Ways to solve problems connecting to a Wi-Fi network (Internet). Wi-Fi doesn't work: tips and solutions

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 it possible problems on one's own.

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. In modern mobile devices- tablet PCs and smartphones - available great feature- saving 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 was created for such devices a large number of malware. 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?" may also be due to the fact that there are some difficulties in software gadget. 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 save first important information to third party 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.

Wi-Fi technology is very widely used in life modern man, because it allows you to easily and quickly solve problems with connecting to the Internet without using conventional wires. This is especially true when using laptops, which can be used to access the Internet in any convenient place thanks to the presence of a built-in Wi-Fi adapter.

That is why the situation when Wi-Fi does not work on a laptop leads to significant inconvenience and even some problems. There are many reasons why Wi-Fi may not work on a laptop computer. It is simply unrealistic to solve the most serious of them on your own without the help of specialists, but there are quite a lot of them that can be eliminated on your own. Let's look at them.

Is the problem with your laptop or router?

A fairly common problem that a laptop has stopped connecting to the WiFi network is not a problem with the laptop itself, but with the settings of the router that distributes the network. Thus, the laptop can be configured correctly, but Wi-Fi still does not turn on precisely because it has nothing to connect to.

To rule out the possibility that the problem is related to this, you should try to connect to the network from any other device that is equipped with a Wi-Fi adapter - from another laptop, smartphone, tablet, etc.

If Wi-Fi does not work from another gadget, then the problem lies precisely in Wi-Fi router e distributing the Internet. If the connection is successful, the problem is in the laptop and before solving it, you first need to determine why Wi-Fi stopped working.

Hardware enable adapter

Based on such diagnostics, it is possible to accurately determine that this problem arose precisely because of the laptop. When Wi-Fi does not work on it, you can try using several methods.

The first one is to check if the wireless adapter on your laptop is enabled. Almost all modern models have light indicators for the operation of the WiFi module and there are special key combinations to enable it in hardware.

Typically, a lit indicator indicates that the module is turned on. If the indicator does not light up at all or lights up in red, then Wi-Fi is not working precisely because of the wireless network adapter. It must be turned on.

Most often, such indicators are located directly on the keyboard, side or front panel of the device case. Sometimes they are located on the monitor body or near the touchpad.

To enable the module of such a network, press the key combination Fn and one of the system keys F1-F12. The specific combination depends on the laptop manufacturer. Usually, the corresponding antenna icon is located on the desired key. If it is not there, then to turn on Wi-Fi you should try pressing the standard combination for a particular model:
Fn+F3 for Acer;
Fn+F2 for Asus, Dell or Gigabyte;
Fn+F5 on Fujitsu devices;
Fn+F12 on HP laptops.

After pressing the corresponding keys, we check whether the wireless connection module operation indicator lights up or whether it stops glowing red. After this, you should try to connect to the network again. If this does not help, move on to the next step.

Software enablement

When Wi-Fi stops working and turning it on in hardware doesn’t work positive results, you also need to enable it programmatically, which is done directly from the operating system under which the laptop runs.

To programmatically enable WiFi that has stopped working on Windows 7, 8 or 10, you need to perform the following sequence of actions:

1. On the notification panel, which is located near the clock, select the network connection status icon;

2. From the list that opens, select “Network and Sharing Center” or “Network Settings” depending on the version of the operating system;

3. The next step is “Changing adapter parameters.”

Among the list of all existing connections You need to pay attention to the color of the “Wireless Network Connection” icon. If your WiFi does not work and the wireless adapter is disabled, the connection icon will not be highlighted. In this case, right-click on its icon and select “Enable” from the context menu that opens. The color of the connection icon should change.

In this case, the wireless network adapter turns on, all you have to do is find the one you need in the list of available wireless networks and connect to it.

If, after such actions, Wi-Fi, which has stopped working, continues to be inactive, you need to proceed to to the next method solving the problem.

Driver installation and update

Quite often, the wireless Wi-Fi connection does not turn on due to the lack of a driver or when it is very outdated. To determine whether the driver is installed, you need to select “Properties” from the context menu of the “My Computer” icon, which is located on the desktop or in the “Start” menu. Next, in the window that opens, select the “Device Manager” command from the menu on the left.

