Everyone faces this problem, and, unfortunately, this rock comes sooner or later. You should not be afraid, since, in particular, the problem is still being solved, although there can be a lot of reasons for it. And so, you cannot go to any site, but in the lower right corner it says - "Without access to the Internet" or "without access to the network", and you behold the yellow triangle. We will not go around and around, and we will analyze all possible solutions - let's start with the most popular ones.

HELP! Dear readers, you can always write your question or describe your problem below in the comments. And I will try to help you as much as I can.

How to fix - quick fix

What's the first thing to do? If Internet packets are distributed over a wireless Wi-Fi network and it suddenly disappeared, then the router may have turned off. This happens on old, worn out routers that have been working for more than one year. Our task is simply to reboot the device. This can be done in two ways:

1. We find on the back panel the ON / OFF or ON / OFF button. Press once, wait 5 seconds, turn it on.
2. We unplug the power cord from the socket and after 5 seconds plug it in again.

Sometimes a router is needed only for distributing a Wi-Fi network, and access to the World Wide Web goes through a modem. So, just in case, reboot it too.

My old router was buggy every 2-3 days. It's just that he was already old and his time had come to an end. Soon I bought a new one. So, if this problem is repeated often, then get a new device.

Checking the physical connection

It doesn't matter whether you have a computer or a laptop, if the wire goes straight, then look at the light on the network card blinking or on. Also make sure that the lamp on the LAN port indicator is on. Let me explain more clearly - almost every router has an indicator.

When you insert a wire into one of the LAN ports and data is being exchanged, the indicator is on or flashing. The indicators are located on the front of the machine. Take a look at the photo below - 1 LAN port is connected to the PC and works stably.

If the light is off when physically connected, then most likely the cable is broken. In the box from under the router, there should be a factory wire, you can safely use it.

Another problem is when the wire from the Internet is stuck in the wrong place. Take a look back and see that the cable from the ISP was in the internet connector. A friend once had a daughter playing with a router and stuck wires in the wrong connectors, and therefore there was no Internet. If the router does not light up at all, then there is already a problem with the power supply, try turning it on.

The surest way is to joke the wires and see that they are clearly in the port. Once my Internet was disconnected, because the eyelet from the plastic tip of the wire fell off, because of which the wire simply came off. In this case, good old matches will help. But nevertheless, it is better to re-crimp the end or change the cable.

Network settings

In the case of a Wi-Fi connection, the problem may lie elsewhere. In 20% of cases, the network settings on the PC do not allow access to the Internet. The principle of changing the configuration is the same as on Windows 7, XP, 8, 10 and Vista.

1. You need to click on the yellow triangle in the lower corner, and then select Network and Sharing Center.

1. Next, select from the left block - "Change adapter settings".
2. Usually, a stationary PC has one network card, and on laptops there are two connections: wireless and LAN. Make sure the connection you are using is turned on. When the configuration is disabled, it will be highlighted in gray. To enable, press the right button and "Enable".
3. Right-click on the desired connection and then in the "Property".

1. Click once on Internet Protocol Version 2 (TCP /IPv4) ". And then on properties.

1. Pay attention to the picture above. There is a permanent IP address in the settings. Also, the subnet mask and the default gateway are directly spelled out (must be our router). Therefore, there are two options for inoperability in the network:
   1. If someone else is using the Internet, then most likely this IP address is already being used by another computer, phone or network printer.
   2. The second option is that the router is on a different subnet.
2. There is only one solution, just put a tick in front of Obtain an IP address automatically and "Obtain DNS server address automatically".
3. We confirm the configuration and look at the result.
4. In case of further network absence, go to the settings again, check the box "Use the following DNS server addresses"And prescribe:
   1. Preferred DNS Server: 8.8.8.8
   2. Alternative DNS Server: 8.8.4.4
5. Next, the Internet should be connected. If this did not immediately help, then after changing the configuration, restart the computer or laptop.

Installing FIPS

1. If you have a laptop, and the connection is via a WiFi network, click on it in the right corner of the desktop.
2. Then we press "Properties".
3. Click on the second tab from the left with the name "Security".

1. Click on the button at the very bottom - "Extra options".
2. We put a mark "Enable for this network the mode of compatibility with the Federal Information Processing Standard (FIPS) " and confirm the change . After that, we restart the computer or laptop.

