Today, many subscribers are happy owners of a modem from MTS. This is not surprising, since in modern world It's hard to get by without the internet. Not everyone is able to use local network, and sometimes a modem is much more convenient, because it is mobile, you can carry it everywhere with you.

The MTS Connect set is a complete set for accessing the network. It has a modem, sim card and user manual. Each subscriber can choose the most favorable and convenient terms of service, because the company has developed many tariff plans and options that take into account the maximum needs of subscribers. With the help of MTS Connect, you can always and everywhere be in touch using modern 3g and 4g coverage. However, for correct operation equipment must be properly connected. What to do if you can't connect? It is necessary to understand in detail.

The MTS Connect set allows its owner to use access to the network anywhere where there is an operator coverage. To use the Internet, you can only use a SIM card with a connected Connect, and use it as a modem mobile phone. But in any case, the modem or smartphone must be configured correctly.

To set up the equipment you need:

  • desktop computer or laptop;
  • modem or smartphone;
  • SIM card with MTS Connect;
  • operator coverage.

First of all, the modem with a SIM card must be connected to the computer in any USB port. After that, the drivers and the Connect program will be automatically downloaded to the computer. If the computer is located in a zone with 3g coverage, then to access the network, you only need to press the button to connect. After all, the modem is already configured by default.

If the mts connection is not connected to a high-speed 3g network, most likely the equipment is outside the high-speed Internet coverage area, or the 3g signal is not stable. In this case, you need to change the network settings. This menu item is called that, in it you need to go to the network and change the priority.

After all the changes made, it is necessary to restart the operating system. Only in this case the equipment will work correctly.

No access

As it has already become clear, the first thing to do when the 3g network is not available is to try to connect to less high speed internet. However, it happens that the subscriber, even after changing the priority, cannot access the Internet. In this case, the first thing to do is to update the driver or replace the hardware firmware.

The next step is to reinstall the program. To do this, you need to disable the modem and delete all installed drivers. After that, you can reconnect. It's also worth scanning. hard drives with help antivirus programs, because computer infection can also cause incorrect modem operation. It is not superfluous to check the stability of the network signal reception by the modem.

The main problem of the inability to access the Internet, no matter how trite, is the lack of funds on the balance sheet. To avoid this problem, the state of the account must be kept under control and replenished on time.

Everyone faces this problem, and, unfortunately, this fate 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 can’t 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 will see a yellow triangle. Let's not beat around and around, and sort everything out 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 Solution

What to do first? If internet packets are distributed by wireless network Wi-Fi and it suddenly disappeared, then the router may have turned off. This happens on old, already worn 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 the ON / OFF or ON / OFF button on the back panel. Press once, wait 5 seconds, turn on.
  2. Unplug the power cord from the outlet and plug it in again after 5 seconds.

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

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

Checking the physical connection

It doesn’t matter if you have a computer or a laptop, if the wire goes straight, then look at the blinking or lit light on the network card. Also make sure that the light on the LAN port LED is on. I will explain more clearly - on almost every router, there is an indicator.

When you insert a wire into one of the LAN ports and data is being exchanged, the indicator is on or blinking. 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 at physical connection If the light doesn't come on, the cable is most likely 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 plugged in the wrong way. Look back and see that the cable from the provider was in the internet connector. A friend's daughter once played with a router and plugged the wires into the wrong connectors, and therefore there was no Internet. If the router does not light up at all, then the power supply is already a problem, try turning it on.


The surest way is to screw up the wires and see that they stand clearly in the port. Once, my Internet went offline, because the eyelet fell off the plastic tip of the wire, because of which the wire simply moved away. In this case, the good old matches will help. But still, it is better to re-compress 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 network settings PC won't let you connect 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 bottom corner, and then select "Network and Sharing Center".
  1. Next, select from the left block - "Change adapter settings".
  2. Usually on a stationary PC there is one network card, and on laptops there are two connections: wireless technology and over LAN. Make sure the connection you are using is enabled. If the configuration is disabled, it will be highlighted in gray. Press to turn on right click 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 properties.

