Modem without network access. The Internet does not work on the computer via cable or through a router

How to install a 3G USB modem in Windows is written in another article. Methods will be discussed here problem solving problems that arise when using these modems. And in relation to Windows OS.

If you have problems - the modem does not install, does not work or does not connect, then you need to start diagnosing with a visual check of the modem.

Each USB modem has an indicator that shows the current status of the modem. This indicator lights up when power is supplied to the modem, that is, as soon as you plug it into the USB connector of the computer.

• blue flashing or constant - connected via WCDMA (3G) protocol.
• green flashing or constant - connected via LTE (4G).

If the indicator on your modem does not light up at all, then it is possible:

• The modem is "dead".
• The computer's USB connector does not work or does not work correctly (for example, weak power to the connector).

Try plugging the modem into a different connector and into a different computer.

If the modem indicator is on

To further check, you need to open the device manager and see if the modem is in the list of devices, and also check how it works. Device Manager can be opened via Control Panel - System:

But there is a shorter way. You need to press the Windows + R buttons on your keyboard and enter “devmgmt.msc” in the window that opens and click “OK”:

In Device Manager, you need to find and expand the “Modems” item:

This picture shows a Huawei modem; you may have a modem from another company, but this does not change the essence of the matter.

The modem is not in the list of devices

If the modem is not in the list of devices, it means:

• it is not plugged into the USB connector;
• modem drivers are not installed;
• the modem died;
• USB connector does not work;
• USB driver failure.

Note. If the modem is in the list no devices, then look to see if there are unknown devices in the list - they are marked with a question mark. An identified but not connected device can also be highlighted with a sign (yellow triangle). For example, a modem may be in the “USB bus controllers” branch as “composite USB device".

If there is neither a modem nor unknown devices, or disconnected devices, then you need to check how it is connected to the USB connector, or better yet, pull it out and plug it in again, maybe into another USB connector. Look at the modem indicator; if the modem indicator is blinking, then the modem is probably alive and working normally. Look in the passport of your modem to see how the indicator should light if the modem is connected to the network mobile operator. The fact is that the modem connects to cellular network operator after power is applied to it. If the indicator shows that the modem has connected to the operator’s network, then the problem is software and may be related to drivers or Windows.

For example indication Huawei modems is this:

• red flashing - either did not connect to the operator’s network, or connected via the GSM (2G) protocol;
• blue flashing - connected via WCDMA (3G) protocol.

If the indicator shows that the modem is working, then install or reinstall the modem driver.

If the driver is installed, but the modem is not detected or is detected, but is marked with a triangle (disabled), then check - maybe you have a 64-bit version of Windows installed, but the driver is installed for the 32-bit version.

If the modem worked, but then stopped, for example, when exiting Hibernate mode and it is visible in the list of devices as a “composite USB device,” then you can try unplugging it and plugging it in again, and if that doesn’t help, then restart Windows.

The modem is in the list of devices

If the modem is in the list of devices, then you can proceed to the next diagnostic step. Select the modem and right-click, and then select "Properties" from the menu. In the "Modem Properties" window, open the "Diagnostics" tab:

and click the "Poll the modem" button. As a result, the following text should appear:

If there is no such text, then the modem is not working properly. It may be disabled by the system due to incorrect drivers or a conflict with another device. Also, in this window, check the "Advanced communication parameters" tab:

Perhaps an incorrect initialization line is entered there, which does not allow the modem to work correctly. This line should be empty if you are connecting through your provider's program (for example MTS Connect), and if you connect directly, via Windows tools, it should contain the correct line for your ISP. The figure shows the correct line for the MTS provider.

For Beeline it will be AT+CGDCONT=1,"IP","internet.beeline.ru".

For Megafon AT+CGDCONT=1,"IP","internet".

