Internet drops out when phone rings. The conversation (call) is interrupted when calling from a smartphone or Android tablet. Trying to fix the problem on our own

If there is no opportunity or do not want to talk, subscribers resort to different methods.

The simplest reason why it is impossible to reach the subscriber is that his phone is turned off, or the subscriber himself is out of the network coverage area.

If the call goes through, but the caller does not pick up the phone, it is possible that he cannot / does not want to talk, or his smartphone is in silent mode, or the person has used the capabilities of his smartphone by selecting the "priority" option. For example, owners of Sony devices have such an opportunity - by adjusting the volume of the smartphone, you can select one of the modes "silent", "priority", "sound". Just the "priority" option allows you to filter calls, skipping only those that are in the address book.

The "black list" formed by the subscriber will not allow unwanted people to get through to him. If only one beep passes during an outgoing call, and then the call is dropped, the caller is probably on such a list; or he hears short beeps, as if the number is busy, or the message "the subscriber's device is turned off or is out of network coverage."

This type of communication is not available to the subscriber. What does this mean? - www.site/all_question/other/2016/April/72499/187718

And a completely different picture, if the outgoing call is dropped immediately, and the caller does not hear a single beep.
In this case, it is possible that the subscriber used the services of a mobile operator and turned off all incoming calls; activated the service "prohibition of receiving calls in roaming". In this case, the subscriber can receive SMS messages (that is, they can reach the subscriber), if he has not disabled them too.

The "call barring" service (the so-called "black list"), not only incoming, but also outgoing, is offered to be connected by all mobile operators.

After the service is activated, you can independently add those numbers that are considered as such to the list for unwanted calls. It is also possible to block an unwanted number permanently.

The inability to reach the subscriber may be due to the fact that he has the iVoiceCallMaster program installed, with the help of which all unnecessary or unwanted numbers are forwarded to a SIM card that simply does not work.

There are cases when you can not get through to the subscriber, because the "blocking of incoming / outgoing calls" is enabled in the settings of his smartphone.
For an iPhone, it helps to enable the "show my number" option in the settings so that calls go through.
If the problem with your smartphone is that it does not miss outgoing calls, you can restart it (it is useful to do this periodically), as well as turn off / on the 3G function (maybe it's a "raw" firmware).

For the Android operating system, a program has long been invented that cuts off unnecessary incoming calls or redirects the caller to voice mail. The program is called Current Caller ID and is suitable not only for smartphones, but also for tablets. To take advantage of this opportunity, the Current Caller ID application must be installed on your gadget.

There is an opinion on the Internet that simply the "black list" option, without specific numbers in it, does not allow you to reach the subscriber, and only when it is turned off, the calls go through, but this is a single opinion that needs to be verified.

All Internet users dream of its smooth operation. Unfortunately, everything that can be turned off in technology is necessarily turned off at the most inopportune moment. This can cause a nervous breakdown, and communication problems need to be sorted out in order to eliminate them in a timely manner.

The most elementary reason for disconnecting the Internet, which must be checked first of all, is virus activity in the system. A thorough scan of your computer with an antivirus will help. Small-looking, harmless files can host in it and disable not only the network, but also important OS components. Even powerful scan programs can miss pests, so use several different antiviruses. Details in the article "". If the computer is connected to the network via an ADSL modem, then there may be several reasons for the poor connection. The computer's dynamic IP address must be changed once a day. At this time, the subscriber's connection with the network is interrupted. Such a gap is not noticeable to the user if his modem is combined with a router. The disconnection lasts for a few seconds, during which an automatic reconnection occurs. There is no message about this on the screen.