  1. Pay attention to the picture above. In the settings there is a permanent IP address. Also directly registered are the subnet mask and the main gateway (should 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 "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 absence of the network, go back to the settings, check the box "Use the following DNS server addresses" and write:
    1. Preferred DNS Server: 8.8.8.8
    2. Alternate DNS Server: 8.8.4.4
  5. Next, the Internet should be connected. If this does not help immediately, then after changing the configuration, restart the computer or laptop.

Installing FIPS

  1. If you have a laptop, and the connection is via WiFi networks- 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 "Safety".


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

Reset DNS communication settings

  1. We launch command line. To do this, in the start menu in the search bar, type cmd.
  2. Right click and "Run as administrator". If you just run the console, no changes will be made.
  3. Next, 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 broken network card drivers

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

  1. Press WIN + R, enter ncpa.cpl and click 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 programs.


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

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

Provider

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

After dialing, they usually say that they are being engineering works or breakage in the channel. But sometimes, they may say that everything is fine with them. Ask a tech worker. services 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 the cable may have cut off on your line in the entrance, then you will have to call a worker to your house to check the line.

different subnets

Sometimes a problem in connecting to the Internet is due to the fact that the computer and 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 into the network settings and see what is there. In any Windows, press two keys WIN + R at the same time. We write the ncpa.cpl command and click OK.


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


  1. 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 located in the 5th subnet, and the router is in the 1st.
  2. Next, it's best to set automatic IP and DNS discovery, as in the picture below.

Setting up a router

Once there was such a case when children, playing with an interesting box, reset the router settings to factory settings, and then no one could understand what the problem was. Sometimes it happens that the settings themselves have gone astray and they need to be adjusted or corrected. Most importantly, take and keep nearby the contract with the provider, which specifies the connection settings.

  1. It is best to connect the router directly if this is not the case. Take a regular wire and plug one end into one of the LAN ports, and the other into the network card.
  2. Now you need to go to the admin panel of the router. To do this, open any browser and enter the IP address of the router. By standard, this is usually either 192.168.1.1 or 192.168.0.1.
  1. Enter login and password. By factory standards, this is admin, admin, if you have not changed them. The instructions below will differ slightly depending on the operating system of the router.

TP Link

I’ll tell you using 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 "Net" and then press « 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 need to enter data from the provider from the contract or by calling the number hotline in those. support.
  3. If you are having trouble 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. Select the type of connection in
    1. We enter the settings. You can also click "Quick 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. Select the type of connection that your provider uses:
      1. Automatic IP detection- this connection is usually in the machine. Here we simply set this parameter and the Internet should appear.
      2. PPPoE- Here you will need a username and password to 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- specify the static connection data, login, password and DNS.
    3. We enter the settings from the contract.
    4. Don't forget to set up wifi.
    5. We apply them and reboot the router - turning it off and on.

    ADVICE! To know how to set up 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.

How to set up an MTS connection on your home computer laptop or tablet? We strongly recommend that you buy USB modems exclusively at the official offices of MTS, since buying such a device in other places may have a completely different effect than you expected. One of the problems may be the fact that you will not be able to connect to the MTS network at all and get high-quality Internet access. Also, before buying, you should understand why you need an MTS connection. Some people need it for quick search necessary information on the Internet, while they will use it for a short time during the day. Other MTS subscribers need a connection for long-term use during the day, for watching a lot of video files, as well as listening to music. In other matters, which tariff to choose is entirely up to you.

Setting up MTS Connect

Finally you have decided on tariff plan and purchased an MTS connection, how to set it up. First, unpack this device, namely the USB modem. Initially, all the necessary software, drivers for the device, as well as all settings are already in internal memory USB modem. To set up an MTS connection, you need to insert a USB modem into the USB socket on your personal computer laptop or tablet, the installation will start automatically. The only thing you have to do is click on the next and ok buttons in the pop-up windows. Of course, the ideal MTS connection setup will happen on modern computers with official operating systems installed on them, such as Windows 7 and Windows 8. Windows XP owners may have to tinker with the search the right drivers on the official website of the MTS company.

