The computer is connected to the network but does not access the Internet. Wireless network connection: no connection, connection error and other problems. Setting up a wireless Wi-Fi network. Checking your Internet connection

Before you begin to find out why Wi-Fi or the Internet does not work, you should know (especially for those who have just purchased a Wi-Fi router) that it is not enough to just connect the provider’s cable to the router, you also need to configure it (set up the Internet and Wi-Fi network ). All of the methods described below are valid if Wi-Fi and the Internet were working for you before, and then suddenly stopped or you cannot connect a new device to Wi-Fi. For convenience, I divided the article into two parts, the first is devoted to the inability to connect to a wireless network, the second part will answer your questions if you are connected to a Wi-Fi network, but there is no Internet.

Cannot connect to Wi-Fi network.

Reboot the router.

The first thing you need to do if you have problems connecting to a Wi-Fi network is to restart the router. To do this, simply disconnect the power supply from the router and connect it again after a few seconds. After 1-2 minutes. The device will boot, then try connecting to the wireless network again. To avoid such situations in the future, I recommend updating the router firmware (perhaps the manufacturer knows about the problem and fixed it in the new firmware).

Enabling the Wi-Fi module on the laptop.

Check if Wi-Fi is turned on on your laptop, I won’t bother, I described all the ways to turn on Wi-Fi in the article How to turn on Wi-Fi on a laptop .

Change the wireless network mode.

If you are trying to connect a device (laptop, smartphone) that is more than 5-7 years old, you must take into account that it may not support the modern Wi-Fi mode - n. Therefore, you need to switch the router to an operating mode that is supported by the device or enable mixed mode b/g/n. More details about Wi-Fi operating modes are described. In order to switch the wireless network mode, you need to go to the router’s web interface, go to the Wi-Fi settings and select the appropriate mode.

Removing a duplicate network SSID.

One of the possible problems of not being able to connect to Wi-Fi is a duplicate Wi-Fi network name (SSID). Suppose you come to your friends, their Wi-Fi network is called “Home”, you successfully connected to it. Time passed and you came across the same network name with other friends or at home. The laptop (this also applies to tablets and smartphones) tries to connect to the network using the previously saved password, but it fails because a new password is used for this name. To solve this problem, you need to remove the matching network from the list of saved Wi-Fi networks.

To do this, right-click on network icon in the lower right corner of the screen and select "Network and Sharing Center."

After this, you will see a list of saved wireless networks. If you see that the network you are trying to connect to is in this list, you need to remove it from this list. Select the network and click the "Delete" button. After this, you will need to enter a password to connect to the wireless network.

No Internet via Wi-Fi.

Internet payment check.

The simplest thing that can happen when the Internet is not working is that it’s time to pay for it or the provider is working on it. To clarify the situation, call your provider and find out whether you have a debt for the Internet and whether work is being done on the line.

Static IP address.

One of the problems with the Internet not working may be that the registered static address does not have the network settings that are necessary. In this case, I recommend using automatic network settings retrieval. To do this, you need to go to the Network and Sharing Center. One way to do this is to right-click on network icon in the lower right corner of the screen and select "Network and Sharing Center".

Another way is to use hotkeys + , enter the command ncpa.cpl and press Enter.

It doesn’t matter which method you used, the result will be the same - the Network Connections window will appear on the monitor. Next, you need to double-click on the wireless connection. In the status window that opens, select “Properties” in the properties window “Internet Protocol Version 4 (TCP/IPv4)”

Problem with the router.

The Internet may not work due to a router failure; the simplest thing you can do is reboot it. There are situations when the router resets the Internet settings, in this case you need to connect to it via the web interface and re-enter the Internet settings, in order to experience fewer problems with the router in the future, I recommend updating its firmware.

Conclusion

In this article, I described all the ways I know to solve problems with Wi-Fi and the Internet. If these methods do not help you, you can describe the problem in detail in the comments and I, together with the readers of this site, will try to help you.

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 a repair of 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 the mobile Internet via a USB modem or WiFi module plugged into a USB port, 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 the 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 “During the connection check, the node could not be foundpec-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 the back of its case. 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.

The laptop is convenient because it has a built-in wifi module and you can do without pulling cables. But sometimes something unpleasant happens - the Internet on the laptop does not work. Let's figure out why and what to do in this situation.

Why does the Internet not work on a laptop?

There may be several reasons:

The first is that you forgot to pay for the Internet, and the provider has limited access. You need to go to your personal account (data from it must be specified in your agreement with the provider) and check the status of your account. There is a connection, but the data is transferred very slowly? Maybe your Internet speed was cut off for non-payment. Some companies do this. For example, Beeline or Rostelecom.

