The hotspot on the phone is disabled. Unstable Internet over Wi-Fi: a few tips to solve the problem

Bought a laptop, phone or tablet. A portable device is specially selected to access the Internet via Wi-Fi in any accessible place. However, an unforeseen difficulty arises: for some reason, the connection suddenly disappears. What is the reason? Let's figure it out.

Abrupt and sudden shutdown wireless network can happen due to several reasons. They are presented below:

• Wi-Fi coverage may disappear due to the fact that one of the functions of any modern device Whether it's a laptop, tablet or phone, is battery saving.
• An important reason may be the presence of a weak Wi-Fi signal.
• Another reason is unexpected driver failures, including the driver responsible for the quality of the wireless network.

However, whatever the reasons why Wi-Fi turns off, they are all pretty easy to fix. It is only important to be able to make the necessary settings, or reinstall the driver. In this case, it is best to download the driver from the official website of the manufacturer, otherwise serious problems may arise in Wi-Fi operation. Let's talk about problem solving in more detail.

What to do if there is a weak signal or sources of strong interference?

This factor is a fairly common reason for disabling Wi-Fi communications. Needless to say, this coverage is based on radio signals that can be swayed. It is worth saying directly about the signal level that it is not always stable. It is influenced by several factors, of which the most significant is the voltage in electrical network. A wide variety of electrical devices are involved in creating interference, which can sometimes be so strong that it interferes with the propagation of a Wi-Fi signal.

Even more annoying is the presence of metal objects between the portable device and the router. When the laptop is located at a fairly large distance from the signal propagation point, it may periodically disappear. Therefore Wi-Fi is turned off. As already noted, the signal is not stable.

When a laptop, phone or tablet is located near the router, the fluctuations are imperceptible, and as they move away, they begin to manifest themselves more and more, and as a result WiFi connection breaks off. Communication has a particularly negative impact mobile phones or microwave ovens. You can fix the problem by moving the laptop closer to the wireless router.

Problems Caused by Battery Saving

As you know, one of the fundamental functions of any laptop, tablet and phone is offline work, which is achieved due to high-quality battery saving. In this regard, the developers have created a special program that allows you to save energy, and which automatically turns off modules that are not used for a long time.

The same goes for WiFi adapter. It is quite possible that it will automatically turn off when not in use. However, it happens that the program gives certain failures and, as a result of an unstable connection with Wi-Fi, the adapter turns off after a certain period of time, regardless of whether it is needed in this moment Internet connection or not needed.

You can solve the described problem by disabling the mentioned option. To do this, you need to pay attention to the battery icon in the lower right corner of the screen. Select it and go to " Extra options recharge the battery”, and then set the optimal recharge plan. It is quite possible to experiment here until the optimal plan is found.

Finally, select the "Edit" icon. The Power Saving Modes window appears. Here you need to set maximum performance both when running on battery and when operating from the network. Thus, the automatic disabling of the Wi-Fi adapter will become inactive. As a result, Wi-Fi will not suddenly disappear.

However, what if all the work is done in the right way, but it still happens permanent shutdown WiFi connections? This means that the operating system itself has power saving settings. Disabling this feature is possible using the "Wireless Network and Sharing Center". All you need is to right-click on the "Wi-Fi" icon. Then you should select the required pop-up sub-item - "Change settings". Here you need to find the shortcut for the wireless connection and click on it right click. In "Properties" select "Network". Then you should go to "Settings" and select "Power Management". Here you should uncheck the box "Permission to turn off the device in order to save electricity".

Happy laptop owners sometimes have situations when wifi suddenly turns off and the Internet no longer works. This problem is not uncommon and can constantly arise for completely different reasons. This post will discuss how to solve this problem.

Imagine you are reading a news article, watching an online movie, chatting with friends in instant messengers or through voice communication, when suddenly access to the Internet is turned off, the computer stops seeing an available connection, and precious minutes are constantly spent on its renewal, which are never enough. In this regard, before proceeding with solving the problem of turning off wifi, it is worth understanding some of the reasons leading to this error.

The most common reason for the periodic disconnection of the Internet connection lies in the laptop's system power saving utility. The program, at certain intervals of machine downtime, breaks the wireless connection due to which the Wi-Fi module stops seeing and exchanging data with the router in order to save energy.

An unlikely but valid reason is when the access point is located too far from the receiving device or works behind an obstacle. As a result, the signal strength becomes so weak that wireless adapter laptop is not able to catch it, as a result, the connection is disconnected. That is why it is so important to purchase devices with a powerful transmitter.