Resetting DNS communication parameters

1. We start the command line. To do this, in the start menu in the search bar, enter cmd.
2. Right click and "Run as administrator"... If you just start the console, no changes will be made.
3. Next, we enter the commands one by one:
   1. ipconfig / flushdns
   2. netsh winsock reset
   3. netsh int ip reset c: \ resetlog.txt.
4. Now we reboot the machine.

Software and breakdown of network card drivers

Drivers can break from viruses or third-party programs that work with network protocols. It is very popular to use WPN programs that can establish additional network connections.

1. Press WIN + R, enter ncpa.cpl and press OK.
2. See if there are any suspicious connections that weren't there before.
3. If they are, then disable them by right-clicking - "Property" and press "Switch off".
4. After that, even if the Internet and the network are working, you need to remove the conflicting program.
5. We go to Start.
6. Next, select "Control Panel" and go to the programs.

1. Sort by installation date and see the latest installed programs. Sometimes the installation can take place in the background while loading regular programs.
2. Remove suspicious software by right-clicking and "Delete".
3. We reboot the computer.
4. It is not a fact that everything will start working, since the program could break the driver for the network card. The fastest way is to restore the system. To do this, go to "Start" - "All Programs" - "Standard" - "Service"... We choose " System Restore".
5. Pick the earliest point possible and start the service. After rebooting, the system should display a successful recovery window. If you see an inscription that the system has not been restored, then you will have to look for the driver on the Internet, download it, and then install it on your PC. If you still have a disk with drivers from the motherboard, then you can install from there.

The system can break not only from third-party software, but also from viruses. So be sure to install the latest antivirus and scan your entire computer for dangerous and suspicious software.

ISP

In 80% of cases, this problem lies on the shoulders of the provider. Be sure to call and find out what the problem is.

After dialing, they usually say that technical work is underway or breakdowns in the channel. But sometimes, they can say that everything is fine with them. Ask the employee of those. service check the connection from the server to you.

If that doesn't help, ask which DNS is best to use. You already know how to change them from the chapters above. If all else fails, then perhaps the cable is cut off on your line at the entrance, then you will have to call the worker at home to check the line.

Different subnets

Sometimes a problem with the Internet connection is due to the fact that the computer and the network adapter are on different subnets. This often happens in offices when a new machine is connected to the subnet.

1. First, we need to find the IP address of the router. According to the standard, they are 192.168.1.1 or 192.168.0.1. I personally have 192.168.1.1.

NOTE! The standard address of the router can be found on the label under the device.

1. You need to go to the network settings and see what is there. In any Windows, press two keys WIN + R at the same time. We register the ncpa.cpl command and click OK.

1. Next, you need to view the properties of the IPv4 connection.

1. Please note that the computer's IP address is 192.168.5.123. And the address of my router is 192.168.1.1. They are located on different subnets and do not see each other. My PC is on the 5th subnet, and the router is on the 1st.
2. Next, it is best to put automatic IP and DNS detection, as in the picture below.

Configuring the router

Once there was such a case when children, playing with an interesting box, reset the router settings to the factory settings, and then no one could understand what the problem was. Sometimes it happens that the settings themselves got lost and they need to be adjusted or corrected. The most important thing is to take and keep next to the contract with the provider, which specifies the connection settings.

1. It is best to connect your router directly if it is not. Take a regular wire and plug one end into one of the LAN ports, and the other into a network card.
2. Now you need to go to the admin panel of the router. To do this, open any browser and register the IP address of the router. By the standard, this is usually either 192.168.1.1 or 192.168.0.1.

1. Enter your username and password. By factory standards, these are admin, admin, if you haven't changed them. The instructions below will differ slightly from the operating system of the router.

TP-Link

I'll tell you on the example of the TP-Link Wireless N Router WR841N model, which is the most popular in the Russian Federation and the CIS countries.

1. In the left menu, select "Network", and then click « WAN ".

1. Click on the connection type and select the one that your provider uses: Static IP-address, PPPoE, L2TP / L2TP, PPTP / PPTP, BigPont cable.
2. Further, depending on the choice, you must enter data from the provider from the contract or by calling the hotline number in those. support.
3. If you are at a loss with the settings, then click "Quick setup" in the left menu and just follow the instructions.

ASUS

1. In the lower left menu, select "Internet".
2. We choose the type of connection in
   1. We enter the settings. You can also click "Fast Internet Settings".

