There are times when Wi-Fi on the phone periodically turns off. The problem can be caused by various reasons, including viruses, inappropriate applications, incorrect router settings, etc.
At the very beginning, you need to carry out diagnostics and determine why the access point on the phone is disabled.
Then you can start solving the problem. More information about the most popular causes, as well as methods for eliminating them, will be discussed in this article.
Common causes and solutions
From the information described below, you will find out why Wi-Fi on an Android phone turns off by itself. You will also be able to familiarize yourself with troubleshooting methods.
Failure in work
If the device is running, cache full errors will accumulate.
The device may also overheat, which negatively affects its operation.
The following instructions will help correct the situation:
- Press and hold the device's power button. Select reboot option.
- Unplug your router for a quarter of an hour. Then turn it on.
After completing these steps, the Internet should work.
It is also recommended to monitor at what interval the wireless network is disconnected, as well as the circumstances.
For example, if several devices are connected, or after some time due to overheating.
Availability of third-party applications
Why does Wi-Fi disappear on my phone?
Some applications installed on your phone may block the wireless network.
This applies to antiviruses, assistants for wireless network configuration, or for monitoring speed.
Often problems are caused by applications that require a lot of access to phone functions. Complete removal of the software will be required.
Problems can also be caused by low-quality applications. Basically, if they were downloaded not from the official store, but from third-party sites. When you install jailbroken apps, you risk compromising the security of your entire device. It will stop working correctly.
To solve the problem, you will need to remove all applications that do not have a license. You also need to reset all phone settings to factory settings.
Check your router configuration
Why does Wi-Fi turn off on my phone? If the access point parameters are set incorrectly on the router, failures may occur. These include:
- weak signal;
- wireless network bandwidth overload;
- enabling data transfer through an unstable VPN.
Place yourself and your phone close to the router and change the channel width.
Then disable the VPN function.
There is a high probability that you will need to move the router to another location. Often it is necessary to purchase a more powerful analogue, or use a signal repeater.
If you want to fully determine the faults of the router, then connect to another point. If the Internet works without interruptions, there is a high probability that problems are present only in your home Wi-Fi. In this case, replacement of all equipment is required.

What does Wi-Fi turn on automatically?
First of all, it leads to an accelerated discharge of the phone’s battery, which is very annoying, but not so scary until it turns out that Wi-Fi itself is turned on by a virus. It’s good if it’s not a dangerous adware virus and will pester you with all sorts of new products. Much worse are ransomware viruses and those that steal from your phone.
Other reasons
If Wi-Fi on your phone fails, there may be other problems.
Among them are:
- Enable energy saving mode. You can disable it in the battery settings.
- Enable the router restart function at a certain time. Often restarts are carried out at intervals of 30, 50 and 80 minutes. This feature must be disabled.
- Poor quality update of the official firmware. Updating the system will help correct the situation. You can also return it to its original condition.
The value of a small amount of traffic
Why does wifi turn off on my phone?
If you use mobile Internet, it is very important to monitor the amount of traffic.
Operators, when connecting to the service, provide a certain amount of traffic (you can find it out in the operator’s application).
Once you use this amount of data, your speed will drop. You can purchase additional gigabytes for an additional fee. Often, notifications from the operator come for this. You can also install special applications that will monitor traffic.
If a notification about a low amount of traffic does not come in an SMS message, but in the phone curtain, then you set it up yourself. If necessary, disable the function in your phone settings.
Disable power saving.
If the Wi-Fi hotspot keeps turning off on your Android device despite disabling (or changing) the timeout settings, make sure you haven't turned on the power saving mode. Battery Saver Mode, when enabled, may temporarily limit the operation of some applications to extend your device's battery life. If your Android hotspot keeps disconnecting, turn off power saving and try again.
Step 1: Launch Settings and select Battery.
Step 2: Then select Battery Saver.
Step 3: Click the "Quit" button.
You can also turn off power saving in your device's notification panel. Swipe down from the top edge of your smartphone display, find and tap the battery icon to turn off power saving.
If the mobile Internet does not work
The most difficult thing is to determine why the mobile Internet does not work and the phone itself disconnects from wifi. After all, the factors can be completely different:
- Low communication signal for data transmission.
- Expiration of the service package from the mobile network operator. This often happens when the money on your balance runs out and there is no way to extend access.
- Technical problems that occurred on the operator’s side.
- Launching Flight mode on your phone. After all, it disables the possibility of any communication.
- Disable data transfer to devices. You can correct the situation in the settings.
- Problems with the operation of any program that is used to use the Internet. These could be browsers, social networks or instant messengers.
- Connection problems if you are using a VPN.
- Lack of correct access point settings.
- Problems with the operating system itself. This also applies to the presence of viruses.
- Incorrect settings in the menu due to which the data transmission frequency is disabled.
- The phone is tied to another operator.
- SIM card malfunction.
- Problems with the operation of the module to which the SIM card is connected.
As you can see, there can be a large number of reasons why Wi-Fi constantly connects and disconnects. Some of them are simple, others are complex. If you cannot cope with any error yourself, you can use the services of consultants in your operator’s stores.
