Wifi android is always on. Why is the Wi-Fi adapter always on on Android?

Wi-Fi is a technology that allows electronic devices to transmit data or connect to the Internet wirelessly. These days, the use of Wi-Fi is becoming very common and we can see this technology being used by a wide range of devices such as smartphones, tablets, gaming 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, then 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 drops out periodically. Usually, when there is no activity, the phone or tablet loses connection with the Wi-Fi router and does not see the network until Wi-Fi on the mobile device is restarted. There may be several reasons why the Wi-Fi connection is lost; in this article we will look at several options for solving the problem when Android loses the Wi-Fi network.

If you are facing the problem of Wi-Fi turning off on your Android device, try the following settings options 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 comes from neighboring wireless networks. The problem is that most Wi-Fi devices operate in the already occupied 2.4 GHz band, and the high density of 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 simultaneously. The 2.4 GHz frequency 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 in this band. If your router can operate in the 5GHz band, use it to solve your Wi-Fi network congestion problem.

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: In the case of channels 1, 6 and 11, there will be no overlap causing interference, since these are not overlapping channels. To work on these channels, users will need to go into the router settings and find a setting called “Channel” or “Wireless Channel”. From the drop-down menu, you need to select the desired channel number.

Most manufacturers resort to various methods to increase battery life. Android smartphone users 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 low battery. Such features of Wi-Fi in sleep mode create problems when connecting to the network as needed.

Solution: Simply configure 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 networks– Wi-Fi and select More – Wi-Fi in sleep mode do not select “Do not turn off”.

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

Change DNS servers

Changing DNS servers can solve the Wi-Fi 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 connect again. When you see the password entry window, click on Additional options and select “Static” from the IP settings in the dropdown menu. Then scroll down and enter the IP address of the DNS server you would like to use in the DNS1 and DNS2 field. Now enter your Wi-Fi password and connect to the network.

Reset to factory settings

If none of these methods work, hard reset your Android device. If you then have problems where you lose your Wi-Fi connection, then it could be a hardware problem. You may have to take the 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 solve the problem and allow you to set up a stable Wi-Fi connection. In addition, pay attention to specialized applications, since there are many applications in the Google Play store, the use of which will help ensure a reliable connection. Some of them are Wi-Fi Fixer, Fix My Wi-Fi, Wi-Fi Analyzer and others.

It turned out that this was not a bug.

Many iPhone and iPad users have noticed that after switching to , Wi-Fi on their devices automatically turns on from time to time. Disabling Wi-Fi in Control Center solves the problem only for a short time, after which the wireless connection becomes active again. As it turns out, this is not an iOS 11 bug.

That's what Apple intended

In the updated Control Center in iOS 11, you cannot completely turn off Wi-Fi and Bluetooth. When you click on the Wi-Fi and Bluetooth icons in Control Center, you disconnect from the connected wireless network and Bluetooth device, respectively. And when the iPhone or iPad finds an already known wireless network, or a network without a password, the device automatically connects to it.

Why did Apple do this? The answer to this question was found in the company documentation. By not disabling Wi-Fi and Bluetooth completely from Control Center, other iPhone and iPad features will continue to work. Other functions include: geolocation services, AirPlay, AirDrop, Handoff, Instant Hotspot and Continuity. In addition, the Apple Watch will not automatically disconnect.

How to completely turn off Wi-Fi and Bluetooth in iOS 11

In order to completely turn off Wi-Fi and Bluetooth in iOS 11, you will have to launch “Settings” and turn the function switches to the inactive position.

The Wi-Fi module in a tablet or phone running the Android operating system is one of the most important components today. Wireless networks surround not only homes, but also at work, in your favorite coffee shops and even on public transport. Wi-Fi on Android usually doesn't turn on at the most inopportune times. Why might this happen? There are several options:

  • the password is entered incorrectly;
  • the network connection or system settings are lost;
  • there was a failure in the operating system;
  • the wrong firmware was installed;
  • The Wi-Fi module itself has failed.

Most often the problem turns out to be in the settings. Of course, if a smartphone falls into water, there is a possibility that something is wrong with the module. But if nothing happened, and the network suddenly disappeared, the error is most likely a software one.