The modem is diagnosed in the list of devices

If, when polling the modem, it answers correctly, then you can proceed to the next diagnostic step. You need to check your network connection settings. To do this, you need to open the Control Panel and find and open “Network Connections” in it. Or easier - Windows + R and in the window that opens, enter " ncpa.cpl" and click "OK". In both cases the folder will be opened network connections.

Note. For Windows Vista/ 7 the path to the folder is “Network and Sharing Center” and there is a link “Adapter Properties”.

Find the connection you need, select it and right-click, and then select “Properties” from the menu. In the "Properties" window - on the "General" tab, check that the connection is connected to your modem:

Select it and click the "Properties" button. Nothing should be written there:

If everything is so then close everything open windows and try to connect.

• Internet connection is not established. In this case, an error is displayed with text and number.
• The Internet connection is established, but nothing really works. The browser does not open pages mail program doesn't receive mail.

If the Internet connection is not established, then write down the error text and error number, and then call your provider by phone technical support(or by calling the call center).

• For MTS this is number 0890 or 8-800-333-0890.
• For Beeline 0611 and 8-800-700-8000.
• For Megafon 8-800-333-05-00.

For example, the most common error on USB modems is No. 619. Typically, such an error means that there are not enough funds in your account and access to the Internet is blocked for you. Less commonly, this error means that your provider's channels have technical problems, they are usually temporary.

If the connection is established but no Internet programs work, then in this case you need to look at the Internet connection parameters. You need to press the Windows + R buttons on your keyboard and enter “cmd” in the window that opens:

In the window that opens, enter the command "ipconfig /all":

and press Enter. In the information that the command will produce, you need to find a block related to the “PPP” adapter:

If there are no such entries, this means that your modem has not received network settings from the provider, however, receiving such settings does not guarantee the correct operation of the connection. Having this data, call your provider's technical support number and find out what the problem might be.

Or you can continue self-diagnosis. In the same window, enter the command " ping xxx.xxx.xxx.xxx"where instead of X's put the address of your DNS server:

The correct result should be like the picture above. But if the result is like this:

This means that the connection is not established correctly - packets from your computer do not reach the DNS server. In this case, try to ping to the WINS servers if they are specified or to the “default gateway” if an address different from the address of your computer is specified there.

If errors are detected in the passage of network packets, this happens because:

• There are problems in the provider’s network, so first call your provider’s technical support.
• You have some kind of program installed that blocks some network traffic using the TCP/IP, UDP, ICMP protocol, for example a firewall or antivirus. Check all running programs.
• Stack settings are broken network protocols Windows. Network protocol stack settings can be reset to default with the command " netsh int ip reset c:\resetlog.txt"or the WinsockFix program.

If ping to the DNS servers goes well, then you can check the connection by ping the site name (for example yandex.ru):

If sites are not pinged by name, but are pinged by IP address, this could mean:

• a problem with DNS servers your provider;
• Some program on your computer is blocking UDP port 53.

You can exclude your provider's DNS servers by specifying alternative DNS servers. This is done in the connection properties and then in the properties of the "TCP/IP" protocol (above in this article it is written about the "Connection Properties" applet).

If sites do not ping by name even with other DNS servers, then you need to understand the programs that are running on your computer.

The situation when the modem establishes a connection, but the Internet does not work (websites do not open, Skype does not work, etc.) is the most “murky” - it is difficult to determine the source of the problem. It could be:

• There is a network problem with the provider.
• Some program blocks part of the traffic or all traffic on network protocols.
• Network protocol stack failure operating system.

In this case, you need to move forward step by step, eliminating one possibility after another. For example, try connecting through a different operator. Open the list of running processes and “kill” all suspicious ones. And so on.

Connection problems or problems with the operation of the 3G Internet connection are not always caused by problems on the user’s computer. Often these are problems with the telecom operator. For example, at MTS, it happens during the day and evening poor quality connection (overload on the equipment), which is expressed in the following symptoms - the connection is established, but either extremely low speed, or there is no real packet movement at all. Disconnecting and reconnecting, sometimes several reconnections in a row, can help. So when problems arise, do not rush to look for the problem yourself first.

