialists. It may be necessary to reflash the tablet or router.

A modern tablet is difficult to imagine without Wi-Fi module. However, sometimes the user faces a problem in which the tablet does not see Wi-Fi. What could be the causes?

1. The first reason that immediately comes to mind - weak signal because of constructive features Gadget. In contrast to the laptop antenna, the Wi-Fi-antenna of the tablet has smaller sizes and can be covered with a metal cover, which can significantly weaken the received signal.

Decision: Place the tablet in close proximity to the router or try to enhance the signal.

Search Wi-Fi in iPad

2. The operation of the router at a frequency not supported by the tablet may cause the tablet not see the Wi-Fi access point. There are three main standards: 802.11b, 802.11g and 802.11n. Despite the fact that many routers are capable of working in a mixed mode, providing data transmission at all possible frequencies, some network devices support only one data transfer standard. Let's say 5 GHz. And the tablet works only by 2.4 GHz (802.11b or 802.11g). Of course, the tablet will never see Wi-Fi.

Decision: To find out in detail the characteristics of the tablet before buying, make sure that the router and the tablet in terms of supported Wi-Fi protocols are compatible.

3. The reason may also conclude that the access point was hidden by its owner.

Decision: Change the router settings so that the access point is no longer hidden. At the same time it is worth checking whether the wireless mode is enabled. Here can act general rule. In the settings of many routers there is an "Enable SSID broadcast". If you remove a tick with this setting, the network will become hidden. Opposite the setup "Enable Wireless Broadcast" should also stand a daw - in this case the wireless connection will be allowed as such.

4. The reason may come in the router itself. Here are several ways to solve the problem.

Cause

Decision №1: Reload the router.

Decision number 2.: Rollback of the network device to the factory settings.

Decision number 3.: reflash the router by downloading last version Firmware from the official content of the device manufacturer.

Decision number 4.: Buy a new router, if nothing about the above helped.

5. Cause of the fact that the planets does not see Wi-Fi can also walk in the tablet. Here you can also consistently try to resolve it in several ways.

Cause: hanging the router or failure in its work.

Decision №1: Reload the gadget, with the result that the cache will clear and disappear some errors in the system.

Decision number 2.: Reset the gadget settings to factory. This measure is cardinal, but without it, it happens, not to do. The fact is that, unlike Windows, with its flexible network settingsThe Android operating system will not allow reinstalling drivers for a Wi-Fi module, reset network settings or configure the network adapter. Android devices, as a rule, are connected to the access point in automatic mode.

Other reasons: Routher malfunctions as a result of physical impact, namely:

1. Antenna failure due to the fall of the gadget.
2. The oxidation of its contacts in high humidity conditions.
3. The negligence of the wizard during repair work when he forgets to connect the antenna.

Decision: Open the tablet case and:

1. Make sure the antenna is connected.
2. If there are traces of the oxidation of contacts, clean them.

Cause: The failure of the network adapter of the tablet as a result of its burnout due to overloads in its operation.

Decision: Maybe only one thing is to carry the tablet to repair and continue to prevent the device overloads.

How to determine the problem in the router or tablet?

If your tablet does not see Wi-Fi in the home network, then check whether your tablet connects to the network elsewhere, for example, to any free access point on the street or in a cafe. You can also check this away from a friend or girlfriend who have Wi-Fi.

Hello everyone!

I analyzed a little comments here, which visitors left on the site, checked requests and realized that there is a very common problem with connecting to Wi-Fi, which I have not written yet. But a lot of comments are left on the site with a request to help solve this problem. I advised something there, but I don't know if my tips helped you (Rarely who will write about the results 🙁).

And yesterday, Roman (Thank you good man 🙂) The article left a comment in which he shared information as he solved the problem "Saved, WPA \\ WPA2 protection". This comment helped me a little orient in the problem, and I decided to collect all the advice on solving this error, in one article.

The essence of the problem

When connecting a phone, or tablet (most likely on Android), to the home network, or somewhere in the cafe, there is an inscription near the network name "Saved, WPA \\ WPA2 protection". And nothing more happens. If you click on this network and choose To plug, nothing happens. What this error looks like, you can look at the screenshot above.

