ABOUT MOBILE BROADBAND INTERNET

How fast is mobile broadband internet speed?

Speed ​​depends on broadband network coverage (3G or 3.5G). Even if you are in a 3G coverage area, Internet speed may vary depending on conditions, because... Mobile broadband is a wireless service (for example, nearby electrical interference may interfere with the signal). Typically, your plan description will list a maximum speed, which means the speed available in your area may be lower.

It's also worth noting that even if there is a 3G signal, using your phone as a modem instead of a dedicated USB modem may reduce the maximum data transfer speed, especially if you connect your phone to your computer using Bluetooth.

Is mobile broadband fast enough for online gaming?

Mobile broadband can be used for online gaming, but the quality of the game will greatly depend on the quality of the signal you receive. Mobile broadband typically has higher latency than fixed broadband, which can come into play if you're playing an online game that requires fast response times. To ensure smooth gaming, the time it takes for data from your computer to reach the game server and back (also known as “ping” or response time) should be between 100 and 500 milliseconds. Under good conditions, the latency of a mobile broadband Internet signal can be negligible - down to 50 milliseconds - where even high-speed shooting games are possible, but in a weak signal it can be more than 500 milliseconds, when only strategy games can be played , like "World of Warcraft".

Today for many it is already an urgent need. Modern hardware and operating systems are becoming more and more intelligent, and the user is less and less likely to need to do anything to configure. However, occasionally such a need arises. Today we will tell you how to solve the problem if your computer reports that you are connected to a network without access to the Internet, and next to the connections icon you see a yellow triangle with an exclamation mark.

Microsoft operating systems, starting with Windows 7, constantly monitor network connections, and as soon as the global network is unavailable, they immediately report it. There are many reasons why your computer may not have an Internet connection. These could be problems with the provider, incorrect equipment configuration on the part of the user, or failures in the operation of network protocols. Today, the new IPv6 protocol is becoming increasingly widespread, but its percentage is still very small, especially in home networks, so the main attention will be paid to the old version - IPv4.

Connecting via a router via a network cable without access to the Internet

Problems with the provider

Yesterday everything worked, but today this warning appeared. If this happens to you for no apparent reason, then in most cases the problem is with the provider. Therefore, before doing anything yourself, call technical support. Most often, data lines are damaged, some technical work is being carried out, or you simply forgot to top up your account on time.

You may hear in response that everything is working well with the provider, then you need to check your network and, if necessary, configure it. The support service will probably offer the services of its technician, but, firstly, his services are not free, and secondly, by the time the technician gets to you, you may have time to solve the problem yourself.

Physical connection problem

It is not so rare that the culprit is a partially broken network cable or a loose connection in the connector. And if you have pets or children, then the likelihood of such a development of events increases. Even Wi-Fi users should not forget that there will also be a cable running to the wireless router. Check the integrity of all wiring - are there any strong kinks anywhere, are all plugs firmly inserted into the sockets and are they inserted where they really need to be. Provided that no problem is found here, we move on to the next step.

Connecting via local network Windows 7 without access to the Internet

It happens that the installed router simply freezes. In this case it helps. To do this, just turn off its power and connect it again after a few seconds. It won't hurt to restart your computer at the same time. If your router freezes like this with annoying regularity, consider buying a new device. You should also try connecting the Internet cable directly to your PC or laptop. If there is no result, first we’ll deal with the computer.

Checking your computer settings

It is possible that the problem arose “out of the blue”, then problems with the settings on the computer should not arise; much more often the problem arises during the initial configuration or making any changes to an already working network. First of all, you need to check that the IP address of your computer is correct by pressing Win+R on your keyboard at the same time. The Run window will open. In its line, enter ncpa.cpl and click OK. The network connections window will appear. It may happen that there are several of them, but the required one will not be crossed out with a red cross and its name is similar to “Local Area Connection” or “Wireless Connection” (in the case of using Wi-Fi). Right-click on the desired connection and go to properties, where the list will contain lines with IPv4 and IPv6 entries. Check the box next to IPv6, and double-click on IPv4. Check the boxes to automatically receive settings and save the changes. If access to the Internet does not appear, move on.

