Why WiFi is constantly on the phone. The Wi Fi button is not turned on on Android: Causes and How to Solve the Problem. Reinstall WiFi driver in Windows: video

One of the most common problems of the owners of mobile computers is, when the laptop does not connect to WiFi and stopped working wireless Internet. Usually the wireless network does not work after updates of the Lapplet software or router, as well as a fresh operating system, which was recently installed on the PC, does not see the Wi Fi network.

The main thing in this situation determine the reason why I stopped working normally a laptop. And there is no reason for the reasons that sometimes even a highly qualified specialist cannot immediately correct the problem. Below is a step-by-step instruction of eliminating this fault.

1 stage - determination of the cause

If there is no Wi Fi network, then the reason lies not always in the computer, and the most likely the problem with the Wi-fi translator device. In connection with this statistical fact, at the first stage, it is recommended to clarify whether the router itself stopped working.

To this end, you just need to enable Wai Fi on another device. If you catch the right networks successfully manage and the gadget works on the Internet normally, then the reason is in the laptop. If the device does not see the desired wai fay, then the reason is in the router. Below are specific recommendations what to do in each of the specified situations.

2 Stage - Enable Wi Fi Adapter in Computer

When identifying the reason in the PC, start solving the problem, it is advisable to analyze the current position of the laptop wireless network adapter, and if it is turned off, it is necessary to simply turn it on and try to connect to the Wi Fi network again.

Lappops are equipped with special light bulbs showing a wireless network status and various methods to enable WiFi. In the overwhelming majority of cases, the LEDs indicating the WiFi status are mounted on laptops in front or on the side of the PC panel, but it happens that they are installed on the peripheral part of the display or inside the WiFi power key (in any case, manufacturers try to make the adapter indicator to the visible part of the laptop).

The adapter is turned on in the following ways:

In 1 method, simultaneously pressing the "Fn" and the button with the image of the Wi-Fi icon. In 2, only one key, and in the 3rd - you want to turn on, moving the switch slider.

If Wi-Fi does not work after executing the second stage of the instruction, it is necessary to continue to make the specified manual further and proceed to the next step.

3 Stage - Enable WiFi tools

In addition to methods for activating the adapter with physical keys and switches, there are ways to enable WiFi through the OS in the computer.

To this end, it is required to make the following algorithm of actions:

In the case when for some reason, the laptop cannot enter the Internet you need to start working with the instructions of the next step.

4 Stage - Debugging Software Wireless Module

It is required to analyze the performance of the Wi-Fi module drivers.

To do this, perform the following steps:

Note: In the absence in the "Network Adapters" window, the user devices are required to install the drivers. Software usually goes on a CD bundled with a computer. You can also download them from the official resource of the manufacturer of the equipment.

5 Stage - if the reason is in the router

At the initial stage of the instruction was analyzed why Wi-Fi stopped working in the PC and the most likely direction of action to troubleshoot network problems. But, since the stamps of routers today there is a huge amount and not less than firmware to routers, so at this stage will have to be limited to generalized wishes for debugging the device.

So, when except the laptop and another gadget also sees the network, then the cause of the problem is likely in the router. Below is a list of actions that make the user in such a situation:

1. Can help reduce the remoteness of the laptop from the router. It is recommended to experiment with the location of the devices and turn on the wireless network. A positive result may appear after eliminating interference, such as large furniture and household appliances, microwave ovens, interior overlap. When there is no signal even with direct visibility, then proceed to the next step;
2. Determine whether the Wi-Fi light on the router is shining;
3. Enter the router settings, where to analyze the following items:

A) whether the Wi Fi module is enabled;

B) whether SSID is enabled;

C) whether mas laptop is not included in the list ignored.

This is the entire list of problems in which Wi Fi does not work, and there is no possibility to enable it in the computer. Each individual case has its own nuances, for example, the Internet has stopped working and the laptop does not see the desired router on the banal cause of the device cable cliff, etc., but this is the topic of a separate publication.

