Why does the router not distribute Wi-Fi? An overview of the main causes and ways to solve them.

Navigation

Since today almost every person has at his disposal not only a desktop computer, but also a laptop, tablet, smartphone or all at once, the most convenient type of Internet connection for him is WiFi, which distributes wireless Internet to all devices immediately using a router.

As a rule, after installing and configuring the router by the master, many users believe that there can be no failures in its operation. However, this opinion is erroneous. Quite often, users are faced with a situation where the router stops distributing the Internet over WiFi, but with a direct connection, there is access to the network. Let's try to figure out what can cause such a problem and how to fix it.

Key Signs of Wireless Network Failures

Most often, when people encounter network errors WiFi, they blame the router itself for their occurrence and believe that it needs to be replaced. However, in most cases, the problem lies not in the device itself, but in its incorrect configuration and computer settings. Consider the main evidence of a malfunction:

The device cannot find a signal WiFi;
WiFi constantly reconnecting;
The wireless connection provides very slow internet speeds;
Infinite connection to the router;
The device is connected to the network WiFi, but no internet access;

In the event that you encounter one of the above malfunctions, before putting an end to the router, it is recommended that you carefully check and reconfigure the router and the device to which it is connected.

Troubleshooting the router

Before proceeding to the settings, you must first exclude hardware malfunctions of the device. To do this, follow these steps:

Step 1.

Connect LAN cable directly to your computer and check your internet connection. If there is Internet access, then the device is working properly and the problem lies in the router itself.

Step 2.

Connect LAN cable to the router and connect it with a second cable to the computer. If in this case Internet access has appeared, then the router is in working order and the reason for the wireless network lies in the settings of the WiFi.

Step 3.

Almost every router has a special button with which you can turn it on and off. WiFi. Click on it and make sure that the indicator light with the icon lights up on the device WiFi. It will signal that the sensor WiFi physically correct.

Step 4.

After you have established the health of the router, you need to make sure that the connected via WiFi device is correct. To do this, try connecting to the wireless network from another computer, phone, or tablet.

If another device recognizes the network and goes online, then the problem lies in the device that you connected earlier. Check if it is enabled WiFi and try again.

Troubleshooting Internet access via Wi-Fi

If the computer is connected to WiFi, but there is no Internet access, the problem is almost certainly an incorrect configuration of the operating system. If the computer was previously connected to the network of another provider, then, most likely, the previous IP address and DNS server address were saved in its settings. To reconfigure them, follow these steps:

Step 1.

On the taskbar in the right corner, find the icon for a wireless Internet connection, right-click on it and from the menu that appears, select the line " Network and Sharing Center».

Step 2.

In the pop-up window on the left, click on the line " Change adapter settings”, then right-click on the wireless connection icon and select “ Properties».

Step 3.

In the expanded window, you will need to find the line in the list " TCP/IPv4 protocol”, right-click on it and also select the line “ Properties».

Step 4.

The network card settings will open in front of you. In this window, you can manually enter IP and addresses DNS servers. However, for the correct operation of the wireless connection, it is recommended to set markers opposite the lines " Obtain an IP address automatically" and " Obtain DNS Server Address Automatically».

After selecting the items, press the button twice OK» to complete the setup and restart your computer. After the reboot, try to connect to the Internet using WiFi.

Setting up a Wi-Fi transmission channel through the router interface

In theory, one of the above methods of solving the problem should have worked. However, if this did not happen, then the last option remains.

All routers distribute WiFi through special channels, the number of which can reach 13 or more. As a rule, the default router settings are set to automatically search for the most suitable channel. In the event that the channel used is the same as the channel of your neighbors, Wi-Fi may experience disruptions. To change the channel manually, follow these steps:

Step 1.

Turn your router upside down and examine the contents of the sticker on the back of it. There must be indicated IP address to access the settings, as well as the login and password to enter them.

Figure 1. Setting up a Wi-Fi transmission channel through the router interface

Step 2.

Open any browser and enter the same one in the address bar IP, which is listed on the back of the device. Don't forget to put a dot at the end.
After going to the specified address, the login page for the router settings will open in front of you. Enter your username and password in the appropriate fields, which are written on the sticker, and log in.

Step 3.

Next, go to the " Wireless connection” and find the item “ Settings».
On the right side there is a line " Channel" which has the status " Auto».

Step 4.

Click on the arrow to open the drop-down list and select one of the available channels in it. Next click " Save».
The router will go to reboot. After processing all the new settings, you can try to connect to the Internet using WiFi. The problem must be solved.