Setting up a local network connection in Windows 7

Finding out the router address

Perhaps you didn’t have to do anything in the previous window, the settings for obtaining IPv4 and IPv6 protocol addresses are automatic and everything was initially as it should be. Then you just need to configure the router, for which you need to know its address. Right-click on the connection again and select “Status” and then click “Details”. There will be several lines in the window that appears; we are interested in “IPv4 Address”. If you see an entry like 192.168.x.x, remember or write down what is indicated opposite “IPv4 DHCP server” - this will be its address. It may be that the computer is not able to receive the settings automatically, then the entry will look like 169.254.x.x. You can find out the router’s IP from its documentation, or it is indicated on the device’s case, and most often it is 192.168.0.1 or 192.168.1.1. Open your browser and enter the established IP in the address bar, and if it is correct, you will be prompted to enter your login and password.

Internet Protocol Version 4 (TCP/IPv4) Properties

Setting up an internal network on the router

After correctly entering your credentials, you will be taken to the router control panel, and further actions depend on the device model and its firmware. You need to find a DHCP server control, which is responsible for automatically obtaining IP addresses and other parameters necessary for the network to function properly. Look for blocks whose names include DHCP settings, DHCP server, or similar. The block will contain a switch with the values ​​Enable or Disable. Most often, these settings are located in the LAN section. Enable the DHCP server, save the changes and reboot the router. Once this is done, an Internet connection will appear on your computer.

Check your connection settings to your provider

You should not jump to hasty conclusions if the previous steps did not help set up the connection. Since the network is still not working normally, we check the connection with the provider, for which in the router control panel, go to the appropriate section. Almost all manufacturers call these options WAN or Internet. There are quite a lot of settings options in this section. Which ones are intended for you, you can find out from the contract or from the technical support of your service provider.

Reinstalling network card drivers and checking the firewall

It makes sense to do this when you are sure that all previous settings are correct, the connection with the provider is established, but the network cannot be configured normally. The best option would be to download the most recent version of the driver from the manufacturer's website, which, it seems, will require going to a friend or neighbor. If this is not possible, the driver included on the installation disk will do. After reinstalling, be sure to restart your computer. Here it is also necessary to note driver failures that occur due to installed software that makes changes to the operation of network protocols on the computer. The most common representatives are antiviruses and firewalls. Make sure that such programs are not installed, and if they are, disable or remove them during the test, as they may block the connection.

Replacing the MAC address of a network card

Problems with MAC addresses sometimes arise in cases where the network is very large, but it is still worth eliminating it. On your computer, go to the device manager, press the Win+R keys, enter devmgmt.msc and click OK. The device manager will launch, where you need to find the “Network adapters” section, expand it and select the network card with which the PC is connected. After double-clicking on it, in a new window, on the “Advanced” tab, select the Network address option and enter any twelve digits in the empty field on the right. After that, reboot and look at the result.

Clear DNS cache and reset TCP/IP settings

The following steps will reset all network settings for IPv6 and v4, so you must follow them. If you are ready for this, and you have information about all the settings (written down somewhere, for example), find the command line in the Start menu and run it with administrator rights. Enter the following commands in the window that appears, confirming your entry by pressing Enter. After running each command, restart your computer and check the result.

1. ipconfig /flushdns
2. netsh winsock reset
3. netsh int ip reset c:\resetlog.txt - this command will completely reset all connections and you will have to configure them again!

Clearing the DNS cache using the command line

You have a direct connection to your provider

The option when your computer is connected directly to the provider, bypassing the router, is now becoming less and less common, as the number of network devices is steadily growing. But what to do if you have just such a connection? Eliminate possible problems with drivers as indicated above and check that the connection settings are correct. Regarding the settings, the best option would be to contact technical support, since there are a lot of variations.