Wi-Fi is a wireless technology on the local network. It is built into modern smartphones and tablets, nevertheless, sometimes wi-fi on android. Why do different types of troubleshooting arise? You can distinguish three categories among the causes:

1. Incorrect phone settings;
2. Unsuitable Wi-Fi network settings;
3. Equipment problems that creates an access point.

Due to the understanding of the network components, it is easier to determine what needs to be taken first. In most cases, the repair does not need a smartphone or tablet, nor a router or something that performs its function. What to start?

• Check if it is worth it "on the plane".
• Make sure the date and time is correctly exhibited on the phone. You can set automatic time ("Settings" - "Date and Time" - "Time Zone" (specify it) - Mark the "Time Zone Time Zone" checkbox).
• Restart the device.
• Remove network profile from mobile. Connect again.
• Check the Wi-Fi settings of the router, restart it.

What else can I do? Clean the RAM. Close programs running in the background. Sample path: "Settings" - "Applications" - "Working". Stop running applications.

Perform a restart of the phone (it is not done as an ordinary reboot). Activate the "plane" mode and turn off the device. Make sure it is not worth charging and get the battery. Let the smartphone be without it 5-15 minutes. Hold the power button for a minute. Insert the battery. Turn on the phone. Disconnect the flight mode. Try to enable WiFi. If the batteries are fixed, hold the power button for 10-20 seconds.

Turn off the power saving mode. In some devices, it is enabled by default. Enter the engineering menu. Open the dialer. On the phonySung code will be * # 0011 #. On all models, he may differ. "MENU" - "WIFI" - turn off the power saving mode.

There is a connection point, but the device does not detect it? A Wi-Fi network is created using a router, computer or phone. The settings of their networks are slightly different, but they work on the same principle.

Network created by phone. All parameters are already predetermined in the Android OS. You can only re-connect in case the password has been changed. You can also perform general problems in case of malfunctions, such as rebooting devices, re-create the network, firmware updating, reset the parameters of the device.

WiFi router. Change the router settings. Join WiFi from a computer. Open the browser. Write an ip in the address bar. Most likely, the numbers are on the sticker of the router or in the manual for it. To find out the IP router on the PC, open the console (Win + R, enter "CMD" without quotes). Write "ipconfig". Next to the "Main Gateway" will be IP. Return to the address bar. After entering the IP, press the "ENTER" button. Then specify the router data (usually both "admin" values). The parameters of the router went. Follow this path: "Extended Settings" - "WiFi" - "General Settings" - Mix the "Enable Wireless Connection" checkbox. Check if the problem was solved. Not? Change the connection mode to "AUTO" or "802.11 BGNMIXED" (devices with different standard Wi-Faya will be supported). There must be no tick next to "Hide access point." What if not worked? "WiFi" - "Mac filter" - turn it off. No opportunity? Then remove your address from the "Prohibit" list or add to the Resolve section.

On PC. Go to the Network Management Center by clicking on the lower right corner of the screen with the right mouse button. "Change additional sharing parameters" - Allow access to files and printers - disable access to the network with password protection.

Wi-Fi does not turn on

Android does not connect to WiFi? Try to follow the tips below.

Install the Wi-Fi Fixer application to troubleshoot this technology. Do not change the parameters, just install the program - everything will happen automatically.

Does not turn on the connection button? Make sure that the "aircraft" mode is not included on the smartphone? The reason could be for malicious software. Check the device for viruses. Good Android Antiviruses is Anti Avl, Norton Security & Antivirus, Sophos AntiVirus & Security, Bitdefender Mobile Security & Antivirus. Can't install them from the phone? Download APK file to a computer - you can also go to Play Market.

Make sure the applications do not interfere. To do this, boot in safe mode (turn off the smartphone - enable - during the appearance of the manufacturer's name, clamp the zoom button or decrease the volume (depends on the model) and hold it until it is turned on). Wai Fi earned after that? So, the problem is in the application. See what application works most actively when the problem happens. Disconnect it or stop all unnecessary processes.

Did you change the version of android to the unofficial? Restore the factory firmware through the recovery menu. You do not have an archive with a backup on a memory card? Look for it online or ask other users. Check the file to viruses. Go to the recovery menu - "Wipe Data / Facroty Reset" - "Wipe Cache Partition" - "InstallZipfromsdcard" - specify the path - confirm the solution.