   Other models

   The scheme is basically the same:

   1. In the main menu we find the section "Internet" or "WAN" and click on it.
   2. We select the type of connection that your provider uses:
      1. Automatic IP detection- this connection is usually installed in the machine. Here we just set this parameter and the Internet should appear.
      2. PPPoE- here you need a login and password for access. You may need to specify the associated MAC address. If this is your PC, then click clone this parameter.
      3. Static IP- here you need to specify the external IP, subnet mask, default gateway and DNS servers.
      4. L2TP or PPTP- we specify the static connection data, login, password and DNS.
   3. We enter the settings from the contract.
   4. Don't forget to set up your Wi-Fi.
   5. We apply them and reboot the router - by turning it off and on.

   ADVICE! To know how to set up the Internet and Wi-Fi for your model, just use the search on our website. To do this, enter the full name of your router and follow the instructions in the article. There is nothing complicated there and everything is written very clearly.

If some providers do not support the ipv6 protocol, and the protocol is not used in conjunction with a router, then ipv4 is directly responsible for the presence of the Internet. Therefore, in this article we will look at how to troubleshoot when the "ipv4 without Internet access" error appears.

Why ipv4 error occurs without internet access

When a user uses the Internet, the chain consists of three segments - provider, network and user equipment. Failures or problems in one of the listed segments, and lead to the lack of the Internet. And troubleshooting a router or computer will not fix the problem if the provider has a problem. Therefore, to save time and effort, it is important to understand and identify the problem segment.

The best way to define it is to exclude the unnecessary:

1. Call the operator and make sure of the correct provision of services at your address.
2. If you are using a router, check the operation of the local and wireless network by connecting other devices. If there are no restrictions on the part of the provider and operability with other devices, the problem should be looked for in the main computer.
3. Connect the internet cable to the network card of the main computer. In the absence of restrictions on the part of the provider and the operability of the Internet, the problem should be looked for in the router.

Another way is OS diagnostics.

If the error occurred due to the fault of the provider

Contact your internet provider to find out why the connection is missing. In the event of an accident or scheduled maintenance / replacement of equipment, the provider is obliged to inform the deadline for completion of the repair work. If the network cable is damaged, request a replacement technician.

In apartment buildings, the provider's equipment is located primarily on the roof. In the event of a power outage or power failure, the equipment is turned off. After power on, it usually takes 5-10 minutes to turn on. Sometimes a reboot of the computer / network equipment is required to resume work. Also, disruptions in the Internet supply can be observed during thunderstorms.

If the error occurred due to the router

Before proceeding to find and eliminate the probable cause, make sure that the network equipment is connected correctly. When connecting wires, it is important not to confuse LAN and WAN ports. Sometimes the network cable is loose in the WAN connector. Therefore, it is important to check the tightness of the connection.

Solution 1: check your connection settings

Open the control panel of your router and go to the network settings. Make sure that the WAN connection type is set correctly, and the parameters are set in accordance with the requirements of the provider.

Also open DHCP settings. The server must be turned on. The starting IP address is 192.168.1.100, the ending IP is 192.168.1.199.

Solution 2: reset settings / change firmware

Sometimes the router refuses to save the entered settings. In this case, resetting and reconfiguring helps. Sometimes you need to replace the firmware, in rare cases, replace the router itself.

If an error occurs on the computer

Solution 1: check the connection settings / manually register the gateway address

1. Open network connections, where select the properties of your internet connection.
2. Select the ipv4 protocol and then open properties.
3. Make sure the settings are correct. If you are connected via a router, use automatic retrieval of parameters.

Sometimes the DHCP server does not broadcast the gateway address. In this case, you need to register the gateway manually. The provider will give you the necessary data when you contact us.

Also try to specify the automatic acquisition of the IP address. Specify in the DNS server values:

The preferred is 8.8.8.8.

Alternative - 8.8.4.4.

Solution 2: disable or change firewall settings

If the message "ipv4 without Internet access" appears after installing an antivirus or firewall, or tampering with the settings, then temporarily disable the programs.

Sometimes you want to disable the built-in Windows Firewall. To do this, open the control panel, then "system and security". In a new window "Windows Firewall", and then "Turn Windows Firewall on or off."

Solution 3: turn off energy saving features

Active power saving modes contribute to the temporary or permanent shutdown of the Internet. Therefore, it is necessary to recheck and disable the corresponding functions.

Power supply mode

Open Power Mode as shown in the images below.

Select balanced or high performance mode.

If you made changes to the plan, reset the settings to their original state.

Additional network card parameters

In Control Panel, select "System and Security".

