Wi-Fi is a technology that allows electronic devices transfer data or connect to the Internet via a wireless network. 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 prevents 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 wifi router and does not see the network until restarting Wi-Fi on mobile device. 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 obstacles for WiFi signal create 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 the congestion problem Wi-Fi networks.
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's settings and find a setting called "Channel" or "Wireless Channel". From the drop-down menu, you need to select desired number channel.
Most manufacturers resort to various methods to increase battery life. Users Android smartphones are forced to enable such energy 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 Advanced — Wi-Fi in sleep mode do not select "Don't 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 Wi-Fi password and connect the network.
Reset to factory settings
If none of these methods help, try 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 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 WiFi connection. In addition, pay attention to specialized applications, since the store Google Play There are many applications, 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.
In order to save energy resources, the Android operating system turns off the device's battery in standby (sleep) mode. wireless connection via Wi-Fi, that is, it goes into sleep mode. Many users don’t like this, because they want to always be online and respond to new messages and notifications in instant messengers and mail clients. Let's look at how to get rid of constant turn off Wi-Fi on tablets and smartphones with Android.
What is the function needed for?
Due to the widespread use of outdated lithium-ion batteries, gadgets powered by them quickly discharge. Developers of operating systems and applications try to optimize software as much as possible to reduce battery consumption. Thus, the OS and many programs contain functions that, disabling them, will reduce the load on the smartphone. One of them is Wi-Fi in sleep mode, which means deactivating the wireless module.
By default the option is enabled. This is the reason why Wi-Fi on the phone turns off.
Why does Wi-Fi turn off onAndroid? Watch the following video:
Solving the problem
Automatic deactivation of the module is carried out through the system settings:
- Open them on your mobile device and go to the subsection with wireless networks.
- Click on the item of interest, as in the screenshot below.
- Tap on the gear icon in the left corner of the window.
- We get into the settings of the wireless module, where you need to select the “Wi-Fi in sleep mode” item.
- Move the switch to the desired position and exit the device configuration parameters.
Keep in mind that in this case, traffic may be redirected through the mobile Internet, which will incur additional financial costs or wastage of traffic. Take care of the normal connection status (3G). It is better to turn it off before using Wi-Fi.
For 4.4 and later
IN Android versions newer than 4.4 the algorithm looks a little different due to the new interface. In them wireless module in sleep mode it will search for access points, which means that power consumption will increase even in the absence of active connections to the Internet on the user’s part (no downloads, instant messengers are closed).
- Opening configuration parameters wireless networks and go to the desired section.
- At the bottom, tap on the “Additional options” item.
- Click on a familiar item.
- Specify the desired value and close all windows. You can choose to always or never turn off Wi-Fi during sleep mode.
An overview of useful settings on Android that you should know about in the following video:
LBE Security
A number of applications will also help solve the problem, among which we chose LBE Security.
- Install the program and go to the “Battery” section located in the main menu.
Depending on the application version and operating system The list of options may vary.
So, let's conclude. What to choose when setting up Wi-Fi in sleep mode? If you cannot charge your phone during the day, then it is better to enable the option. Of course, provided that there is no risk of missing an important message from instant messengers. In other situations, sleep mode can be disabled.

Hello! I have an iPhone 6s on iOS 10.3.2. After entering standby mode, Wi-Fi turns off after 3-5 minutes and goes into mobile internet. When you exit sleep mode, Wi-Fi turns on after 2-3 seconds. Tell me how to fix this situation?
In fact, Wi-Fi in standby mode does not turn off, but goes into a low-power standby mode. Disconnection from Wi-Fi may be caused by settings or features of the router. Some routers automatically disconnect consumers that do not request or forward packets over the network.
What can you do
1. First check iPhone work in any other place with Wi-Fi (at work, at a neighbor’s). The main thing is that the router is different. Most likely there won't be a problem there. You can even turn off your mobile Internet during the check.
Wait for the phone to “fall asleep” and try sending messages to it via instant messengers for which notifications are configured in iOS ( Settings - Notifications).
2. The next step is to check the iPhone's connection to the router. We show you how to monitor connected devices to the network.
From a computer or other smartphone, see if the connection with the iPhone is lost after it goes into sleep mode.
3. If you find that your iPhone “falls off” from the network in standby mode, you need to tinker with the router settings.
- Look for the setting first IP address lease time. Increase the value of the variable to several weeks or even a month.
- Sometimes it helps to turn off the device EAP encryption. Try turning it off.
- You can try
Hello! I know many cases when in Windows 7, after waking up from sleep mode, the Internet on the computer disappeared. Internet, which was connected via Wi-Fi. He either completely switched off or was . In Windows 10, after the laptop wakes up from sleep mode, you can also see , and the Internet via Wi-Fi will not work. You will need to restart the laptop or try to connect to the network again. In any case, the thing is very unpleasant and will definitely be annoying.
This happens because, to save money, the system disables the Wi-Fi adapter. And after turning it on, it can no longer work normally, which is why the Internet disappears. This problem very often only occurs when running on battery power. Many similar problems happen after waking up from sleep mode: the sound, the keyboard, or the screen in general does not work. But our Internet doesn’t work here, this is much more serious :)
Internet in Windows 10 "Limited" after resuming from sleep mode
All you need to do is prevent the “ten” from turning off the wireless network adapter. To do this, you need to go to the control panel through the start menu.
Select item Devices.
Next we open device Manager, look for a tab in it Network adapters , right-click on your wireless adapter (usually the word Wireless is there), and select the item Properties.
In the new window, go to the tab Power management, and uncheck the box Allow this device to turn off to save power. Click ok.
After these steps, be sure to uncheck the second adapter “Realtek PCIE FE Controller” in the same way (it may be called differently in your case). This is an adapter network card. Judging by the comments, this solution helped a lot of people.
After these steps, the problem with Wi-Fi in Windows 10 after the laptop exits and sleep mode should disappear.
You can also try setting the maximum performance for the wireless adapter in the power settings. If anything happens, I’ll add this information to the article.
Write in the comments about the results, ask questions.
Hello, dear friends. Artyom is with you.
Today we’ll talk about Wi-Fi on mobile gadgets running the operating system Android systems, and specifically about the battery discharge by the Wi-Fi module of your device.
First problem and option-
Connecting to a Wi-Fi network can work even when the smartphone is locked and in sleep mode.
This was done so that the smartphone background I was looking for accessible and public Wi-Fi networks for some services to work. For example, a file may continue to download when the smartphone is locked for a long time.
If you don't need this mode, you can turn it off in the advanced Wi-Fi settings.
Second problem and option - “Always search for Wi-FI networks”.
It may be called a little differently, depending on the shell installed on the mobile device. However, the meaning will be the same.
Even when the Wi-Fi module is physically turned off (in the notification shade), scanning networks can continue in the background. This feature is used for geolocation services.
Satellites will be found faster, and navigation can be more accurate, even when Wi-Fi is not active. Again, the option is disabled in the advanced Wi-Fi settings.
For example, on Huawei devices this option is called "Search Settings".
And on ASUS "Always look for networks".
Usually this does not have a significant effect on battery drain. If you don't think you need these options, you can safely turn them off. At the same time, to the correct Wi-Fi work or the GPS module, this will not affect it in any way.
P.S. A graph of battery discharge and services that discharge it can be found in Android settings(usually this option is located in the battery section).
That's all for now :)