In the new window that opens with a list of connected devices, you need to find the name of the laptop’s wireless network adapter. Usually its name is “Wireless Network Adapter” or “Wireless Network Adapter”, along with which the device manufacturer should be indicated: Realtek, Atheros, Qualcomm or something else.

Having found the desired item and right-clicking on it, select “Properties” from the context menu. In the window that opens, there should be an item “Device is working normally.” But even if there is a mark about normal operation device, this is far from a guarantee that the correct driver version is installed and Wi-Fi is turned on correctly. To check it, in the window with the properties of the wireless device, go to the “Driver” tab and pay attention to the items “Date of development” and “Vendor”.

In the event that the supplier is Microsoft or the date of development of the program is several years behind the current one, go to the official website of the laptop manufacturer and download the latest official version drivers.

The same should be done if there is no wireless adapter among the list of installed devices.

If in the list of devices the module wireless communication is present, but marked with a yellow exclamation mark, this means that the device is disabled, as a result of which the network stopped working. In this case, opening the device properties window, you need to click the “Engage” button.

Another reason why Wi-Fi stopped working on a laptop may be that the energy-saving mode is enabled, which prevents the wireless connection from working. To disable it, you need to do the following:
1. Open Control Panel;
2. Select the “Power Options” icon;

3. In the window that opens, select the “High Performance” or “Balanced” mode.

External obstacles to the signal

It is also worth noting that the non-working wireless network may also be the result of more than just problems with the laptop. The wireless signal depends on some external factors which may weaken it. Ceilings, walls, floors and similar obstacles significantly degrade the signal quality of the access point and laptop.

As you know, the signal quality on a personal computer is displayed in the form of several marks - the more of them, the higher the quality of the signal. If the wireless connection level is displayed as 1 or 2 marks, then you don’t have to try to use WiFi - in this case it will not work normally.

In this case, you need to move the router closer to your workplace, move workplace closer to the Wi-Fi router or buy a new, more powerful router.

If all else fails

If none of the tips above helped, you can use a simple, but often effective solution: restart both your computer and your wireless router. Please note that after a reboot, the router turns on for up to 5-10 minutes before it starts distributing the network. Be patient. Also, despite the opinion of many skeptics, sometimes the troubleshooting function that is included in the wireless network helps to solve problems with the wireless network. operating system Windows.

Thus, most of the existing solutions to problems related to the fact that Wi-Fi has stopped working on a laptop have been listed above. Almost all such methods and recommendations can be used by anyone who is faced with a similar problem, since this does not require any special skills.
If nothing helps, and the wireless network does not start working, there is only one option left - go for help to a quality service center, where they can solve any problems with the laptop.

If the article did not help solve your problem and Wi-Fi still does not work, write in the comments, I will try to help.

Hello friends! Wi-Fi Internet is no surprise to anyone now; it is available in almost every office, store, cafe and is actively appearing in homes. A large selection of routers and their low price only contribute to such an active installation of wireless access points. Almost everyone can afford to buy a router and install it at home, because it is very convenient and not expensive.

And if routers have become very popular, then the question of setting up, connecting, breaking, etc. of these same routers has become relevant. If I have already written many articles on connection, settings and various errors, which you can read in the ““ category, then today I want to talk about the most popular Wi-Fi breakdowns routers and give some tips to help you fix the device, or simply determine the cause.

There are a lot of comments left on this site about various problems with routers. And very often the cause of some error is not the settings (as many people think), namely technical problems in the router itself (in the hardware).

Today I want to talk about problems that appear unexpectedly. Like this? Well, the router worked great, distributed Wi-Fi, made everyone happy :), and then it stopped working. It doesn’t matter how it stopped working completely, or simply not how it should work. The main thing is that it used to work well and stopped working on its own (You haven't changed any settings).

It’s just that the problems that appear during the first setup of the router most likely arise due to incorrect settings.

The router does not respond to connection to the power grid

I'm sorry, but your router is most likely completely dead. On every router (well, or almost every one) There are performance indicators.

