Wi-Fi does not turn on on Android Samsung. Wi-Fi not working on Samsung Galaxy? Changing your static IP address

Wireless Internet users periodically have to face problems associated with the inability to use the Internet. There may be several reasons why Wi-Fi does not work on the phone: from trivial errors with entering a password to more global ones - incorrect router settings.

You can also often hear complaints from users that the speed of wireless Internet leaves much to be desired. How to deal with each of these situations and fully use the Internet from your gadget? In this article we will talk in detail about why the phone does not work via Wi-Fi and how to fix possible problems yourself.

Incorrect connection information provided

One of the most common situations related to the inability to use the Internet is an incorrectly entered password in the gadget settings. Modern mobile devices - tablets and smartphones - have a wonderful feature - saving a password. This will help avoid mistakes when entering complex password combinations.

However, such a measure will not be effective if the password for the access point is changed in the router settings. Why did Wi-Fi stop working on my phone if the connection was correct before and the password was saved in the smartphone settings? Most likely, the problem is that the administrator changed the password and did not warn the user about it.

Viruses have entered the operating system of the gadget

Another answer to the question why Wi-Fi does not work on the phone may be the presence of a virus program. People who use gadgets on the Android platform most often have to deal with this problem. It is for such devices that a large number of malware have been created. Specialized “cleaning” programs can help you cope with the virus; you can download them through the Play Market service.

We also draw the attention of users that in order not to encounter a similar problem and not be tormented by the question of why Wi-Fi on the phone does not work well or does not work at all, you should install applications only through the standard market of the operating system.

Error in date and time settings

Incorrect values in the calendar and on the gadget's watch face also cause the wireless access point to become unavailable. A similar situation occurs for personal computers. All the user needs to do is adjust the data. After this, Internet access will be provided as normal.

Router settings

Many of the users who have a router installed do not even suspect that this equipment has quite a lot of different settings, limited to entering the name of the network and setting the degree of protection.

However, they often have to wonder why Wi-Fi does not work on their phone. In such a situation, the access point will be present in the list, but when you try to connect to it, a notification will be issued. How to fix it?

First of all, you need to go to the router settings menu - for each device model there is a personal combination of characters that must be entered into the browser in order to access it. It is recommended to check the user manual for information regarding your specific model. After the router menu opens on the computer display, you need to check the following parameters in the " Wireless Internet settings":

Channel - auto.
Mode - 11 bgnMixed.
MAC Address Filter - disabled.

After correcting the data, if necessary, you should save the setting and restart the device.

Problems with the gadget software

The answer to the question "Why doesn't Wi-Fi work on my phone?" It may also be due to the fact that there are some difficulties in the gadget’s software. Such failures can occur when the operating system is tampered with, for example, non-original firmware is installed.

In this case, it makes sense to use the built-in function to return your smartphone or tablet to factory settings. This feature is present on all modern models. It is worth considering that a number of data will be deleted from the gadget - applications and files. Therefore, it is recommended to first save important information to third-party storage media.

To conduct a test and check whether the problem is really in the software, it is recommended to try connecting to several wireless Internet points.

Reasons for low wireless Internet speed

Why is Wi-Fi on my phone slow? There can also be several reasons for low speed, here are the most common:

Many people use the Internet at the same time. The load on the network causes the speed to drop, and in some situations the signal may periodically disappear altogether.
There is a hardware level limitation. This can be used in public places to normalize the load on the network.
Low data link speed. If the speed of the Internet, which is distributed through the router, is low, then via Wi-Fi, accordingly, you will not be able to fully use the Internet.

If you have chosen a tariff for making calls on favorable terms, but it is expensive to use the Internet, then Wi-Fi can come to the rescue. If you install a router at home to distribute a wireless network, this does not mean that you will be able to easily set up a connection. It is at such moments that the question often arises: why Wi-Fi does not work on the phone. It may be easy to fix this problem.

How to establish a wireless connection

A receiver and transmitter are used to configure the communication channel. In this case, the phone's Wi-Fi module is used as the receiving device, and the transmitter can be an ADSL modem, a device capable of creating an access point or a router that supports signal distribution.
There may be several reasons for the lack of Internet connection:
. Failure of the Wi-Fi module due to poor build quality.
. Mechanical damage.
. Consequences of exposure to liquids.
. Software failures.
. Incorrect settings.
First of all, when connecting through a router, if you are faced with the question of why Wi-Fi does not work on the phone, you need to check the presence of a LAN. To do this, connect a computer or laptop to the router using a cable, and if there is no connection, then you need to contact the operator or check the balance.
If there is a connection to the network, then you need to activate or configure Wi-Fi distribution. The documentation included with the router will help you cope with this task. In particular, the service agreement describes in detail how it is possible to activate the distribution, or specifies the Wi-Fi password, without which the connection will not work.
If connection problems occur while trying to connect to a public network, then you need to configure Wi-Fi on your device.

