No internet connection. No internet connection

Many users sooner or later have problems with Wi-Fi connection. The cause of this problem can be either the Wi-Fi router or router itself, or its incorrect configuration (IP addresses are incorrectly configured, the settings for the address , 192.168.0.1, etc. are lost). As a result of this, the Internet seems to be available, for example, when connecting the cable directly to the computer, but Wi-Fi does not work and there is no connection.

It may also be that the Internet via Wi-Fi works on one device, such as a tablet, but not on another. How to solve this problem? (The solution is discussed using the example Wi-Fi router from TP-link, but can also be used on routers, routers and access points).

First of all, you need to correctly configure the router at http://192.168.1.1, the standard login and password for logging in is admin/admin.

Setting up a modem, router, router or Wi-Fi access point.

If you find out that the problem is in the network device distributing Wi-Fi, then you need to configure it correctly. See the video below for configuration examples:

Checking and setting up a Wi-Fi router, router or access point on a laptop/netbook or tablet.

If one of your devices (or none) won't connect, the first thing you need to do is figure out why. It can be in the laptop/tablet/computer, or in the router, or the provider may be to blame (for example, a line break).

You will also need to make sure that all network devices are working properly. And also, just in case, try to temporarily disable your antivirus or firewall, they can also block the connection. In any case, it is better to start over and act in order to find out where the root of evil is buried. So let's begin.

Make sure that the Internet works without a Wi-Fi network by directly connecting the network cable to the computer. If the Internet works properly on at least one of your devices, then the problem is not with the provider, move on, otherwise, contact your communication service provider.
Now you need to connect the cable to Wi-Fi and try to connect to the network on all devices. If none of them connect to Wi-Fi, or connect but there is no Internet access, then the problem is in your router, router, or access point. If some devices work (sites load, Internet pages open), while others do not have access to the Internet, then the problem is in the configuration of these devices, for example, a computer with a Wi-Fi adapter, laptop or tablet.

Wi-Fi does not work on a laptop or computer.

On laptop Wi-Fi may not work due to incorrect setting network, network connection or wireless network connection. Possibly in progress Wi-Fi settings or any other, for example local network You have lost the Internet, or rather your connection to the Internet.

This could happen, for example, if you unchecked the “Obtain an IP address automatically” checkbox or set a static IP address (manually). At correct setting wireless connection of a laptop or computer and a Wi-Fi distributing device, the IP address should be obtained automatically (for most cases).

To check the functionality of the wireless connection, connect to a Wi-Fi network (if you can’t connect, then you need to configure your router, router or access point). So you're connected, but you see an exclamation mark on the connection icon.
Left-click once on the icon and go to Network and Sharing Center shared access", on the left select "Change adapter settings".

Make sure that “Wireless Network Connection” is active and working (otherwise, select “Enable” by right-clicking on it).

Next, right-click on the “Wireless Network Connection” icon and go to “Properties”. Select “Internet Protocol Version 4 TCP/IP” and go to its properties.

Check the boxes so that IP and DNS are obtained automatically and save the settings (if automatic mode installed, just close the window).

After this, restart your laptop or computer, your Wi-Fi network must earn. If this does not help, check the settings of the device that distributes the Internet (router, access point, modem or router).

I will be happy to answer any questions you have in the comments to this article. Good luck with the setup!

Today we are all highly dependent on the Internet. And when it doesn’t work, panic immediately sets in, your heart sinks into your heels and life seems meaningless. It may be funny to you, but for some it really is.

The user is especially lost when the Internet is connected, but does not work. Today I will tell you why this happens and what to do if this happens to your network.

Why doesn't the Internet work?

If you are connected to the Internet, but it is not working, the first thing you need to do is find the cause of the problem. To do this, you need to restart all devices that are connected to the Internet. This means a router, a computer, etc. Most often, such a reboot completely solves all problems with the Internet, and it starts working properly. If, after rebooting the router and computer, you do not get the expected result, move on to the next “therapeutic” procedures.

Today, most people connect to the Internet using a Wi-Fi router. If you have the same, then you need to check whether the Internet access indicator on the router is on or not. For those users who use a TP-Link router, the Internet access signal is marked with a globe icon. On other routers, this signal is most often signed “Internet”.

If the indicator is off, you need to check your router settings. If everything is fine with them, then we call the technical support of our provider and ask why there is no Internet, perhaps just repairing the highway or network.

But, if the indicator is on, then there is a connection and the provider is not to blame. Check Internet access on other devices. It doesn’t matter what it will be - a phone, a tablet or another laptop. This way you can figure out which direction you should dig next to solve this problem. I’ll say right away that the case when a router is connected to the Internet, which is known to work well, but at the same time it does not distribute it to other devices, is considered a very rare case. The reason for this problem lies in the failure of the router. It's not difficult to fix this. You need to reset all settings to standard and reconfigure it again, remember that after the reset all settings will be lost and the Internet may not work until the router is configured correctly!

