Not available on Android automatic switching on Wi-Fi module when an access point is detected and turns off when there is no signal. This has an adverse effect on time battery life device, since an always-on module consumes energy. This problem can be solved special application smart wifi toggler. It detects whether Wi-Fi networks are available and disables or enables the wireless module.
Working with Smart Wi-Fi Toggler is very simple. Install the application from Google Play and launch it. On the pages quick setup specify the desired parameters: after what time after the loss of the signal the Wi-Fi module will turn off, for how long it will turn on to try to connect to a known or unknown point, and also whether the application needs to be launched when the OS starts and whether it can work in background. These settings can be left as is, and in the future any parameters can be changed in the settings. There, the interface language switches to Russian.
Application for correct operation you will need to determine the location of the smartphone. It is not necessary to turn on GPS, the economy mode is enough - via Wi-Fi and cellular networks. This option is available in system settings Android.
Now go to home page Smart Wi-Fi Toggler and start the service. From now on, the application will remember where the Wi-Fi points, and turn off the Internet module when you move away from this place.
IN Smart settings Wi-Fi Toggler shows all saved Wi-Fi networks. You can specify whether the application should automatically connect to and disconnect from them. Here you can increase the accuracy of your work by giving the application access to barometer data. In addition, you can enable an aggressive saving mode, which stops using Wi-Fi when the device's screen is turned off.
Wi-Fi is a technology that allows electronic devices transfer data or connect to the Internet via a wireless network. Nowadays, using Wi-Fi is becoming very common and we can see this technology being used wide range 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 prevents unauthorized access to the network. If you do not have sufficient knowledge to set up your 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 encounter a problem Wi-Fi shutdown 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 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 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'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 level battery charge. Such Wi-Fi features 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 network – 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 may solve Wi-Fi problem when the Internet network on the phone disappears. Go to Settings - Wi-Fi and turn on Wi-Fi. If this famous network, you will have to “forget” it and then connect it again. When you see the password entry window, click on Extra 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 need to take the device to service center to fix the problem.
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, please note specialized applications because in 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.
Developers operating system Android constantly releases updates that users can easily install on their smartphone or tablet. One of latest updates is OS version 4.3. But after the update, users noticed that new Android The Wi-Fi adapter is always on.
Why do you need a constantly working Wi-Fi module?
Don't be afraid. This new feature. But if Wi-Fi is always on on Android, then your battery life has decreased. Moreover, now you cannot even manually completely disable the module. Why is this necessary?
It’s worth noting right away that the module does not work at full capacity. In this mode, it consumes less energy, but is still able to constantly search for a network. If there is a point available for connection, it connects to it automatically.
This function is needed in order to more accurately determine your location. This means that apps like Maps and the like will constantly be running in the background, which in turn will also affect battery life. Not only does Wi-Fi work while sleeping Android mode, but also some applications are constantly active.
How will this affect the battery?
The question of autonomy is quite logical in in this case. But on this moment no reasoned conclusions can be drawn. One can only hope that Google company optimizes specified function and will do moderate consumption energy.
Of course, if you consider such an innovation unnecessary and unnecessary, then this function can be disabled. This will not only reduce battery consumption, but will also slightly speed up the operation of the smartphone itself, since it will free up RAM and the data processing load on the processor will be reduced.
So, how to disable a constantly running wireless module?

Disable location pinpointing
You probably already realized that in the usual way Wi-Fi does not turn off on Android 4.3.
To completely disable permanently active mode detection available networks, you need to go to the device settings.
Then go to Wi-Fi settings. Here you need to find the “Additional functions” item.
Now all that remains is to find the “Always search for networks” section and uncheck this line. Of course, if you need to turn it back on this function, then follow these steps and check the appropriate box. Thanks to this, users can decide for themselves whether to use such features or not.

I've been using Android for several years now, but it still never ceases to amaze me. Today I will tell you about several well-known and not so well-known features and ways to overcome them.
1. The most famous oddity of Android is, of course, the spontaneous launch of applications. Why the developers did this, I don’t know, but the fact remains: Android starts working spontaneously own programs, even if you never use them. By the way, this “never use” is also separate moment. Delete pre-installed applications it is impossible, and a “clean” system is difficult to find, it is rarely released, and at the same time, the quality of the hardware itself may leave much to be desired. Therefore, you have to put up with a dozen applications that are completely unnecessary for you.
The only solution I know of is to disable unused programs. physical memory This will not free up, but it will unload the RAM and reduce battery consumption. And, of course, a degree of irritation. This is easy to do: “settings” - “applications” - select the one you need (or rather, not the one you need) - “disable”.
2. In Lately It has become fashionable to add a mobile module to tablets. Insert a SIM card and you have ready internet without having to search for WiFi or connect via Bluetooth to your phone. But not everyone needs the Internet “here and now,” so the SIM card slot may be empty. And in this case, a situation that is not entirely obvious to the average person arises: mobile module We don't use it, but it continues to work, eating up a few percent of the battery.
This can be solved simply by turning on the “Flight” mode.
3. The biggest bewilderment arose when I discovered that 4% of the battery was consumed when it was turned off (!) WiFi module. Those. it is turned off, but continues to consume energy.
After poking around in the settings, I found most interesting function: "Allow location services and others Google apps search for networks even if the WiFi module is turned off". By default, this function is enabled. I cannot understand why it is needed in principle, how applications search for networks and what they will do if something suitable is found. Unfortunately, I don’t have free Wi-Fi right now, maybe I’ll google how something.
To get to the settings, you need to do the following: in the system settings, look for WiFi -> in context menu select "Additional functions".
p.s. This problem, specific to individual devices. In particular, having found it on my tablet, I did not find anything similar on my phone.
In general, implementing all of the above measures will give the device about 10% battery charge. And this is quite a lot - about 2 additional hours a day. So use it, I hope it will be useful to someone.