The second is interruptions on the part of the provider. If the account is in order and there is money, try to find out if there is a connection in principle. To do this, connect the network cable directly to the laptop and check if the Internet connection works. No? Check settings:

In the case when you do not have a cable connection at all (you recently changed the OS), then you need to create one. To do this you need:

Did not help? Connect the cable to another laptop or PC. If the network appears, your network card may have burned out.
If the Internet does not work on another laptop via cable, call the technical support of your provider and find out the reason.

The third is poor coverage. When using Internet wifi with a 3G or 4G modem, or distributing it from a phone, there may be no network coverage at the point where you are and wifi does not work. For example, on the highway or outside the city. Check your mobile phone to see if there is a connection. Wireless Internet on a laptop will not work if the tower is located far away.

Fourth, you and your laptop have gone beyond the coverage of your wifi router. For example, you are outside the city in the country. The router is installed in the house, and you are trying to get wifi in the attic, under the roof. Be prepared that the roof will screen the connection or the distance is simply too long (in the case of a weak wifi router). Try moving closer to the router. The connection may begin to work.

Fifth, there are problems with the wifi router and for this reason the Internet on the laptop does not work via wifi. Try rebooting it. To do this, simply unplug its power supply, wait 30 seconds and plug it in again.

Sixth - the drivers have fallen off. Check if everything is ok with the software. To do this, go to Device Manager and check if there is a yellow exclamation mark on any network adapter. In the screenshot there is a red circle around where the yellow icon may appear.

If there is one, right-click and select the desired command.


Update your drivers.

Seventh – the network adapter is disabled. Hover your mouse pointer over it, right-click. If you see the “Enable” command, it means it was disabled for some reason.


Check all adapters.

Eighth – the wifi router settings have been lost. Enter the address http://192.168.1.1 in your browser (it may be different - look on the router itself) and enter your login and password (most often admin/admin). In the window, check all connection settings:

1. Connection type (taken from the contract or from technical support)
2. Network name
3. Encryption type (WPA2/PSK)
4. Virtual server mode activity virtual server mode - DCHP
   Basically, one of these steps should help you gain access to the network or diagnose the problem.

Once again, we list the main steps if the Internet on a laptop does not work well via a wifi router or it has stopped working altogether:

1. Check your account - this is often the reason why the Internet on a laptop works slowly via wifi.
2. Reboot your wifi router - it might freeze.
3. Check your wifi router settings.
4. Check the integrity of the cable and plug it into the laptop and check the connection. If it has not been created before, create it. If a connection appears, the problem is in the router or wifi drivers on the laptop. Update them.
5. Try connecting the cable to another laptop or PC. If the connection works, your network card is disabled or burned out. If not, there is a problem on the provider’s side.

Have a great day!

The article is more about wired Internet or Wi-Fi, not mobile, but it will be instructive for everyone. Let's divide connection problems into two types: physical and software. Physical – this is everything related to equipment, wires and problems with the provider itself. Software ones are something that depends on the settings of Windows and/or the router.

How to check if the Internet is working or the problem is elsewhere

Sometimes updating the device firmware helps. This is especially useful if your router has been infected with a virus. Yes, yes, and this is no longer uncommon! How to do this, read on the website of your router, everything is very individual. I won’t give step-by-step instructions, even in general terms, because... I think this should be done by a specialist.

If you know how to reconfigure the Internet on a router, then I recommend setting it to default first. Another sure sign to exclude a router is to connect the cable to the computer directly, bypassing the router.

Software problems and their solutions

For a number of obvious reasons, within the framework of the article, I can only help with specific recommendations on this point.

Incorrect connection settings

You are connected directly, without a router

It happens that network connection settings are lost in Windows 7/8/10. When you hover your mouse over the network icon, you can see the constant status of the network “Identification...”. There may not be obvious errors. To fix this, right-click on the connection icon and select “Network and Sharing Center”

In the screenshot there is a Wi-Fi connection icon, but if you are connected by wire, it will be in the form of a computer. Click on the connection, in my case it is “Wireless network connection”

A window should open in which you need to click the “Properties” button

Next, you need to enter the IP and DNS addresses provided by your Internet provider. Usually, they are specified in the contract, but you can call and ask. But, as usual, there is no need for this and it is enough to put the switches as in the screenshot, i.e. to automatically receive settings:

As one of the common solutions to the problem, I advise you to uncheck the TCP/IP protocol version 6. Let's reboot. It's all on the video too.

WiFi without internet access

When using a router, in 99% of cases, automatic acquisition of addresses should also be indicated (see above). To make sure that the network settings on your computer are correct, just try logging into . Everyone has different devices, but I showed how to do this in the general case at the end. Check if you log into the admin panel, but the Internet does not work, then there are problems with the WAN network settings on the router.

Also, a sure sign that the router itself does not have access to the Internet will have the following icon in the system tray:

When you hover over it, the message “Without Internet access” will appear. This means that the connection with the Wi-Fi router is established, but the Internet is not connected to it.

This can only be corrected by knowing the correct settings, which should be specified in the contract with the provider. You can also use automatic parameter detection. The general principles and example of setting up a router are described in the article “”; it is also suitable for a wired connection. All are described in another article.

