Wi-Fi is connected, but the Internet does not work on Android. Can't connect to my WiFi

Now, probably, you will not find users who have not heard and have never used Wi-Fi wireless Internet. It is the main source of connection to the World Wide Web for mobile devices. However, sometimes it happens that an Android phone or tablet does not want to receive Internet from a home router or any other wireless access point. Today we will try to figure out why this is happening and how to fix this problem.

This kind of behavior is not typical, and most of it is due to software problems: incorrect settings of the phone (tablet) or the router itself, as well as problems with the firmware of both. There may also be hardware incompatibility - this, alas, happens. Let's go in order.

Reason 1: Wrong dot password entered

The most common cause of problems with Wi-Fi, which is caused by banal inattention. As a rule, Android devices report that they cannot connect to the point if the password is entered incorrectly. It looks like this.

If you see a similar message, the algorithm of actions is as follows.

If the problem is still observed, proceed to the next steps.

Reason 2: Incorrectly configured type of protection in the router

Also a fairly common cause of Wi-Fi connection problems. This is especially true for older routers, which may not support certain types of secure connections. You can fix this problem like this.

Look in the router's user manual for the login address to the management web interface. If there is no manual, then, as a rule, there is a sticker with the specified address on the router itself. In most cases, it consists of numbers, and looks like this, for example.
192.168.*.*
Instead of symbols «*» there will be a number from 1 to 9.
Open a browser (any one will do) and enter the address that you learned in the address bar. Should load a page like this.

The login and password for the web interface in most cases is a word "admin". If it doesn’t fit, study the instructions and the router itself in more detail - the default login and password must be indicated there!
Once logged in, you will get something like this.

Next steps: find the Wi-Fi connection setting in the menu. It is usually called "Wireless LAN", Wi-Fi Settings, simply WLAN or, if the interface is Russified, "Wireless Network/Networks".

Click on it 1 time with the mouse.
A window similar to this will open.

Look for a setting in it that contains the word "Encryption" or "Encryption Type". As a rule, it is combined with a drop-down menu.

Select the protection type from this drop-down menu AES. Don't forget to save your changes.

You may also need to reboot your router. You can do this directly from the web interface.

A banal power off of the router for 10-20 seconds will also help.

If the reason for the problems with Wi-Fi was incorrect encryption, then the next attempt to connect the Android device to the hotspot should be successful.

Internet problems are always annoying. They can interfere with work or play, or limit other online experiences. If we are talking about connecting via a cable, there may not be so many possible causes of this problem.

The laptop detects an available wi-fi network, but does not connect

One fairly common network problem is when your computer sees a network available for connection, but for one reason or another cannot connect to it. This problem can occur for one of the following reasons:

a problem with the hardware drivers on the laptop - for this reason, the connection may not be performed or terminated immediately after a successful connection to the network;
communication interference - too many devices should not be connected to Wi-Fi, and it is also worth making sure that nothing can interfere with your laptop and router;
the password for connecting to this network was entered incorrectly - if you entered the security key incorrectly, the connection will not be completed;
network mismatch - if the connection settings on your computer and the network settings do not match, the connection will not be completed;
failure of the operating system - in case of some problems with the operating system, the connection will not be made correctly.

Solving problems with connecting to a wi-fi network

Let's take a look at the solution to each of the problems mentioned above in turn, and also study general recommendations for those who have encountered this problem in their system.

"Windows could not connect to Wi-Fi" error and how to solve it

When you try to connect, you may see the message "Windows could not connect to the Wi-Fi network." This error can have several causes. You can determine the source of the problem as follows:

Video: Fix Internet Connection Problems

Security key mismatch when connecting to a Wi-Fi network

The security key is the security code for your Wi-Fi network. The user independently sets it so that outsiders cannot connect to the network. And if you encounter an error about entering the wrong password, then it is likely that it was entered incorrectly. Do the following to make sure the situation is corrected:

Do not tell your security key to strangers - this will lead to additional connections, which in turn will slow down your Internet speed.

Stored network settings mismatch

After creating a new connection, you can often see an error with the text "The network settings saved on this computer do not match the requirements of this network." This problem often occurs after self-configuring the router. To correct this situation, all you need to do is delete the connection and then re-create it. This will update all settings and establish a connection again. This is done as follows:

Click on the Internet icon in the lower right corner with the right mouse button and select the "Network and Sharing Center" section.
Select "Network and Sharing Center" in the context menu of network connections
After that, you need to open the control menu for wireless networks. This is done using the corresponding button on the left side of the screen.
Go to the "Wireless Network Management" section
Call the context menu of the network that gives an error, and select the "Delete network" item.
Right click on the connection and click "Delete Network"
And then try to connect to the network again. Now that there is no saved data about this network, the connection should work fine if the network is not password protected.

