No internet connection. Internet connection setup. Wi-Fi network without internet access. We solve the problem using the example of a TP-Link router

We have become practically dependent on the Internet. Without it, we can't spend peacefully free time, chat with your friends, look for information. Often the Internet becomes simply an integral part of our lives.

And of course, in situations where for some reason the Internet connection is interrupted, we are overwhelmed negative emotions. There is a desire to find and fix the problem that could lead to such a shutdown as soon as possible.

In this article, we will try to make life easier for those who may suffer a similar sad fate. Let's just look at a few situations in which the Internet connection may fail, as well as give advice on how to restore it. And, of course, here are some common reasons why there may be problems with the Network.

No internet connection. First steps

Imagine a situation in which you do not have the Internet. Do you understand that you would like to go to your favorite social network, watch a movie or perform any other action, but instead sit "waiting for a miracle." The first step is to establish at what stage the error occurred. Here you should answer a number of questions and conduct several tests.

Have you had Internet before, or is this its first launch after some updates? If the answer to the first part of the question is yes, then your task is to find the very changes, after which access to the Web was lost. Otherwise, if you have changed something (for example, changed the router), you need to look for the cause of the problem, which is quite obvious, in it. In this article, in order to learn how to establish the cause of the loss of Internet connection, we will analyze all the nodes in stages and characterize what questions may arise at each stage.

Provider

First of all, of course, the cause of the loss of the Network can be an error on the provider's side. This is the initial link of our "network chain". The reason for the loss of Internet access, in this case, may be, for example, non-payment for next period use. However, we will not talk about this in this article, since such problems are too commonplace to focus on them.

Diagnosing an error with a provider is not difficult - just remember if this has happened before; ask your neighbors who have the same internet if they have access; consider if you changed anything in the system that could lead to a situation where there is no Internet connection.

Of course, if the whole thing is really a mistake on the provider's side, you can't do anything - you just need to wait or use the services of another company if such a disconnect occurs too often or lasts a long time.

Modem

Often situations arise when access to the Network is lost along with the fact that the modem signals some kind of error. Then you need to turn to it - find out what exactly these or other signals on the device mean; try to understand why the connection has disappeared. The most common problems in such cases are problems with connecting elements (wires, adapters, weak contact somewhere at the input). Check them, disconnect and reconnect, and if possible, rearrange, replace with new analogues. After that, it will be clear what the cause of the problem is - in the modem itself or in the wires that directly serve to transmit the signal.

If the matter is in the wires, then replacing them with new ones will not be difficult; if it turned out that the problem lies in the modem, we recommend that you contact it in service center. However, as a rule, the modem itself should not fail without visible reasons. Perhaps a part of the board burned out in it, or the device was damaged, but then this should have been preceded by the modem getting wet or its failure. Thus, by remembering such events, you can unravel why there is still no active connection to the Network.

There may also be a situation when an Intertelecom (Sprint) wireless modem is used to connect to the Network. “No Internet connection” - Windows XP may display this message in this case, for the reason that the system simply does not have the appropriate drivers to “see” this device and recognize its signal. The problem is solved by a simple installation software appropriate for this modem. Finally, if this does not help, check the technical serviceability of the device; try to remember, after which an error could occur, whether there was any damage, and so on.

receiving device

If everything is fine with the provider, and your modem is functioning perfectly, you need to pay attention to the device itself, which is used to receive the signal. Everything is simple here: if you reinstalled the operating system, then, obviously, the message: “No Internet connection” Windows 7, delivered instead of Windows XP, displays precisely because of the lack of proper settings. There is no need to panic. The only thing that is required of you is a little time and, preferably, access to the Web on another device to search for tips and answers to your questions on sites and forums. And the solution to the problem will be easy setup Internet connection, which is carried out as required by the type of connection used. Dial-up access, for example, often doesn't need to be configured at all; on the other hand, establishing a connection through a VPN service can seem like a rather daunting process.