If Wi-Fi on Android does not start, first of all you should:

Often the reason for Wi-Fi not working is very simple. But it doesn’t always involve an incorrect password or the wrong time. If after all the steps the Wi-Fi icon is still gray, it’s time to move on to something more decisive.

Restoring settings

The simplest solutions for restoring Wi-Fi involve setting the correct date and time. If airplane mode is not active and the date and time are correct, you can try resetting the device to factory settings. Having previously saved the data in cloud storage or on another device.

Android users have encountered the problem of forever loading when trying to update or install applications through the Play Market. This also affected the performance of the network. If this is your case, try clearing the Play Market cache and deleting temporary files.

Router settings

Do you go to additional settings and get the error “mac address not available”? Turn off Wi-Fi on the device, as well as the router itself. After some time, connect back and try to access the network again. If this does not help, the encryption settings on the router itself may have been changed. Some Android devices simply do not see encryption channels higher than 11. Change the router settings and connect again.

Android engineering menu settings

If your device is powered by a MediaTek processor (most devices with a Qualcomm processor do not have this option), you can go to the engineering menu and set the Wi-Fi settings directly through it. You can open it using the command “*#*#3646633#*#*” entered in the dial pad. For some tablets that do not have this panel, you can install special utilities to enter engineering mode. The settings are checked and set in the "connection" tab.

You should only configure something through engineering mode if you are an advanced user of the Android platform. This is a mode for developers; any changes at random can lead to unpleasant consequences.

Wi-Fi settings on Android TV-box

The TV Box, which also runs on Android, like smartphones and tablets, is also not without connection problems. To work with it, it is recommended to use an external Wi-Fi adapter or connect a cable, but this will only help improve the speed. And if there is no Wi-Fi connection at all, then it is recommended:

  1. Go to the file manager.
  2. Find the WIFI folder and the wpa_supplicant.conf file in it.
  3. Delete file.
  4. Wait a while and start searching for Wi-Fi on the set-top box.
  5. The device will automatically find a connection.

Didn't help? Time to check the software.

Software glitches

Wi-Fi may not work or randomly turn off due to recently installed applications. Go to the application manager on your mobile device and see which one receives the most activity during the flight. Such an application usually also mercilessly eats up the battery, so the smartphone or tablet “dies” faster. It will be enough to delete the application or install another version with which the error was not observed.

It is recommended to check whether you have any applications that restrict Internet access. So, you can set restrictions through a number of firewalls even without root rights. There are also special utilities for checking software, thanks to which you can see which application is causing the network to generate an error. Additionally, it is recommended to check the device for viruses - some of them may create problems with the network connection via Wi-Fi.

Installing the wrong firmware

The cause of problems with the operation of the Wi-Fi module may be custom firmware that blocks the connection. Manufacturers recommend installing only official firmware versions: custom versions are not always reliable. If problems arise after flashing, you should roll back the device to factory default or flash it again. Only now on the official one.

The Android operating system is the most popular mobile platform in the portable device market. One of the few disadvantages of this OS is the short battery life. One of the reasons why your battery drains quickly is that Wi-Fi turns on constantly on Android. Starting with version 4.3, Google developers gave the GPS module the ability to activate Wi-Fi on its own to improve its performance. In addition, spontaneous turning on of the Internet can occur for other reasons.

Reasons

Devices with the Android mobile platform are often criticized for independently activating modules, updating applications, transferring data and other similar actions. The reasons why Wi-Fi turns on on Android by itself can be very diverse.

First of all, this is the already mentioned function of determining the exact location. GPS information and geolocation data play an important role in the operation of an Android gadget. Inexperienced users often do not even realize that their device is constantly transmitting information about its location, while mercilessly draining the battery.

To understand why Wi-Fi turns on by itself on an Android phone, you need to consider the following aspects of the operation of the mobile device:

  • energy saving mode;
  • presence of viruses on the smartphone;
  • installed third-party applications;
  • damage to the wireless internet module.

As you can see, there can be quite a few reasons for Wi-Fi turning on spontaneously on smartphones running Android OS. Next, we'll take a closer look at why Wi-Fi turns on on Android and how to fix the problem.

Solution

So, everything is more or less clear with the reasons for the spontaneous activation of the module; it’s time to figure out how to solve possible problems.