Cases often occur when only one device or computer cannot connect to the Internet using a router, but everyone else can easily access it. In this case, you need to look for the cause directly on this device.

If you are connected to mobile Internet via a USB modem or WiFi module connected to a USB port, then try disconnecting it and reconnecting it. If this doesn't help, try using a different port to connect. Perhaps reinstalling the driver will help you solve this problem.

Checking your Internet connection in Windows

If the Internet is connected to your PC or laptop, but does not work, and you are absolutely sure that the reason for this is incorrect settings, then you need to perform a series of procedures that will quickly solve your problem.

You need to start reconfiguring by pinging any popular site. To do this, press the combination “Win + R”. This will bring up the “Run” window.

In the text input field, you need to enter the following “cmd” and click on “OK”. If you are not a fan of my site, you can write Google. After that, press enter and wait for the result. If everything is fine, the server will send you something like this:

If the response from the server contains the line “The connection check failed to find the nodepec-komp.com. Check the host name and try again,” then you need to type another command, for example “ping .8.8.8.8”. This is the IP address of the public DNS server from Google, which will always be available. If the computer has access to an external network, then the answer will be the same as in the picture above, but with different numbers after “answer from...”.

If a ping passes through an IP address, but does not open in the browser, then most often this indicates that there is an Internet connection, but the network does not work due to incorrect configuration of the network card, namely, the address is not registered in them or the address is entered incorrectly DNS servers. I'll tell you how to fix this a little later.

If you observe a different response from the server, then you need to check access to the router. We will also check using ping. You can find out the router's IP address on a sticker that is glued to reverse side his body. Most often, the IP address of routers is “192.168.1.1” or “192.168.0.1”. The first address is registered on my router, so I received this answer:

If the router pings, but the Internet node does not, then most likely the reason lies again in the settings of the router or in the router itself.

But if the router is not available for server requests, then there is a reason to go into the settings of the network adapter on the computer. But, before doing this, disable your antivirus and firewall, if you have one. Sometimes it is these two “comrades” that cause problems with the Internet.

If after this the Internet does not work, although there is also a connection, press the key combination “Win + R” again, but now in the “open” field we write “ncpa.cpl.”.

If you have entered everything correctly, the Windows network connections window will open. In it you need to find your active connection and right-click on it, then select “properties”. In the window that opens, look for the line “IP version 4 (TCP/IPv4)” and double-click on it to open the protocol parameters .

Check “Obtain an IP address automatically” and “Obtain a DNS server address automatically”. Click OK and check the result in the browser.

If this does not help, then check the box “Use the following addresses.” You need to register the IP address from the subnet of your router. If it has IP 192.168.0.1, then set the computer to 192.168.0.2. If the router uses 192.168.1.1 , then on the PC it will be 192.168.1.2. Mask 255.255.255.0. You must specify the router address as the gateway. You can also specify the server from Google as the preferred DNS server.

In any case, watch my video on speeding up the Internet, if you apply all the settings, the Internet should work.

Increasing Internet speed to the maximum!

I hope that at least one of the methods will definitely help you regain access to the Internet. If none of the options for solving the problem helped you, then you will have to call a specialist who will determine the true cause and solve the problem. But I’m sure it won’t come to that and you’ll fix everything yourself.

Let's look at this situation: you connected to the router from your phone, the Android system shows that Wi-Fi is connected, but the Internet does not work. In addition, the network icon shows that the signal is excellent, but not a single online program is functioning. In our article we will look at options to solve this problem.

Troubleshooting

Unfortunately, there cannot be an unambiguous solution in this situation, and this is the whole difficulty. We will describe obvious solutions for the most common reasons why the Internet does not work on the phone.

Important nuances

Before you start looking for a problem in your phone, we strongly recommend that you follow some steps; in this case, it may turn out that the problem is not with your device, but with the router or even with the provider.

Make sure that your Internet access service is paid to the operator.
Check if the Internet works on your computer connected via cable.
Try connecting any other device to the router via Wi-Fi and access the Internet through it.

If you have difficulties at any stage, most likely the problem is not with your Android. If everything went well, then move on to setting up Android.

Rebooting the Router

If your router has not been turned off or rebooted for a long time, then during long-term continuous operation it may experience failures. They can manifest themselves in completely different ways, for example: two Android devices are connected to Wi-Fi, but the Internet is distributed to one of them, and does not work on the other.

Rebooting the mobile device

The situation described for the router also applies to your tablet or phone: problems may occur in software. To eliminate minor faults The easiest way is to reboot, after which they are eliminated by the system automatically.