If we are talking about access to the web mobile device, for example, and the phone or tablet says: “No Internet connection”, you just need to know the Wi-Fi network key and its name. You can see them in the router settings. If you are concerned about the mobile Internet, then you need to configure it by entering the data of the access point. You can learn them, again, from the operator or communications consultant. Also, service providers often offer an automatic package of settings to simplify the user's task.

router

If you understand that the device works flawlessly, there are no problems on the side of the provider and the modem, and the router does not want to connect to the Network in any way, it is obviously the case. Firstly, in this case, you need to install, after which WiFi disappeared. The Internet connection could also be lost if the device was somehow damaged, its settings changed. If the matter is in the settings, carry out the procedure for entering the necessary parameters in the software part of the router again. In case of mechanical damage, the device must be taken in for repair.

Again, if the inscription "No Internet connection" (via WiFi) Windows 7 displays after the reinstallation has occurred operating system, maintaining the new parameters is mandatory. To understand if this is the only reason, you can also find out by using another computer if the problem also applies to it.

If there is no Internet connection through a router, but at the same time, no one touched the operating system, go to the device settings (using the address 192.168.0.1 or 192.168.1.1). For authorization, use the admin login and password and see if the router connects to the Network, if you entered the Internet login data correctly, and so on.

Examination

If you see the message: "No internet connection" (via WiFi), Windows 7 with its diagnostic tools won't help much. As practice shows, she gives the most vague advice in order to cover the most wide range possible problems. And you need to find and eliminate a specific cause, so we recommend checking each link as described earlier. In a practical way, even without special knowledge, you can set up your Internet, or at least find what the problem is and determine how to solve it.

Nothing helps

Of course, there may be situations when none of the above tips helped, you know what the reason is, and Windows 7 continues to display the “No Internet connection” message. What to do in this situation? Contact your ISP support! There you will be consulted and will be given an answer to the question of what is the cause of the problem.

Master's call

A way out of the situation can also be a call to the house of a master (specialist from the provider). However, you must admit that sometimes solving a problem on your own can bring more pleasure than the error “No Internet connection” eliminated with the help of a competent employee through a router.

There is always a reason

And finally, we present main advice, which you need to remember in any situation when you yourself are trying to find the reason for the lack of an Internet connection. There is always a reason! Remember this phrase when you think that the connection to the Network has disappeared "by itself", and you still do not understand what happened and what you should do now.

When you first find out where the failure occurred, what prevents you from connecting to your provider's service, at what stage the error was made, and only after that look for an answer to the question of how to fix the problem. In this case, of course, it is desirable to have Internet access from another device (for example, from mobile Internet on the device, unless the same tablet says: "No Internet connection", or a neighbor's computer), in order to look for explanations for your situation on various forums and sites. After all, no matter what mistake you have, there are at least a few hundred more people in the world (if not more) who have already encountered it and managed to discuss it to the smallest detail.

If devices connect to a Wi-Fi network, but the Internet does not work, you need to determine the cause. The problem may be in the Internet connection itself, in the router or laptop (or other connected gadget).

First, you should check if the Internet is working at all. To do this, the network cable is connected directly to the computer. If the Internet connection does not appear, you should contact the provider. Otherwise, check the settings of the router and devices connected to the wireless network.

To understand that the problem is not in a specific laptop or other connected user gadget, you need to connect other devices to the router, such as a phone, tablet, etc. If other devices also find Wi-Fi, but after connecting the network without access to the Internet (this is indicated on a laptop), sites do not load, then the problem lies in the incorrect settings of the router. If the connection is successful on other gadgets, the sites are loading, then the problem is in connecting a particular device.

How to solve a problem with a laptop, smartphone, tablet.

If only one device says " Unidentified network, no access to the Internet", You need to double-check the settings for the wireless connection to the network. When setting up the router, the user could accidentally change the connection data. You can check the correct settings on a laptop or computer as follows:

1. You need to connect to a Wi-Fi network.

2. Go to the Network and Sharing Center.

3. In the open window on the panel on the right, click "Change adapter settings".

4. In the open window, right-click on "Wireless network connection” and select “Properties”.

5. In the new window, select "Internet Protocol Version 4 (TCP/IPv4)" from the list and click "Properties".

6. In a new window, check if the items “Obtain an IP address automatically” and “Obtain DNS servers automatically” are selected. Check them if necessary and click OK.