Today, it is quite rare when accessing via an ADSL modem, a telephone line is not allocated. Nevertheless, there is a direct connection of the phone not through a microfilter or splitter. When talking on the handset, hissing and crackling will be heard if the modem is turned on. Reconnection will be performed when there is an incoming call, when a number is dialed, and when the user picks up and hangs up the handset. In any case, while talking on the phone, access to the Internet will not be closed. When using a GSM network, data is transmitted via free channels using the GPRS protocol. Higher priority is given to voice messages. In the event of an increase in the number of subscribers who want to talk, there are no free channels left, Internet access is closed. Disconnection causes messaging, sending USSD commands, the decision of the owner of the phone to make an outgoing call. The situation is much better in 3G networks. Compared to the GSM network, the quality of their connection is many times better. In them simultaneous voice communication and data transmission became possible. In such networks, traffic costs less, which is the reason for the low cost of unlimited mobile Internet. If the subscriber is on the move, then he moves from one station to another. Some of them do not support 3G. Access may be terminated at the time of changing stations. Interruption is sometimes forced by cellular operators. Internet access via Wi-Fi is interrupted at a distance of 10 meters from the source. The frequency with which the router emits a signal is 2.4 GHz. It is approximately equal to the frequency of the light source. It is easy to block it with some object, such as a wall, so signal reception becomes unstable.

Access to the Internet via twisted pair is interrupted due to the fault of the provider or subscriber if the network card is faulty. Providers periodically carry out preventive work. The cable between the station and the subscriber can be physically damaged in any area. Replace your network card if it is damaged. When buying, consult with experts, the card may conflict with other devices. Overheating of the processor, the power supply unit can not cope with the load, the presence of dust in the system unit, not enough RAM - can also cause a "bad" Internet.

Check your connection settings. Reinstall your operating system. Bad connection not fixed? So, call the provider, maybe he has control over MAC addresses. After reporting the new MAC address to the support service, Internet connection will resume. In any case, a call to the provider is worth making. Line problems will be fixed soon.

Unstable operation of the Internet using ADSL technology, as a rule, is associated with a drop in the DSL link. In 95% of cases, this problem occurs due to a poor-quality telephone line and / or an incorrect modem connection topology in the apartment.

The remaining 5% is due to a failure of the station or subscriber equipment (modem or splitter is faulty). In this article, I will try to tell you how you can make the connection more stable.

Trying to fix the problem on our own

If you notice that the link is unstable, you can try to fix the problem yourself. Here are some tips:

• Check in your apartment whether the modem is connected correctly. You can see the connection diagram. Very often, subscribers install an additional telephone set in the circuit section in front of the splitter, the result is that when the handset is picked up, the link disappears. Why? Off-hook = line short circuit;
• Check all the twists of copper wires in the apartment, perhaps the contact somewhere is not very good. If you find such a connection, strip the wires, connect and wrap the twist with insulating tape;
• The splitter may be defective. To see if this is the case, connect the line from the telephone jack directly to the modem and observe.

If the methods described above did not work, then contact the technical support of your Internet provider, they will send an electrician to troubleshoot. Believe me, to do something else on your own, you most likely will not succeed.

A bit of theory, or why the DSL connection disappears

For each ADSL port supplied from the PBX to the telephone line, an ADSL profile is installed. This profile determines the link speed, that is, the speed at which the modem will link. And if the line is of poor quality, then it will not withstand the profile that requires a line of better quality or shorter length. I know it's hard to understand, but just try.

What's the point? Yes, in that if the profile is not maintained, then the link will constantly disappear, tk. the modem tries to link to the profile that is set on the port.

I'll give you an example. In the screenshot below, the Status tab, from the WEB interface of the D-LINK ADSL modem. 8128 Kbps is the speed at which the modem was linked. And the profile on the port is set to 10000 Kbps. The link will fall.

In such a situation (and indeed in almost all situations), problems with the link can be solved by changing the profile to a more suitable one for your bodies. lines. True, there is one BUT! The link speed must be at least 1 Mbps higher than the speed of the subscriber's tariff plan. And of course, only those employees can do this. support (with the help of special software with which they moderate the equipment on the PBX). Well, if you are a subscriber, then you can easily pass for your own, flashing such information when calling the same tech. support.