And if these indenters do not light up when you connect the device to a socket, then this is very bad.

What can be done?

Well, first check if there is a power off button on the router. There is such a button on the TP-LINK TL-MR3220:

If the button is on, then you need to check the power supply, it may be the problem. Typically, power supplies burn out more often than the routers themselves. Perhaps your neighbors have the same router, run and ask for a couple of minutes.

If the device still does not work, return it under warranty. And if there is no warranty, then it is better to throw it away and buy a new one than to send it for paid repairs. Although, you can take it to a workshop, perhaps the repair will not cost very much.

Why does this happen?

For many reasons. There may be a manufacturing defect, but most likely the router burned out due to unstable voltage in the network, a thunderstorm, or moisture. If possible, connect the router through a voltage stabilizer. Well, or just turn it off when you see that there is going to be a thunderstorm.

This was the most severe case, now let's look at milder breakdowns.

The router has stopped working and does not provide internet access

If a problem suddenly arises with Wi-Fi, for example, all devices stop connecting to the router, there is a connection, but the Internet does not work, etc. then do not rush to throw your router out the window :).

First you need to find out that the problem is really with the router, and not with the device you are trying to connect. How? Just try connecting another device (laptop, tablet, phone). If only one device does not connect, then the problem is most likely in it. Well, you understand what I mean.

The problem is in the router, what needs to be checked and how to solve the problem?

Don’t rush to immediately go into the router settings and change something there right away. Otherwise you set it up in such a way that it definitely won’t work. Believe me, I’m not just writing this :).
Reboot your router. Restart your computer (phone, tablet).
Call your provider and ask if there are any problems on their end. Explain your problem to them. Perhaps the Internet is not working due to problems with the provider’s equipment.
Check whether your Internet is paid for and whether it is active (You can also ask your provider for this).
Check all connections. Internet cable that connects to the router. It is advisable to check this cable outside the apartment (house). Perhaps your cable was simply cut. On purpose or by accident - this happens.
Look at the router case, maybe there are some interesting buttons that someone accidentally switched. For example, there may be a button to disable the Wi-Fi module. If you click it, devices will not see your wireless network.
Go to the router settings and see if the settings have been lost. This may happen and the Internet will not work. Especially, check the WAN tab, where the settings from the provider are. If they fail, set them up again. Here is an article for you as an example
Try changing the channel in the router settings. Here is a detailed article. How might this affect strange Wi-Fi problems? Perhaps your neighbors have installed a router and more than one, I will introduce neighbors above, below, on the sides. And just all the channels (or the one you are on) busy. That's when problems begin that are even difficult to explain.

Have you tried everything and nothing helps?

Then, I advise you to send the router for repair, again under warranty. And if there is no warranty, then pay for repairs, or buy a new one. Before doing this, you can ask a friend who understands this matter (if there is one) so that he can look at the router, settings and connection.

Real case. My TP-LINK TL-MR3220 router worked great for several months. Then, suddenly it stopped detecting the 3G modem connection. I connected different modems, the modem gets power, but it does not appear in the control panel. I tried everything, even the special firmware that TP-LINK support sent me - it didn’t help. You can read more in the article.

What I mean is that if a technical problem occurs in the router (something will burn out there), this does not mean that it simply will not turn on. It may work, but it won't work as intended. And it can take a very long and painful time to configure, flash, check, etc.

Don't suffer. You paid money for this device. Call support from the router manufacturer and explain the problem to them. I'm sure no one will give you best advice than them.

If support cannot help over the phone, they will advise you to apply for warranty coverage (if there is one). And then it’s up to you to decide whether to go for repairs or buy a new device.

Best wishes!

Why did the Internet stop working via the Wi-Fi router? Major router failures updated: August 9, 2013 by: admin

IN Lately wireless technologies have almost completely replaced wired ones from our Everyday life. And now almost every home, institution, office has WiFi router, allowing you to access the Internet on several computers or mobile devices at once.

WiFi technologies certainly have their advantages, but they also give rise to certain inconveniences. If you suddenly Internet disappeared with an active wireless connection, or to router access point If you can't connect at all, then you've come to the right place. In this article we will talk about the most probable reasons problems and give advice on how to fix them.