I specifically provoked this problem on my Wi-Fi router ASUS RT-N13U and tried to connect hTC phone ONE V (Android 4.0). So I got this inscription "Saved, WPA \\ WPA2 protection". Moreover, everything turned out the first time. How? Yes, very simple. In my router settings, the "wireless network mode" was in AUTO mode, and I installed N ONLY. Saved the settings, turned off the phone from Wi-Fi, but it was no longer possible to connect.

The main causes of the error "Saved, WPA protection" WPA "WPA2"

Friends, I can't definitely assert and give advice that will be one hundred percent workers, I hope you understand. All devices are different, all the settings are different and many more nuances.

But I will try to assemble the reasons for me and how to solve them, through which such a problem with connecting to a wireless network may appear.

If when connected to a wireless network, you saw the inscription "Saved, WPA \\ WPA2 protection" (maybe a little different)then you should check these settings (I advise you to check in the same order):

To begin with, just restart the router.

Several times already noticed such a problem: the Internet on the phone simply stops working, but the connection is also a good network. Turn off and turn on the Wi-Fi on the phone, and the network is no longer connected, writes "saved, WPA2 protection". It helps only reboot the router.

1. Set the right region in the router settings
2. Check the password correctly from Wi-Fi network
3. Check (Edit) Wireless Mode in Routher Settings
4. Check (change) type encryption and security type, change password in router settings
5. To experiment with the change of the channel on which your wireless network works.
6. Try to change the width of the channel.

And now more on all items

Expose the right region in the router settings

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

I will show you on the example of TP-LINK how to change the region. If you have a router of another company, then these settings are most likely changing on the same page where the name and other wireless network settings are set.

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

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

Check the password and connect again

You may just specify the password wrong (True, then most likely there will be a constant connection, in a circle. But you need to check), And before climbing the router settings, I advise you to check it out.

You ask, and how can I write a password, 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 the password from Wi-Fi. Just make sure it is correct. If you forgot, see the password in the router settings, or on the connected computer (if there are such). Read more in the article.

Checking the wireless network mode

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

Mode of operation - these are incomprehensible letters b / g / nThat you probably have already noticed in the router settings. Try to experiment with changing the mode. Do not forget to restart the router after each change and turn off / enable Wi-Fi on the phone (tablet).

So I installed N ONLY instead of AUTO and jumped the mistake. And if you already have N ONLY in the settings? So you have problems.

Change the type of encryption / security, password

It may be that your device simply does not like the type of security, or encryption that the router uses. Or do not like the password.

I advise you to set such values:

WPA / WPA2 - Personal (Recommended)

Version: WPA-PSK

Encryption: AES.

PSK password (key) - not less than eight characters and only numbers.

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

Attention! After changing the password, or other security settings, problems can be connected to other devices that have already been connected to this network. (Computers, laptops, TVs).

Experiment with a channel on which Wi-Fi network works

Unlikely, of course, but maybe. About what is a wireless network channel, how to change it and why, I wrote in the article -.

Try to experiment, but suddenly helps.

Channel width

There is such an item in setting up Wi-Fi Router, as Channel width. If you, for example, TP-LINK and menus in English, is called it Channel Width..

There you can choose several options: auto, 20mhz and 40mhz - depends on the router. Try to install first AUTO. (or in ASUS 20MHz / 40MHz), if it does not help, then separately.

Where to change the width of the channel?

Go to the router settings ( address 192.168.1.1, or 192.168.0.1, enter a login / password - we 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 settingsPoint Channel Width..

Do not forget to save the settings and restart the router.

Afterword

I wrote everything like everyone wanted. I really hope that my tips will help you. You get rid of this problem and make friends your phone, or tablet with Wi-Fi Router 🙂 .

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

Good luck!

The phone does not connect (tablet) to Wi-Fi, writes "Saved, WPA protection \\ WPA2" Updated: February 7, 2018 by the author: admin.

In this article we will talk about such a common problem what to do if the tablet does not connect to the wireless WiFi network. This is up to date the topic today, as the tablets are enjoyable distribution worldwide. In addition, problems with connecting to wireless networks appear quite often and not everyone is able to solve them independently.

So, speaking of a wireless network, it is worth understanding that we are talking About WiFi Router or other access point. It is worth noting that for security purposes, such connections require key administration. This means that the first thing if the WiFi network does not connect on the tablet, you should check the correctness of the password.

Why the tablet does not connect to wifi

As mentioned above, the most common error is an incorrectly entered password.