Nothing worked? Perhaps the radio module is broken. It is necessary to attribute the device to the service center for repair (which is preferable if there is a valid warranty coupon) or to the experienced verified master.

I can connect, but the pages do not open

Android users sometimes say: "I can connect from the phone, but no Internet." The simplest thing is to travel to restart your smartphone or tablet. This will help if a small program failure occurred.

Probably case at the point of access. Make sure the Internet accounts are paid - the provider could suspend the delivery of services due to non-payment. Check the router settings. It should not be included with the limit on Internet traffic or forbidding sites that you need. Most often, this problem occurs during the use of public networks. There is a chance that the problem is on the side of the provider. If anything does not help anything, it makes sense to contact him or official sources for information.

Forget the network as follows:

1. Open the "Settings" - "WiFi".
2. Check the network name before the menu appears.
3. Click "Delete".
4. Disconnect Wi-Fi. Wait a few seconds.
5. Turn on again. Wait until the network is found.
6. Enter the password (if installed) and connect to the access point.

Did not work? Proxy must be disconnected.

• Go to "Settings" - "WiFi".
• Check the network name and click "Advanced Settings" (or "Advanced").
• The value of the string "Proxy server" must be "no".

Multiple network users may mistaken be under one IP address, which makes it impossible. How to fix it?

1. Disconnect all connected devices from the router.
2. Turn off the router for a minute.
3. Attach one device to it.
4. Wi-Fi works? Attach other devices.

Authentication error

Often, users see the text: "Saved, WPA / WPA2 protection". It happens after an unsuccessful connection. Later, the "Authentication Error" may later pop up. Why not turn on Wi Fi on android? The password is entered incorrectly. The parameters of the Wi-Fi network are unsuitable. May write "saved". What if you met this problem?

• Check the password input correctly.
• Change the router parmeters (how to enter them above). Change the mode with "auto" or "n" to "802.11 b / g".
• Change the region in the United States or Russia.
• In the router parameters, place the "WPA" authentication method, and the encryption "AES".
• Specify the free channel. Can help the tire replacement for 20 MHz.
• Try to make a password on Wi-Fi only from numbers.
• Follow the "Settings" paths - "More" - "Modem Mode" - "Setting the Access and Conjugation Point" - specify "IPv4 and IPv6" - TW-modem Turn off. Go to the "VPN" section, set the password and remove. Activate and deactivate flight mode. Wi-Fi should turn on.

We hope the problem is eliminated.

Each user is sooner or later faced with the fact that for some reason Wi-Fi does not work on the phone. This article is intended to help identify the sources of these common problems and choose the fastest and most effective way to eliminate them.

So let's understand!

The incorrect functioning of the wireless communication is usually caused by several reasons:

• Invalidly specified Wi-Fi settings.
• Errors in the work of the router itself.
• Invalidly specified mobile device parameters.
• The action of malicious programs or antivirus software.

Below, we will consider in detail each item and formulate recommendations for troubleshooting. All of the following is relevant for both Wi-Fi on Android, IOS, and for other operating systems.

Elimination of the problem

You can only cope with the problem in the event that it is accurate to determine its cause. For this, it is not always necessary to contact the specialists. Many errors that concern, for example, wireless parameters can be identified independently. If the Internet slows down, slowly works, this may be due to third-party factors: for example, a network overload when many gadgets are connected to it. Sometimes slow Wi-Fi is the reason to check the computer itself or the connection line of your provider supplying the Internet.

Incorrect Wi-Fi Setup

First of all, attention should be paid to how the Wi-Fi access point is configured. To do this, you need to access the router menu via the browser: but you will need to enter a number of characters in the address bar, the combination of which is individual for each device. Usually, these data are on the back of the router, look for lines of login and password, they will be required at the next step.

Enter the username and password. If access to the menu has managed to get, first of all, it is worth paying attention to the parameters of the wireless mode. Several simple options are relevant here:

• Channel - AUTO, but you can try to put another channel.
• Mode - 11 BG Mixed, but the parameter change to 11 BG Only can give a positive result.
• Channel Width - AUTO.
• The transfer rate, if it is, is set to the maximum value.
• Region is not enough for what affects, but theoretically can be a source of malfunction.