How to set up Wi-Fi on a phone running Android OS

First of all, make sure that Wi-Fi on your phone is active. The “Wireless networks” item displays a complete list of available networks. Find the one you need among them (the wireless network identifier can be found in the service contract, and data on connecting to a public network is often posted in plain view of the organization’s visitors).
If the connection is active, but you cannot understand why Wi-Fi does not work on the phone, then you need to go to the settings. Go to the wireless connection settings menu. Most often, problems arise due to incorrect IP address settings. Place a marker next to the phrase: “Install static Wi-Fi.” After which you will need to enter data from the documentation or received during activation and

How to connect Wi-Fi on an IOS phone

In general, the setup algorithm does not differ from that given for Android devices. The Wi-Fi module is activated using the phone settings, and among all the networks you need to select the one you need.
If there is no connection, you must also enter the IP address and other settings. After you save them, and the router. Typically, this procedure is sufficient to restore the connection.
Also, when entering your password, check whether you are entering the letters correctly. It is necessary to take into account not only the keyboard layout, but also the case of letters. This rule applies to any device, and the password must be entered regardless of the operating system.

What you need to pay attention to if your Wi-Fi connection is poor

The correct module is not always able to fix the problem when Wi-Fi does not work on the phone. If there is no connection or data transmission is malfunctioning, the reasons for this may be the following:
. Poor quality firmware. Often, users independently change the firmware to one that will provide additional advantages in using the device, for example, unlocking the use of SIM cards from any operator. It is possible to solve the firmware problem by installing the original version.
. The modem settings have MAC address protection installed; it can be removed by carefully checking the settings.
. Your network experience can be affected by various applications running in the background. Before setting up Wi-Fi, check all running programs through the manager and stop unnecessary ones.
If the measures described above do not help, then you can contact a service center, whose specialists will check the Wi-Fi module for functionality.

Factory reset to restore via Wi-Fi

Before using a last resort and contacting a service center, you can try one more method. First, create a backup copy of all data stored on your device. Then, using the debug menu, roll back the settings to factory settings or reinstall the system. Depending on the manufacturer, the reset is carried out in a certain way.
This method is suitable in cases where, upon purchase, Wi-Fi worked well without failures, and then over time it stopped connecting for no apparent reason. In any case, it makes sense to try to check not only the receiving device, but also the transmitter. Now you know why Wi-Fi does not work on your phone and how to fix it.

The phone can be used not only to make calls and send messages, but also to access the Internet. Nowadays, mobile operators are trying to offer their subscribers services on the most favorable terms, but to save traffic, most often, if possible, they use Wi-Fi (paid or free high-speed Internet).

To operate this network, you need a transmitter, that is, a router or ADSL modem and a device that is a receiver, which can be a phone, computer or tablet. Often, when using such a network, the question may arise as to why Wi-Fi does not work on the phone.

First of all, you should check that Wi-Fi is connected on your phone, and only then find out the reason why Wi-Fi is not working on your phone.

In fact, there are several reasons for this:

Incorrect operation of the Wi-Fi distributor due to incorrect configuration settings;
Failure of the modem or phone due to mechanical damage or manufacturing defects;
Inability to access the Internet due to the antivirus program installed on the phone or tablet;
Viruses;
Error when entering Wi-Fi password;
Non-licensed firmware of a mobile device;
Date and time mismatch, etc.

Now let’s take a closer look at each problem when using Wi-Fi separately, as well as how to fix them.

Incorrect Wi-Fi setting

If you are unable to connect via Wi-Fi to the Internet on any of the possible devices, including through a computer or laptop, then it is likely that you are experiencing a network failure, lack of payment, or incorrect settings were made when connecting the router or its breakdown.

To check the options, first check your balance, as a rule, if there are no funds, if you click on any open tab in the browser, you can see a request to top up your balance. If you have done this or the payment time has not yet come and the router is not working, connect directly to your computer.

If this also does not help, then the router may not be working correctly. In this case, you can try to solve the problem yourself. To do this, you will need to go to the wireless connection settings section.

Then select the “Channel” line, it should have the “Auto” mode.

Also check "Mode", it should say "Mixed 11bgn". It is also worth disabling MAC address filtering. After this operation there should be no problems connecting to Wi-Fi.

Do not forget that any company providing services has a special customer service hotline that you can call and find out the cause of the problems.

