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 from 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.

Sometimes a problem arises such as the inability of Android to connect to a WI-FI wireless access point. How to solve this problem? Find out in this article!

And so you came to visit or are in a cafe, or perhaps you bought a new router and configured it to distribute the Internet via WI-FI, but your Android smartphone or tablet does not want to connect to the network or does not even see it! Don't worry, there is a way out!

Possible problems and solutions

1. If Android sees the network, but cannot connect to it, make sure that you enter correct password!

2. If Android sees the network, but cannot connect to it - perhaps Android does not support protection type installed in the router, change the type of protection (read router settings below)

3. If Android does not see the network, make sure that WI-FI network is functioning, reboot the router (on/off)

4. If Android does not see the network, perhaps Android does not support WI-FI standard

5. If Android sees the network, but cannot connect to it, restart Android and the router

6. If Android sees the network, but cannot connect to it, install a special application on the device from the Google Play store - Wi-Fi Fixer. After installation, restart Android and if the Wi-Fi Fixer application does not start, launch it yourself, then try connecting to the access point (you do not need to enter any settings into the application)

7. If Android sees the network, but cannot connect to it, although the password is entered correctly - perhaps Android does not support WI-FI standard on which the router is running (read below for setting up the router)

8. If you have custom firmware installed on your Android tablet or smartphone, then this may be the problem, reinstall it to the official one

9. The opposite advice to the previous one, if the official firmware is installed, then you should change it to custom (for example, CyanogenMod), since it is possible that the WI-FI driver has already been updated

12. Perhaps you have a Dlink router?

Setting up the router

First of all, you need to get into the router settings.

Go to router settings

To do this, it is better to use a computer, as well as the FireFox or Internet Explorer browser. Let's open one of them. Next, you need to find out the entry address, which can be found by knowing the network gateway.

This address must be entered into the address bar and go. Next, you will be asked to enter your username and password, which, as often happens, is located on the bottom of the router case.

Setting up WI-FI

1. First of all, if Android does not connect, you should switch the WI-FI channel to auto

2. Change the WI-FI transmission mode standard to Mix or G only

3. It is also worth checking the number of allowed device connections to the wireless network

4. Try changing the network security method, change the encryption type from open to WPA

5. Another point worth paying attention to is the enabled DHCP server, which allows you to give internal IP addresses on the network. If you disable the DHCP server, you may experience problems connecting to WI-FI and not only with Android devices!

6. Make sure that the MAC filter is not installed in the settings!

A MAC address is a personal (individual) serial number of a network device.

Depending on the router, there may be white lists of MAC addresses or black lists.

Blacklisted- devices that are prohibited from entering the network, but other devices can.

White list- only those devices that are in this list and no other devices can connect.

To find out the personal MAC address of Android you need to go to

Settings -> About smartphone (Tablet) -> General information

Try disabling the MAC address filter to resolve the connection problem.

Users modern smartphones They know that you can fully use all the functions of the device only if you are connected to high-speed Internet. Despite the development of mobile 3G and 4G Internet technologies, many people prefer to use it to access the network if possible. Wi-Fi connection. At the same time, situations often arise when the phone does not see Wi-Fi. We will look at why this happens and what to do to fix the problem in this article. But first, let's briefly dwell on the extremely interesting model a smartphone with which you will definitely never have problems accessing the Internet. This .

Briefly about Wileyfox smartphones

We decided to pay attention to this young promising brand for a number of reasons. The company entered the mobile gadgets market in October 2015. Thanks to the significant advantages that each model from the Wileyfox smartphone line has, the company managed to quickly gain not only the trust of users, but also attract interest from experts. These are functions and features such as:

Work with two SIM cards;
Support mobile networks 4G LTE data transmission;
Stylish original design and high-quality materials used in the manufacture of the case;
Powerful hardware components and high quality components and elements;
Loyal pricing policy.

The new brand was noticed and received support both in the market and among experts. The most important achievements of the company:

In December 2015, Forbes magazine experts named the Wileyfox Swift smartphone of the year;
The brand won first place at the British Mobile News Awards 2016 in the manufacturer of the year category;
In October 2016, the authoritative online publication Hi-Tech Mail.ru, summing up the results, awarded the Wileyfox Spark+ model first place in the category “ Best smartphone up to 10,000 rubles.”