If everything is configured correctly, the Internet still functions incorrectly, you should contact the service center or look for a problem elsewhere, for example, by contacting the provider. The device can be defective technically, so it is recommended to check it immediately after purchase.

Routher settings

Check if there is an opportunity to enter the Internet at all. If it is not with both a personal computer, and from another device, it is advisable to check whether the router itself is enabled, whether it works correctly. This signal indicators.

The power indicator should burn green. Next to it is a system indicator that should flash. The following indicator - WLAN - shows whether the wireless connection is enabled on the router itself or in its menu. Next are the numbered LAN ports, the cable must be connected to one of which. Ideally, he should also flash. After them, it usually goes WAN, whose indication says that the router is connected to the Internet.

In some cases, the connection has been helped.

Incorrect time or date

Wi-Fi on a mobile device may well function because of such trifles, as the wrong date is one of the first in the list of common causes of Internet problems. You just need to go to the Settings section, set correct values. It is important to consider the time zone correctly.

Error in the password to Wi-Fi

Another possible reason is a password. If the connection to the access point on the phone occurs automatically, this error occurs when a password is changed by the user. In other words, the password is changed, but the gadget itself "does not know" about it "and automatically introduces the old one. Solution, again, simple - create a new connection and enter the correct password.

Malicious and antivirus programs

Wai-fi may also interfere with the viruses that the smartphone "caught" on the network can be interferent. If you suspect infection, it will be appropriate to install an antivirus program on the phone and check. There are many such programs, but usually used brands like Kaspersky and ESET NOD.

Other side of the medal: Antivirus and other protective programs, such as firewall, can be a source of problems. Antivirus creates a kind of "shield" to filter traffic, which sometimes affects the connection. If, after removing the anti-virus software, the connection is working correctly, in this case you have to try another software or refuse it.

Failures in Po

Many users have a wireless connection due to incorrect software. For example, when a user establishes an alternative firmware or any other intervention in the factory characteristics of software is carried out.

Other errors in the operation of the gadget are also indicated about the problems with the android system - permanent, systematic hangs, arbitrary shutdown and others.

In this situation, you can make Hard Rest - it will return the system to the factory parameters.

If the case is in the firmware of the phone - this will help to solve it. But you need to know that "not native" firmware is thus not deleted.

When the source of incorrect work lies in the router, it is often necessary to simply restart the router. It is not always easy to do, because some models are not equipped with the ON / OFF button.

If there is no reboot function on the device itself, you can simply pull out the cable for 10-30 seconds.

It can also be performed through the machine menu. The order of input is described above. This method is relevant in the event that it is difficult to get to the router itself or it is impossible. The "Reboot" option in different models of routers is located in different parts of the menu, but, as a rule, on the system settings tab.

If the Wi-Faya error is due to the software failures, you can try to restart the device. In addition to the standard "restart", there are several more methods, more radical and solid:

• Through the menu: "Restore and Reset".
• Through entering the number * 2767 * 3855 #.
• Through Recovery MOD - it can be called by closing at the same time "home", "Enable" and a decrease in volume. Next, select the section "Wipe Data".

Other problems

If these recommendations did not help restore the normal functioning of the wireless communication, it is possible that the technical malfunction of the Wi-Fi module itself. In this case, it can only help a qualified specialist.

Conclusion

Questions with the functioning of Wi-Fi, as a rule, are solved easily and without attracting specialists. But it is worth remembering that independent technical intervention can damage the car until the loss of the functionality. If the difficulties with the connection are not solved in the available ways, it is better to contact the service center.

The Wi-Fi module in the tablet or telephone on the Android operating system is one of the most important components today. Wireless networks surround not only at home, but also at work, in favorite coffee houses and even in public transport. Wi-Fi does not turn on Android usually at the most inappropriate time. Why can it happen? Several options:

• the password is incorrectly entered;
• setting up the settings of the network connection or system;
• there was a failure in the operating system;
• unsuitable firmware was installed;
• wi-Fi module itself failed.

Most often, the problem is in the settings. Of course, if the smartphone fell into the water, there is a possibility that something is wrong with the module. But if nothing happened, and the network disappeared suddenly - the mistake most likely software.

