Wi-Fi is a technology that allows electronic devices to transmit data or connect to the Internet over 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, 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 secure 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. It is enough just to fill out the form at http://kompom.kiev.ua/ and the setting will be done quickly and efficiently.
Another problem: Wi-Fi is intermittently lost. Usually, in the absence of activity, the phone or tablet loses its connection with the wifi router and does not see the network until the Wi-Fi is restarted on the mobile device. There can be several reasons why the connection to Wi-Fi is lost, in this article we will consider several options for solving the problem when Android loses the Wi-Fi network.
If you are faced with the problem of turning off Wi-Fi on your Android device, try the following settings and you can connect your device wirelessly without much hassle.
Wi-Fi network overflow
The greatest interference to a Wi-Fi signal is from nearby wireless networks. The problem is that most Wi-Fi devices operate in the already occupied 2.4 GHz band, and high signal density can interfere with each other, reducing the speed and performance of networks.
Solution: Use a dual band router that can operate both 2.4GHz and 5GHz at the same time. The 2.4 GHz 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 range. If your router can operate in the 5GHz band, use it to solve the Wi-Fi 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: If channels 1, 6 and 11 are used, there will be no interfering overlap as 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 the desired channel number.
Most manufacturers use a variety of methods to maximize battery life. Android smartphone users are forced to enable such power saving features in their devices. One such feature is to turn off Wi-Fi when the phone is inactive or when the device has a low battery. These features of Wi-Fi in sleep mode create problems connecting to the network as needed.
Solution: Just adjust the settings of your Android device and make sure you always have Wi-Fi turned on, even when the 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 the Settings menu - Wireless networks- Wi-Fi and select Advanced - Wi-Fi in sleep mode do not select "Do not turn off".
On those devices that run on Android 4.0 ICS and higher, go to Settings - Wi-Fi, select Advanced and set the Wi-Fi during sleep option - "Always".
Change DNS servers
Changing the DNS servers can solve the Wi-Fi problem when the internet connection on the phone is lost. Go to Settings - Wi-Fi and turn on Wi-Fi. If it is a known network, you will 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 fields. Now enter the Wi-Fi password and connect the network.
Factory reset
If none of these methods work, perform a hard reset on your Android device. If after doing this you have problems when your Wi-Fi connection is lost, then it might be a hardware issue. You may need to take your device to a service center to fix the problem.
We've covered the most common causes of Wi-Fi disconnection that happen on Android devices. We hope this will help in solving the problem and will allow you to set up a stable Wi-Fi connection. Also, pay attention to specialized applications, as there are many applications in the Google Play store, using which will help ensure a reliable connection. Some of them are Wi-Fi Fixer, Fix My Wi-Fi, Wi-Fi Analyzer and others.
Hey! I know of many cases when in Windows 7, after waking up from sleep mode, the Internet on the computer disappeared. Internet that 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 that the Internet via Wi-Fi will not work. You will need to restart the laptop, or try to reconnect to the network. In any case, the thing is very unpleasant and will definitely be annoying.
This is because to save money, the system turns off the Wi-Fi adapter. And after turning it on, it can no longer work normally, and therefore the Internet disappears. This problem very often only occurs when running on battery power. Many similar problems occur after exiting sleep mode: the sound does not work, the keyboard, or the screen in general. And here the Internet does not work for us, this is much more serious 🙂
Internet in Windows 10 "Restricted" after waking up from hibernation
All you need to do is prevent the top ten from disabling the wireless network adapter. To do this, you need to go to the control panel through the start menu.
Select item Devices.
Then we open Device Manager, we are looking 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 energy... Click on ok.
After these steps, be sure to uncheck the second adapter "Realtek PCIE FE Controller" in the same way (you may call it differently). This is a network card adapter. Judging by the comments, this solution helped a lot.
After these steps, the problem with Wi-Fi in Windows 10 after the laptop exits and hibernation should disappear.
You can also try to set the maximum performance for the wireless adapter in the power settings. If anything, I will supplement the article with this information.
Write in the comments about the results, ask questions.
Surely many active Internet users through a wireless connection noted the feature of smartphones.
It consists in turning off the wi-fi connection when going into sleep mode. In most cases, this can be associated with the energy-saving mode, which leads to the disabling of wi-fi on Lenovo.
Wireless configuration rules
The situation can be changed by changing the settings. To do this, you need to go to the Wi-Fi settings control mode.
In this case, a list of networks available for connection will appear for the user. You need to use the Menu button. Most often, it is the first one on your device. Next, you select the Additional functions section, where the main interest is how to set up sleep mode on Android.