Let's go back to the screenshot. I set the port profile to 8064 Kbps. Everything! Now the connection will be stable. For the time being, of course, until the line parameters become even worse.

Thank you all for your attention. Questions?

George 2014-10-30 03:08:01 Hello! Three questions arose. I live near St. Petersburg, Rostelecom connected ADSL, but it was often cut down even at a speed of 4 Mbps. They advised to switch to a speed of 2 Mbps due to the fact that the channel cannot withstand the load. But now this Internet is also cut down after a while or does not connect at all, DSL is constantly flashing. The TP said that there was a signal and that my equipment should be checked, although I had already checked a working modem and a working router. In a neighboring house, the same Internet with the same modems works fine. 1st question - can speed affect DSL connection drops? 2nd question - how and where to set the speed on the port described in the article, and will it help? 3rd question - is it worth tormenting the TP with checking cables in the attic of the house? [Reply] [Cancel reply] Admin 2014-10-30 08:38:02 1. Breaks are affected by the load on the line when the modem tries to link at a speed that the line cannot withstand. The answer is yes, you can say that. 2. Only the provider's TP can set the speed, you most likely already have 2 Mbps set, since they advised to reduce the speed of the tariff plan. The answer is yes, it will most likely help, but the speed will still have to be lowered. 3. Problems are most likely with the line, but whether to torment the provider or not is up to you. The length, integrity and general condition of the copper pair are the three pillars on which ADSL rests. Calling the TP and submitting an application, in any case, is worth it.

and Android.

Many users face the problem when phone either android tablet starts acting up. It seems that nothing happened that could cause a malfunction, but it does not work as it should.

For example, the device has problems with the fact that the call is constantly or periodically terminated or ends by itself. The reason for this may be:

1st: Software failure- i.e. the problem is a software glitch

2nd: hardware failure- i.e. the problem lies in the "hardware" (i.e. - replacement or restoration of spare parts of the gadget is required)

However, do not rush to get upset - in 90% of cases with problems connections on call smartphone a or android tablet is to blame software failure, which you can fix on your own.

Fixing a software bug:

Method 1. Pretty simple - go to "settings", find there "backup and reset" in which you choose full reset settings to delete all data. Be careful, using this method often turns out to be effective, but it entails deleting all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone e or tablet e. Therefore, first save everything you need by connecting the gadget to your computer. If this method does not suit you, or if the problem persists after it, see Method 2.

Method 2.

Based on solving problems with communication and network reception phone ov and tablets based on Android by introducing additional software. Utilities that control all processes inside gadgets. Today, there are quite a few of them, however, the fewer functions an application contains, the more, as a rule, it is effective. Best of all, it controls the system functions, corrects, and fixes all possible settings and synchronization errors, a small, easy-to-use, free utility for Android devices. You can download the application from Google Play and see its additional options in the description. After installing the application, it remains only to launch it. Further, from you, in principle, nothing more is required. The application will take full control of the device functions. (By the way, among other things, the gadget will start charging 20% ​​faster, and its performance will also increase significantly, which will affect the loading and operation speed of all applications, games, and the system as a whole. On average, after scanning, the system runs on 50% faster.)

• In addition, it is worth cleaning the system with a NORMAL antivirus. Best of all, it copes with this task kaspersky antivirus , which you can download. Unlike the “multi-cleaner”, Kaspersky Lab’s software is paid, so if you don’t have the opportunity to install such protection, you can skip this step ...

Method 3.

Changing the device software, or, as it is also called "re firmware ". This method, as a rule, requires certain skills and is solved by contacting the Service Center. For the independent implementation of this task, you need to contact the manufacturer's website of your device, download the utilities necessary for the firmware and the firmware itself, and then reinstall it on your gadget.

If none of the methods brought results, unfortunately, you will have to contact the Service Center for repair of your tablet a or smartphone a.

The conversation (call) is interrupted when calling from a smartphone or Android tablet.
