Android wifi turns on automatically. Solving the problem of self-activation of Wi-Fi

Facebook

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

Sharp and sudden shutdown wireless network problems 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 to save battery power.
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 high-quality operation of the wireless network.

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

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

This factor is quite common cause turning off Wi-Fi connection. Needless to say, this coverage is based on radio signals that can be shaken. It’s worth saying directly about the signal level that it is not always stable. It is influenced by several factors, the most significant of which is tension in electrical network. The most diverse electrical devices are involved in creating interference, which can sometimes be so strong that it interferes with the propagation of the Wi-Fi signal.

The presence of metal objects between the portable device and the router can be even more disruptive. If the laptop is located at a fairly large distance from the signal propagation point, it may periodically disappear. Therefore Wi-Fi turns off. As already noted, the signal is not stable.

When a laptop, phone or tablet is placed close to the router, the vibrations are unnoticeable, but when moving away they begin to become more pronounced, and eventually Wi-Fi connection breaks off. Mobile phones or microwave ovens have a particularly negative impact on communications. 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 autonomous operation, which is achieved due to high-quality battery saving. In this regard, the developers created special program, which allows you to save energy and which automatically turns off modules not used for a long time.

The same applies to the Wi-Fi adapter. It is quite possible that it will turn off spontaneously if it is not in use. However, it happens that the program gives certain glitches 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 this moment Internet connection or not needed.

You can solve the problem described 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. Having selected it, you should go to “ Extra options recharge the battery" and then ask optimal plan recharge. Here it is quite possible to experiment until the optimal plan is found.

Finally, you need to select the “Edit” icon. The Energy Saving Modes window appears. Here you need to ask maximum performance both when operating from a battery and when operating from the network. Thus, automatic turning off Wi-Fi adapter will become inactive. As a result, Wi-Fi will not suddenly disappear.

However, what if all the work has been done correctly, but still there is a constant shutdown? Wi-Fi connections? This means that the operating system itself has power saving settings. You can disable this feature using the Wireless Network Control Center. shared access" All you need to do is right-click on the “Wi-Fi” icon. Then you should select the required pop-up sub-item - “Change parameters”. Here you need to find the wireless connection shortcut and click on it right click. In “Properties” you should select “Network”. Then you should go to “Settings” and select “Power Management”. Here you should uncheck the box “Allowing a device to turn off to save power”.

In this article, we will figure out why Wi-Fi on Android does not turn on and what can be done about it.

Users often encounter the problem that Wi-Fi on their phones does not turn on. In fact, the problem is completely solvable, try the methods described below.

The article was written for owners Samsung smartphones, but many techniques are suitable for all Androids.

Why Wi-Fi does not connect on Android - the most common reasons

The first reason is lack random access memory. Check the RAM status, free space must be at least 45 MB - only in this case can we say something about normal operation Wi-Fi.

The second reason is that the energy saving mode is turned on.

Let's start solving the Wi-Fi problem

Cleaning RAM

Go to the memory menu and perform two-level cleaning:

1. At the first stage, all running processes. Approximately 800 MB of memory should be freed.

2. At the second stage, applications running in background(believe me, this saved more than one user).

Restarting the phone

Don’t confuse this with a reboot, we’ll talk about that later.

Restarting is done like this:
turn on the “Flight” mode;
turn off your smartphone;
remove the battery for five minutes;
Without inserting the battery, press the on/off button for a minute;
replace the battery, turn on the smartphone;
now check if Wi-Fi connects.

Turn off power saving mode

To do this:

Open the dialer;
dial *#0011#
in the maintenance mode that opens, press Menu;
click on WIFI;
turn off power saving mode (in many Galaxy devices it is enabled by default).

Checking the "In Flight" mode

Just in case, check if this mode is enabled. If yes, turn off and turn on Wi-Fi again.

In principle, it’s difficult to miss the enabled “In Flight” mode, because other restrictions arise, but it doesn’t hurt to check again.