If Wi-Fi does not start on Android, first of all, you should:

Often the reason for non-working Wi-Fi is very simple. But it does not always lies in the wrong passor or a bitten. If after all actions the Wi-Fi icon is still gray, it's time to move to more resolute.

Restoring settings

The simplest Wi-Fi recovery solutions are to exhibit the right date and time. If the "airplane" mode is not active, and the date and time are correct - you can try to reset the device to factory settings. After preserving the data in the cloud storage or on another device.

Android users have come across the problem of eternal download when trying to update or install applications via Play Market. On the network performance, this also affected. If this is your case, try cleaning the PLAY MARKET cache, delete temporary files.

Routher settings

Do you go to additional settings and you are written "Mac Address is not available" error? Disconnect Wi-Fi on the device, as well as the router itself. After some time - connect back and try to enter the network again. If it did not help, the encryption settings on the router may have been changed. Some Android devices simply do not see the encryption channels above 11. Change the router settings and connect again.

Android Engineering Menu Settings

If your device is based on the MediaTek processor (most devices with the Qualcomm processor there is no such possibility), you can exit the engineering menu and set the Wi-Fi settings directly through it. You can open it by command "* # * # 3646633 # * # *" \u200b\u200bentered in the number dialing panel. For some tablets that do not have this panel, you can install special utilities for accessing engineering mode. Settings are checked and installed in the "Connection" tab.

Customize something through engineering mode only if you are an advanced Android platform user. This is a mode for developers, any changes in the method of the Tyk may lead to unpleasant consequences.

Wi-Fi settings on the TV-BOX console based on Android

Boxing Boxing Prefix, which also works on Android, like smartphones with tablets, also does not remain without problems with the connection. To work with it it is recommended to use an external Wi-Fi adapter or connect the cable, but this will only help improve speed. And if there is no Wi-Fi connection at all, it is recommended:

1. Go to the file manager.
2. Find the WiFi folder and in it the WPA_SUPPLICANT.conf file.
3. Delete a file.
4. Wait a while, start searching Wi-Fi on the console.
5. The device will automatically find the connection.

Did not help? Time to check the software.

Software failures

Do not work or arbitrarily disconnecting Wi-Fi may be due to recently installed applications. Enter the application manager on your mobile device and look at which one of them has the greatest activity during departure. Such an application is usually more and mercilessly eating a battery, so the smartphone or tablet "dies" faster. It will be enough to remove the application or put another version with which the error was not observed.

It is recommended to check if you should not have applications that restrict access to the Internet. So through a series of firewalls to put restrictions, even without root rights. Also, for checking software, there are special utilities, thanks to which you can see, thanks to which application, the network gives an error. Additionally, it is recommended to check the device for viruses - some of them can create problems with a network connection via Wi-Fi.

Installing inappropriate firmware

The cause of problems with the work of the Wi-Fi module can be in a custom firmware blocking the connection. Manufacturers recommend installing only the official versions of the firmware: custom options are not always trustworthy. If problems have appeared after flashing, you should roll back the device to factory or reflash again. Only already on the official one.

When a user acquires a laptop, of course he wants to use all the capabilities that it provides. The topic of today's article, how to enable WiFi on a laptop in Windows 7 or 8, I chose not enough. It would seem that there is nothing difficult here, but if you do not know some nuances, then this procedure will seem not so trivial.

Problems may arise and fortunately they quickly and simply decide, just to know enough - how exactly. Just in this article, let's talk about some submarine stones that may occur when Wi Fi is turned on.

Is there Wi-Fi in general

First of all, we have to find out if Wi-Fi is in your computer or laptop. In modern portable computers, laptops, netbooks, phones and other devices there are Wi Fi. You can check whether your device can be in Google, but I can assure it right away that if you purchased it a long time ago, the built-in receiver can simply be there.

When you look for the technical characteristics of your device, look for the Wi-Fi selection of the same name. For example, a description of the laptop ASUS:

Physical inclusion Wi Fi

Some laptops have a special slider to be moved, to enable or disable Wi-Fi. So that you understand what I'm talking about now, look at the image:

There may be an inscription near it: "OFF" or "0" - turn off / off, as well as "on" or "1" - enabled / enable. Usually it is placed on the right or on the left of the laptop, and may also be on its front.