The device attracts attention with its original design and powerful hardware. The stylish modern model has a fingerprint scanner and NFC module. Traditionally for modern smartphones, Wileyfox Swift 2 has Glonass, GPS and Assisted GPS navigation modules on board. High speed and performance are provided by a powerful 8-core Qualcomm processor Snapdragon 430 MSM8937 with an operating frequency of 1.4 GHz.

The model is equipped with 2 GB of RAM and 32 GB of internal memory. It is possible to install a microSDXC card up to 64 GB. The device received a 16-megapixel main camera and an 8-megapixel front camera module.

Most often the problem is connecting a smartphone to a wireless Wi-Fi Internet appears if the distributing equipment is not a router, but a laptop. It is worth noting that, in fact, it does not matter which device “distributes” access. The connection principle does not change. The network is exactly the same as from the most ordinary router.

The only differences are that the router has a wider range of settings and parameters. Most often, the phone does not see the Wi-Fi network created on the laptop due to the fact that it was not organized correctly. Yes, when creating Wi-Fi The network on the laptop has the ability to connect like “computer to computer”. Your smartphone simply will not be able to recognize this type of network, since it is designed only to work with computers and laptops.

But if the network is organized by a router, you first need to look at its parameters, since they are configured in the router. The fact is that operating system The Android on which your smartphone runs is designed with the expectation that the user will have to configure almost nothing. And if your phone doesn't see Wi-Fi router, then most likely the problem is in the router or laptop that distributes the Internet.

There can be only four reasons why the phone does not see Wi-Fi:

Error when entering the network password (security key);
Incorrect router (router) settings;
Router malfunction (software freeze);
Error in Android OS.

The last reason is extremely rare, but you shouldn’t completely discount it. Now let's look at each of these reasons in more detail.

Often the phone cannot connect to wireless wifi network because you are entering the security key incorrectly. To ensure that all characters are entered correctly, check the “Show password” box when entering it. Check carefully that each character is entered correctly, taking into account the case and language of the key input. You are probably entering the wrong password simply because you forgot it. In this case, you need to connect to the router.

This can only be done through a desktop computer or laptop. To enter the router security settings, you need to enter the IP address of your router in the address bar on your computer. This information is contained in the user manual for the router and on its case. But even if you don’t know the address, the situation is not hopeless.

Just run command line and run the IPCONFIG command, after which you will receive all the information about the connections. In the window, find the line “Default gateway” - this is where the address needed to connect to the router is displayed. When you access it in the address bar of your browser, you will need to log in. By default, the login and password are set to “admin”.

After you connect to the router's management interface, you need to find the security settings menu. Depending on the router model, this menu may be in different places, but most often it is located in the advanced settings. In the “Encryption key” line you will find the password to enter the wireless network. It is this that must be entered when connecting the smartphone to Wi-Fi.

Router settings

The inability of a mobile gadget to connect to a wireless network can also be explained by errors in the router settings. The problem may be that modern routers use DHCP technology, which means that connection information is sent to the smartphone automatically. This is what everyone is counting on Android devices- they are waiting for an IP address to connect. But if the address is not sent, connection becomes impossible.

The problem may be that this function disabled on the router. To check this and enable it, you also need to go into your router settings. The option we need is in the “LAN” section. In this section you need to enable DHCP by selecting the “Allow” option. After this, you need to reboot the router and try to connect to the network using your phone.

The phone may not see or not connect to the network because the router is frozen. Despite this failure, your laptop or computer can continue to work and connect to the Internet without any problems. A router malfunction may simply result in DHCP being stuck. As a result, it turns out that previously connected devices to the router work normally, but new ones cannot connect. Similar problems may occur with other router options.

To eliminate this possibility and fix the problem, just reboot the router. To do this, you don’t need to go into its settings, and you don’t even need a laptop or computer. Just turn off the power to the router and turn it on again after a few minutes. After that, try again to connect to the network from your smartphone. It is worth noting that such problems are typical not only for budget routers. It’s just that on expensive models such errors occur less frequently.

Android OS malfunction

If, after you have checked all the probable reasons for the failure of the router, but you cannot connect to the network, there is one last option left for why the phone does not see Wi-Fi - a malfunction in the operating system of the smartphone itself. IN mobile gadgets Wireless adapters are installed that may display errors or freeze. In the case of a telephone, no settings are provided for the user. Just try restarting your smartphone.

Conclusion

If, after doing all the above operations, you still cannot connect to the network with your phone, the problem probably lies deeper. Try connecting to a different wireless network. If you are also plagued by failure, you need to seek help from service center for repairing your phone model.