Ivan Sukhov, 2011 .

Owners of devices running a family of operating systems Windows systems, with varying frequency encounter problems when making an automatic network connection, regardless of the use of wired technology or Wi-Fi router. The first sign of a problem is the exclamation point icon in a triangle displayed on the network connection icon. If you go to the Network Connections Administration Center, you will see “unidentified network without Internet access” in place of the name of your access point.

Let's look at the reasons for the error. It occurs when a physical connection has taken place, but the settings of the network equipment on your laptop or computer do not match those installed on the router or network equipment provider.

The reason for this may be:

• an operating system update that resulted in changes in network equipment settings;
• installation new version drivers for network or wireless equipment that caused an error in the settings;
• malfunction on the provider side;
• Problems with the router during a wireless connection.

Options for solving problems as their complexity increases

Often to fix a problem with unidentified networks system administrators It is recommended to go straight to manual setting communication protocols. We believe that this approach is not entirely correct, so we suggest you follow the algorithm we have developed for localizing a problem with a network or Internet:

If after all the steps taken the problem is not resolved, contact your provider again to call a technician to your home.

FAQ

Which connection causes the error without network access to occur more often?

Because there are many causes of network connection errors, it is difficult to pinpoint which type of connection is statistically more common. If you are using cable connection, go to wireless network can be considered as an alternative method to solve this problem.

Whether there is a universal method counteract this problem?

Unfortunately, it doesn't exist unless you seriously consider moving to other operating systems. Part Windows errors confidently migrates to every new OS and is considered by some users as business card Microsoft Corporation products.

The first setup of an MTS 4g modem is both simple and skill-requiring. This unit is designed so that you can access the network where you need it and when there is no access to wired Internet or Wi-Fi is not available. MTS 4 g network coverage covers a large area, so there should be no problems with communication. It is a small unit that is inserted into a USB connector like a flash card. Do you agree that it is very convenient to have it at hand? The device does not take up much space and can easily fit into a laptop bag or just a pocket.

To get started, just perform a small setup that can activate the MTS 4g 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; you only need to agree to the actions being performed and indicate 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 also read about.

How to connect an MTS 4g modem to a computer

Initially, you should, as you already guessed, insert the SIM card into a special slot. The device will operate in LTE networks only with the SIM card that comes with it. If you install another SIM card, it will work on the 3g network and the speed, accordingly, will be lower than declared. Here you can find out, maybe 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 your computer or laptop. The operating system will automatically detect and recognize new hardware, and then activate the installation wizard itself. If this does not happen, then you need to go to the “Start” menu, then go to the “Computer” section. USB tethering will appear as removable drive, since by its configuration it has a card slot Micro memory SD. Installing a memory card allows us to use it as a removable drive.

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

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

• Launch the program shortcut "Connect Manager", which will appear on the desktop after installation.
• When the modem registers 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, just wait for the connection. Immediately after establishing a connection to the Internet, the message “MTS connection is connected to the network” will appear in the device selection menu.
• In the “Connect” section, click the “Disconnect” button to pause your 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 a 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 connected to the World Wide Web using a flagship with the function wifi router. You can connect such a 4g MTS modem to a power adapter or PC and use it to launch no more than 10 devices at the same time.

The installation process will depend on the computer's operating system. Let's look at the installation for Windows XP as an example:

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

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

• Check your access point settings- the checkbox is not used by default and must be cleared;
• Make sure that other devices do not work to distribute the signal, this may lead to a malfunction of all modules.
• If you still can’t access the Internet, try restarting your computer.

You can look at it in a separate article.

This instruction contains step-by-step information on what to do if the Internet does not work on a computer with Windows 10, 8 and Windows 7 in various scenarios: the Internet disappeared and stopped connecting for no reason via the provider’s cable or via a router, the Internet only stopped working in the browser or certain programs, works on the old one, but does not work on the new computer and in other situations.

