The connection to the Windows 7 modem constantly drops. The modem turns off randomly: causes and fixing the problem

“The Internet periodically disappears”, “Yesterday I used the Internet, but today the connection is lost”, “The program does not want to connect to the Internet” - these and many other similar complaints can be heard from users who, for one reason or another, are faced with the problem of lack of connection with the global network. It’s not pleasant to receive such problems if your activity is related to daily visits to the network, regardless of whether you use it for communication, work or for entertainment purposes. There can be many reasons for the lack of Internet connection, and I will try to give general tips to eliminate them, but first you need to figure out why your Internet still disappears.

I divided the whole range of reasons why you may not have Internet into two groups: external and internal. TO external reasons I include those that lie outside yours computer system and which are very difficult to solve on your own. Usually, to restore breaks due to external reasons, you have to contact various service organizations. Internal ones are quite amenable to solving on your own, since they are within the coverage area of ​​your own computer system.

External reasons for Internet shutdown

1. Problems with the provider

I will probably put this reason for the lack of communication first among others. The provider is an intermediate link between you and the global network. Everything you request or receive from the network will necessarily go through the provider. It is this organization that will be responsible for connecting to the Internet in front of you and in most cases, in case of unclear connection failures, you need to contact the technical service of your provider. Of course, not all problems of lack of Internet can be solved through the service of technicians, since the culprit of connection breaks may also be your system with a set of programs installed on it, as well as their settings. But believe me, in most cases, the issue of restoring communication via the Internet channel lies within the competence of your provider. The reason for this may be damaged wires, faulty equipment, or even unscheduled work that they forgot to warn you about.

It would also be a good idea to check the balance of your Internet account, to which each provider must provide access. Depending on the chosen tariff and internal rules for providing access to the Internet, each organization can set its own limits for your balance, within which you can continue to use the Internet channel. As soon as the balance goes out of these limits (for example, it becomes less than 0 rubles), access to the Internet is automatically blocked by the provider’s system. It comes to funny cases. A similar thing happened to me when I used Internet access through the MTS provider. One day my account balance was about 5-6 rubles, after which the Internet stopped connecting at all. At the same time, in technical service argued that no sanctions should follow from their system for any positive balance. However, as soon as I topped up my account with another 100 rubles, the connections immediately returned to normal.

2. Lost communication channels

Also, a frequent reason for a suddenly lost connection may be hidden in a violation of the integrity of physical channels located within the building/apartment/room where the Internet channel is installed. To accurately diagnose such reasons, you need to know the type and features of the physical communication channel through which the Internet reaches you within your premises.

If it is a cable type channel (for example, telephone, television coaxial or twisted pair), be sure to check the integrity of the corresponding wires that are laid in your apartment. However, it must be added that in some cases, check the integrity of the cable without special equipment is not possible, but there are a number of ways to diagnose a cable connection without professional tools.

A telephone connection, often used with ADSL or Dial-Up Internet connections, can be diagnosed using a regular telephone, which is connected instead of a modem. The absence of beeps in the handset will clearly indicate a damaged line.

Twisted pair, which is usually connected directly to your computer's network card, is even easier to diagnose. In most cases, all you need to do is make sure that the RJ-45 port indicator on the network card where the twisted pair cable is connected is green.

In most cases, the absence of light from the indicators indicates a malfunction in the cable itself or its connecting parts. However, if you do not have the proper experience and knowledge in troubleshooting the malfunctions described above, it is better to contact qualified technicians, who can be invited through the service provider or check their telephone contacts.

Internal reasons for Internet shutdown

3. Faulty equipment

Quite an insidious type of problem. More than once I have come across cases when externally working equipment cannot fully connect to the Internet or operates with periodic failures due to internal technical problems, which are quite difficult to diagnose without special knowledge. In this paragraph, I am referring to modems and network cards, which are intermediaries between your system and the provider’s equipment and which you use to connect to the Internet.

You can make sure that the modem or network card is fully operational through the system equipment manager. To do this, right-click on the “ My computer” go to item “ Properties" If you have Windows 7, then find the link to the “” window on the left; if you are the owner of Windows XP, then first go to the “” tab Equipment”, where you can see the “” button.

Now find your modem in the list or network card and make sure they don't have any yellow exclamation marks assigned to them. If you do not find your network equipment (check with your provider for the specific type of equipment) in this list, then most likely the device has failed. If the yellow light appears next to the device description Exclamation point, it means that it is installed incorrectly in the system and you must first reinstall the drivers for it, which are supplied separately by manufacturers and sellers on disks, or on the manufacturers’ websites on the Internet.

4. Incorrect settings

Internet connection settings in operating system carried out on initial stage works Usually you don’t have to return to them after a one-time edit. But it may happen that the settings in the system are mistakenly reset for various reasons. The reason for this may be both the operating system itself and the programs installed in it, including viruses. Human factors cannot be excluded, especially if the computer is used by several users. It may also be that the provider simply changed the Internet connection parameters, but for some reason you were not notified of this.

In any case, it would be correct if you audit the connection settings. To do this, you need to obtain these settings from your provider, or find them if they have already been provided to you. Most providers provide their users detailed instructions for setting up connections. You will only need to “go through” all the points of such instructions again to check the existing connection, or create and configure a new connection, following the instructions in the document. However, more detailed actions I can’t describe it in view of the multitude various options to set up such connections with different providers.

5. Blocking viruses

Another insidious reason for Internet connection interruptions is becoming more and more frequent. Today, there are many types of malicious programs that, hiding in the system, selectively block connections to certain sites or even all Internet traffic on the user’s system. You can verify this, for example, if your connection to large sites fails, but small sites and little-known web pages load without any problems.

