Why does the Internet turn off? Why is my mobile phone call being dropped? Adsl modem internet interrupts when calling

and Android.

Many users encounter a problem when phone or The 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 interrupted or ends on its own. The reason for this may be:

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

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

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

Fixing a software glitch:

Method 1. Quite simple - go to "settings", find there "backup and reset", in which you choose full reset settings with deletion of all data. Be careful, using this method is often 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 even after this the problem is not resolved, see Method 2.

Method 2.

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

• In addition, it is worth cleaning the system using a NORMAL antivirus. Best suited for this task Kaspersky antivirus , which you can download. Unlike the “multi-cleaner”, the Kaspersky Lab software is paid, therefore, if you do not 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 can be resolved by contacting the Service Center. To carry out this task yourself, you need to contact the website of the manufacturer of your device, download the utilities necessary for flashing the firmware and the firmware itself, and then reinstall it on your gadget.

If none of the methods brings results, unfortunately, you will have to contact Service center For repairing your tablet a or smartphone a.

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

If there is no way or don’t want to talk, subscribers resort to different methods.

The most simple reason, through which it is impossible to reach the subscriber - his phone is turned off, or the subscriber himself is outside the network coverage area.

If the call goes through, but the subscriber 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 took advantage of the capabilities of his smartphone by selecting the “priority” option. For example, owners of Sony devices have this 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, passing only those that are in the address book.

The “black list” created by the subscriber will prevent unwanted people from calling him. If an outgoing call only rings once 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 connection 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 outgoing call is reset immediately, and the caller does not hear a single beep.
In this case, it is possible that the subscriber used the services of a cellular operator and turned off all incoming calls; I activated the “call barring while roaming” service. In this case, the subscriber can receive SMS messages (that is, they can reach the subscriber), if they have not been disabled.

The “call barring” service (the so-called “black list”), not only incoming but also outgoing, is offered by all cellular operators.

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

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 redirected to a SIM card that simply does not work.

There are times when it is impossible to reach a subscriber because “blocking 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 can be made.
If there is a problem with your smartphone that it does not allow outgoing calls, you can reboot it (this is useful to do periodically), as well as turn off/on the 3G function (this may be due to the “raw” firmware).

For the Android operating system, a program has long been invented that cuts off unnecessary incoming calls or redirects the caller to voicemail. 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 turning on the “black list” option, without specific numbers in it, does not allow you to reach the subscriber, and only when it is turned off do calls go through, but this is an isolated opinion that needs to be verified.

Unstable operation of the Internet using ADSL technology is usually 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 topology for connecting the modem in the apartment.

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

We are trying to fix the problem ourselves

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 section of the circuit in front of the splitter; the result is that when the telephone 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 them and wrap the twist with insulating tape;
• The splitter may be faulty. To see if this is true, connect the line from the telephone socket directly to the modem and observe.

If the methods described above do not produce results, please contact technical support your ISP, they will send an electrician to troubleshoot the problem. Believe me, you most likely won’t be able to do anything else on your own.

A little theory, or why the DSL connection disappears

An ADSL profile is installed on each ADSL port supplied from the PBX to the telephone line. 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 more good quality or lesser extent. I understand that it’s difficult to understand, but you try.

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

Let me give you an example. In the screenshot below is the Status tab, from the WEB interface of the D-LINK ADSL modem. 8128 Kbps is the speed at which the modem is linked. And the profile on the port is set to 10000 Kbps. 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 body. lines. True, there is one BUT! The link speed must be at least 1 Mbit/s higher than the speed tariff plan subscriber And of course, only technical staff can do this. support (with the help of special software, which they use to moderate the equipment on the PBX). Well, if you are a subscriber, then you can easily pass for one of your own by flashing such information when calling the same tech. support.

Let's go back to the screenshot. I set the profile to 8064 Kbps on the port. All! 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?

Georgiy 2014-10-30 03:08:01 Hello! Three questions arose. I live near St. Petersburg, connected to Rostelecom ADSL, but it often went out even at a speed of 4 Mbit/s. They advised us to switch to a speed of 2 Mbit/s due to the fact that the channel could not withstand the load. But now this Internet also cuts out after a while or does not connect at all, DSL is constantly blinking. The TP said that there was a signal and that I needed to check my equipment, although I had already checked the working modem and working router. In the neighboring house, the same Internet with the same modems works fine. 1st question - can speed affect DSL connection breaks? Second question: how and where to set the speed on the port described in the article, and will this help? 3rd question - is it worth bothering the TP with checking the 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. The speed can only be set by the provider’s TP; you most likely have already set it to 2 Mbit, since they advised you to reduce the speed of your tariff plan. The answer is yes, it will most likely help, but the speed will have to be reduced further. 3. Problems are most likely with the line, but it’s up to you to decide whether to torment the provider or not. The length, integrity and general condition of the copper pair are the three pillars on which ADSL rests. In any case, it’s worth calling TP and submitting an application. [Reply] [Cancel reply]

All Internet users dream of its uninterrupted operation. Unfortunately, everything that can be turned off in technology always turns off at the most inopportune moment. This can cause a nervous breakdown, and you need to understand communication problems in order to eliminate them in a timely manner.

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

Today it is quite rare when accessed via an ADSL modem telephone line not highlighted. Still occurs direct connection phone not through a microfilter or splitter. When talking on the handset, you will hear hissing and crackling noises if the modem is turned on. Reconnection will occur when an incoming call is received, a number is dialed, and when the user picks up and hangs up the handset. In any case, while communicating by phone, access to the Internet will not be blocked. When using a GSM network, data is transmitted over free channels using the GPRS protocol. Higher priority is given to voice messages. If the number of subscribers wanting to talk increases, there are no free channels left and Internet access is closed. The connection is broken due to the exchange of messages, the sending of USSD commands, and the decision of the phone owner to make an outgoing call. The situation is much better in 3G networks. Compared to the GSM network, the quality of their communication is many times better. They made simultaneous voice communication and data transmission possible. In such networks, traffic costs less, which is due to the low cost of unlimited mobile internet. If the subscriber is on the move, he moves from one station to another. Some of them do not support 3G. Access may be terminated when changing stations. Interruptions are sometimes forced by cellular operators. Access to the Internet via Wi-Fi is interrupted when moving within 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, for example, 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 maintenance. The cable between the station and the subscriber can be physically damaged at any point. Replace your network card if it is damaged. When purchasing, consult with specialists; the card may conflict with other devices. Overheating of the processor, power supply cannot cope with the load, presence of dust in the system unit, insufficient RAM– can also cause “bad” Internet.

Check your connection settings. Reinstall your operating system. Poor connection persists? This means that you should call your provider; perhaps they have control over MAC addresses. After reporting the new MAC address to the support service, communication with the Internet will resume. In any case, it’s worth calling the provider. The line problems will be resolved soon.