Damaged TCP/IP and Winsock protocol parameters

Without going into technical details, I’ll just write what needs to be done, and you can repeat it yourself. Do this if none of the above helped you. And it is advisable to restore the system before executing commands. Then, if something goes wrong, you can roll back.

And the last piece of advice, but no less effective. In Windows there is such a thing as a firewall, it is also called a firewall. This software protects your computer from external threats, such as hacker attacks. But, if the settings are incorrect or damaged, it can block access to the network. So try Windows.

If the Internet works after this, you need to reset the firewall settings and then turn it back on. If you have an antivirus with a firewall function, then you need to disable it in its settings. This is usually done by right-clicking on the antivirus icon near the clock. Using ESET NOD32 as an example:

You need to reset your antivirus settings through its interface.

And here is the promised video with examples from the article:

Every user of the global network sooner or later faces the problem of accessing the network. There are many reasons, both software and hardware, why network access suddenly stops. In this article we will look at such a common error typical for Windows as “Unidentified network without Internet access.”

Any difficulty regarding the Internet and any network in general can arise for one of two main reasons - the fault of network equipment or the fault of software. An error like “Unidentified network without Internet access” usually results from malfunctions in the computer software or communication devices. This may include the actions of malware blocking the network, incorrect settings of network services of the operating system, PC network equipment or external communication devices (wired or Wi-Fi router, modem or even provider equipment).
A message like this means that the computer is currently connected to some network, but does not have access to the World Wide Web. An existing network is a connection, for example, through a wired router or another computer, to a WiFi network, as well as to the provider’s equipment (if a computer or laptop is connected to the Internet via a cable coming into the room).
We will try to figure out why this happens, and also give solutions on what to do in such a situation.

ISP related problems

If the PC is connected via a network cable coming into the room from outside, then access to the global network is most likely blocked due to the fault of the provider. The reason may be a situation with equipment malfunctions on the provider's side - a short-term malfunction, incorrect settings of the hub, lack of communication between the equipment and the provider's server (possibly due to a broken cable connection). But in such cases, there is nothing left to do except wait for the problem to be resolved by the provider.

A similar problem can occur due to the provider blocking access to the Internet due to the expiration of the subscription fee or a deliberate termination of the provision of services (this happens, for example, in the case of DDoS attacks on the server from the client’s computer). The last case of shutdown is, of course, very rare, but still possible.

In the last two cases, the laptop will also be connected to the network (provider equipment), but also without access to the World Wide Web. This is why Windows writes to the user “Unidentified network without Internet access.”

Network settings

If there is accurate information about the performance of the provider’s equipment and the absence of blocking on its part, then the problem most likely lies in communication devices (for example, a Wi-Fi router), local network settings, or in the settings of the OS itself. All this can be checked directly from your computer.

If in your case a wired or WiFi router is used as a communication device, the problem may be hidden in incorrect IPv4 protocol settings. You can fix them as follows (it is recommended to do further actions in any case, especially if you access the Internet via a local network via a router):

Now your laptop or computer should display information about a successful connection to the network. If there is Internet, Windows will write in the “Network Center...” section in the “Access Type” item – “Internet”.

But what should you do if Windows continues to report that there is no connection? Open the IPv4 protocol properties window again, and change the value “0” in all fields to “1”, like here:

The last step must be done in cases where the standard factory address of a wired or Wi-Fi router is different from “192.168.0.1”. If this address was changed by you or other users yourself, we recommend that you find it and enter the necessary data in the IPv4 properties.

For example, if your Wi-Fi router, which connects to a PC via a local network, has an IP address of “192.168.1.55”, then in the IPv4 settings in the “IP address” section you need to specify, for example, 192.168.1.10, and in “Default Gateway” and “Preferred DNS Server” change the last two digits to 1 and 55, respectively.

Does your laptop still say “No network access”? Then the Internet disappeared, most likely due to the settings of the wired or Wi-Fi router. But there is also a possibility that your laptop is experiencing connection difficulties due to a failure in the system’s network parameters. It can be fixed.

Resetting network settings

If the PC writes a message about the absence of the Internet due to a failure of the network parameters, then they can be returned to their original state by performing a few simple steps:

Windows also writes a message about the lack of access to the World Wide Web if the wired or Wi-Fi router has incorrect settings. There is a similar problem when the laptop connects to the Internet directly via a cable. If you have suspicions about this, then there is nothing left to do except call a specialist to set up your computer (but, most likely, you will have to set up a Wi-Fi router).

The difficulty of describing this problem in one article is that the provider may provide network access using one of several communication technologies - for example, ADSL or VPN. To connect a laptop or computer to the Internet, you need to obtain settings data from your provider, which, in most cases, is individual for each user and case. But describing them all is labor-intensive, so in such situations it is better to turn to specialists.