Nothing helped at all

Maybe you're lucky and your ISP provides access using the new IPv6 protocol, the configuration of which requires knowledge of some subtleties. It should be noted that the expansion of the use of IPv6 is inevitable, since the address space of the previous version of the protocol, IPv4, has come to an end, and the global network is growing every day. Since your efforts have been wasted, and your network still hasn’t started working, then there is only one piece of advice - call a specialist. It is quite possible that the problem that has arisen is non-standard or that equipment replacement/repair is required to solve it.

There is Internet access, but the error remains

This situation may well exist. The reasons may be different - most often when connecting through a proxy server. However, there is only one solution. Press Win+R, enter gpedit.msc - this will take you to the local group policy editor. In the menu on the left, go through the following items: “Local Computer” Policy - Computer Configuration - Administrative Templates - System - Internet Communication Management - Internet Communication Settings. Now, on the right side of the window, find and enable “Disable active probing for network connection status indicator.” In Windows 10, this setting is called "Turn off active network connection health checks." Please note that now, even if there is truly no connection, the message will not appear.

Conclusion

This article collects the most common problems associated with the “Network without Internet access” error and suggests ways to solve it. We hope that the material was interesting to you and helped you overcome the difficulties you encountered.

USB modems from cellular operators have long ceased to be something out of the ordinary and have gained unprecedented popularity among Internet surfers due to their ease of setup and use. MTS provides users with a fairly wide range of options when purchasing such a device and concluding a contract for payment for services. However, quite often you can encounter situations when the MTS modem does not connect to the Internet, despite the fact that most of the settings are fully automated, and the user’s special participation in all processes is minimized. We’ll look into what you can do if such problems are noticed.

How to connect to the Internet via an MTS USB modem?

As a rule, the user does not need to do anything special when connecting a modem to a USB port.

The modem is detected in the system as a removable disk, after which, if autorun is enabled, the installation of drivers and Connect Manager software starts. If autostart does not work, you need to go to the root of the removable disk and run the Autorun.exe file yourself. Next, you need to follow the instructions of the “Installation Wizard”, and upon completion of the process, a shortcut will appear on the “Desktop” for making an immediate connection.

How to connect to the Internet via an MTS modem? Double-click to call the connection console, after making sure that the SIM card is inserted and there is money on the balance. After registering the device on the Internet, press the connect button and wait until the connection is established. Please note that at first a message may appear in the status bar stating that the modem is not connected, but this is a temporary phenomenon. Wait a little.

After some time, the connection should be activated. As you can see, you don’t need to configure anything, since the operator has already made sure that the drivers and necessary parameters are installed automatically.

Main types of errors

But let's look at situations when the MTS modem does not connect to the Internet, despite the fact that you have completed all the steps according to the instructions. Indeed, failures in the operation of such devices are observed quite often.

If connection is impossible for some reason, you will have to take several steps to eliminate them. The most common is error 619, indicating that there are not enough funds in your account.

However, you can encounter other failures, among which the most typical are the following:

• modem failure;
• missing or damaged original device drivers;
• disabled USB ports;
• conflicts with other equipment;
• overlapping frequency ranges when distributing a signal wirelessly using a router;
• blocking the connection by third-party applications;
• failures in the operating system,
• problems on the operator's side.

The MTS modem connects, but the Internet does not work. What to do first?

So, let's move on to troubleshooting possible problems. The first step is to check the operation of the device on another computer or laptop. If no failures are detected when connecting the modem, you should look for the cause in your own computer terminal. The easiest way out of this situation is to temporarily disable the built-in Windows firewall and antivirus (especially if it is some free software product like Avast). If this does not help, and the MTS modem does not connect to the Internet, move on.

What to do if the modem is not detected in the system?

Let’s assume that the installer seems to have performed all the steps automatically, but the modem is still not among the devices in the “Device Manager”. To begin, expand the entire list by using the show hidden devices item. If there is a modem there and it's marked with a yellow triangle, or you see an unknown device, you'll need to update or reinstall the drivers, telling the system to either search for software on your local computer or set the source to a removable device. If this does not help, you need to go to the operator’s official website from another terminal, download the latest drivers for your modem model, and then install it yourself.