Also, if necessary, you may be given step-by-step instructions for troubleshooting or offered to call a technician. If the equipment malfunctions, you will need to buy or replace it with a new one.

Malware and antivirus programs

There are many different virus programs on the Internet that can harm a mobile device when connected to an unsecured connection. In addition, refusal to connect to a Wi-Fi network may be precisely due to the penetration of malware that affects such a connection.

Therefore, try to install a good antivirus program on your phone or tablet before you start using the Internet. After this, run a virus scan, clean them and restart the device.

However, there are often cases when security programs also prevent access to the Internet. The most common problem of this kind is Kaspersky and Avast antivirus. If this situation occurs, remove the antivirus and reboot the phone, then look for another security program.

Incorrect password or time and date error

As a rule, if Wi-Fi belongs to someone, for example another person, then in order to protect other people from using the network, a password is set.

In order to use it, you will need to know the access password. If you know it and after entering it you cannot connect, then check it is correct and enter it again. Be sure to check if the network is working. If yes. It's worth checking your phone.

Rarely, but still, there are situations when Wi-Fi on a mobile device does not work due to a mismatch of time and date settings. If discrepancies are found. Be sure to make changes.

Bad firmware

Before you start setting up, you need to make sure that Wi-Fi is active. To do this, in the “Wireless networks” item, in the list of networks available for connection, select the network you need. If you use a home router, then the identifier for accessing the network can be found in the agreement with the Internet provider. If you are using a public network, your network credentials are usually posted in plain view of visitors.

If your chosen connection is active, but you still can't figure out why you can't connect to Wi-Fi, try changing your network settings. To do this, you need to go to the connection settings menu. Problems usually occur when the IP address is set incorrectly. You need to put a marker next to the line “Install static Wi-Fi”. Next, you need to enter your network login information, which you can find from the attached documentation or receive when activating and configuring the router.

Connecting Wi-Fi on an iOS phone

The principle of operation and the algorithm for setting up the device are practically no different from those discussed for Android. In the phone settings, you need to activate the Wi-Fi module, and then select the desired network from the list of networks. If there is no Wi-Fi connection, you need to enter the IP address and change other settings.

After this, you need to save the settings and reboot the router and phone. This procedure is usually sufficient to restore the connection. Also check if you are entering the letters correctly when entering your password. Don't forget to take into account letter case and keyboard layout. This rule applies to all mobile devices, regardless of the type of operating system used.

Poor Wi-Fi connection

Even correct configuration of the Wi-Fi module and modem does not always solve the problem associated with connecting to a wireless network. The reasons for the lack of connection may also be the following:

Poor quality phone firmware. Many users, trying to update their phone, change the firmware themselves. This action can both make working with the device easier and cause a lot of inconvenience. If you cannot connect to a wireless network due to the use of a different firmware, you will have to install the original version.
- MAC address protection is installed in the modem settings. In this case, you need to disable protection.
- network performance is affected by applications running in the background. To fix this problem, check running tasks through the manager and stop those that you do not need at the moment.

If all these methods do not bring results, you can try contacting a specialized service center, where professionals will check the functionality of the Wi-Fi module.

Owners of mobile devices based on Android operating systems sometimes, not often, however, are faced with the problem that in some cases Wi-Fi does not work. What this is connected with and how to get rid of such a problem will now be shown.

Wi-Fi does not turn on on Android: possible reasons

As for the manifestation of such failures, there are plenty of reasons for them. However, among all their diversity, there are several basic situations that occur more often than others.

If you make an approximate list of possible reasons why, for example, Wi-Fi on a smartphone (Android on board) does not turn on, it will look like this:

incorrect login password;
wrong date and time;
malfunctions in the device software;
problems with settings;
exposure to viruses;
inappropriate firmware;
incorrect router settings.

Based on this list, let's try to consider the method for eliminating each problem. In most cases, the solutions proposed below fix the problem, as they say, one hundred percent.

checking the password

One of the most common reasons is an incorrectly entered password that was set when connecting to a virtual network.

As is already clear, if Wi-Fi suddenly does not turn on on your Android tablet, and the password was saved automatically during the previous connection, it is very possible that it was simply changed. To solve the problem, go to the settings of the wireless module itself, delete the old password and enter a new one. As a last resort, just check the correctness of the input (maybe the keyboard layout has been switched).

Date and time settings

Another reason (albeit quite rare) is incorrect settings of the date and time on the gadget itself. In some, so to speak, abnormal cases, this can lead to such problems.

The method for fixing when Wi-Fi does not turn on on Android in relation to this particular situation is to go into the date and time settings and, in addition to manual settings, use the date, time and time zone of the network.