7. Reboot OS. After the reboot, the Internet connection should appear. If the network, as before, without access to the Internet, it is possible that anti-virus programs or Firewalls are blocking the connection. Then you should turn them off.

How to solve the problem with the router.

Before setting up the router, you must first return to the factory settings. To do this, press the button on the back of the router and hold it for 10 seconds. After that, you need to go to the admin panel. To do this, enter the following address in the line of any Internet browser: http:// or http:// (TP-link, Dlink). In the window that appears, enter your login and password to enter, usually admin and admin. To fix the router, you need the WAN tab. Here you configure the Internet connection that connects to the router. SND providers use Dynamic IP, Static IP, L2TP, PPPoE, PPTP connections.

For example, Kyivstar uses Dynamic IP, the appropriate settings are set in the WAN section of this provider. If the provider uses another connection, for example, Static IP, then the setting with Dynamic IP will not work; the router will not connect to the Internet in this case. To set the correct settings, you need to find out which connection technology the provider uses. This information can be clarified with the provider itself or viewed on the Internet.

Sometimes providers create a binding to the MAC address, which can also affect the operation of the router. In this case, you need to connect the router via cable to a computer whose MAC address is registered with the provider, find the MAC Clone tab, click Clone MAC Address, and then Save. Update.

There are also situations of the following nature. The user decided to change Windows 8 to Windows 7. Before reinstalling, everything worked fine, but then problems began with connecting to the wireless network, the message “Unidentified network” appeared, that is, the Internet stopped working. To solve this problem, you need to go to the Network and Sharing Center, select Manage wireless networks.

Right-click on the network that you cannot connect to and select Properties. On the Security tab, click on the Advanced Settings section. Select the Enable Federal Information Processing Standard (FIPS) Compliant Mode for this network check box in the menu. This update should help resolve the connectivity issue.

Today I will consider a situation that users of operating systems very often face. Windows 7 And Windows 8. The essence of the problem is as follows, there is a network connection, but Network and Sharing Center writes that the Network without access to the Internet, the network icon in the tray has about a clock Exclamation point. In this case, in fact, the Internet may even be available. There may be several reasons for different options development of events. Let's take a closer look at each of them.

But first of all, if you are connected via modem, router or ONT optical terminal- I would advise reload it. If, after rebooting the device, Internet access resumed, the problem is definitely in the router itself, its settings, or the provider's network (it happens sometimes). In this case, we reset the router with the reset button, configure it again and check. If anyway after a while a message appears that Network without Internet access- try another router to check.

1. WiFi network without Internet access

This is the most common situation. The reason for this problem is most often the following. The vast majority of users are not aware at all what is an IP address and believes that for WiFi connection just enter the network security key. In most cases, this may indeed be enough, but not always. If on WiFi router disabled protocol DHCP, then you can easily connect to the network, but here IP address your wireless adapter on your laptop, tablet, or smartphone will not receive. Accordingly, you will not have access to the Internet, although the network is actually connected, but only partially.
By the way, this is also possible with a wired connection - the cable was plugged in, but the address was not received.
What to do? Enter the IP address manually. To register ip in windows 7 or Windows 8 you need to do the following:
Let's go to Control Panel and click on the icon Network and Sharing Center:

In the window that opens, click on the link Change adapter settings. You will see a list of network adapters. Right-click on the network adapter through which we connect to the router and select the menu item Properties:

You will see the network card properties window. Choose an item Internet Protocol Version 4 (TCP/IPv4) and double-click on it with the left mouse button. Here it is necessary write IP address, netmask, gateway and DNS address:

For most routers (except D-Link) should fit the following:
IP address — 192.168.1.2
mask — 255.255.255.0
Gateway — 192.168.1.1
primary DNS — 192.168.1.1
secondary DNS — 8.8.8.8
For D-Link routers:
IP address — 192.168.0.2
mask — 255.255.255.0
Gateway — 192.168.0.1
primary DNS — 192.168.0.1
secondary DNS — 8.8.8.8

2. There is Internet access, but still writes Network without Internet access

This problem is most often occurs when a computer is connected to the Internet through a proxy server . That is, there is Internet access, but it is, as it were, not direct, but through a server.
In this case, you can do the following:
We press the button Start select item Run(or press the key combination Win+R ) and in the window that opens, write:
gpedit.msc
You will open Local Group Policy Editor.
Local Computer Policy → Computer configuration → Administrative Templates → System → Internet Communication Management → Internet communication settings and turn on the parameter:
« Disable active probing for network connection status indicator «

By this you disable active probing . After that, the system will not check the Windows network connection states for whether the computer is connected to the Internet or to a restricted network.