This article will talk about typical problems when connecting your phone to a wireless Wi-Fi network, the most common of which are Android stuck on “obtaining an IP address” or an authentication error when connecting. Less common, but it occurs when your Android phone or iPhone simply cannot be seen Wi-Fi network.

IN step by step instructions The following variants of the problem will be considered in order and what to do in each case.

Authentication error (or phone says Saved WPA/WPA2)
Endlessly obtaining an IP address on Android
The phone does not see the Wi-Fi network

Wi-Fi authentication error on Android

If your phone or Android tablet when connecting to Wi-Fi, it reports “authentication error” or writes “Authentication” for some time, after which it still does not connect to the wireless network (when Android writes Saved WPA/WPA2 - this is usually the same situation), then in most cases the problem is in the Wi-Fi password, and the problem can occur even when you enter it correctly (but, of course, this is what you should check first, the article can help with this, you can also just look at the router settings).

But it’s not always a matter of incorrect input: it happens that you are guaranteed to enter the password correctly, but an authentication error still occurs.

The first thing you should try here:

Delete the Wi-Fi network (forget it) in the phone settings, try connecting to it again by entering the password.
Reboot the router (unplug it and plug it back in).

If none of this helps, go to the router settings (any of the instructions for setting up a router on this site will help with this, they all start with how to go into the router settings), and then into the Wi-Fi network settings and try the following ( after each change, save the settings, delete the previously saved network on the phone and try to connect again):

If even these points do not help, make sure once again that in the Wi-Fi network security settings in the router settings, WPA/WPA2 (Personal) authentication is set, and not some other type (this option should be supported on any Android phone). It also sometimes helps to change the network operating mode from b/g/n or auto to 802.11 n only or 802.11 b/g.

Android constantly writes Obtaining an IP address and does not connect to Wi-Fi

The second most common problem with connecting a phone (specifically Android) is endless attempts to connect with the text “Obtaining an IP address.”

What could be causing the situation:

The DHCP server is disabled in the router settings.
Just an Android glitch.

If you don’t know exactly about the first point, then first just reboot the router, perhaps this will solve the problem. If this does not help, then the following steps:

Check if DHCP is enabled on the router; if not, enable it.
If it is enabled, but still “Obtaining an IP address,” then try setting a static IP address on the phone.

And now more about how to do both.

To enable the DHCP server, you will need to go to the router settings (any setup instructions D-Link routers, Asus, TP-link, Zyxel begins with a description of how to enter its settings) and make sure that the DHCP server is enabled (as a rule, there should simply be such a checkmark): on almost all router models this option is located in the LAN or LAN (local area network):

On ASUS routers- LAN - DHCP server tab
On TP-Link routers - Additional settings- DHCP settings
On Zyxel routers Keenetic - In « home network» - Network organization, for the DHCP option enable “Server”. Or, on Keenetic Lite, in Home Network - Segments, check that DHCP is enabled.
On D-Link - in the “Network” or “LAN” section, the “DHCP Server” item or tab

The second option is to set a static IP address on Android, to do this:

Save the settings and try connecting to the Wi-Fi network from your phone again.

Android phone or iPhone does not see Wi-Fi network

If your phone does not see the desired Wi-Fi network, but sees other networks, then in most cases the problem is in the Wi-Fi channels used. The fact is that by default in the router settings in the wireless network parameters it is usually set to “Region: Russia” and channel: auto, which forces the router to select channels from 1 to 13. But: some devices do not support channels more than 10. (On this topic there is a separate instruction :)

Thus, the first thing you should try is to go into the router settings, go to the wireless network settings settings and change one of two things:

Region - set to USA, supported by almost all devices, only 10 channels.
Change the channel manually (set within 10).

After that, save the settings and check if your phone can see the network now. If this does not help solve the problem, then it makes sense to also try changing the channel width in the router settings, and for older phones, try also changing the network operating mode to 802.11 b/g.

Every user sooner or later is faced with the fact that for some reason Wi-Fi does not work on the phone. This article is intended to help identify the sources of these common problems and find the fastest and most effective method their elimination.

So, let's find out!

Malfunction wireless communication, as a rule, caused by several reasons:

Incorrect Wi-Fi settings.
Errors in the operation of the router itself.
Incorrect mobile device parameters.
Action malware or antivirus software.

Below we will look at each item in detail and formulate recommendations for troubleshooting. All of the following is true for Wi-Fi on Android phone, iOS, and for other operating systems.