IMPORTANT: The router settings interface depends on its manufacturer and model. The article shows an example of a router TP Link. However, all interfaces are similar to each other and have similar section names. If you want to learn more about the interface of your device, go to the official website of your provider and view information on routers.

VIDEO: The router does not distribute the Internet via Wi-Fi. What to do?

The possibilities of modern phones go far beyond voice communication. With no less success, they can be used to store and edit files and, of course, to connect to the global network. Since mobile standards are most often limited by providers, owners of gadgets based on Android and iOS most often use Wi-Fi technology to connect to the Internet. But in itself, the presence of a Wi-Fi module in a mobile device does not guarantee a connection to the network.

It happens that the phone does not connect to Wi-Fi, giving errors or notifying the user that the connection is impossible. Most often this happens due to a failure or incorrect settings of the device itself, but the same results can be caused by incorrect configuration of the router, modification of system files, installation of custom firmware, mismatch of communication standards, virus infection and, in rare cases, failure of the Wi-Fi module. . So, let's try to analyze in more detail why the phone does not connect to Wi-Fi and how to fix it.

Wrong password entry, temporary failure

This error is usually thrown when a Wi-Fi network cannot recognize the device connected to it. The reason is most often banal - the user makes a mistake when entering a password and, as a result, receives a corresponding message.

Please check that your password is correct and try to connect again. Also note the name of the network. The Wi-Fi module on your phone detects not only your network, but also other access points that may have similar names, such as mydoms and mydons. Make sure you are connecting to your network and not to your neighbor's network.

If up to this point there were no problems with authentication, first try restarting your smartphone and the router itself, perhaps there was some kind of temporary failure. Is your phone still unable to connect to the Wi-Fi network? Delete the saved network in the WLAN settings and try to reconnect.

The example discussed above is the simplest, but more often everything is a little more complicated, being associated with incorrect settings on the router itself.

Router settings

You connect to the network, but the phone does not connect to Wi-Fi, it says WPA2 or WPA is saved. After a few seconds, the message "Authentication failed" appears. If the password is correct, there is most likely something wrong with the router's security settings. It may be that the phone says “Saved”, but the connection is still not established. Getting into the router settings is easy, you just need to go to the internal address in the browser 192.168.0.1 or 192.168.1.1 . It is more difficult to deal with its interface, since it can differ significantly in different models of routers.

The default login and password is used to log in. admin/admin(look at the bottom of the case). Before making any changes to the router settings, remove the network from the phone, or at least disconnect. It is also advisable to create a backup copy of the router settings - if you suddenly get confused or do something wrong, you can always recover. After making changes to the settings of the router, it also requires a reboot.

Region

Now a little more about setting up an access point. First, try changing the region.

In the settings, this option is located in the section Wi-Fi - Advanced Settings, c - on the "Wireless" tab. In other models, it may be located in a different place. In short, you need to first study the interface of your router. In the regional settings, the country in which you live should be selected, although this is not critical. Save your settings and reconnect.

Network mode

A much more important setting that can prevent the gadget from connecting to Wi-Fi is the mode of operation of the wireless network. This is perhaps the main reason for an authentication error when connecting to Wi-Fi on a phone that may not support the current mode. There can be several modes: B, G, N, etc. If you have B / G / N mixed, install it, otherwise you can try to experiment by choosing one or the other mode. Pay attention also to the channel. It must be auto.

Security Options

Find the security section in your router settings and try playing around with the settings. It is desirable that network authentication be set to WPA / WPA or WPA-PSK (if there is mixed, enable it), encryption is AES, the key contains only Latin characters, only numbers, or both.

After changing the settings of the router, we reboot it, we establish the connection on the phone again. Unfortunately, the two methods described above can cause problems with connecting other devices, such as a laptop or TV, if they do not support the changed settings, so everything is not so simple here. If the password has been changed, in any case, it will also have to be changed on other devices.

Channel Width

It is highly unlikely that this will solve the problem, but just in case, you can try changing the bandwidth of the Wi-Fi network. In D-Link routers, look for the setting in the subsection Wi-Fi - Advanced Settings, in TP-Link - Wireless Settings - Channel Width. There are usually several available options: 20MHz, 40MHz, Auto and others.

Filtering by MAC address

Each electronic device has its own unique identifier - MAC address. Find the MAC filter subsection in the router settings and make sure that filtering is disabled.

If it is enabled, determine the MAC address of your smartphone, check the settings in the router and, if necessary, exclude the phone from the “black” list or, conversely, add it to the “white” one.