Often, the Internet signal transmitted over the cable and converted in the router into wireless connection, too weak and, despite the working Wi-Fi modules, access to the network is impossible. Besides, weak signal cable connection may cause automatic shutdown hotspot and laptop connection.

unstable work wifi router, periodically manifested in reboots and freezes. In such cases wireless device on the computer will do automatic restarts, and the connection will disappear, disconnect and resume again after full recovery access point operation.

Outdated or inappropriate adapter driver wireless wifi Connecting a laptop also causes intermittent disruption, or the computer does not detect available wireless connections at all.

The above problems are the most commonplace, but other reasons also occur and it must be remembered that each specific case is in some way unique and its resolution requires a whole range of measures to restore the lost connection.

Disable power saving mode

Since all laptops have built-in autonomous batteries, they usually come with special programs either used standard means operating system to make power saving efficient. To disable the power saving mode, which is implemented by disabling the wireless adapter, you need to open the "Control Panel" and find the power and power saving icon there. In the window that opens, you need to find and select the power scheme setting. Next, you need to open the link "Change advanced power settings". In the window that opens, open the adapter settings wireless connection, find the "Power Saving Mode" icon and there, change the values ​​​​to the maximum performance mode, in other words, prevent the program from turning off the wireless adapter. Now operating system will not be able to interfere with the wireless connection and interrupt its operation.

Weak access point signal

A variety of obstacles can affect the quality of the wifi router signal, from the walls of rooms to electrical appliances. Often, the cause of signal loss can be a malfunction of the antenna of the transmitting Wi-Fi device.

To eliminate this problem, you should act by trial method. It is necessary to identify the cause of constant interference, gradually moving the laptop away from the distributing access point and checking how the adapter works, because any metal objects contribute to the deterioration or loss of the radio wave signal.

Signal propagation

If there is a suspicion of a weak signal coming over the wire from the provider, then you should contact the customer support service and find out the cause of the problem, which is why access to the Runet is lost. When we are talking about the network provided mobile operator, then it may be worth trying to amplify the signal by changing the localization of the transmitting device.

WiFi distributor problems

In case of obvious problems with a wifi router, a series of reboots can help. If the device does not work as required and continues to disconnect, you can, as an option, check the settings of the access point, perhaps the provider has changed some parameters. You can also check for updates on the hardware manufacturer's website and, if available, update the software through the settings menu.

Problems in drivers

If the working machine is not the first freshness, then why not check for updates, perhaps you should think about installing a fresh one wifi drivers network devices. To do this, you need to know the manufacturer network adapter and download new version from its official website, and then install it on a personal computer.

If you have any problems related to turning off Wi-Fi, you should use the above tips and only then, it may make sense to contact a specialized service center for detailed equipment diagnostics. Now you know why wireless connection can be torn and able to find a solution to this problem.

Today it is already impossible to imagine any apartment or office without its own Wi-Fi network. Having a router is no longer a luxury, but commonplace. But every user sooner or later faces a problem when Wi-Fi is turned off on the phone. Why is this happening? Is this a technical problem or just carelessness in use? The article will talk about the main types of errors and how to eliminate them.

Problems with connection

In 99% of cases, Wi-Fi connection problems are caused by the following reasons:

• Incorrect work router.
• WiFi settings errors.
• Availability third party programs installed on the device.
• Incorrect phone settings.

Correct diagnosis will help solve the problem. In most cases, you can do it yourself, without resorting to the help of specialists. Slow work Internet, for example, may indicate that there has been network congestion, as too many devices are connected.

Settings errors

The first thing you should pay attention to is the settings of the Wi-Fi access point itself. You can check the correct operation through the menu of the router, which can be accessed through the browser. To do this, you need to know the username and password of the user, which are either written on the router itself, or, if they have already been changed, you need to find out on your own or reset the settings. Once the menu is accessed, it is necessary to find out the parameters wireless mode, such as:

• Channel width (set from 5 to 40 MHz).
• Channel selection (configured automatically, but you can choose yourself).
• Baud rate (set to the maximum value).
• Region (may be the cause of the problem, but very rarely, so it is better not to change this item).

Everything is set correctly, but why does the Wi-Fi on the phone turn off? You need to move on to the next item.

Incorrect operation of the router

If using the router settings menu it was not possible to determine why the Wi-Fi is turned off on the phone, you need to check the operation of the router itself.

Indicators will prompt the user for correct operation. Usually there are three or four of them, depending on the model, and they should all be on or flashing:

• Nutrition. On different models color may vary (green, blue, but not red). But it should always be on, not flashing.
• The system indicator is always blinking.
• The WAN indicator is an indicator of the presence of an Internet network.
• WLAN pointer - shows whether the wireless network is running on the router itself.
• After them come the LAN ports to which the cable is connected for wired internet. They do not affect the operation of Wi-Fi.

The router also has a power button with which you can restart the device. This trick helps a lot of people.