Update the firmware and change the router channel

Go to the router's IP address:

Linksys – http://192.168.1.1
3Com – http://192.168.1.1
D-Link – http://192.168.0.1
Belkin – http://192.168.2.1
Netgear - http://192.168.0.1.

After logging in, go to the wireless network settings and set the desired channel.

You can find out which one to choose using the wifi analyzer on your Android, or you can choose a channel between 4-7. These channels work best in most places.

After changing the channel, go to Advanced and click on Firmware Upgrade.

Disconnect all devices

You've probably heard about an IP conflict, when several network users share the same IP - this can block the data flow.

What should be done:
disconnect all devices from the router: smartphones, tablets and computers;
turn off the router for a minute;
turn on the router again and connect only one device to it;
If the connection is successful, connect other devices.

Rebooting the smartphone

Rebooting means completely disconnecting the phone from the power source. In some cases this works.

If there removable battery, remove it (just make sure it is not connected to charger), set aside for 1-2 minutes and then return to place. Turn on the device, check that Wi-Fi is connected.

If the battery cannot be removed, you can restart the phone in another way: hold down the on/off button for 10–20 seconds.

Checking our applications

Sometimes Wi-Fi problem appears due to third-party applications. If you remember after which application you downloaded your phone stopped connecting to Wi-Fi, try deleting it.

If you don't know which program to use, go to safe mode(All third party applications disconnect) and check your Wi-Fi.

If there is, then the problem is in some program. Try to identify it and remove it. Or reset to factory settings.

How to enter safe mode:

Press and hold the phone's on/off button for a few seconds and a menu should appear;
select safe mode ( safe mode);
confirm entry - ok.

How to return to factory settings:

Setting – Accounts tab ( Accounts) – Backup and reset – Factory data reset(Data reset).

Before performing a data reset, back up all important information, because after the operation your phone will be like out of the box.

How to do backup copy data. There are several ways:

1. Using the familiar Kies program (often used to update software on Galaxy devices).

2. Using a Google account: Settings – General – Backup & Reset.

Two options will be offered here: backup And automatic recovery. Select them and passwords, application data, Google settings, bookmarks, etc. will be copied to the Google server.

3. When Samsung help account: Application – Settings – User and backup(User and Backup) – Account. Make sure you are logged in Samsung account. If the option is enabled, your contacts, calendar, and Internet settings will be synchronized.

From the experience of one of the users, developer Timmavajjula

“After the fourth reboot of the smartphone, I noticed that at the second stage of startup, when asked about connecting to Wi-Fi, the presence of networks is checked and it is possible to connect to one of them.

If you notice the same thing, reset to factory settings, and when the smartphone asks for registration with Samsung and Google, be sure to select the option to restore data from the server (although it seems to me that the problem is with Samsung).

Everything is fine with Wi-Fi now. There is no need to go to Settings – Accounts and manually set backup/restore separately for Google and Samsung. When I did as I wrote, the problem did not recur.”

Follow these points:
1. Press and hold wifi icon– until you see the Smart Network Switch Window.
2. Go to the field to the left of the Home button.
3. Click on Advanced.
4. Make sure it says Always Allow Scanning.
5. Try connecting to Wi-Fi. Everything should be ok.
The above tips apply to all Samsung and Android devices, including Galaxy S2, Galaxy S3, S4, S6, S7, Galaxy S6 and S7 Edge. If all else fails, you should take the device for diagnostics to the nearest service center.

How to turn it on or offWi– Fion Android

Let’s say right away that everything is solved simply:

go to the settings menu, which is hidden behind the “curtain”;
find the Wi-Fi item, you will see a switch here;
Slide the switch to turn wireless network access on or off.

How to turn it on or offWi– FioniOS

Turning Wi-Fi on/off on iPhone, iPad and iPod is more or less the same as above. Go to the settings menu, click on the Wi-Fi icon and slide the switch to the desired position.