Reconnecting to the network

This does not mean simply turning off the network module, and then turning it on again and waiting for reconnection, but to do this through the settings: “Forget network”, and then connect again by entering the password (if you have one).

On Android 6.0.1 this is done in the following way:

Go to settings.

Select the “Wi-Fi” item.

Find the name of your network and press it until a list of actions appears.

Select “Delete this network”

Next, tap on the same network and select “Connect”, having first entered the password (if one has been set).

Setting the correct date

A date in your smartphone that does not correspond to the real one may also be the cause of a situation where Wi-Fi on your phone does not work: Wi-Fi is connected, but there is no Internet on Android. Check - if the date is indeed incorrect, you can change it as follows:

In the settings, select “Date and time”.

Activate the checkboxes next to the items “Use network time” and “Use network time zone,” although the second item is not so necessary.

After that your real time will be requested from your operator's network and will correspond to reality.

If there are other wireless gadgets in the room, their signals can interfere with your smartphone or tablet. We recommend changing the channel in the router settings.

Due to the wide variety of router manufacturers, we cannot provide universal instructions for changing the channel: to do this, refer to the user manual of your model.

In our case, we used TP-Link: we had to go to the administrative menu in “Wireless”> “Wireless Settings” and change the channel to any other, then click on “Save”, as shown in the figure.

In the router settings, you need to select WPA2-PSK protection and AES encryption in the “Automatic” modes. This mode is guaranteed to ensure successful connection of most devices.

Checking signal strength

If you and your device are not close enough to the access point and the Wi-Fi icon shows that the signal is weak, in rare cases this may cause problems with the Internet. Try to get closer to the broadcast source and see if the situation changes for the better.

Checking web authorization

If you are not using your own home internet, but simply connected to an unpassword-protected point, then most likely this is the Internet of some company that uses protection not by setting a password for the connection, but through web authorization. That is, you can easily connect to an access point, but not a single program will show that you are online. To check this, just open your browser and go to some page. If you really have web authorization, you will be automatically redirected to the authorization window.

Changing your static IP address

And the last step in solving the problem is to try changing the address that the router gives to your version. This is done as follows:

In Wi-Fi settings, tap on the name of the desired network.

Tap on “Change network”.

Again I want to try to answer Daniel.

Daniel, I have installed the “N Series Multifunctional Wireless Router” TP-LINK TL-WR842N.
I purchased and installed it when I was tired of “fiddling” with wires that were constantly getting in the way under my feet and not only for that reason.
Long before buying a router, I bought three “Wireless USB Network Adapters” TL-WN823N for my three desktop computers
and distributed WI-FI internet from your “main” (most powerful) computer, to which a high-speed Internet cable was connected. All traffic went through my computer, which entailed inconvenience - when I turned off my computer, I cut off Internet access to other family members and the load on my processor was noticeable.
By purchasing a router, I received a device that provides all my devices (personal computers, laptop, tablet and two smartphones) with equal and balanced speed access to the Internet.
Following the router's Quick Setup Guide, I created my own wireless network, with your password (not to be confused with the password for accessing a high-speed wired connection).
It is important here that the router connects to the Internet automatically, which is indicated by green lights. If the large light bulb (LED) glows green, it means the router has connected to the Internet and is ready to distribute the Internet; if it lights up yellow, then something is wrong with the connection to Internet provider via cable (possibly not configured correctly).
Connecting to the Wi-Fi network we created is the same for both a laptop and a phone - look at the list of available wireless connections, select the network with the name that we entered when setting up the router, and click “connect.” When you connect for the first time, the system will require you to enter a password - enter the password, again, the password that we “hammered” into the router during setup (but this is not the password for the high-speed connection, you can forget that password, the router will always remember it).

Now about what all the fuss is about. As I understand, you decided to connect your computer to the router using a wire, and other devices using Wi-Fi. I didn’t try it, but immediately hung the router in the far corner and haven’t touched it since. I don’t remember why I didn’t try the way you are trying to connect, or maybe I even tried, but I can assume that it won’t work just like that, “from a running start.” I recently read articles on the internet, looking for an answer to the question of how to expand Wi-Fi coverage. So - it's not that simple. It is necessary to organize several networks and hierarchical dependence of devices (the required number of routers).
From the description of the TP-LINK router it does not at all follow that those four yellow connectors are an analogue of a HUB, designed to connect several computers to the Internet as if they were part of a Wi-Fi network, and they are not repeaters or branchers wired internet. It's still called a wireless router.....
I managed to find a description of the router on the Internet in Russian and with pictures:
img.mvideo.ru/ins/50041572.pdf
Perhaps you will be able to learn something and I would be grateful if you later share the solution you found (if you find it).
But I wouldn’t suffer for a long time and would buy a USB Wi-Fi adapter….