Necessary MTS Connect settings

It happens that a USB modem from MTS that works on 3G technology does not work. You may be in an area where the transmission tower is operating in an outdated mode. To solve this problem, we recommend that you go directly to the Content Manager program that you have installed on your computer or laptop. Next, go to the options and click on the network, then select WCDMA Priority. This will give your USB modem the ability to work in 2G mode. If the information in this article did not help you, it may be outdated, and we recommend that you go to the official website of MTS.

Using USB modems is easy and simple. Installation of drivers and software occurs automatically after connecting the modem to the computer and takes a minimum of time. Ingoda, however, still requires some participation in the user's process. But first things first.

Remove the cover from the modem and insert the SIM card into the slot. Close the cover and plug the modem into the computer's USB port.

The operating system should automatically detect and recognize the new device and start installing the drivers. All information is displayed in the taskbar in the form of pop-up messages.

After installing the drivers, the software installation will begin. When the software autorun window appears, start the installer wizard by clicking the "Run AutoRun.exe" button.

If the installation wizard does not start automatically, locate the AutoRun.exe file and run it manually. To do this, open "My Computer" and the CD-ROM drive with the Connect Manager program recorded on the modem's flash memory, and double-click on AutoRun.exe.


In the installation wizard window that opens, select the desired language, click OK, and follow the installer's instructions.

After installation is complete, launch Connect Manager using the desktop shortcut. A few seconds after launch, the program will detect the presence of a signal. Pay attention to its strength, characterized by the indicator in the upper right corner of the window.

For some modem models, the signal strength depends on their orientation in space. If the signal is not strong enough, you can try connecting the modem through a cable that will allow you to change the orientation of the modem. After each position change, it takes a few seconds for the modem to display the signal strength corresponding to the new position.

All necessary settings USB modems are installed by default. To access the Internet after starting the program and detecting a signal, you just need to press the "Connect" button in the "Connect" menu. Establishing a connection is accompanied by a melodic sound signal and the advent of graphical display of traffic.


For manual setting modem, you need to open the "Settings" menu. In the "Network" option, you can set the network and signal format - EDGE / GPRS or 3G. The default setting is automatic network and signal selection. To set the parameters manually, you need to right-click on the network name (MTS RUS 3G in the figure) and select the "Manual" option. After that, the signal will be scanned and a list of all networks fixed by the modem will be displayed. It remains to select the required one (MTS RUS 3G in our case) and click "Select".


In the "PIN Operations" option, a request for entering a PIN code is set. It is not required by default.


In the “Modem settings” option, the APN access point (internet.mts.ru), dial-up number (*99#), password (mts) and login (mts) for connection are set. The password and login fields can be left blank.


In addition to the "Connect" and "Settings" options, the program also contains the "SMS", "Balance" and "Calls" options. From the Calls menu, you can voice communication. To do this, you will need a headset with a microphone and headphones or speakers with a microphone.


From the Balance menu, the current balance is checked. To do this, click on the "Check balance" button.


The "SMS" menu is used to send and check incoming SMS.


Some additional settings modem can be done in the "Device Manager". To do this, open the "Control Panel" and launch the "Device Manager". Right-click on the modem (in this case ZTF Proprietary) and select "Properties".

The MTS Connect kit, which includes a USB modem and a SIM card, allows its owner to use unlimited internet wherever there is an MTS coverage area. Instead of a ready-made kit, you can use only one SIM card with the MTS Connect tariff, and connect your own mobile phone to your computer as a modem. In any case, for the most efficient operation, the connection will need to be configured.

You will need

A computer;
- SIM card with MTS Connect tariff;
- MTS USB modem or mobile phone;
- MTS coverage area.