How to turn it on or offWi– FiVWindows

In this OS you can also turn wireless networks on and off, but the process is slightly different:

go to the Start menu – Control Panel;

go to the Networking and Sharing center;
in the menu that opens on the left, find the item Change adapter settings;
find your connection, right-click to connect;
do the same to turn off Wi-Fi.

Wi-Fi technology is very widely used in life modern man, because it allows you to easily and quickly solve problems with connecting to the Internet without using conventional wires. This is especially true when using laptops, which can be used to access the Internet in any convenient place thanks to the presence of a built-in Wi-Fi adapter.

That is why the situation when Wi-Fi does not work on a laptop leads to significant inconvenience and even some problems. The reasons why laptop computer Wi-Fi may not work, there are quite a few. It is simply unrealistic to solve the most serious of them on your own without the help of specialists, but there are quite a lot of them that can be eliminated on your own. Let's look at them.

Is the problem with your laptop or router?

A fairly common problem is that the laptop has stopped connecting to WiFi networks, the problem is not with the laptop itself, but with the settings of the router, which distributes the network. Thus, the laptop can be configured correctly, but Wi-Fi still does not turn on precisely because it has nothing to connect to.

To rule out the possibility that the problem is related to this, you should try to connect to the network from any other device that is equipped with a Wi-Fi adapter - from another laptop, smartphone, tablet, etc.

If Wi-Fi does not work from another gadget, then the problem lies in the Wi-Fi router distributing the Internet. If the connection is successful, the problem is in the laptop and before solving it, you first need to determine why Wi-Fi stopped working.

Hardware enable adapter

Based on such diagnostics, it is possible to accurately determine that this problem arose precisely because of the laptop. When Wi-Fi does not work on it, you can try using several methods.

The first one is to check if the wireless adapter on your laptop is enabled. Almost everything modern models have indicator lights work WiFi module and for him hardware enable There is special combinations keys

Typically, a lit indicator indicates that the module is turned on. If the indicator does not light up at all or lights up in red, then Wi-Fi is not working precisely because of the wireless network adapter. It must be turned on.

Most often, such indicators are located directly on the keyboard, side or front panel of the device case. Sometimes they are located on the monitor body or near the touchpad.

To enable the module of such a network, press the key combination Fn and one of the system keys F1-F12. The specific combination depends on the laptop manufacturer. Usually on the desired key the corresponding antenna icon is located. If it is not there, then to turn on Wi-Fi you should try pressing standard for specific model combination:
Fn+F3 for Acer;
Fn+F2 for Asus, Dell or Gigabyte;
Fn+F5 on Fujitsu devices;
Fn+F12 on HP laptops.

After pressing the corresponding keys, we check whether the wireless connection module operation indicator lights up or whether it stops glowing red. After this, you should try to connect to the network again. If this does not help, move on to the next step.

Software enablement

When Wi-Fi stops working and turning it on in hardware doesn’t work positive results, it is also necessary to implement it software activation, which is carried out directly from operating system, under which the laptop runs.

To implement software turning on WiFi that has stopped working on Windows 7, 8 or 10, you need to perform the following sequence of actions:

1. On the notification panel, which is located near the clock, select the network connection status icon;

2. From the list that opens, select “Network and Sharing Center” or “ Network settings» depending on the operating system version;

3. The next step is “Changing adapter parameters.”

Among the list of all existing connections, you need to pay attention to the color of the “Wireless” icon. network connection" If your WiFi does not work and wireless adapter is disabled, the connection icon will not be highlighted. In this case, right-click on its icon, from the opened context menu select the “Enable” item. The color of the connection icon should change.

In this case, the wireless network adapter turns on, all you have to do is find the one you need in the list of available wireless networks and connect to it.

If after such Wi-Fi action which has stopped working continues to be inactive, you need to move on to the next method of solving the problem.