In Windows 10, this problem is solved a little differently:

The problem may arise, for example, due to careless data changes in the connection settings.

Other Ways to Help Connect

And now let's look at a few common solutions that can help you with various connection problems. In our case, when Wi-Fi connection is not possible, these methods will also help.

Rebooting the router

The easiest way, which is advised by all providers in the first place. Of course, this will not help with serious problems, but it can fix one-time connection problems. The best way to reboot is as follows:

Checking and installing network drivers

Updating network drivers is no more difficult than updating drivers for any other hardware. You can do this using the automatic driver download system as follows:

Press the key combination Win + X to open the quick access menu and select the “Device Manager” section there. Another way to get to this menu is to right-click on the Start icon.
Select the "Device Manager" section in the quick access menu
In Device Manager, find the "Network adapters" section. Expand this tab and you will see your network devices. And then right click on the available hardware. After the context menu opens, select the action "Update drivers ...". To determine if a device needs a driver update, pay attention to its name and the presence or absence of an icon indicating that drivers need to be updated.
Open the "Network Adapters" section and click "Update Drivers" on the desired device
You will be asked how to upgrade. If there is an Internet connection (for example, using a cable, since a wi-fi connection is not available), then just click on the "Automatically search for updated drivers" button.
Select "Automatically search for updated drivers" if you have a network connection
Wait until the end of the search, download and installation of drivers.
Wait until the end of the search for drivers on the network and their installation
If there is no network access, you must download the driver for your network adapter from another device and select the "Search for drivers on this computer" option.
To search for drivers yourself, select "Search for drivers on this computer"
Specify the location of the folder with the drivers for their further installation.
Specify the location of the drivers on the computer and click on the "Next" button
After the installation is completed in one way or another, restart the computer.
Try connecting to the wi-fi network again to see if your problem is resolved.

If a simple update did not help, try completely uninstalling the driver and reinstalling it in the same way.

Reset router settings

If problems with the Internet do not disappear and there is still no connection to wi-fi, it is worth resorting to a more radical way to fix this problem. Namely, reset the router settings and configure it from scratch. You should not do this if you are unsure of your own knowledge and attentiveness - you risk being left without access to the Internet. You can reset your router in the following way:

Open any browser and enter the numbers of your local address in its address bar. Try numbers: 192.168.1.1; 192.168.0.1; 192.168.0.254. One of these addresses will be correct.
Enter the local address of your computer in the browser to open the router settings
To log into your account, enter the word admin as both password and login.
Use the word admin as your username and password
Go to the Factory Defaults section and click on the Restore button to completely reset your router.
Press the Restore button to perform a full reset of the router
Another way to reset the settings is to find the RESET button on the back of the device and hold it down for a few seconds.

On modern phones, the ability to make mobile calls is just one of the functions. And for many, this feature is not the most demanded. What do we mostly do on a smartphone? We watch videos, use social networks, chat in instant messengers, browse websites, play games, etc., and for this we need an Internet connection. And when the phone does not connect to Wi-Fi, and the mobile Internet is very slow, expensive, or not available at all, then this is a whole tragedy. A phone without the Internet, like a computer - it’s not clear why you need it 🙂

I may be exaggerating a little, but that's basically it. All phones that run Android (Samsung, Lenovo, Huawei, Xiaomi, Sony, Asus, Meizu and others) and iOS (Apple iPhone) require an internet connection. At least for setting up, updating programs and systems, synchronization, etc. Now there are no problems with this. Almost every home has a Wi-Fi router that distributes a wireless network. There are open Wi-Fi networks of neighbors, and a lot of open networks from shopping centers, cafes, shops and other establishments. Even subways, trains, buses and planes have Wi-Fi. You can always stay online even without mobile Internet.

But very often the phone just does not want to connect to Wi-Fi. Such problems are not only with open, public networks. (where, as a rule, the problem is on the side of the network itself) but also with home Wi-Fi. Usually I have problems connecting to one particular network. And sometimes the smartphone just works with the router, then disconnects from it and does not connect again. Or refuses to connect after replacing the router, some settings, installing programs, etc.

We will consider solutions for Android phones. If you have an iPhone, then see the article and.

Why is there no Wi-Fi connection on my phone and what should I do first?