Phone stuck on getting IP address

Another common problem is the device is stuck at the stage of obtaining an IP address. The phone does not connect to Wi-Fi, writes "Obtaining an IP address", and this message can be displayed for hours. The cause of the problem, again, may be hidden either in the settings of the mobile device or the router. The latter is indicated by problems with connecting to Wi-Fi and other devices. The DHCP server is responsible for distributing IP addresses to devices, changing the address pool and the router itself in the router. If it is disabled, your device will never receive an IP address.

Is DHCP enabled?

Let's check the operation of DHCP. Different router models have different locations for this setting. In TP-Link, you need to look for it in the Local Area Network or LAN section, in D-Link it is usually located in the subsection Network - LAN.

The mode must be set to "Allow". Instead of a drop-down menu in the router settings, radio buttons "Enable" and "Disable" can be used. Here, we believe, everything is also clear.

Static IP

You can solve the problem with "eternal" obtaining an IP address by setting a static IP in the advanced connection settings of your device.

To do this, click on your connection in the list of networks, select Change network - Advanced settings - DHCP - Custom(In earlier versions of Android, you will need to check the "Static" box).

In the panel that opens, enter the IP address 192.168.X.YYY into the appropriate fields, where X is 1 or 0, it depends on the address by which you access the router settings (you can try both options), and YYY is any number from 0 up to 255.

The gateway must match the address of your router, leave the prefix length by default, do not touch DNS 1 (8.8.8.8) and DNS 2 (8.8.4.4). If you have other data instead of those indicated in brackets, also do not change them - they are given by your provider. The exception is DNS 2, which can be left blank. If something is not clear or you doubt the correctness of data entry, it is better to contact your provider's support service - it is their direct responsibility to connect their customers' devices to the network.

Automatic error correction tools

If you encounter an authentication error when connecting to Wi-Fi on Android, but you have mobile Internet, install the application from the Google Play Store Android WiFi Fixer. This utility is similar to the Windows connection troubleshooter and is designed to find and automatically fix Wi-Fi connection errors on Android mobile devices. When launched, the application checks all network settings and tries to connect to Wi-Fi bypassing.

Other reasons

The above examples of problems and how to fix them are the most common. In fact, there may be more reasons. Why won't my smartphone connect to Wi-Fi? You may have installed an unfinished proxy server program, caught some kind of virus, rooted the device, changed the firmware, etc. Here you need to look at the circumstances. There have been instances when the wireless connection was blocked by anti-virus programs.

In general, if the connection is lost after making some changes, most likely the reason is in them. If all else fails, reset the device to factory settings, remembering to back up important applications and data beforehand.

Well, the most unpleasant thing that can happen is the failure of the Wi-Fi adapter. In this case, not only yours, but also other wireless networks will not be detected. There is nothing to do here, you will have to carry your gadget to a service center.

One of the most common situations that I have to deal with in my practice is when the user has the Internet connected, but does not work. Why is this happening?!
The first thing to start looking for a solution to the problem is to reboot all devices associated with Internet access - a router, a computer, etc. Very often this is the result of a small glitch in the operation of one of them and is solved by a simple restart. If it doesn't help, read on!

So, your Internet is not working. How are you connected to it? As a rule, in most cases, the connection is organized through a Wi-Fi router, then see if the Internet access indicator is on or not. For example, on D-Link routers it is made in the form of a globe, on most devices it is simply signed as Internet.

Does not burn? Check the router settings and, if everything is in order, call the technical support of your provider.
But if the indicator glows friendly, then the connection is successful. Check access from other devices - from a tablet, phone or laptop. So you can find out from which side it is worth looking for the cause of the problem. Such cases, when the router connects to the global web and does not distribute the Internet to connected devices, happens once in a thousand. Usually they are associated with a malfunction in its operation and are treated by resetting the settings to the factory settings, followed by a complete reconfiguration. More often, it happens that there is no access from only one of the computers, while everything works fine for others. Then you need to look for the "root of evil" already on it.

If you are connected to the mobile Internet via a USB modem or WiFi module connected to a USB port, then try disconnecting it and reconnecting it. Does not help - switch the gadget to a nearby free port. Windows will reinstall the drivers and you can check again whether access has been granted or not.

Internet Connection Diagnostics in Windows 10

If the Internet is connected on your computer or laptop but does not work and you are sure that the reason lies in the wrong settings, then you should perform a few simple operations. Let's start by pinging some popular site. To do this, press the key combination Win + R to open the Run window:

In the "Open" line, type the command cmd. Click on the "OK" button to open the command line window. We select a command:

ping yandex.ru

If you don't like Yandex, you can specify Google instead. Press the "Enter" key and see the result. If everything is in order, then you will receive something like this response from the server:

If you receive this response:

Then we type another command:

Ping 77.88.8.8

This is the IP address of the public DNS server from Yandex, which is always available. Alternatively, you can ping the server from Google - 8.8.8.8. If the PC has access to the external network, then the response should be:

If the node pings by IP, but the sites do not open, then usually this indicates that the Internet is connected but does not work due to the fact that the DNS server address is not registered (or incorrectly registered) in the network card settings. How to do this, I will tell below.