Problem 1: WiFi is connected, but there is no Internet

Since access to the Internet is carried out through network cable, supplied to the router (router) by the Internet provider (WAN port), and only then “distributed” via a LAN or WiFi connection, the first thing you must do is eliminate the problem on the provider side.

It's very easy to check this by looking at WAN indicator in the router. Typically this is an icon globe or the inscription “WAN”.

If WAN indicator is off, it means the cable is damaged or there is no connection with the provider. In this case you should contact the provider's technical support.

If indicator flashes, - there is a connection, but there is no Internet connection. This may be the result router failure. It will be required reboot. To do this simply turn it off with the button and turn it on after a minute. Wait until the router is completely configured (the gear icon stops blinking) and reconnect to WiFi on your computer. If the problem persists, contact your provider's technical support. As a rule, such problems are resolved by employees within 3 minutes.

Problem 2: The Internet periodically disappears

It happens that the Internet disappears and then appears again. There are several possible reasons.

1. Poor Internet connection. The best way check the quality of your Internet connection - use one of the tips from.

2. Router problems. Reboot it as described in the section above.

3. Bad WiFi signal. If the WiFi indicator on your computer or other device shows a weak signal, check how far the router is from the computer. The more walls there are in the way, the worse the signal. However, there may be another reason - poor contact with the antenna or its incorrect location. Make sure that the antenna is securely screwed to the router body and is not damaged.

4. Laptop WiFi adapter problems. A yellow exclamation mark may appear next to the WiFi icon in the system track. Try turning the adapter off and on. To do this, the laptop has a special function key - an antenna icon or an airplane (turns on airplane mode). Another method is performed from a Windows system: click on the WiFi icon in the system tray and in the side menu that opens (Windows 8), move the Wi-Fi mode parameter slider first to the position Off, then On. Next, reconnect to the access point. If it doesn't help, restart your computer.

Problem 3: Unable to connect to access point

A very common problem is when you cannot connect to a WiFi hotspot. There are several possible options here, so the procedure is as follows:

First of all, you need to make sure that your adapter is turned on and not in airplane mode. To do this in Windows 8, just click on the WiFi icon in the system tray and check the item in the sidebar that opens Airplane mode(it should be Off.) And WiFi(it should be On.). You can see the screenshot above.
Next, check if the adapter finds the desired access point. If it doesn’t find it, make sure your router is plugged in and working. Does not help? Let's move on to the next step.
Restart the adapter using the method described in paragraph 4 of the previous section. If it doesn't help, reboot your computer.
In case the adapter finds other WiFi networks, But does not see your access point, - there may be a problem with encryption. Try and configure WiFi security settings so that you do not need to enter a password - item “Wireless mode” -> Wireless protection -> Disable protection. That is, there should be no encryption on the network. After this, most likely, your access point will appear in the list of networks. If you really need a WiFi password, try changing the encryption type to WEP.
If the computer does not find any WiFi network and rebooting does not help, the reason may be a failure of the adapter itself.

Bottom line

We hope that this article includes everything possible options WiFi problems and that one of our tips helped you. If we missed something or you have any clarification, please leave comments. And, of course, like the post and share it on social media. networks!)

If your WIFI stops working, do not rush to contact paid services specialists or call specialists to your home. We have collected everything to help you useful tips and we present the most common problems and ways to solve them.

So, first of all, you need to make sure that there is no Internet via a wireless Wi-Fi connection. Insert the ISP cable into the network card directly. The Internet did not appear in this case either? Call your provider's support service. The problem is not Wi-Fi, but the lack of Internet access. technical reasons. Make sure your internet bills are paid on time.

What to do if the Internet works, but Wi-Fi does not work?

Try connecting to the access point from other devices. So, if WIFI does not work on a laptop, but you were able to connect to the same network from a smartphone or tablet, then the problem is in the laptop.
Perform a visual inspection of the router and all cables connected to it. The RJ-45 connector or plug may be damaged, or the antenna contact may come off. Try turning it the other way. Very often, the router fails after a severe thunderstorm (if you did not turn off the router in time and did not pull out the provider's wire from it). Problems can be easily identified by the number of flashing lights. Get your owner's manual and find out which bulb does what.