First of all, it is very important to determine what exactly the problem is in your case:

The phone does not connect to the Wi-Fi network at all. Writes "Saved", constantly obtaining an IP address, authentication error, authentication error, incorrect password, error connecting to a Wi-Fi network, etc.
The phone is connected to the Wi-Fi router, but the Internet does not work. Near the network itself, there may be a message "The Internet may not be available", an exclamation mark, or simply there will be no access to the Internet through the smartphone's browser, or in programs. "No internet connection" or "Check your network connection" error. At the same time, the phone is connected to Wi-Fi.
There is another option when the phone does not see the desired Wi-Fi network. I talked about solving this problem in an article. We will not consider it today.

No matter what problem you have. Whether you are connecting to your home network, or to a public network, try these steps:

Disable and re-enable Wi-Fi on your smartphone. Better yet, reboot it.
Restart your router if you have access to it. Just turn off the power for a few minutes and turn it back on.
Check if other devices are connected and if the Internet works on them. This is especially true in the case when a problem arose with connecting to a home Wi-Fi router.
If you cannot connect your phone to a public Wi-Fi network in the subway, cafe, store, then most likely the reason is in the access point itself. Perhaps it just glitched, is temporarily out of service, or can't handle the sheer volume of customers. Just connect to another network, or try connecting later.
Remember, after which the connection problems began. Perhaps you changed some settings on your router or phone, connected new devices, installed some programs, or something like that. This will help you find the cause and fix it quickly.

To make it easier for you to find and apply the solution, I will further divide the article into two parts: in the first part I will tell you what to do if the smartphone does not connect to Wi-Fi (various errors appear, writes saved, etc.), and in the second part - how to solve the problem when the mobile device is connected to a wireless network, but the Internet does not work.

Smartphone not connecting to home/public Wi-Fi (error appears)

To clarify: in this section, we will consider cases when, when trying to connect to some kind of wireless network, our Android device does not connect at all (it happens that there is a connection but the Internet does not work, read about this in the second section of this article).

Main mistakes:

"Saved" error (WPA2 or WPA) .
Writes "Authentication error occurred", or "Authentication error".
It takes a long time to connect, or it constantly writes "obtaining an IP address".

Basic solutions on the phone

These solutions often help when a device has previously connected to this wireless network, but suddenly stops connecting.

Don't forget to reboot your mobile device and router first!

1 Delete the Wi-Fi network on your phone. Just go to the Wi-Fi settings, select the desired network, click on it and hold (or just click) and select "Delete network", or "Forget network".

Then again select the network from the list, enter the password and try to connect.

2 I recommend doing a full reset of the network settings. On Android, this can be done in the "Reset" section. Item "Reset network settings". Depending on the phone manufacturer and Android version, these settings may differ slightly.

Then you will need to reconnect to the wireless network. Perhaps everything will connect and start working.

Error "Saved", "Authentication", "Authentication Failed"

Such messages very often appear due to the fact that we Wrong Wi-Fi password.

Delete the network, or do a network reset (I wrote about it above).

According to my observations, when the phone is connected, it writes saved, or an authentication error due to the fact that the phone "does not like" some of the Wi-Fi network settings that are set on the router. I have to enter the network mode (b / g / n / ac), security type, channel and channel width, region, etc. There was even a case when the smartphone did not connect until the Wi-Fi network name (SSID) was changed .

In this case, you can try changing some settings on your router. Of course, only if there are problems with the home network. We cannot change the network settings in the same metro.

I also wrote about this problem in the article:.

I will write about solutions that can be applied on the router below in the article.

Obtaining an IP address... and the phone won't connect to Wi-Fi

We enter the password on the phone and the connection to Wi-Fi hangs with the status "Obtaining an IP address ...". Familiar situation? Most often this happens for three reasons:

Automatic IP settings are disabled on the phone (possibly static addresses are set).
The DHCP server is disabled or turned off on the router. But by default, the DHCP server is always enabled, and it is very rarely disabled.
Other access point restrictions. For example, your device is blocked in the router settings. Perhaps one of your relatives did it. Or the owner of the network to which you connected your phone.

Solutions:

On your smartphone, open the properties of the specific wireless network and make sure that "DHCP" is set in the "IP Settings" settings. If there is "Static", then change to "DHCP".

Check if the DHCP server is running on the router. But most likely it works, it is unlikely that this is the reason. Especially if other devices connect without entering static IP addresses.

Well, do not forget that you (your device) could simply disable (block) in the settings of the router, which broadcasts a wireless network to which you cannot connect your phone.

Setting up a router to solve an Android smartphone connection problem?