Note: In my experience, about 5 percent of the time (and that's not a small number) the reason the Internet suddenly stops working is with the message "Not connected. No connections available" in the notification area and " Network cable not connected" in the list of connections indicates that the LAN cable is really not connected: check and reconnect (even if visually it seems that there are no problems) the cable as on the connector side network card computer, and from the LAN connector on the router, if the connection is made through it.

If the first option does not suit your situation, then I recommend following these steps to check your Internet connection:

Let's stop at point 6 - connection via local network shows that everything is fine (on, there is a network name), but there is no Internet (this may be accompanied by the message “No access to the Internet” and a yellow exclamation mark next to the connection icon in the notification area).

LAN connection is active, but there is no Internet (no Internet access)

In a situation where the cable connection works, but there is no Internet, there are several common causes of the problem:

1. If the connection is made through a router: there is something wrong with the cable in the WAN (Internet) port on the router. Check all cable connections.
2. Also, for the situation with the router: the Internet connection settings on the router have gone wrong, check (see). Even if the settings are correct, check the connection status in the router’s web interface (if it’s not active, then for some reason the connection cannot be established, perhaps the 3rd point is to blame).
3. Temporary lack of Internet access on the part of the provider - this does not happen often, but it does happen. In this case, the Internet will not be available on other devices via the same network (check if possible), the problem is usually fixed within a day.
4. Problems with network connection settings (DNS access, proxy server settings, TCP/IP settings). Solutions for this case are described in the article mentioned above and in a separate material.

For the 4th point of those actions that you can try first:

If these two methods do not help, try more sophisticated methods of solving the problem from the separate instructions given above in paragraph 4.

Note: if you have just installed a router, connected it to your computer with a cable, and there is no Internet on the computer, then most likely you simply have not configured your router correctly yet. Once this is done, the Internet should appear.

Computer network card drivers and disabling LAN in BIOS

If the problem with the Internet appeared after Windows reinstallation 10, 8 or Windows 7, as well as in cases where there is no local network connection in the list of network connections, the problem is most likely caused by the fact that the necessary network card drivers are not installed. Less often - because Ethernet adapter disabled in the BIOS (UEFI) of the computer.

In this case, you should follow these steps:

Perhaps in this context it will be useful: (if there are unknown devices in the list in the task manager).

Network card parameters in BIOS (UEFI)

Sometimes it may turn out that network adapter disabled in BIOS. In this case, you definitely won’t see network cards in the device manager, and local network connections in the list of connections.

The parameters of the computer's built-in network card can be located in different sections of the BIOS; the task is to find and enable it (set to Enabled). This might help: (also relevant for other systems).

Typical BIOS sections where the required item may be located:

• Advanced - Hardware
• Integrated Peripherals
• On-board device configuration

If the adapter is disabled in one of these or similar sections of the LAN (may be called Ethernet, NIC), try turning it on, saving the settings and restarting the computer.

Additional Information

If by now you have been able to figure out why the Internet is not working, as well as making it work, the following information may be useful:

• In Windows, Control Panel - Troubleshooting has a tool to automatically fix Internet connection problems. If it does not fix the situation, but provides a description of the problem, try searching the Internet for the text of the problem. One of the common cases: .
• If you have Windows 10, look at the following two materials, they may work: , .
• If you have new computer or motherboard, and the provider restricts access to the Internet by MAC address, then you should provide him with a new MAC address.

I hope that one of the options for solving the problem with the Internet on a computer via cable was suitable for your case. If not, describe the situation in the comments, I will try to help.

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). Usually, in the description of your tariff plan maximum speed is indicated, which means the speed available in your area may be lower.

It's also worth noting that even if you have 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. At good conditions, the latency of a mobile broadband Internet signal can be as low as 50 milliseconds, making even high-speed shooting games possible, but weak signal it can be more than 500 milliseconds when you can only play strategy games like World of Warcraft.