Sometimes the problem that the MTS modem does not connect to the Internet or is missing from the installed devices is solved by reconnecting to another USB port.

At the same time, in the “Device Manager” you need to check the status of the drivers of USB controllers and hosts (all without exception), and, if necessary, perform an update or rollback, depending on the current situation.

The modem is detected, but does not work: device diagnostics

In principle, if the modem does not connect to the Internet, but no problems have been identified with it at the operating system level, you can directly use the diagnostic tool provided for this in Windows. In the equipment properties, you need to set modem polling. After this, either a message will appear indicating that the process has started. If this does not happen, the device simply does not work. As an additional measure, you can run “Connect Manager” and see if the modem is detected in this program. If it is not there, run “ipconfig /all” (without quotes) on the command line, and once you know your address, contact technical support.

Configuring router settings

Finally, let's see what can be done to correct the situation if the MTS modem does not connect to the Internet through a router, which can be used to distribute a wireless signal.

First, in the IPv4 protocol properties for the created connection, make sure that all types of addresses are set to receive them automatically (this is a prerequisite). Secondly, go to the router’s web interface, go to additional settings and check the options in the USB application settings. They should be like this:

• APN: internet.mts.ru;
• Access number: *99# or *99***1#;
• Username: mts Password: mts.

In addition, the MTS operator must be selected in the list of mobile Internet providers, and Russia must be indicated as the region. As is already clear, if something does not correspond to the described parameters, you need to change the options, save the settings and perform a complete reboot of the router.

Note: when connecting the modem directly to the router via a USB port, it is advisable to check the operation of the port itself. If it is broken, damaged or inoperative, you can’t even dream about the operation of the modem-router combination.

A device such as a modem from MTS is made for quick access to the Internet using a computer or laptop that has a regular USB output. This device is very convenient, because it can be used anywhere, as long as there is a signal. But often modems may stop working, and there may be several reasons for this, so you should deal with each problem separately.

Features of faults

To determine why the modem is not working, you should first check the balance in your SIM card account. In some cases, even a small amount of funds cannot be used to access the network. You can view all the recommendations and requirements for a SIM card account on the company’s website. There may be restrictions that are written in fine print or hidden from the client.

Additionally, you need to check the functionality of the equipment itself by using it on another PC. If it works, then the problem lies in the personal computer or its software. If the modem does not work on different devices, then the problem may be in it. For this, there are also recommendations and typical problems that are presented on the site.

If the reason is not identified, then you should check the compatibility of the modem and the computer OS. You can launch MTS Connect and wait until the modem is identified in the system. At the same time, you can turn on the device manager and check whether there is MTS equipment in it.

New drivers may be required for operation. Therefore, they should be reinstalled, and you can download them on the MTS website or other resources.

Each modem is equipped with special indicators that indicate the status of the device. The indicator will start to light when power is supplied to it, in other words, immediately after it is plugged into the USB port. Different indicator colors may represent different functions.

Now we need to deal with possible problems in more detail.

The indicator is on, but the modem does not work

When the indicator lights up, it means you need to go to the task manager and find the modem definition on the computer. This can be done by going to the list of devices, but you can simply check its operation. To enter the device manager, you need to go to the control menu and select the “System” section. Then go to the equipment section and click on the dispatcher itself.

For another method, you can use a couple of buttons: Windows + R, after pressing them a menu will appear on the screen where you need to enter devmgmt.msc and click on the OK button.

Modem is not in the list

When the equipment is not located by the computer, this means:

1. The modem is not plugged into the USB port.
2. No required drivers.
3. The modem is broken.
4. The USB port is not working.
5. Drivers crash.

If the modem is not in the list, and there are no unknown devices, then you will need to check whether it is correctly included in the port, or even better, move it to a different port. When the indicator starts to glow, then the modem has not burned out and is working. The instructions for the device contain designations for indicators; each color is responsible for different functions. If the indicator shows that the device has connected to the MTS network, then the problem is in the computer software, but a modem driver failure cannot be ruled out.

If the indicator indicates that the device is working, you will need to reinstall the drivers for the modem. If the drivers are installed, but the modem is not detected, then the drivers may not be suitable for another version of Windows.