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's settings and find a setting called "Channel" or "Wireless Channel". From the drop-down menu, you need to select the desired channel number.
Limited traffic on Android
Very often traffic is consumed quickly and in large quantities through no fault of the user. The blame lies with some apps. They often work in the background, so they are constantly transferring and sending data.
You can find them using standard tools installed on the operating system. Searches are carried out using the following algorithm:
- Go to your device settings. Find the “Data Transfer” function.
- Select "Mobile Data Transfer".
The screen will immediately display information about the general schedule of mobile Internet traffic expenses. Below there will be a rating of applications that consume the most traffic. Click on the application you want and disable running in the background.
Afterwards, the program will not receive or transmit data until you allow it.
The difficulty of the work lies in the fact that first you need to understand what Internet consumption rates each application has.
Browsers, media search services, and online maps often cause the most problems. Applications that work offline do not consume mobile Internet.
If you want to set up warnings, as well as a traffic limit, then follow these instructions:
- Go to the device settings and select “Data transfer”.
- Find the "Payment Cycle" item. It shows when the subscriber will be charged for the provision of services. A new gigabyte package will be provided on the same day. Specify a cycle so that the system knows when traffic is being reset.
- Launch the “Alert Settings” function and select “Warning”.
- Specify at what traffic indicator the system should notify you.
If you want to greatly limit your traffic consumption, then run the “Setting traffic limit” function. Then manually enter the desired value.
Once you reach it, the system will automatically turn off the mobile Internet. Network Restriction is a feature that prevents background programs from running on wireless networks.
Apps will issue warnings before using networks for large downloads. It is better to ignore this nuance, because it can cause problems with your phone.
To set a traffic limit on the Internet, follow these instructions:
- Go to settings, where you will find the “Data transfer” item.
- In the menu that opens, select the desired network. If your phone has multiple SIM cards, you should select two networks.
- Check the box next to “Set a limit” and confirm the actions in the window that appears.
- Set the desired traffic limit. As soon as you notice the orange line, it indicates that you are moving towards the final value. The red line indicates that the Internet is disabled because you have reached the set limit.
Using this method, you can set a traffic limit for 30 days. If you require a limit for every day, you will have to change the date daily. The limit is also set for each day. If you are working, you can set low values. Whether you're on the road or at home, you can increase the traffic size.
There are functions that allow you to manually start saving traffic. To do this, follow this algorithm:
- Go to your phone settings and open Mobile Network. Select "Data transfer".
- Open the Data Application Cycle tab. Specify the period of time during which the restriction will operate.
- Set the desired traffic volume, beyond which you cannot go.
- Check the box next to “Limit mobile traffic”.
If you have Android version 7 or higher installed on your phone, there is an automatic mode that allows you to save mobile traffic. You can run it using the following instructions:
Open the quick settings menu.
- Enable a mode that will save traffic.
Router settings
At the first stage of troubleshooting, you should check the router settings. For this purpose, the user accesses the control panel, which opens in any browser. Each router has its own address for entering the settings. Classically, this is “192.168.1.1”. Login and password can be: “admin”. Otherwise, it is recommended to look at the necessary information on the label of the router box.
What you need to check in the settings:
- is the DHCP server responsible for independently obtaining an IP address working?
The picture shows where you need to check the box:
- what level does the channel have (shaping). This option has an automatic setting;
- whether the channel is selected automatically;
- how data is transferred. To do this, you need to select the maximum of the proposed values;
- region almost never causes problems with the router;
- safety.
As soon as the router has been purchased, it is recommended to start setting up the settings. If installed correctly, you need to turn to another solution to the problem.
If the system shows an authentication error, you should reflash the router, as experienced users suggest. Problems with the network may indicate an outdated firmware version. But it is recommended to entrust this to specialists.
The software is located on the manufacturer's official website. To change the firmware, go to “System Tools”. Next, specify the path to the firmware file and update the system.
Disabling 4G/3G on your phone
On mobile phones with the Android operating system there is a button to turn on and off the mobile Internet. It is located on the quick access panel.
If you move the “Curtain” located at the top of the screen, you can get to it. Just press a button to enable or disable mobile Internet on your smartphone.
As you can see, the Internet on your phone turns off automatically for various reasons. First you need to identify them, and then begin to eliminate them. If you follow the recommendations described in this article, you can quickly fix problems and Wi-Fi will not crash on your phone.
How to Access a Peer-to-Peer or Hidden Network
There are two networks that have limited automatic access: the network you want to connect to is a specific type, or a network that is hidden for security reasons.
Regarding the first problem, most Android smartphones are not configured to work in peer-to-peer networks. However, the good people of the XDA Developers forum have created a patch that allows you to bypass this limitation. With the wpa_supplicant file, you can connect to these types of networks.
Attention: This solution is intended for advanced users only.
If the problem is with a hidden network, you can try adding it manually. Go to Settings > Wi-Fi > Add network. Enter the network SSID and password.