Instruction

Insert the modem into any available USB port on your computer. The modem drivers and the MTS Connect management program (in new versions - Connect Manager) will be automatically downloaded to the computer. If your area has a stable 3G coverage area (this will be seen from the indicator), to access the Internet, it will be enough to simply click on the “Connect” button after starting the program, since all the settings necessary for this are already in the program by default.

Change network settings if 3G coverage is not available or is unstable. To do this, select the “Options” item in the menu of the same name, and in it the “Network” item (in the Connect Manager program, you will need to click the “Settings” button for this).

Set the connection type to "WCDMA Priority" if the 3G coverage area is unstable, or "GSM only", if there is no 3G at all (in the Connect Manager program - "3G Priority" or "EDGE/GPRS only", respectively).

Set the parameters for connecting to another network if you intend to connect to it using the MTS Connect kit. To do this, select the "Profile Management" - "New" item in the "Options" menu and enter all the data necessary to create a new connection in the appropriate fields (in the Connect Manager program, to change the profile, select the "Modem Settings" item).

Enable/disable automatic start of the control program at the same time as Windows starts.

Choose save options incoming SMS. Optionally, you can also set your ringtones for calls and messages.

Use your phone as a modem. To do this, connect it to your computer in any way convenient for you - via data cable, bluetooth or infrared. Install drivers if necessary.

Set up the received modem. To do this, in the Control Panel, select the "Phone and Modem" item. In the window that opens, select your phone in the list of modems and click on the "Properties" button.

Open the "Advanced communication settings" tab and enter in the "Advanced initialization commands" field:

AT+CGDCONT=1,"IP","internet.mts.ru"
Click the OK button to save the settings.

Create a new remote (dial-up) Internet connection. In the parameters of this connection, specify:
mts username
mts password
call number *99#
You can find more information on creating a new connection for your OS on the MTS website http://www.mts.ru/help/settings/gprs_edge/.

This problem exists and many users have been affected by it. Its essence is as follows: it is acquired wifi router, it is connected and configured, but the Internet is still missing and the Internet is being distributed remote devices not happening. A network without Internet access is a situation that has a variety of causes:

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

And some others. A network without Internet access can be tested on different devices. In the event that the Internet is not available 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 most often, a network without access to the Internet is due to incorrectly configured router settings. Further we will consider just such a situation.

What does the picture look like in practice?

Below is a picture 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 incorrectly made settings. To begin with, such settings must be “reset” - that is, transfer the router to the state in which it was immediately after exiting the assembly line. Each such device has a button labeled "Reset". It can be located either on the side of the instrument case or on its rear wall.

As a rule, the button has a small size. This is done to prevent it from being accidentally pressed. Another protective measure is the need to keep the button pressed for some time (usually about 10 seconds). That's the only way to make it work. 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 multiple flashing of the front panel lights.

For beginners, the following figure may be helpful:

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

Is the connection type correct?

Among the software settings of the router, there is one parameter that is critical for normal functioning WiFi. This is the type of Internet connection. If you specify the wrong type of connection, access to the Internet becomes impossible. If at physically correct connection router to the computer when setting up the router, Windows writes "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 connection type has its own settings. You should find out from the provider what kind of connections he uses to connect subscribers. The most elementary is the connection to the network using a dynamically assigned address.

In this case, you do not need to specify any additional options, such as 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. A static IP will require you to specify 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 in the console Windows command ipconfig /all.

Binding by MAC address

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

Approximately the same thing has to be done when connecting to the router's network. To do this, its settings have a special interface, usually equipped with a button labeled like “Clone MAC Address” (“Clone MAC Address”) or something like that. If you correctly specified the type and parameters of the network connection, but you still can’t connect to the Internet, try cloning the MAC address. Or call the provider with a request for advice on this matter. You may also find detailed information on the website of your ISP.