When the device was working normally, but stopped after a while, and is detected in the device manager, you should simply remove it and insert it into the port. Then restart the PC.

There is a modem in the list, but it does not function

When the MTS modem does not work, but it is in the list of devices, then diagnostics are carried out. The modem must be selected on the PC and its properties displayed. This can be done by right-clicking. Next, the diagnostic window opens and the modem polling key is pressed. As a result, testing will begin and a certain text will appear. If it is not there, then the device does not function as it should. Perhaps it has incorrect drivers or the modem cannot work with other devices. In the menu that is available, you can make another diagnosis if you press the button for additional communication parameters.

It is possible that the initialization string was not written correctly, as a result of which the device is not able to operate normally. It should ideally be empty if the connection is made via MTS Connect.

Diagnostics in the list of devices

After diagnostics, the modem gives the correct answer, which means you can move on to another action, namely, check for a network connection. You should go to the control panel and go to the network connection. The action can be simplified if you press Windows + R and enter ncpa.cpl.

Next you need to find the connection and select it and go to properties. In the open menu, go to the “General” section and check the connection to the equipment. Then open the “Network” section and the TCP/IP protocol should be empty. When this is the case, you should try connecting to the Internet. After this, certain outcome options may arise:

1. It is impossible to connect to the Internet, and an error code and text for it appear on the monitor.
2. There is access to the network, but in fact it is not possible to access the Internet.

If access is denied, then it is recommended to write down the error code and call the operator to clarify the data. The most common code is 619. This code means that there is not enough money on your balance to surf. It's not often that code can indicate that there is a network failure or that technical work is underway.

If there is a connection, but you cannot access the Internet, then the parameters are checked. To do this, call up the menu by pressing Windows + R and enter cmd. Next, a menu will appear in which the ipconfig/all request is entered and the input is pressed. Next, having received the data, you need to call the MTS operator and find out the reasons or get help. Problems include:

1. The operator has problems.
2. A certain application or program is blocking traffic.
3. Computer OS failures.

Don’t be upset if there are different types of problems with network access; often these are operator failures and not a hardware problem. As a rule, failures at the MTS provider most often occur in the evening and during the day, when the network is heavily overloaded. Sometimes the connection speed may simply deteriorate.

The Internet is an integral part of our lives - it is an excellent assistant in work, an indispensable tool in learning, moreover, it is a means of communication and relaxation. Users everywhere are facing connectivity issues. Let's look at the most common error in this article - IPv4 without Internet access and how to fix it? If Windows gives you this alert, then you should use the method of elimination to go through all the options in order to find out what caused the occurrence.

Ipv4 is Internet Protocol, I think it doesn’t need translation, and the protocol version is the fourth. You probably noticed that the IPv6 protocol is present in the settings - this is also an Internet protocol, but already in its sixth version, only a few providers use it. The most common and basic today is IPv4. The main task of the IPv4 protocol is to ensure the functioning of the computer and networks according to established rules for the exchange of data packets. Thus, interaction occurs between the communication node and the IP address of the machine; IPv4 is a low-level protocol.

If the terminology causes you difficulties, then we additionally recommend that you read our other article,

In order to correct the access problem accurately and as quickly as possible, we will consider the cause and method of eliminating it.

Reboot: rebooting will help fix the error

It’s not for nothing that a well-known proverb in IT specialist circles has taken a new form and sounds like: “Seven troubles – one reset.” In our case, reset is a last resort to fix the error. Terms:

• reset – or rollback to the last successful version;
• reboot – reboot, in other words, complete unloading and loading of the operating system;
• restart – restart.

Let's start fixing the situation.

1. Restart your computer (don't turn it off and on!). Sometimes this is a fairly effective method to fix the problem.
2. 99% of users use routers and routers, since there is more than one device with Internet access in the house - reboot the router / router.
3. Try pausing or completely disabling the antivirus; for various reasons, blocking occurs because of it. If everything works, reinstall the antivirus and you may need to update the program module.
4. Analyze what changes were made to the system before the IPv4 error without network access occurred. Try rolling back the installation/configuration of a program/utility, etc., if this corrects the situation, then the reason is precisely in the changes made earlier.