In the "System" section, select "Device Manager".

Find "network adapters" in the list.

Open the properties of the network card.

Under the Advanced tab, find green and energy saving features. In the meaning of each item, select "disable".

Output

If you get an ipv4 error without internet access, make sure that the problem is not on the ISP's side. Disconnect the router to avoid problems with the network equipment. If the problem is related to the computer, manually set the IP address and DNS server parameters, or use automatic or semi-automatic parameters, for example, only specifying the server addresses. Also disable the power saving functions to prevent internet disconnection.

This problem exists and has affected many users. Its essence is as follows: a Wi-Fi router is purchased, it is connected and configured, but the Internet is still missing and the Internet is not distributed to remote devices. A network without access to the Internet is a situation with a variety of reasons:

• The router may be malfunctioning, which is quite rare, but it still happens.
• The router may not be configured correctly.
• WAN usage may be limited by your ISP. For example, if you are late in payment for services.
• The problem might be with your computer or laptop.

And some others. A network without Internet access can be tested on different devices. In the event that the Internet is absent when different subscribers are connected to the router, this means that the problem should be looked for in the router or find out if the network is limited by the provider.

The latter is especially easy to do - you just need to call the operator by phone. But more often than not, a network without Internet access is caused by incorrectly configured router settings. Further we will begin to consider just such a situation.

How does the picture look in practice?

Below is a figure showing a typical grid pattern without Internet access:

All this does not depend on the router model at all, but is only a consequence of incorrect settings. To begin with, such settings must be "reset" - that is, to transfer the router to the state in which it was immediately after leaving the conveyor. Each such device has a button labeled "Reset". It can be located either on the side of the device body or on its rear wall.

Typically, the button is small. This is done to prevent accidental pressing. Another protective measure is the need to hold the button down for some time (usually about 10 seconds). This is the only way to achieve its triggering. So, take an object with a sharp tip and press the button with it, holding it for a while. The signal that the settings have been reset will be the multiple blinking of the front panel lamps.

For beginners, the following figure may be helpful:

It shows the correct connection of the ISP cables, interconnect cable, and power supply cord. Check if the connection of your router matches what is shown in this figure.

Is the connection type correct?

Among the software settings of the router, there is one parameter that is critical for the normal functioning of Wi-Fi. This is a type of Internet connection. If you specify the wrong type of connection, access to the Internet becomes impossible. If, when the router is physically connected to the computer, when configuring the router, Windows says "without access to the Internet" - first of all, check the type of connection. this parameter can take the following values:

• PPPoE.
• L2TP.
• PPTP.
• Static IP.
• Dynamic IP.

Each of the connection types has its own settings. You should ask your provider what kind of connections it uses to connect subscribers. Connecting to the network using a dynamically assigned address looks the most elementary.

In this case, you do not need to specify any additional parameters, such as an IP address, gateway addresses, etc. PPTP, PPPoE and L2TP usually require a username and password assigned to you by your ISP. These data are usually specified in the connection agreement. Static IP will require specifying the IP address itself, the gateway address and DNS addresses in the router settings. They must match those of the computer connected to the device. It is not difficult to find out all these parameters by typing the command in the Windows console: ipconfig / all.

MAC Binding

This is a common technology for identifying users by the provider. Each network device is assigned a unique identifier - the so-called MAC address. When connecting, the provider can control this parameter and, if it does not comply with what is stated in the contract and the provider's internal database, reset such connections. Many have encountered this situation when reconnecting the provider's cable to another computer or laptop. In this situation, you have to manually register the MAC address in the Internet connection settings.

Roughly the same has to be done when connecting to the router's network. To do this, in its settings there is a special interface, usually equipped with a button labeled like "Clone MAC Address" or something like that. If you have correctly specified the type and parameters of the network connection, and you still cannot connect to the Internet, try cloning the MAC address. Or call the provider with a request for advice on this matter. Details may also be found on the website of your ISP.

How do you find out the value of the MAC address of your computer? With the above command: ipconfig / all. The list of its output also contains such information.

Other possible causes of the problem

Be sure to check the network on a computer with a directly connected ISP cable (that is, without using a router). You may have incorrectly configured the network settings on the computer itself.

If the network is lost or there is no access to the Internet, this may be the result of a broken cable from the service provider or a malfunction of the house equipment responsible for distributing the network to apartments. In either case, the router has nothing to do with it, but you need to check all the options.