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

Other possible causes of the problem

Be sure to check the network on a computer with a directly connected provider 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 due to a break in the cable of the service provider or a malfunction of home equipment responsible for distributing the network to apartments. In both cases, 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, enter a dynamic IP address, regardless of the provider's technology. All necessary parameters must be specified in the ADSL modem settings.

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

The network signal may disappear for other reasons. For example, you may find that wireless connection is missing, and when devices are connected via a cable, the problem disappears. It can also be caused by various reasons. The simplest of them is that the signal does not reach the subscriber due to the presence of obstacles in his path. Another option - the signal can be extinguished external devices operating on the same frequency as the router.

A loose connection between the provider cable and the router connector can also cause devices to work without access to the Internet. On the body of any good router there is a special light bulb that indicates insufficiently strong contact.

Another one possible reason network failures - malfunctions in Windows or other 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 fix them, you can try using the built-in Windows toolkit: "Diagnostic Center":

Remember, you need to configure everything carefully and, if possible, with knowledge of the matter. 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 available, 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 writing to us about this by providing detailed information We'll show you how to fix it.

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

Why does ipv4 error occur without internet access

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

The best way to determine is to exclude the superfluous:

  1. Call the operator and make sure the correct provision of services at your address.
  2. If you are using a router, check the operation of the local and wireless networks by connecting other devices. In the absence of restrictions on the part of the provider and operability with other devices, the problem should be sought in the main computer.
  3. Connect internet cable to network card main computer. In the absence of restrictions on the part of the provider and the performance of the Internet, the problem should be sought in the router.

Another way is diagnostics by means of the OS.

If the error occurred due to the fault of the provider

Contact your ISP and find out why there is no connection. In the event of an accident or scheduled maintenance / replacement of equipment, the provider is obliged to communicate the deadline for completion of repairs. If a network cable is damaged, request a technician to replace it.

AT apartment buildings, the provider's equipment is located mainly on the roof. In the event of a power outage or power failure, the equipment shuts down. After power on, it usually takes 5-10 minutes to turn on. Sometimes a restart of the computer/network equipment is required to resume operation. Also, failures in the supply of the Internet can be observed during thunderstorms.

If the error is due to the router

Before moving on to troubleshooting probable causes, make sure the network equipment is properly connected. When connecting wires, it is important not to confuse the 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 connection settings

Open the router control panel 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 enabled. The start IP address is 192.168.1.100, the end IP address is 192.168.1.199.

Solution 2: Factory reset/change firmware

Sometimes the router refuses to save the entered settings. In this case, a reset and reconfiguration helps. Sometimes it is necessary to replace the firmware, in rare cases, the replacement of the router itself.

If an error occurs on the computer

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

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

Sometimes the DHCP server does not pass the gateway address. In this case, you need to register the gateway manually. The required data will be provided to you by the provider when contacting.

Also try to specify the automatic receipt of the IP address. In the DNS server values, specify:

Preferred - 8.8.8.8.

Alternative - 8.8.4.4.

Solution 2: Disable or change firewall settings

If the message "ipv4 without internet access" appeared after installing an antivirus or firewall, or interference in the settings, then temporarily disable the programs.

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



Solution 3: Disable Power Saving Features

Active power saving modes contribute to temporary or permanent Internet shutdown. Therefore, it is required to double-check and disable the corresponding functions.

Power Mode

Open Power Options as shown in the images below.



Select balanced or high performance mode.

If changes have been made to the plan, return the settings to their original state.

Additional network card options

In Control Panel, select System and Security.



Under System, select Device Manager.

Find "network adapters" in the list.

Open the properties of the network card.

Under the Advanced tab, look for green and power-saving features. In the value of each item, select "disable".

Conclusion

If an ipv4 error appears without access to the Internet, make sure that the problems are not on the provider's side. Turn off the router to rule out problems with network equipment. If the problem is related to the computer, manually set the IP address and DNS server settings, or use automatic or semi-automatic settings, for example, only specifying the server address. Also, turn off power saving features to prevent internet outage.