Small experiments...

Did the above steps not help fix it? Let's go further, we need to exclude the possibility of a problem on the provider's side, namely, check whether the Internet works on other devices.

1. Check the other device for network access. If everything works on that device and there is no IPv4 error without network access, then the problem is in the computer. This could be either a software error or a physical malfunction. We will consider a software error in more detail below, but a physical error can be from a disconnected network cable (patchcourt) to a broken network card.
2. If the machine is connected directly without a router, and an IPv4 error occurs without access to the network, try connecting another computer/laptop instead. Again, depending on whether it works or not, we check the physical condition and then move on to software solutions.
3. If the network does not work on any of the devices connected by any of the methods, call your provider’s technical support for clarification and do not forget to voice that Windows displays the message “IPv4 without Internet access.” They should help fix it.
4. This will probably sound banal and even a little funny, but if our little brothers live at home, check the integrity of the cables, damage is possible, which is what caused the above error - IPv4 without access to the network.

Look to the root...

Having ruled out a number of simple reasons to fix the problem, let's move on to the most important ones. The World Wide Web does not work, and the operating system displays an error: IPv4 without Internet access. So, let's start in order.

Internet settings: ISP and router

Of course, the easiest thing is to call your provider and clarify everything with him, first telling him about the error - IPv4 without Internet access. Perhaps a specialist will advise how to fix it. First, you need to look into the settings of your router and check whether the data has been entered correctly. Let's see what an IPv4 error looks like without Internet access. Regardless of whether the connection is made via Wi-Fi or using a network cable, a yellow exclamation mark will appear.


I would like to make a reservation that the fix for the problem with the IPv4 name without network access is the same for both different connections and versions of Windows, starting from 7 and up to 10. To fix it, you must first find out the cause of the IPv4 error without Internet access.
Go to the “Network and Sharing Center” - using any of 2 methods:

1 way

 right-click (hereinafter referred to as RMB) on the connection sign with a yellow exclamation mark → select “Network and Sharing Center” → note that in the “Access Type” it is indicated “Without Internet access” → select “Change adapter settings” → find your connection;

2 way

Having reached the desired directory:

• “Windows Network Diagnostics” will launch - wait for it to complete and, as a result, problems will be detected, as well as advice on how to fix them.
  
  
• diagnostics determined that this is the main reason for the IPv4 error without Internet access;
  
  
• to fix it, go to the “Status - Ethernet” or “Status - Wireless Network Connection” window - using the method indicated above;
• select “Properties” → select “Internet Protocol Version 4 (TCP/IPv4)” → “Properties”.
  
  
  In the window that opens, you must specify the type of IP address and DNS. We will describe all possible options on how to fix the IPv4 problem without Internet access.
  
  

Static IP and DNS

Is your home network configured in such a way that each device has its own and access is carried out using DNS? To accurately specify the settings and fix the IPv4 error without access to the Internet, go to your router, we show the example of the Asus router.

• the address of the settings page is available at “192.168.1.1” – enter without quotes in the address bar of the browser → → authentication is required, usually the login and password “Admin”, login can also be done without specifying a password;
  
  
• go to the “LAN” section → “LAN IP address” → the specified IP address is the main gateway;
  
  
• Next, go to the “DHCP server” section - the starting and ending pool of addresses is indicated here, as well as a list of those already assigned by MAC address of the device. The MAC address is the unique serial number of the network card. Find the device you need and remember/write it down.
  Dynamic IP address

  It happens that everything is configured correctly, but a DNS server error occurs and the system displays a message - IPv4 without network access. This is due to an overload or error in the operation of the DNS servers on the provider’s side. Moreover, the router shows that the Internet reaches you. In this case, to correct the situation, alternative DNS from Google, which are public, come to the rescue. So:

  
  

  With this simple method, you can fix the IPv4 connection error that occurs.

  Stable connection!