The presence of third-party programs installed on the device

Viruses are one of the main problems of the Internet. Because of them, Wi-Fi on the phone is periodically turned off. Why does this happen and how to avoid it? If there is a suspicion that the device has been subjected to a virus attack, it is recommended to install one of the many antivirus programs and run the check. The program itself will find viruses known to it and eliminate them.

But such security programs are often themselves a problem for Internet access. Therefore, there is no need to constantly keep the antivirus turned on.

Incorrect phone settings

If the device has an unlicensed or broken software, then you should not be surprised that Wi-Fi is turned off. For some reason, this problem happens less often on Samsung phones. Perhaps because the manufacturer fully provides devices with high-quality software. But even in this case, the user can accidentally or deliberately change the factory settings. This problem can only be solved full reset To initial settings. With "native" firmware, problems with Wi-Fi are extremely rare, since it is not subject to third-party influences. But in this case, the user will lose all their data, so important information Save before resetting.

Wi-Fi connection problems can often be solved on your own. But physical intervention and repair can permanently damage the device. If the available methods failed to determine why the Wi-Fi is turned off on the phone, you should contact the technical support centers.

Wi-Fi is a technology that allows electronic devices to transmit data or connect to the Internet wirelessly. Nowadays, Wi-Fi usage is becoming very common and we can see this technology being used by a wide range of devices such as smartphones, tablets, game consoles, smart TVs, etc.

However, this technology has a number of limitations. Firstly, it is not as secure as a wired connection, but this is solved by using Protected Access Encryption (WPA2), which helps prevent unauthorized access to the network. If you do not have sufficient knowledge to set up a home or office network it is better to entrust this matter to professionals. Simply fill out the form at http://kompom.kiev.ua/ and the setup will be done quickly and efficiently.

Another problem: Wi-Fi periodically disappears. Usually, if there is no activity, the phone or tablet loses connection with the wifi router and does not see the network until Wi-Fi is restarted on the mobile device. There may be several reasons why the Wi-Fi connection is lost, in this article we will consider several options for solving the problem when Android loses the Wi-Fi network.

If you are facing Wi-Fi disconnection problem on your Android device, try the following settings and you will be able to connect your device wirelessly without much hassle.

Wi-Fi network overflow

The biggest interference to the Wi-Fi signal is created by neighboring wireless networks. The problem is that most WiFi devices operate in the already occupied 2.4 GHz band, and high density signals can interfere with each other reducing the speed and performance of networks.

Solution: Use a dual-band router that can operate on both 2.4GHz and 5GHz at the same time. The 2.4GHz band will be supported by most devices, but it only has three non-overlapping channels. On the other hand, 5 GHz has 23 non-overlapping channels, increasing the likelihood of no interference on this band. If your router can operate in the 5 GHz band, use it to solve the problem of Wi-Fi network congestion.

Setting up a Wi-Fi channel

The 2.4 GHz Wi-Fi band has 11 channels and each of them is separated from each other by a 5 MHz band and has a width of 20 to 22 MHz. This means that each channel will overlap adjacent channels by 10 MHz and this is referred to as overlapping channels.

Solution: If channels 1, 6 and 11 are used, there will be no interfering overlap as these are non-overlapping channels. To work on these channels, users will need to go into the router's settings and find a setting called "Channel" or "Wireless Channel". From the dropdown menu, select desired number channel.

Most manufacturers resort to various methods to increase battery life. Users Android smartphones are forced to enable such power-saving features in their devices. One such feature is turning off Wi-Fi when the phone is inactive or when the device has a low battery level. Such features of Wi-Fi in sleep mode create problems when connecting to the network as needed.

Solution: Just adjust your Android device's settings and make sure you always have Wi-Fi turned on, even when your device is not in use. To do this on devices running Android 2.3 Gingerbread and above, you need to do the following. Go to Settings menu - Wireless network- Wi-Fi and select Advanced - WiFi in sleep mode do not select "Do not turn off".

On those devices running Android 4.0 ICS and above, go to Settings - Wi-Fi, select Advanced and set the option Wi-Fi during sleep - "Always".

Change DNS servers

Changing DNS servers can solve wifi problem when the Internet network on the phone disappears. Go to Settings - Wi-Fi and turn on Wi-Fi. If it's a known network, you'll have to "forget" it and then reconnect. When you see the password entry window, click on Extra options and select "Static" from the IP settings in the drop down menu. Then scroll down and enter the IP address of the DNS server you would like to use in the DNS1 and DNS2 box. Now enter wifi password and connect the network.

Reset to factory settings

If none of these methods help, perform a hard reset on your Android device. If you're having issues after doing this where your Wi-Fi connection is lost, then it could be a hardware issue. You may need to take your device to a service center to have the problem fixed.