Driver installation and update

Quite often, the wireless Wi-Fi connection does not turn on due to the lack of a driver or when it is very outdated. To determine availability installed driver, you need to select “Properties” from the context menu of the “My Computer” icon, which is located on the desktop or in the “Start” menu. Next, in the window that opens, select the “Device Manager” command from the menu on the left.

In the new window that opens with a list of connected devices, you need to find the name of the laptop’s wireless network adapter. Usually its name is “Wireless network adapter" or " Wireless Network Adapter", along with which the device manufacturer must be indicated: Realtek, Atheros, Qualcomm or something else.

Having found the desired item and right-clicking on it, select “Properties” from the context menu. In the window that opens, there should be an item “Device is working normally.” But even if there is a mark indicating the normal operation of the device, this is far from a guarantee that it is installed correct version drivers and Wi-Fi turn on correctly. To check it, in the properties window wireless device go to the “Driver” tab and pay attention to the “Development date” and “Supplier” items.

In the event that the supplier is Microsoft or the date of development of the program is several years behind the current one, go to the official website of the laptop manufacturer and download the latest official version drivers.

The same must be done if among the list installed devices There was no wireless adapter.

If in the list of devices the module wireless communication present but marked in yellow exclamation mark, this means that the device is disconnected, as a result of which the network stopped working. In this case, opening the device properties window, you need to click the “Engage” button.

Another reason why Wi-Fi stopped working on a laptop may be that the energy-saving mode is enabled, which prevents the wireless connection from working. To disable it, you need to do the following:
1. Open Control Panel;
2. Select the “Power Options” icon;

3. In the window that opens, select the “High Performance” or “Balanced” mode.

External obstacles to the signal

It's also worth noting that a broken wireless network can also be the result of more than just laptop problems. The wireless signal depends on some external factors which may weaken it. Ceilings, walls, floors and similar obstacles significantly degrade the signal quality of the access point and laptop.

As is known, the signal quality is personal computer is displayed in the form of several marks - the more there are, the higher the quality of the signal. If the wireless connection level is displayed as 1 or 2 marks, then you don’t have to try to use WiFi - in this case it will not work normally.

In this case, you need to move the router closer to your workplace, move workplace closer to Wi-Fi router or buy a new, more powerful router.

If all else fails

If none of the tips given above helped, you can use a simple, but at the same time often effective solution: Restart both the computer and wireless router. Please note that after a reboot, the router turns on for up to 5-10 minutes before it starts distributing the network. Be patient. Also, despite the opinion of many skeptics, sometimes the problem diagnostic function found in the Windows operating system helps solve problems with a wireless network.

Thus, most of the above have been listed existing solutions problems related to the fact that Wi-Fi stopped working on the laptop. Almost all such methods and recommendations can be used by anyone who is faced with a similar problem, since this does not require any special skills.
If nothing helps, and the wireless network does not start working, there is only one option left - go for help to a quality service center, where they can solve any problems with the laptop.

If the article did not help solve your problem and Wi-Fi still does not work, write in the comments, I will try to help.

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

Problems with connection

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

Incorrect operation of the router.
Wi-Fi settings errors.
Availability third party programs installed on the device.
Wrong set parameters phone.

Correct diagnosis will help solve the problem. In most cases, you can do this yourself, without the help of specialists. Slow work Internet connection, for example, may indicate that the network is overloaded because 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. Check correct operation can be done through the router menu, which can be accessed through a browser. To do this, you need to know the username and password, which are either written on the router itself, or, if they have already been changed, you need to find out yourself or reset the settings. Once access to the menu is gained, you need to find out the parameters wireless mode, such as:

Channel width (settable from 5 to 40 MHz).
Channel selection (automatically configured, but you can select it yourself).
Baud rate (set to 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 Wi-Fi on the phone turn off? We need to move on to the next point.