If you are using a configuration from an ADSL modem and a router, then in the settings of the latter, write down a dynamic IP address, regardless of the provider's technology. All necessary parameters must be specified in the ADSL modem settings.

Check the correctness of the Internet settings on the devices connected to the router. Incorrectly specified settings can also cause the message "connected, but no Internet access".

The network signal can also drop for other reasons. For example, you may find that there is no wireless connection, and when you connect devices with a cable, the problem disappears. It can also be due to various reasons. The simplest of them is that the signal does not reach the subscriber due to the presence of obstacles in his path. Alternatively, the signal can be damped by external devices operating at the same frequency as the router.

Loose connection of the provider's cable to the router connector can also cause the devices to work without access to the Internet. On the body of any good router there is a special light that signals insufficient contact.

Another possible cause of network failures is a problem with Windows or another operating system installed on the subscriber device. This should also be borne in mind when the error we are considering appears. To detect such failures and eliminate them, you can try using the tools built into Windows: "Diagnostic Center":

Remember, you need to set everything up carefully and as competently as possible. If our information on what to do when working without access to the Internet turned out to be useful to you and the Internet is there, then we can consider our task completed. But it may turn out differently: I connect, but writes that the network works without the Internet - try to write to us about this, providing detailed information - we will show you how to fix it.

The first setup of a 4g MTS modem is both simple and skill-requiring. Such a unit is intended so that you can go online where it is needed and when there is no access to the wired Internet or does not catch Wi-Fi. MTS 4G network coverage covers a large area, so there should be no problems with communication. It is a small block that plugs into a USB connector like a flash card. Agree that it is very convenient to have it at hand? The device does not take up much space and easily fits into a laptop bag or just in your pocket.

To get started, it is enough to perform a small setting that can activate the 4g MTS modem. The interface of most programs is designed in such a way that it is not at all necessary to have special knowledge in the field of computer science and programming. During installation, the program does everything autonomously, all you need to do is give your consent to the actions performed and specify the path to save the files.

Let's take a closer look at how to properly install a 4 g MTS modem on a computer. It is worth noting that the basic kit includes the device itself, instructions for it and a SIM card. To broaden your horizons and compare, you can still read about.

How to connect a 4g MTS modem to a computer

Initially, you should, as you already guessed, insert the sim card into a special slot. The device will work in the LTE network only with the sim card that comes with it. When installing another sim card, it will work in the 3g network and the speed, accordingly, will be lower than the declared one. Here you can find out, perhaps it will be more relevant for you.

How to set up a 4g MTS modem

After preparing for work, you need to insert the device into a computer or laptop. The operating system automatically detects and recognizes the new hardware, and then activates the installation wizard itself. If this did not happen, then you need to go to the "Start" menu, then go to the "Computer" section. The USB dongle will appear as a removable disk because it is configured with a Micro SD card slot. Installing a memory card just allows us to use it as a removable disk.

• Open the drive and double click on the Autorun.exe file,

• Then follow the prompts that will pop up on the screen from the installation wizard.

• Run the program shortcut "Connect Manager", which will be displayed after installation on the desktop.
• When the modem is registered on the Internet, click on the "Connect" button.

• First, in the device selection section, the message "MTS-connection is not connected to the network" will appear. Don't worry, wait for the connection. Immediately after establishing a connection to the Internet, the message "MTS-connect is connected to the network" will pop up in the device selection menu.
• In the "Connect" section, click the "Disconnect" button to suspend the Internet connection.

Additionally, in the Connect Manager application, you can also send SMS, activate a payment card, check the current balance and the balance of the megabyte package.

MTS settings for 4g usb modem with wifi router function

All Wi-Fi equipment in the house, be it a smartphone, TV, tablet, refrigerator, and much more can be hooked up to the World Wide Web using a flagship with a wifi router function. You can connect such a 4g MTS modem to a power adapter or a PC and start up no more than 10 devices at the same time using it.

The installation process will depend on the operating system of your computer. Let's take an example installation for Windows XP:

• Insert the device into the USB port;
• Follow the steps requested by the installation wizard;
• If you have any difficulties with automatic configuration, manually run the AutoRun.exe file;

• Open the address of the router settings in the browser (they are on the device itself). Then enter the standard name and password - admin;

• Check access point settings- the mark is not used by default should be unchecked;
• Make sure that other devices do not work to distribute a signal, this can lead to a malfunction of all modules.
• If you still can't get online, try restarting your computer.