There, find the section with the Wi-Fi network settings (Wireless) and try changing the following parameters:

Don't forget to save your settings every time and reboot your router! Remember what parameters and where you change.

The phone is connected to Wi-Fi but the Internet does not work

It seems to me that the problem with the lack of an Internet connection with an active Wi-Fi connection is much more common than the connection errors that I wrote about above.

From my experience, I can say that this happens very often due to Android settings. (time and date, for example), problems with DNS addresses and due to some programs (for example, the Freedom app). Sometimes (app store). Writes that there is no Internet connection. But wifi is connected.

I don’t know how it is on other Android devices, but on Samsung phones.

What you need to find out:

Does the Internet work on other devices when connected to this "problem" network. If it works, then we are looking for the reason in the phone. If it does not work, then the problem is on the side of the router (or provider) and you need to solve it. This is where my article might come in handy.
You can also try to connect your phone that connects to Wi-Fi but on which the Internet does not work to other networks. So we can also understand on whose side the problem is.

It seems to have been found out. If the router is guilty, then we look for and solve the problem on its side. If this is not a Wi-Fi network in the subway, or in another transport / institution (to the settings of which we do not have access). If the reason is in our smartphone, then we look at the solutions and links to other articles that I will provide below.

Time and date

Who would have thought that the phone might not connect to Wi-Fi due to incorrect date and time settings. But it happens!

Go to Android settings and check if the time and date are set correctly.

You can try turning off automatic settings and setting everything manually.

Problem with DNS

I can’t say exactly why this happens, but sometimes the Internet on the phone starts working only after the Wi-Fi network properties are registered.

To do this, open the properties of the Wi-Fi network to which the smartphone is connected. (but no internet access) and set DNS in additional parameters:

This is what it looks like on a Samsung phone:

After that, the Internet should work. You can disable / enable Wi-Fi, or restart the phone.

Proxy Server on Android

There are proxy server settings in the wireless network settings on your phone. So, if the proxy server is enabled, then the Internet connection most likely will not work. You need to open the properties of a specific Wi-Fi network and check / disable the proxy server.

Check that the settings are set to "Proxy" - "No" (or disabled).

Wi-Fi not working due to programs

I have heard more than once about the Freedom program, which somehow disables access to the Internet via Wi-Fi networks. On purpose or by accident, I don't know. But in the toga, the phone is connected to the home Wi-Fi network, or somewhere in the subway, but it does not load anything. I am sure that there are many such programs.

If you encounter Freedom, then you need to go to the settings of this program, click on "Stop" there and only then delete the application. You can also install Dr.Web antivirus on your phone and run a system scan.

Or perhaps you have these problems with the Internet appeared immediately after installing some other application. Try to remember what you installed recently.

Reset network or hard reset your phone (Android)

If all else fails, then resetting the network settings should be done anyway. How to do it, I wrote above in this article. Clearing network settings will not affect your settings, programs, or personal data in any way. You just have to re-enter passwords from all wireless networks to which you have previously connected.

Well, if nothing helped at all, including resetting the network, then most likely you will have to do a complete reset of the phone settings.

Only if you have already made sure that the reason for the lack of Internet connection is in your smartphone and no solutions have brought positive results.

If anything, I'm in touch in the comments. You can ask a question there, tell about your problem, or supplement the article with useful information.