In this article, we will try to figure out why and why the browser stops loading pages and visiting different sites. Despite the fact that the Internet continues to work normally, judging by the connection status on the notification panel. In this case, it does not matter at all whether you have a PC or a laptop. Windows 10, Windows 8, or Windows 7 is installed on it. And it doesn’t even matter how you connect to the Internet: via cable directly, or via a Wi-Fi router.

If there is some kind of red cross next to the icon, or a yellow exclamation mark, then the browser does not load the pages due to the lack of an Internet connection. And we need to solve this problem. First of all, we restart the computer and the router (if you have a connection through it). You may also find these articles helpful:

When the internet connected and working, then the icon should look like this:

Usually, when the Internet is available but the sites do not load, then programs such as Skype do not lose their connection to the Internet. Pay attention to this. And if your internet is working (connection status as in the screenshot above), but does not access sites through different browsers, then try to apply the recommendations that I will write about later in this article. And further:

• If you have a connection through a router, then check if the sites are loaded on other devices. If not, then reboot your router. You can also connect the Internet directly to your computer and try to go to some site. Perhaps this problem appeared due to the fault of the provider.
• In the event that the problem is only on one computer, then it is important to remember when and after what it appeared. For example, after installing some program.
• Restart your computer and run Windows Network Diagnostics. You need to right-click on the connection icon and select "Diagnose problems." You can write about the results in the comments.
• Try visiting different pages. Perhaps the problem is in one particular site. Also try different browsers.

The problem is clear, let's move on to solutions.

If the browser does not load pages, first of all we change the DNS

This is the most popular and most working solution to this problem. Almost always, it is because of problems with DNS that sites do not load when the Internet is running. And in such cases, I recommend registering DNS from Google. This is not at all difficult to do.

You need to go to network connections. Do it in a way that is convenient for you. You can press a keyboard shortcut Win+R, enter the command ncpa.cpl and click Ok.

Right-click on the connection through which you are connected to the Internet and select "Properties".

In the new window, select "IP version 4 (TCP/IPv4)" and click on the "Properties" button.

Like in the screenshot below.

Everything should work right away. If not, then try restarting your computer.

More information on this topic in the article:.

ipconfig/flushdns - flush DNS cache

Start a command prompt as an administrator and run the ipconfig /flushdns command. The DNS cache will be flushed and the issue may be resolved.

It should turn out something like this:

After that, it is advisable to reboot.

How proxy server settings can affect page loading in the browser

If some program, perhaps even malware, or we ourselves change the proxy server settings, then this can cause this problem. You need to check that there are no unnecessary settings in the proxy server settings.

In the control panel, find and open "Educator Properties". If you have Windows 10 installed, then this item will be called "Internet Options". You can type this phrase in the search, it will be faster.

On the "Connections" tab, click on the "Network settings" button. Check that the settings are like mine in the screenshot below.

If everything is fine with you, then move on to the next solution.

Reset network settings

In Windows 7, Windows 8 (and even in the top ten), you can reset the network settings with separate commands that you need to execute in turn on the command line running as administrator.

ipconfig /flushdns

ipconfig /registerdns

ipconfig /release

We execute the commands in turn.

Don't forget to restart your computer.

Avast installed?

If Avast antivirus is installed on your computer, then there is a high probability that the browser cannot load sites precisely because of it. There are reviews in the comments that reinstalling the antivirus solves this problem.

Try uninstalling Avast first. If the Internet works, you can install it back.

Nothing worked, any other options?