If no visual damage is found, the reason is in the settings. In this material we will not provide complete settings. You will find them in the instructions and service agreement concluded with your provider. Let's consider only the subtleties that many miss.

How to configure a router correctly

First of all, use the setup instructions provided by your provider. Many users ask why there is no Wi-Fi, and the reason may be simple - the provider, for the purpose of modernization, may change some settings and not notify you about it. Therefore, it would be a good idea to call the support service back and clarify the network parameters.

Go to the settings menu by entering the address indicated on the router body into the search bar. What should you pay attention to here?

Make sure the DHCP server is enabled. Otherwise, the router will not be assigned an IP address. To do this, go to the DHCP settings and make sure that the value is “Started” or “Enable” (if you have an English-language menu).

The data transmission channel on the router is set automatically, but sometimes it is better to select it yourself. What are the consequences of an incorrectly chosen communication channel? Signal overlays. To check channel congestion, use the Free Wi-Fi Scanner (for Windows devices) or Wi-Fi Analyzer (for Android) applications. By setting Wi-Fi channels to “Auto” mode, you give the equipment the opportunity to independently select and assign the optimal channel.

Channel width is a parameter that determines maximum speed transferring data over a certain period of time. For 2.4 GHz routers the value is set to 20 MHz, for 5 GHz routers – both 20 and 40 MHz. Setting the width to 40 MHz in a 2.4 GHz router is highly not recommended. How to switch the router to 5 GHz? Operation at 2.4 GHz occurs when using b g n protocols. N supports high throughput. But b, g are compatible with devices released more than 5 years ago. Therefore, for a 2.4 GHz router it is better to enable bgn mixed mode. 5 GHz routers operate in 802.11a/g mode (but the Wi-Fi modules on the devices must also support it).

MAC filtering provides ideal protection, but can become a serious barrier to connection. The function denies access to the router for specific devices. Or vice versa, you can specify a list of MAC addresses in the settings - gadgets that are not included in the list will not receive access. We do not recommend experimenting with MAC addresses unless absolutely necessary. Quite often, subsequently, because of this, many users do not connect to Wi-Fi and they cannot fix the problem on their own.

What to do if Wi-Fi disappears after installing Windows 10? The problem is solved by installing new drivers. They must be designed for a specific router model and for Windows 10 OS. Please note that not all manufacturers at the time of writing have released drivers that support Windows 10. You can try installing drivers for Windows 8 or contact the contact center of the company that produced your equipment.

Why doesn't Wi-Fi work on tablets and phones, but it works on a computer?

If you don't have Wi-Fi on your device iOS control or Android, it will be useful for you to know the following information. In many cases, the problem, again, is incorrect settings, although the possibility that the device is “buggy” cannot be ruled out. You can read about what to do if there is no Internet on a specific device running Android.

Before you start changing the settings, make a “backup” so that the result does not turn out “worse than it was.”

At the first stage, remove the Wi-Fi settings from the device that you are having difficulty connecting to. Otherwise, even if you change the router settings, the smartphone or phone will try to connect to the network with out-of-date settings.

So, what do we pay attention to:

Network SSID quality. SSID is the name of the network and is what you see when you find your network in the list of networks available for connection. It must be unique. Do not use your router model name or common names. If the SSID is not unique and there is already an identical name, devices will have difficulty authenticating.
You don't find your network in the list of available connections and are wondering how to connect to WIFI. It may not exist if the signal is weak or there are problems with the equipment. But also the tablet and phone will not be able to detect the network if you use closed (hidden) SSIDs. How can I determine if hidden SSIDs are being used? Make sure that the “broadcast SSID” option is checked.

If Wifi does not work on your phone, you should also check your encryption settings. As a rule, manufacturers recommend installing AES - Personal WPA2 encryption. But some devices connect only via TKIP. So you should try different types encryption. Also don't forget about the password.

This completes the description of the most common reasons why there is no Wi-Fi. We hope that this material was useful to you and you solved your problem.