Android users sometimes experience that their connected Wi-Fi does not work. You can fix this problem yourself, in most cases it is solved very quickly.

Why is the connected network not working?

There are several options for why the connected Wi-Fi network does not work on your phone or tablet. But before you try to fix Android, you need to make sure that there are no problems with the Internet itself. Firstly, check if it is paid for, and secondly, try connecting to the same network using any other device. If the problem occurs there, then the problem is with the router or there are errors on the provider’s side.

If it does not work on only one device, then follow all the steps described below one by one. The reason may lie in incorrect settings, incorrect encryption type, incorrect date, or broken Wi-Fi module.

Troubleshooting

If it is unknown why exactly the network is not working, then use all the instructions in turn. They are arranged in ascending order of difficulty: from the easiest to quick method to complex options that are extremely rare.

Rebooting devices

First of all, reboot the router itself, check if the network on the device works after that. After this, restart the device itself and try connecting again. These actions will restart all processes, perhaps this will help them work correctly.

Turn off and turn on the router again

Reconnecting to the network

While in the settings of your phone or tablet, select the WLAN block.
Open the WLAN section
Find the network with which problems are occurring in the list, click on it.
Click on the desired network
Click on the “Forget” or “Delete” button. The device will forget that it had access to this network.
Click the “Delete” button
Click on network again, enter the password if you have one. Done, check if the error is gone.
Enter the password and connect to the network

Increasing signal level

The network will not work if the device is far from the router. Since the signal weakens with each meter, a situation may arise that the signal level at your location is enough to connect to the network, but the speed will be so terribly low that it is almost unnoticeable. Move the device closer to the router or, conversely, the router closer to the device.

Setting the correct date

Due to date inconsistencies, problems may occur on the device and the server processing Internet requests. Therefore it is necessary to set the correct date and time:

Replacing the broadcast channel

If there are many devices in a room, then each of them will emit some signal on a certain channel. Crossing channels will create interference, which will lead to problems with the Wi-Fi network.

For security reasons, the developers of your version of Android may have prohibited connecting to networks that use an outdated type of encryption. It is necessary to install the most modern look AES encryption. To do this, log into the router's management interface again and proceed to setting up the password and security. Select WPA2-PSK and Automatic encryption type. Reboot the router and try connecting to the network from the device.

Select the WPA2-PSK value

Is there web authorization?

If the problem only occurs with public networks(for example, at a train station or in a cafe), then it is worth checking whether web authorization is being used. In some cases, to deny access to the network, it is not a password that is used, but a method in which everyone can connect to the network, but only registered users can download anything through it. To check for web authorization, open any tab in any browser. If a page appears on the screen that requires you to enter a login, email or password, then you will have to log in to gain access to the Internet. Sometimes registration is paid or associated with some other conditions.

Deactivating automatic IP selection

By default, the IP address is selected automatically and changed statically. Maybe with your network it's better to be clearly defined. To set the IP, follow these steps:

While in the WLAN section (list of Wi-Fi networks), press the desired network for a couple of seconds and select the “Change network” function.
Click the “Change network” button
Go to advanced settings.
Expand the “Advanced settings” block
Set the IP Settings to Custom.
Set the value to “Custom”
Enter the value 192.168.1.y, where y is any number other than 1, since it is already occupied by the router. Save the changes and reconnect to the network.
Enter the address 192.168.1.y

Video: what to do if the connected Wi-Fi network does not work

Installing a different DNS server

The operation of the network depends on the DNS server. Your device may not be able to work with certain servers, so we will replace the default server with Google's public servers, they are free. While in additional settings networks (how to get into them is described in the previous paragraph), set static IP address selection, and set the values 8.8.4.4 and 8.8.8.8 for the main and backup DNS servers, respectively. Save your changes and try connecting to the network again.

Enter the value 8.8.4.4 and 8.8.8.8

What to do if nothing helps

If none of the above methods helped you fix the problem, then try to look for the reason in the router itself or contact technical support operator, there is a possibility that the error occurs on their side. If you are sure that the reason is in the device itself, there is only one thing left to do - reset the settings to factory settings. Please note that resetting will lead to the loss of all data stored in the device’s memory, so save it on another medium in advance. To perform a reset, go to the “Recovery and reset” block in the device settings, and then click on the “Reset” button and go through the procedure.

Click on the “Reset” button and complete the process

If Android connects to Wi-Fi, but does not download anything through this network, you need to restart the router, device, reconnect, change IP and DNS settings. The surest, but at the same time radical, method is to reset the settings. If this does not help, the Wi-Fi module is broken.