There are models of laptops, where to enable or disable Wi-Fi, you must click on the corresponding button, which is in the image below (button on the left):

Completely, laptop manufacturers make this button highlightening: for example, when Wi-Fi is turned on - lit, if it is turned off, then the laptop will not highlight this button.

Although it is not always so, that is, this button does not turn on, thereby need to determine your Wi Fi yourself. To do this, pay attention to the indicators on the front of the laptop. If you enable Wi-Fi, then the indicator that is responsible for this device must turn around, so it gives to understand the user that now you can use it.

Function keys (Fn +)

On laptops from various manufacturers, this procedure is slightly different. Consider hot key combinations that can be in your laptop:

1. Acer. Click the keys: "Fn + F3".
2. ASUS. Combination "Fn + F2".
3. HP. Here you press "FN + F12".
4. Lenovo. The desired buttons: "Fn + F5".
5. Samsung. Either "Fn + F12" or "Fn + F9".

The above was listed ways to include WiFi on the most popular laptop models. However, it is impossible to ensure that you have one of these laptops.

The FN button can simply be missing. Then most carefully inspect all the keys on the keyboard. On one of them should be drawn the WiFi network icon, press it and the network will turn on.

Below you can see what the wai faya icon looks like:

In the screenshot you can see that on this laptop it is necessary to press "Fn" + "F2".

Turn on Wi-Fi in Windows

If you have made the above methods, but it did not work out to connect to Wi Fi, we do the following: We pass in the "Start" menu - "Control Panel" - "Network and Internet" - "Network Management Center and Common Access". On the left, click on the item: "Change the adapter parameters".

Press the right mouse button on: "Wireless Network Connection" and select "Enable".

If there is no such item, but there is a "disable", then Wi-Fi in Windows-E is enabled.

After that, Wi-Fi should earn, but if it did not help, or some error occurred, or there is no network with such a name, the question arises: "How to enable WiFi on a laptop then?". We read on!

If our laptop does not automatically connect to the desired network, then the problem may lift in the fact that the signal receiver device is disabled in the Device Manager. Now I will show you how to fix it with the example of Windows 7.

Go to the "Start" menu, click on the computer right-click and select "Properties".

In the window that opens, click on the left "Device Manager".

From here you can watch: what components in the laptop can be controlled - activate or disable the desired device. Find something in the title of which the word is present Wireless.. Click on it right mouse button and select the item "Enter".

By the way, if a yellow triangle with an exclamation mark is next to the service icon, it means that the driver for this device is not installed on the laptop. In this situation, use another device (computer, laptop, netbook, tablet, etc.) through which you download drivers for Wi-Fi-Aya, transfer to a laptop and install them.

Other Wi-Fi Inclusion Nuances

Above, I told in detail how to enable WiFi on a laptop. But that you see a complete picture, how to enable and how to connect to Wi-Fi, ultimately follow the link on, because in this article I tell about other nuances that may arise in your case. The article "" wrote on the "living" example, so it will be extremely useful for you.

If you are not familiar with the installation of drivers, then read: ". To find the driver, go to the official website of the manufacturer of your laptop, enter the model in the search site. After that, in the list, look for a driver for Wireless.

I do not exclude that users who read this article do not know the password to Wi-Fi. If you do not know it, you can not go to the secure network. To find out how to see the password for Wi-Fi, I recommend to reading: "". Also assume that some will ask about hacking, yes, it is possible to hack, but I will not write about it.

There are different situations and no need to exclude the possibility when none of the above councils will help you. How to do then? Fortunately, there are third-party software that you can easily use. Its meaning is that after installation, this program, with each Windows startup, will automatically turn on and by pressing a specific key combination, perform certain actions. For example, turn on Bluetooth or WiFi.

There are a huge amount of such utilities, I can lead as an example SoftSwitch. In addition to the above functions, it also knows how to include the camera and Touchscreen. For each of these functions, there is a certain combination of keyboard buttons with which you can read if you decide to download this creation programmers. Find this program in Google will not be much difficulty, as it has a Free Soft license (free license). Download it, install and rejoice!

And I have on this issue, perhaps everything. Thanks for reading and I sincerely hope that he helped you.