Incorrect operation of the router

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

Indicators will tell the user whether the operation is correct. There are usually three or four of them, depending on the model, and they should all be lit or flashing:

Nutrition. On different models Color may vary (green, blue, but not red). But it should always be on and not blinking.
The system indicator must be blinking.
The WAN indicator is an indicator of the presence of an Internet network.
WLAN indicator - 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 that can be used to restart the device. This trick helps many people.

Availability 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 periodically turns off. Why does this happen and how to avoid it? If you suspect that the device has been subjected to virus attack, it is recommended to install one of the many antivirus programs and run the scan. The program itself will find viruses known to it and eliminate them.

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

Incorrect phone settings

If your device has an unlicensed or broken software, then you shouldn’t be surprised that Wi-Fi turns off. For some reason, this problem happens least often on Samsung phones. Perhaps because the manufacturer fully provides the 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 arise extremely rarely, since it is not subject to third-party influence. But in this case, the user will lose all his data, so important information should be saved before resetting.

Problems with Wi-Fi connections can often be resolved on your own. But physical intervention and repairs can permanently damage the device. If available methods If you couldn’t determine why Wi-Fi turns off on your phone, you should contact technical support centers.

Owners mobile phones and tablets may encounter a situation where, without any action on their part, the wireless access in Internet. If Wi-Fi on Android is turned on by itself, this may lead to fast discharge phone. However, many users do not want to constantly see a notification that no Wi-Fi networks were found. To solve such a problem, its causes must be identified. We recommend setting up Wi-Fi settings on Android in such a way that it is active only when needed by the user of the mobile device. For example, you can configure settings that will automatically search for access points in set time. It is worth noting that the reasons spontaneous switching on there may be several - from settings of gadget parameters to malfunctions of Android. In some cases, the error may occur in certain models phones. In any case, it requires elimination, only then will the operation of the mobile device be stable and smooth.

If the wireless network on the device activates on its own, then you need to look for the reasons for these actions

Solutions to the problem

If Wi-Fi turns on automatically, you can check the status of the power saving mode. If it is active, then the wireless connection on Android can be turned on and off without owner intervention, so try deactivating the mode and observe how the smartphone or tablet “behaves”. If this doesn't help and Wi-Fi keeps turning on by itself, try turning it off and on again. mobile device. Sometimes this helps solve the problem.

It is necessary to understand that the module wireless connection access to the Internet is activated by commands certain programs, that is, the applications themselves can activate it. It is necessary to analyze at what point the problem began to occur on your Android gadget. similar problem. You may have installed an application that automatically launches the wireless module. In this case, we recommend uninstalling it. Unfortunately, not all programs found in Google store Play are safe for smartphones and tablets.

You can install a high-quality and effective antivirus and scan the operating system. If this also does not help, then you should do hard reboot, that is, restoring the phone or tablet to factory settings. There are several ways to do Hard Reset- through Recovery mode, Android settings or the use of operating system service codes. Before doing this, we recommend saving only contacts and media files. Other information may include program code, which causes the wireless access to be constantly activated.

If the described methods did not help and Wi-Fi constantly turns on by itself, then it is better to contact a service center, where qualified specialists will determine the exact cause of this error. It is advisable to find a certified service that repairs phones and tablets of your brand.

Wi-Fi management app

In the shop Google Play can be found and installed for free Smart app WiFi Toggle. It will allow you to set up wireless Internet access. The bottom line is that the program remembers access points and automatically activates them at a convenient time. When the user leaves the access point, Mobile Internet is enabled provided that the user has specified such parameters. You can set up home and work access points. Undoubtedly, Smart WiFi Toggler turns off the wireless connection when the mobile device is out of range of configured access points. You can also configure auto-connection and set individual parameters that will ensure longer battery life.

The problem where Wi-Fi on Android turns on by itself is quite common. It can be solved by uninstalling some applications, installing an antivirus on your mobile device, or returning the gadget to factory settings. In addition to solving the main problem, such actions can fix many other errors and free up memory. As a result, the autonomy of a smartphone or tablet based on the Android operating system will improve.