Troubleshooting

You can cope with the problem only if you accurately determine its cause. To do this, you do not always need to contact specialists. Many errors that relate, for example, to wireless mode parameters, can be identified independently. If the Internet slows down or works slowly, this may be due to third-party factors: for example, network overload when many gadgets are connected to it. Sometimes slow Wi-Fi is a reason to check the computer itself or the communication line of your Internet provider.

Incorrect Wi-Fi setting

First of all, you should pay attention to how the point is configured Wi-Fi access. To do this, you need to access the router menu through a browser: but you will need to enter address bar a series of symbols, the combination of which is individual for each device. Usually this data is located on the back of the router, look for the Login and Password lines, they will be needed in the next step.

Enter your username and password. If you managed to gain access to the menu, first of all you should pay attention to the wireless mode parameters. There are a few simple options here:

Channel - Auto, but you can try setting a different channel.
Mode - 11 bg Mixed, but changing the parameter to 11 bg only can give a positive result.
Channel Width - auto.
The transmission speed, if any, is set to the maximum value.
Region has little effect, but theoretically it can be a source of malfunction.

If everything is configured correctly, but the Internet still does not function correctly, you should contact a service center or look for the problem elsewhere, for example, by contacting your ISP. The device may be technically faulty, so it is recommended to check it immediately after purchase.

Router settings

You should check whether it is possible to access the Internet at all. If she doesn't exist, what about personal computer, and from another device, it is advisable to check whether the router itself is turned on and whether it is working correctly. Indicators signal this.

The power indicator should be green. Next to it is a system indicator that should blink. The next indicator, WLAN, shows whether wireless is enabled on the router itself or in its menu. Next are numbered LAN ports, to one of which a cable must be connected. Ideally, it should also blink. After them usually comes WAN, the indication of which indicates that the router is connected to the Internet.

In some cases, reconnecting helps.

Incorrect time or date

Wi-Fi on mobile device may not function well due to such a small thing as an incorrect date - this is one of the first on the list of common causes of problems with the Internet. You just need to go to the time settings section and set the correct values. It is important to take into account the time zone correctly.

Wi-Fi password error

Other possible reason- password. If the phone connects to the hotspot automatically, this error occurs when the user changes the password. In other words, the password has been changed, but the gadget itself “does not know” about it and automatically enters the old one. The solution, again, is simple - create the connection again and enter the correct password.

Malware and antivirus programs

Viruses that the smartphone has “caught” on the network can also interfere with the correct operation of Wi-Fi. If you suspect an infection, it would be advisable to install antivirus program and conduct a check. There are many such programs, but they usually use established brands like Kaspersky and ESET Nod.

The other side of the coin: antivirus and other security programs, such as a firewall, can themselves be a source of problems. The antivirus creates a kind of “shield” to filter traffic, which sometimes affects communications. If after removing the anti-virus software the connection works correctly, in this case you will have to try another software or abandon it.

Software glitches

Many users experience wireless connection problems due to incorrect operation software. For example, when the user installs alternative firmware or makes any other interference with the factory characteristics of the software.

Problems with the Android system are also evidenced by other errors in the operation of the gadget - constant, systematic freezes, random shutdowns, and others.

In this situation, you can do a Hard Rest - it will return the system to factory settings.

If the problem is with the phone's firmware, this will help solve it. But you need to know that “non-native” firmware is not deleted in this way.

When the source of incorrect operation lies in the router, you often just need to reboot the router. This is not always easy to do, since some models are not equipped with an on/off button.

If the device itself does not have a reset function, you can simply unplug the cable for 10-30 seconds.

It can also be done through the device menu. The procedure for entering there is described above. This method This is relevant if it is difficult or impossible to get to the router itself. "Reboot" option in different models routers is located in different parts of the menu, but, as a rule, on the system settings tab.

If an error in Wi-Fi operation is due to failures in software, you can try rebooting the device. In addition to the standard “Restart”, there are several more radical and thorough methods:

Through the menu: “restore and reset”.
By entering the number *2767*3855#.
Through Recovery Mod - you can call it by holding down “Home”, “Power” and volume down at the same time. Next, select the “Wipe data” section.

Conclusion

Issues with the functioning of Wi-Fi, as a rule, can be resolved easily and without the involvement of specialists. But it is worth remembering that independent technical intervention can damage the machine to the point of complete loss of functionality. If connection difficulties are not resolved accessible ways, it is better to contact the service center.