Select the appropriate item. When you click on it, a series of actions will appear that you can perform when this condition occurs. Accordingly, you will be interested in the actions of the wi-fi when the smartphone falls asleep.
You need to check the box next to Always On or Intelligently. After that, you can exit with saving the settings. It is necessary to understand that the included wi-fi on Lenovo will reduce the operating time of the device due to high power consumption, but you will always be in touch.
If on your Android system hibernation still disables the Wi-Fi module, then you can use other methods.
For this, there are special applications that allow you to change system settings. The most common is LBE Security.
How to set up the LBE Security program
The program can be downloaded from the Play Market or from w3bsit3-dns.com -.
To use the application and configure the module to work in sleep mode, you need to go to the Battery section. In some cases, you may note that the Profile by Event function is checked in the presets.
It is in it that the disabling of wi-fi can be explicitly set when the screen is turned off or the operating profile of the device is changed.
If you want wi-fi to always work, regardless of the state of the smartphone, you must remove this parameter.
It is important to note that different devices may have different presets, so each situation is individual and requires rechecking of all parameters.
Some programs cannot work in full mode when wi-fi is turned off. Moreover, it turns off not because of a bad signal, but because the tablet goes into sleep mode. This is enough for the wireless connection to be interrupted, the music stops playing, and you do not receive messages from ICQ. In appearance, this process does not conceal anything annoying, but when you are faced with a problem at the user level, and not an outside observer, you learn dozens of nuances.
How do I prevent wi-fi from turning off on my tablet in sleep mode?
Sleep-depriving Tablet PC? A discharged battery will cause much more inconvenience. Install a special utility that will prevent the screen from turning off? But the network access indicator also blinks, as if wi-fi is available. You should not resort to installing additional software if you can configure continuous access to wi-fi using the resources of the tablet itself. This is not difficult to do. It is enough to go into the settings and change some parameters.
Wi-fi does not "fall asleep"!
For earlier versions of Android OS, such an algorithm is useful. First go to "Settings". Find the item "Wireless networks" in the menu. Select "Wi-Fi" from the list provided. In the same menu, click on "Additional wi-fi settings" and select "Never" in the options for disabling wi-fi.
If you are dealing with Android 3.0 and earlier, the "Advanced Settings" item also opens in the "Wi-Fi" section. In the upper right corner of the screen you will see a button with three dots, click on it. Select the command line "Leave Wi-Fi on sleep mode", in the drop-down menu, check the item "Never". Or set a time period that meets your needs and system needs.
If you want to install programs that will control the wi-fi connection, you can use Wifinostandby or another program. After installation, restart your tablet and activate the program.
The Android operating system, in order to save energy resources of the device's battery in standby (sleep) mode, turns off the wireless connection via Wi-Fi, that is, goes into sleep mode. Many users do not like this, because they want to always be online and respond in time to new messages and notifications in instant messengers and email clients. Let's take a look at how to get rid of constantly turning off Wi-Fi on Android tablets and smartphones.
What is the function needed for?
Due to the widespread use of outdated lithium-ion batteries, gadgets powered by them drain quickly. Developers of operating systems and applications are trying to optimize software as much as possible to reduce battery consumption. Thus, the OS and many programs have functions that can be disabled to reduce the load on the smartphone. One of them is Wi-Fi in sleep mode, which means deactivating the wireless module.
The option is enabled by default. This is the reason that the Wi-Fi is turned off on the phone.
Why does Wi-Fi turn off onAndroid? Watch the following video:
Solution
Automatic deactivation of the module is carried out through the system settings:
- We open them on our 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 can be redirected through the mobile Internet, which will bring additional financial costs or wasted traffic. Take care of your normal connection (3G). It is best to turn it off before using Wi-Fi.
For 4.4 and newer
In Android versions newer than 4.4, the algorithm looks a little different due to the new interface. In them, the wireless module in sleep mode will search for access points, which means that power consumption will increase even in the absence of active Internet connections from the user's side (no downloads, messengers are closed).
- Open the configuration parameters of wireless networks and go to the desired section.
- At the bottom, tap on the item "Additional options".
- We click on a familiar item.
- Specify the desired value and close all windows. You can choose to turn off the Wi-Fi module in sleep mode always or never.
An overview of useful settings on Android that you should know about in the following video:
LBE Security
A number of applications will help to solve the problem, among which we have chosen LBE Security.
- Install the program and go to the "Battery" section located in the main menu.
The list of options may differ depending on the version of the application and the operating system.
So, let's draw a conclusion. What to choose in setting Wi-Fi in sleep mode? If during the day it is not possible to charge the phone, 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.