Software failures

It also happens that the problem is “buried” much deeper. For example, there are known cases when the Wi-Fi button on Android does not turn on. What does this mean? Yes, only that a critical failure occurred in the software responsible for the functioning of this module in the system.

As practice shows, it is not always possible to automatically correct this state of affairs. Therefore, many experts recommend installing a special utility called Wi-Fi Fixer. It is notable for the fact that you don’t need to change anything in its settings and parameters. The program is simply installed on the device, launched, and automatically corrects errors while scanning for possible problems. True, this doesn’t always work.

Settings failures and general reset

If the previous methods did not help and Wi-Fi still does not turn on on Android, it is very likely that there is a malfunction in the operation of the system itself or in its settings. A complete reset of the parameters to the factory state can be a remedy for the situation, and at the same time a cure.

In this case, in the recovery and reset section, you should first check the box next to the auto-recovery line (after the reset, when you reboot the system, all personal data and files, including applications, can be restored without problems). Then a hard reset is simply selected, followed by a system reboot. By the way, note that in this case there is no need for a hard reset, everything is restored just fine (provided, of course, that the system is not infected with viruses and has the original firmware).

Viruses

Exposure to viruses can also cause Wi-Fi to not turn on on Android. Today you can find a fairly large number of owners of mobile gadgets who prefer not to use standard anti-virus applications, believing that they greatly load system resources. This is partly true. However, modern mobile antiviruses can not only prevent viruses from entering the system, but also block access to the device if it is lost or stolen.

If you have a problem with viruses, you should install the appropriate application. But what if Wi-Fi doesn’t work? Yes, very simple. Firstly, the program can be downloaded as an APK file from a computer, then transferred to a removable memory card and installed, after which it can completely test the system. Secondly, the installation can be done directly from a computer terminal or laptop if you have a control application like PC Companion or something else, naturally, using a gadget connected using a regular USB cable.

What to install is a personal matter. However, among the variety of such applications, we can recommend 360 Security, which today is recognized as one of the most powerful, the same Dr. Web or McAffee. However, as is already clear, it is very difficult to advise something specific.

Firmware problems

Another reason that Wi-Fi does not turn on on Android may be an incorrectly installed unofficial

The situation here is that the firmware may be installed without problems, but it was originally designed for a different gadget model or has software flaws. Here you will have to remove it and restore the factory shell. This is done differently for different devices. The only thing in common is that you can’t do it without specialized software installed on your computer. In the simplest case, this can be done using the same universal PC Companion utility.

Router settings

Finally, it may well happen that the access settings on the router have gone wrong. In this case, we are considering a situation where the owner of both the router and the mobile device is one user, and there is no connection to an external private network.

Please note that in the wireless mode settings on the router, the channel selection field should have the option (“Auto”) set automatically, the mode line should be set to “Mixed” (11 b/g/n), and filtering should also be disabled MAC addresses (OFF).

If all else fails

It remains to add that if none of the above methods gave a positive result and Wi-Fi still does not turn on, most likely the problem lies in the Wi-Fi module itself. The device will have to be taken to some service center to conduct a full hardware test. If this is where the problem is, the module will have to be replaced.

If WiFi does not turn on on Android, this may be due to errors in the firmware and hardware malfunctions. Sometimes resetting the settings or flashing the firmware helps solve the problem. But in “severe” cases, it may be necessary to replace damaged components.

This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

The reason why WiFi does not turn on is software errors

The reason that Wi-Fi does not turn on may be a system failure. To fix it, reboot your device.

Increase

If the problem persists after rebooting, remember when the error appeared. If the module stops turning on after flashing, then the optimal solution would be to re-flash the device and install the official Android build for your model.

Wi-Fi cannot be turned on or off via - it only has a radio testing tool. Therefore, if any software failures occur in the operation of the wireless network, you should perform a reset or flashing. But before you start these operations, do not forget to backup your data.

Increase

If the Wi-Fi icon in the settings turns green (or highlighted depending on the model), that is, the module is actually functioning, but the Internet does not work, check the following factors:

correct date and time setting;
The entered access point password is correct.

If the password for the access point has changed, and old data is stored in the WiFi module settings on Android, then the connection will not be established. To change your password, go to your Wi-Fi settings. You can enter a different password into the access point settings or simply delete it and then connect again.

The reason for WiFi not turning on is hardware failure

If everything is in order with the settings and the system, but Wi-Fi categorically refuses to turn on, then you should contact a service center for diagnostics. There may be a hardware problem. Among the common reasons:

module failure;
low-quality components on cheap devices;
mechanical damage after an impact or fall.
moisture ingress.