Description:
For those who are going to get connected to Wi-Fi for the first time, it will be useful to learn how to set up Wi-Fi on your phone at home.
Selecting and connecting a router
The first thing to do is to purchase a router or Wi-Fi router, after reading the instructions for the device you plan to connect. The most important parameter in this case is the type of radio signal. Based on this, you need to choose the appropriate option. It is possible that the device only receives a signal from a specific network with a certain type of WER security. Ideally, you need to choose a router that can create an access point with the necessary parameters. After you have purchased a router with the necessary characteristics, you can connect wifi to your phone by following a series of sequential steps.
1. Connect the router to the network.
2. We connect the Internet cable to the appropriate connector on the case.
3. Enter the IP address in the address bar of the browser and open the settings web interface.
4. Select the WAN menu and begin the process of setting up an Internet connection.
5. Go to the Wi-Fi settings menu, where we set the access point parameters for the connected device.
6. Save the settings and reboot the router.
7. Open the Wi-Fi settings on your phone, add a new network, enter a name, select an authentication protocol and enter a password.
This completes the connection process.
But even if you did everything right, the phone may not connect to Wi-Fi, notifying you of an error.
Connection errors
It happens that the mobile phone works fine with Wi-Fi in public places and flatly refuses to see the home network. The reason for this, strange at first glance, behavior is not at all in the phone, but in the router, more precisely in its settings. It is very simple to solve this problem and it does not matter if the phone does not connect to the zyxel, asus or any other Wi-Fi router. Go to the router settings using any Internet browser and type its IP address in the address bar. You can find out the IP of the router like this:
1. We go to the "start" and click "run" (Win + R).
2. In the command line, we type CMS.
3. Then in the "MS-DOS" window, type "Ipconfig / all" and press "enter".
4. In the window "Main gateway" we find the IP of the router, and we type it in the address bar of the browser.
5. Go to the DHCP section and check the box next to Enabled.
6. We register IP in the boxes Primary DNS and Default Gateway.
If everything is done correctly, your problem will be successfully solved.
Sometimes on the screen of the device appears the inscription "Authentication". It can occur in two cases: when an incorrect password is entered or security settings are incorrectly set. The first is to check the password. It must be eight characters long. If there are no problems with the password, you should check the security settings and set the type to WPA2.
Sometimes it happens that the settings have not changed, and the phone does not connect to the wifi router tp-link, d-link, asus, Rostelecom and others. The reason may be a change in the channel of the router you are using, or the appearance of another one that creates interference. In this case, you can solve the problem by changing the Wi-Fi channel.
There may be other reasons why a Samsung phone, or any other, does not connect to Wi-Fi, but before diving into their search, try simply rebooting the router. In most cases, this helps solve the problem.

Every smartphone user once faced such a problem as endlessly obtaining an IP address - phone won't connect to wifi and that's it! In this article I will tell you what to do if the phone does not see wifi, but instead constantly writes something like "authentication error", "obtaining IP" or "saved". But I’ll make a reservation right away that it is understood that, firstly, the smartphone itself is in good condition. And secondly, the WiFi network on the router is also configured correctly and everything works on other phones or computers.

Here is a list of the most common causes of error:

Invalid IP address
Radio channel Wireless
Encryption type
China motherfucking..

To immediately dismiss problems when the phone does not see wifi, which may be related to the router, try rebooting it and making sure that the DHCP server is enabled on it. That is, the router automatically distributes IP addresses to devices connecting to it.

In addition, you need to make sure that the SSID of the network is not hidden in the wireless settings on the router - often, to protect the connection from prying eyes, they activate this function, due to which the phone does not see the wifi network, although it actually works.

Reasons why the phone does not connect to WiFi

Now in detail about each item. The first thing I do immediately if the phone does not connect to WiFi is to set a static IP address on it.

For Android and iPhone, this is done almost the same way - go to "Settings> WiFi", see our active network connection and click on the arrow (on Android) or on the "i" icon on the iPhone / iPad.

IP for the phone from the range of addresses set in the router and available for use. If the router address is 192.168.1.1, then 192.168.1.45 can be assigned to the phone, for example.
Subnet mask - 255.255.255.0
The router is the IP of the router. In most models, by default, it has an address of either 192.168.1.1 or 192.168.0.1 - try them, if it doesn't work, then contact your network administrator.
DNS is also the IP of the router, or you can use one of Google's public addresses - 8.8.8.8 or 8.8.4.4.

On Android phones, you will need to scroll down the page to the drop-down menu "IP Settings" and change DHCP to "Custom". Additional forms will open for entering the same parameters.

What to do if the phone does not see WiFi?

And a few more ways to solve the problem when it comes to the fact that the phone does not connect to WiFi.

A possible reason for the authentication failure may be the choice of radio channel for your wireless signal. I talked about it in detail in an article about, so I won’t explain for a long time how to set it up. And here it is worth noting that modern routers support up to 16 channels, while the older standard that smartphones adhere to had only 11 channels. If your router is set to automatic channel selection mode, then it can easily switch to channels 12 or 13 (exactly 13 channels are allowed for use over WiFi in Europe), and accordingly, the phone simply will not see it. So if you want a constant and stable connection on all devices, set the channel on the router manually from 1 to 11.

If the phone is on Android, I want to upset you a little - the Android kernel does not always work correctly with the WPA2-TKIP encryption type, so if you have this type configured, then this may be the cause of problems with the Internet, and that the phone writes "connection saved" , "getting ip" and other nonsense. This is especially true for cheap Chinese products.

The topic of China cannot be bypassed with regard to the routers themselves - often their products have not quite standard modes of operation - both in terms of channels, and in terms of encryption and other indicators, so the modes of a Chinese router may not be fully understood by a "purebred" Android. The way out is to change the router to the production of a more famous brand and a model of a higher class.