However, other problems associated directly with wireless equipment and its settings are found. These include the following:

• Mac filter is installed in the router settings.
• Failures in the router.
• Non-compliance of encryption types.
• Channel inconsistencies.

It is worth noting that there is nothing to customize anything in the tablet. All that can affect the connection is concluded in the router settings. That we will go to troubleshoot. And first of all, it should be paid to the fact that budget routers, such as TP-Link, D-Link. Asus, Zyxel and so on, do not differ in high stability of work. They have a tendency to hang.

This can occur for many reasons, for example, due to interruptions in the power supply network, a strong load (if you swing large amounts of information at high speed), as a result of connecting a large number of subscribers and so on. In any case, you should restart the router. How it's done. Everything is simple. Disconnect the device from the power supply and wait 7-10 minutes, then turn it on again.

Checking the encryption type

If the tablet does not connect to wiFi networks And writes "saved", then this indicates the inconsistency of encryption types. First of all, you should know that modern WiFi devices support the type of encryption WPA-PSKWPA2-PSK2 Mixed. If you select another mode on the router, then the tablet is simply and, accordingly, connect. In other words, the tablet sees WiFi wireless network but does not connect to it.

So, we need to enter the router settings. To do this, connect to it using a laptop (via WiFi or through a cable). Next, open any browser and in the address bar We write an IP router. The desired data is available on the device itself or in the instructions. If you do not have a manual, there are no data on the router housing, then open the command prompt. To do this, simultaneously press windows keys + R, in the window that appears, write CMD and press "ENTER".

In the opened menu, write the ipconfig command and press "ENTER". Now you need to find the "Main Gateway" string. This is the data we need.

As a rule, it is 192.168.0.1, but depending on the router model, these values \u200b\u200bmay differ. So, we prescribe the received data in the browser, after which the system will ask you to enter a login and password. We write admin, admin, respectively.

So we got into the router settings menu. It is worth noting that depending on the device model, the interface may differ. Also differences may be in the names of some sections. Consider next steps Using the example of the D-Linkdir-615 router.

In the router parameters at the bottom of the screen, click the "Advanced Settings" button. Find a section called WiFi. Here you click "Security Settings". Here the first line "Network Authentication" is a type of encryption. Select from the proposed WPA-PSKWPA2-PSK2 Mixed options and apply the changes. After that restart the router.

Often, a similar error occurs and when correctly installed type authentication. In this case, you will help reboot the router. As mentioned above, budget models do not differ in stability in the work.

Check MAC filter

The answer to the question why the WiFi network does not connect on the tablet lies in the filtering settings of Mc addresses. The fact is that a special function is included to enhance protection, which defines the physical address of the computer, opening or closing it access. To check this, you should return to the router settings. In the WiFi section, select Mac Filter.

In order for you, you do not have any problems in the future, you should turn off the filtering.

But if you do not want to do this, we do the following. In the beginning we look at what kind of mode is selected:

• Allow - the router allows access to only the specified devices.
• To prohibit - the router blocks access to the network specified tablets.

Now it remains only to learn the physical address of your tablet and check if it is in the list and, if necessary, add or delete it.

Check channels

If you have turned off the filtering, and the tablet still sees the WiFi network, but does not connect to it, then go to the next step. This problem often arises due to channel inconsistencies. So let's return to the router settings and try to change them.

To do this, return to main page Access point parameters and in WiFi section Select "Basic Settings". Here we need to find the line "Channel". Try to change it on some other. It should be noted that it is recommended to install the "Auto" mode. Thanks to this, the router will automatically use the most appropriate channel.

What if you tried all the above actions, but still can't connect the tablet to the WiFi network? Try to restart not only the access point, but also the tablet itself. Quite often there are various failures and in mobile device. After rebooting, try to connect again.

Wireless mode

Do not forget about the versions of the wireless communication. Very often, the report on the question why the tablet does not connect to the WiFi network, is the fact that it simply does not support the version of the wireless communication that is installed on the router. The fact is that today there are several versions of Wi-Fi Communications:

• 802.11n.
• 802.11g.
• 802.11b.

At the same time, as a rule, the router supports all these standards, which cannot be said about the tablet. Therefore, let's go back in the router settings menu and check which mode is set. Open advanced settings. Next, in the WiFi section, select "Basic Settings". In the "Wireless Mode" row, select 802.11 b / g / n Mixed.