Disabling Precise Positioning (GPS)

Determining location on Android devices allows you to receive a lot of useful information - the GPS option makes it possible to find out about traffic jams, find the desired address, etc. But for the same reason, Wi-Fi on Android turns on spontaneously. Fortunately, gadgets running Android OS allow you to disable and enable geolocation mode at any time. More detailed recommendations on disabling geolocation can be found in the material “How to disable GPS on Android.”

Enabling Power Saving Mode

To increase the autonomy of your Android smartphone, you can configure automatic switching to power saving mode. And if Wi-Fi on Android turns itself on, it can help save your device's battery. It should be understood that in this state, your device will not be able to provide up-to-date information on navigation on Google maps, and the functions of synchronizing applications, sending geolocation parameters, and data transfer will be very limited. To solve this problem, read the article “How to deactivate power saving mode.”

Scan your device for viruses

While downloading files, transferring data between gadgets, or simply surfing the Internet, viruses can penetrate your smartphone. If your Wi-Fi keeps turning on on Android, it may be the result of a virus infection. Malicious applications can block programs, affect the performance of the device, and force the gadget to independently send various data using a Wi-Fi connection. To deal with the problem of the presence of viruses and remove them from your device, read the article “How to check Android for viruses.”

Uninstalling third-party applications

There are situations when no viruses are detected on the smartphone, all functions that can activate the module are disabled, but Wi-Fi on Android still turns on automatically. The problem may be that one of the installed applications requires a connection to Wi-Fi and does so on its own. Some programs may contain virus modules and transmit personal user data. To fix this situation, you need to go to “Settings”, then the “Applications” menu and select “Third Party” in it. Evaluate the list of installed software and remove applications that you consider suspicious.

Restoring factory settings

If all the tips mentioned did not help and the Wi-Fi module continues to turn on on its own, you can resort to the most radical measures - resetting the settings. It is important to understand that this step will delete all user installations, settings and personal data. However, sometimes it is worth sacrificing information to solve the problem of spontaneous activation of Wi-Fi. Moreover, most personal data and settings can be saved by first making a system backup.

Service center help

Quite often, the situation when Wi-Fi automatically turns on on Android cannot be solved by the user’s efforts, since the reason lies in the hardware. In this case, the only correct solution is to contact a specialized service center for help. Experienced specialists will evaluate the condition of the smartphone’s hardware, including the Wi-Fi module. If it turns out that this is the problem, it will be possible to repair or replace the failed components. As a rule, eliminating such problems does not require large financial investments.

Consequences of spontaneously turning on Wi-Fi

Spontaneous activation of the Wi-Fi module can become a rather serious problem. Due to the fact that the smartphone has free access to the Internet, it can update applications and send various data without the owner’s knowledge. In addition, on low-power devices this leads to a difficult response to user actions and overall system slowdown. The main inconvenience is the rapid consumption of battery power.

Battery problems

The problem of turning on the Wi-Fi module independently on devices running Android OS is very common. The consequences can be quite dire - the battery will discharge very quickly. As a result, you will not be able to use the device when necessary, you will easily miss an important call, a message in the messenger, or the functionality of the device will be reduced until you restore the charge. The tips we provide in this article will help you avoid this.

Wi-Fi adapter is always on on Android: Video

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.

Connection problems

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

  • Incorrect operation of the router.
  • Wi-Fi settings errors.
  • The presence of third-party programs installed on the device.
  • Incorrect phone settings.

Correct diagnosis will help solve the problem. In most cases, you can do this yourself, without the help of specialists. Slow Internet performance, for example, may indicate that the network is overloaded because there are too many devices connected.

Settings errors

The first thing you should pay attention to is the settings of the Wi-Fi access point itself. You can check correct operation through the router menu, which can be accessed through a browser. To do this, you need to know the user's login 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 obtained, you need to find out the wireless mode parameters, 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. Color may vary on different models (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 there are LAN ports, to which a cable for wired Internet is connected. 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 there is a suspicion that the device has been subject to a virus attack, it is recommended to install one of the many anti-virus programs and run a 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 unlicensed or broken software is installed on the device, then you should not 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 by a full reset to the original 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 using available methods it is not possible to determine why Wi-Fi turns off on your phone, you should contact technical support centers.