Check your computer for viruses. There are many good, free antivirus utilities out there. If you have an antivirus installed, then run a computer scan.

You can also try temporarily disabling your antivirus. Maybe he changed some network settings, and the pages in the browser stopped opening.

Think, maybe the problem appeared after installing or removing some program. Or changing some parameters. So you can find out at least an approximate cause of these problems.

If I remember something else, or learn something new about this problem, I will definitely update the article. You also share your experience in the comments, write about working solutions. You can leave your questions.

There are several reasons why there is Wi-FI without access to the Internet.

Often problems lie in routers and access points, but there are also cases when services installed in the operating system are to blame for the malfunction.

How to recognize the cause of the problem, read on.

Determining the problem

First you need to find out at what stage of the connection the problem arose.

In order to make sure that the problem is with the router settings, you must try to connect to the Wi-FI network through another Windows laptop or smartphone.

If the error disappears and the Internet connection is present on another device, the user will find out that it is necessary to configure the Wi-FI adapter in the laptop itself.

In the event that access to the network was not obtained from any device, it will be necessary to look for problems in the router, access point, modem or Internet provider.

It is also worth trying to connect the network using a network cable, bypassing routers. This will allow you to identify problems more specifically.

If there is access to the Internet via cable, then it is worth changing the settings of the router or access point itself, if not, the problem is in the modem (if any) or provider.

Disabling network access on the provider side

Sometimes, for reasons of malfunction or maintenance, a yellow triangle can be observed, which notifies the user of a limited Internet connection.

In the case when the equipment settings were not performed, but access, nevertheless, was lost, most likely the problem is on the provider's side.

In this case, you need to find the company's phone number, which is usually recorded in the contract, and, by calling, inquire about the causes of the malfunction.

Advice! But do not immediately rush to dial the operator of your provider, first reboot the router, since technical support will offer to do this in the first place.

If the resource is loaded and access to your personal account is obtained, this will mean that the Internet connection is limited by the provider intentionally, possibly for non-payment.

In the event that the site does not work, it is worth going to a call to the technical support operator.

Operating system settings

If access points are visible in the system on a laptop, you will not need to reinstall the driver.

When the Wi-Fi adapter is successfully connected to the network, but there is a yellow triangle in the system tray, indicating a limited Internet connection, it is necessary, which, if configured incorrectly or if they fail to work, can cause a similar problem.

The best option to check the health of the Internet, it will boot the system on a laptop in safe mode with support for network drivers.

To do this, you need to go to the system settings by pressing the key combination in Windows "Win + R" and run the msconfig request.

This will open the System Configuration window. In it, you need to go to the "boot" tab, where you need to mark "safe mode" with the "network" parameter.

If with this option you have access to the Internet, you need to start the laptop in normal mode, removing the previously set parameters, and then turn off applications that affect the network one by one.

Most likely, these may be recently installed or updated programs.

The best option for this is Dr.WebCureIt! For Windows, since it does not require installation, it is free and always contains an up-to-date database.

Setting up a router

If Internet access is not available on several devices, the problem is in the settings of the router, which distributes the connection incorrectly.

It can occur when resetting the settings for the current provider.

To restore them, you will need to open the description for setting up on the website of the company that provides the Internet.

Also, all the necessary parameters for entering into the router are often attached to the contract concluded when connecting services.

In the event that the router was purchased independently of the provider, the instructions for it, most likely, will not be present on the site.

It will need to be found on the resource of the equipment manufacturer. Also, the documentation is always present in the box with the router.

The sequence of actions for making settings on the D-Link DIR-600 router:

• open the parameters by entering its IP into the address bar of a Windows browser or other OS;

• enter your username and password (the default value is admin);
• set the name and password in the wireless network wizard WiFi connections;

WiFi network name

• by going to the tab in the lower horizontal menu "Advanced settings", click on the WAN item, located in the network section;
• if there is a connection profile, double-click on it to make settings; if it is missing, add a new one.

• in the window that opens, make and save the settings that are specified on the manufacturer's website.

Also, for this router model, a simpler configuration option is available by clicking the Click’n’Connect item in the main menu.

However, it may not work correctly with some providers.