We have looked at the most common reasons for Wi-Fi disconnection that occur in Android devices. We hope this will help in solving the problem and allow you to set up a stable Wi-Fi connection. Also, pay attention to specialized applications, since the store Google Play There are many applications that can be used to help ensure a secure connection. Some of them are Wi-Fi Fixer, Fix My Wi-Fi, Wi-Fi Analyzer and others.

Recently, I began to notice that the more people buy different equipment with WiFi - routers, modems, access points, TVs, tablets, etc. - the more problems arise with the wireless network: the signal disappears or it is very low, the data transfer rate jumps or it is very small, devices periodically fall off and can no longer connect. There are many reasons why Wi-Fi turns off, and it can be like software settings as well as hardware failure. In general, the wireless network itself is a very capricious thing, the stability of which depends on many factors and conditions. Today I will talk about the most common problems and failures due to which poor reception or even disappears wifi signal.

Wifi signal dropped suddenly

turned off the router. Try restarting it by turning off the power for a couple of minutes and turning it back on.

- If you have a laptop or tablet, check the battery charge. On many mobile devices to save energy, the Wi-Fi module can be forcibly disabled. Moreover, on laptops with Windows 8 and Windows 10, this option is often enabled in the properties of the adapter.

Also, it is worth checking the settings of the power supply scheme used.

- Approach the router at a distance of about 2 meters. No signal? Then you need to test a known working device with a wireless network interface– tablet, smartphone, phone, etc. If it works without problems, and your laptop cannot connect, then most likely it has a problem with the adapter driver. Try reinstalling or updating it.

Didn't help and WiFi is turned off on the laptop anyway? Take it to the service.
By the way, on laptops and tablets, there is often a case when, due to poor contact, the antenna turns off during shaking. In this case, you need to open the case and solder it back.

If the test device also does not see the home network, then the problem is on the side of the router. Try to reset its settings to the factory settings using the "Reset" button and set it up again.

If it doesn't work, take it in for repair.

Poor or unstable Wi-Fi signal strength

The reason for the degradation of the quality of the wireless home network the most common is the presence in the neighborhood of several more access points. This is another common reason why Wi-Fi turns off. lately in apartment buildings this is some kind of punishment. There is a router in almost every apartment, and in every entrance there are a dozen or two networks. In this case, there are two ways out: the right one and the cheap one.
—Correct option but more expensive. Why? And because you have to buy equipment operating at a frequency of 5 GHz, since now it is already relatively inexpensive. An inexpensive dual-band router will cost about 3 thousand rubles. For example, Totolink A2004NS router.

I think it’s clear that a computer and a laptop will also need to be bought additional adapters - that’s a couple of thousand more. But things are worse with smartphones and tablets - some already have support for the 5 GHz band, but simpler and cheaper ones will have to be left in the old range. But there will be no more problems with channel overlap and interference from neighbors.
- A cheap option - time-consuming and hemorrhoids. Firstly, you will need to constantly scan the range with the inSSIDer program in search of a free channel, and then set it in the router settings.

Secondly, most devices will still have to be dragged closer to the modem or router, since even if the selected channel is free, the interference can come from busy neighbors. And you can't get away from it. Just wrap the house with foil in 5 layers.

I have no networks in the neighborhood, but WiFi still turns off. Why?

In this case, the most common reason is the incorrect location of the access point in the apartment. To provide it with the maximum coverage area, it should be located as close to the center of the dwelling as possible. If you have points where Wi-Fi from the router still does not finish, then you need to install an additional device - a repeater.

The signal quality of a wireless network is greatly affected by:
- drywall (walls made of it or their finishing with drywall)
— reinforced concrete walls(reinforcement has a critical effect)
- water. Very often in houses or apartments they like to put a large, large aquarium against the wall. After that, a pandemonium with the network may begin in the next room and the owner will be visited by the question “why is Wi-Fi turning off ?!”
— electronic devices . If in the space between the router and the computer (laptop, tablet, smartphone) there is a lot of electronics (TVs, microwaves, radio stations) and the like, then you will immediately notice a deterioration in the quality of work.

Do not forget that the reason that WiFi is turned off can be software or hardware router malfunction.

In my memory, there is one case with D-Link DIR-615 K2. The owner complained to me - "Wi-Fi disappears!". I checked the settings - everything is correct. But after some time, the access point simply turns off. And through the LAN ports of the router everything works fine. The solution was a simple firmware update, after which the problem was safely eliminated.
Another case was with a device from QTech, where the contact of the internal antenna fell off when it fell off the table. The manufacturer took pity on the solder. Opened, soldered the antenna and WiFi does not disappear. Although, if you are not friends with a soldering iron, then if you suspect that Wi-Fi disappears due to a hardware malfunction, take the device to a service center.