Another way to check whether viruses are involved in Internet problems is based on Windows Safe Mode. You just need to hold down the “ F8” just before the operating system starts (before the Windows logo appears) and select the option “ Safe mode with loading network drivers " In this case, there is a high probability that the operating system, having loaded its modules according to the minimum template, will ignore the launch of the blocker virus, which you can verify by working a little on the Internet.

To combat such viruses, use any updated anti-virus system, which is recommended to be launched from an external boot drive. The fact is that some viruses can camouflage themselves and block the actions of antiviruses if they are running on the same operating system. Therefore, to successfully treat your system, it is advisable to connect to it from any other operating system that is known to be free of viruses. If you do not have the ability or proper qualifications to run an antivirus from external system, use at least the same safe Windows mode. In this case, it will be enough to select the option “ Safe mode”, after which you can run installed antivirus for a complete system check.

I wrote in more detail about independently searching for viruses on your computer in the article.

And don’t worry about the fact that if you still haven’t managed to restore your Internet connection, perhaps this is a wonderful reason to go out and visit friends in real life. Let's watch a humorous positive video on this topic.

Owners of 3G modems may encounter a huge number of problems. Some of them are quite easy to solve, but some are not, and one of such problems is related to its spontaneous shutdown.

Owners of 3G modems may be indignant at various reasons: poor connection of the modem, its spontaneous shutdown, unstable pings, etc. Most often, owners of such devices are faced with the spontaneous shutdown of the modem.

If the modem turns off like this, then its owner has to remove the device from the connector again and plug it back in. Naturally, if such a procedure is repeated several times a day, then it cannot but upset a person, and such a problem must be solved somehow. Solving the spontaneous shutdown problem There are several ways to do this. For example, if your 3G modem is connected through a special extender or hub (usually this is done to strengthen the signal and so as not to accidentally break the 3G modem), then you just need to disconnect it from there and connect it to USB port directly on the computer itself. The problem will be solved. If you are not using a connection through a hub or some similar device, then you will need to: open the Start menu, go to Control Panel, and then, in the menu on the left, open Device Manager. In the window that appears, find the “Network devices” item. Various COMs of the modem itself should be located here. You need to open them and in the power settings uncheck the “Allow the device to turn off to save energy” option. After saving changes made, the Internet will work properly, without spontaneous shutdown. Solving other troubles Of course, spontaneous shutdown of the 3G modem is not the only problem. Very often, the signal of such devices disappears or deteriorates greatly. In order to get rid of this problem, you just need to place any speakers in close proximity to the 3G modem. In this case, the signal will increase by approximately 30%. In addition, you don’t have to spend money on buying even the cheapest speakers. The device owner will only need copper wire. You need to open the modem cover and wrap the wire around the device several times in the place where the SIM card is located. After this, the end of the wire is installed at the place where the signal is best caught. This way you can increase the signal up to 95%. If the ping on a device fluctuates, this can only mean one thing - the device is automatically searching for a stable signal. To get rid of this scourge, you need to open a special utility for managing a 3G modem (for example, Megafon-Internet), select “Settings” and “Network”. Here you will need to specify the following parameters: “Network type - WCDMA only”, “Band - GSM900/GSM1800/WCDMA900/WCDMA2100”, “Registration mode - Manual search”. After the update, you need to save the settings and select MegaFon (3G).

When choosing a modem in a store, always pay attention to the data transfer speed, the availability of wireless Wi-Fi networks and signal strength. They often also look at the functionality of the modem and the availability of fine-tuning. However, many people prefer to buy the cheapest modem that suits them, without thinking that it may be unreliable or short-lived.

This is when the problem arises with the modem randomly turning off from time to time. Let's consider the question of why the modem turns off.

Why does a simple modem keep disconnecting?

A regular modem may turn off constantly for several reasons:

• Modem overheating. Usually, low-quality, cheap modems tend to overheat during operation and turn off. If you rock for a long time from the Internet large files, then the modem will begin to overload and overheat. Then it will turn off and go into reboot. In this case, it is better to give preference to reliable branded modems, for example, from Asus.
• The USB cable is loose or damaged. One of common reasons When the modem turns off, it may be that the wire from the modem to the computer is not connected securely and is coming off, or the wire is damaged. In the second case, you should replace the wire and watch the operation of the modem for a while. In the first case, you need to change the connection socket on the computer to a less loose one, because it is known that over time, USB sockets tend to wear out from permanent job with them.
• Software error. The modem may constantly reboot due to an error in software. You will need to reinstall the modem firmware. If there is new firmware, then it is worth downloading and installing it.
• Viruses on the computer. Viruses on your computer can interfere normal operation modem You should install an antivirus and clean your computer from malware.
• The required drivers are missing. In this case, the modem will not be recognized by the computer as a device. You need to install the necessary drivers that come with the modem or install network card drivers.

However, in the case of USB modems from mobile operators Mobile Internet everything may be different. Let's consider the problem of disabling mobile Internet modems.

Why does the mobile modem turn off?

Here are a few standard reasons why a mobile Internet USB modem may turn off from time to time:

• unreliable USB input on the computer. Over time, the sockets can wear out and this can affect the connection mobile modem. You just need to insert the modem into another socket;
• line congestion. It often happens that to one communication tower mobile operator many users can connect simultaneously. Then there will be a problem connecting the modem to mobile internet. The modem may turn off from time to time;
• Modem overheating. Due to downloading a large amount of information, the modem may overheat and turn off;
• viruses can also interfere with the normal operation of the mobile modem;
• The required drivers are not installed. You need to install mobile modem drivers from installation disk or flash drives.

If you are unable to fix the problem yourself, then you should contact a technician at the service center.