If you see this response:

Then it’s worth checking if the router is available. To do this, it also needs to be pinged. You can see what IP address is used on it on a sticker, usually located at the bottom of the case. Usually it is either or . I have a D-Link router and it uses the second option:

If the router pings, but the node is not on the Internet, then the reason is most likely again in the router or in its settings.
But if the router is not available, this is a reason to delve into the network adapter settings on the computer. But before that, try disabling the antivirus and firewall, as very often they are the cause of most network problems.

It did not help and the Internet is still connected but does not work ?! Well, then again press the key combination Win + R so that the "Run" window appears and enter the command ncpa.cpl.
If everything was done correctly, then the Windows 10 network connections window should appear:

Right-click on the connection icon and select "Properties" from the menu. In the window that appears, double-click on the line "IP version 4 (TCP / IPv4)" to get into the protocol parameters:

Here we try to set the automatic receipt of addresses and again check the output to the global web.
Still not working? Then check the box "Use the following addresses":

You need to register an IP address from the subnet of your router. If it has an IP of 192.168.0.1, then set the computer to 192.168.0.2. If the router uses 192.168.1.1, then the PC will have 192.168.1.2. Mask 255.255.255.0. As the gateway, you must specify the address of the router. Register it as your preferred DNS server. You can specify an alternative DNS server from Yandex 77.88.8.8 or from Google - 8.8.8.8.

As a rule, after that access to the Internet appears. If none of the tips helped you, then I'm afraid that you need to call a professional specialist who can determine the cause of the problem and be able to fix it. Good luck to all!

Hello everyone, I haven't written anything for two whole days. And so today I will tell you why wifi is connected on the tablet and there is no Internet. Due to the fact that many of the tablets used are based on the popular Android OS, I will talk specifically about solving problems with such devices.

The problem that tablet lovers face when working with wireless Internet is the display of the "Obtaining an IP address" line. The operation of the gadget at this stage stops, and is not restored in the future. In fact, there are a couple of methods to solve the above problem, one of them should definitely help.

Change the name of the Wi-Fi network to any other that includes only English letters.
Reboot the router (this trivial method is often the most effective).
Change the type of data encryption (in the same place as the name of the wireless network, you need to change the type of protection to another).

For the entered settings to be applied, modem needs to be rebooted.

Preparatory process

Today I have everything, I hope you now know why wifi is connected on the tablet and there is no Internet. I want to ask you something else, if something doesn’t work out for you, write about it in the comments. Also, I will not refuse if, as a token of gratitude, like this article. I wish you all only positive emotions and good health.

With Uv. Evgeny Kryzhanovsky

Routers and access points with Wi-Fi have been an integral attribute of home and mobile Internet users for 10 years now. Once the speed of the Wi-Fi network can be greatly reduced, and sometimes the wireless connection disappears completely and for a long time.

The main causes of disruption of the Wi-Fi network

Problems with wireless Internet access can be due to various reasons: router failures, incorrect computer or smartphone settings, interference from nearby equipment, etc. Viruses and even hackers can disrupt work. In all cases, you need to identify the cause of the malfunction and try to eliminate it - first on your own, and if it doesn’t work out, then by contacting professional computer scientists.

Wi-Fi network is visible to devices, but they do not connect to it

There are several reasons why there may not be a connection to a Wi-Fi network.

Wi-Fi network not visible to devices

There are several reasons why a Wi-Fi network is not visible from a gadget or PC.

Wi-Fi on PC or tablet not working after reinstalling Windows

There are several reasons - from hardware to software.

Video: Wi-Fi not working after Windows 10 update

Laptop or tablet is connected to Wi-Fi, but there is no Internet

The reasons are related to the fact that there is no Internet access on the router.

Internet via Wi-Fi is available, but turns off by itself

There may also be several reasons.

Poor internet connection quality. If the provider has an unreliable communication channel or, in the battle for the first place in the list of the most popular operators, it went too far with the number of clients, the speed of individual users will be very low, the connection will often reconnect due to equipment overload, and incoming traffic will hang. Previously, cellular providers suffered from this - at the initial stages of development of the 2G / 3G / 4G coverage area, demand in the conditions of a precipitous decline in the price of 1 MB of traffic was far ahead of the construction and launch of new network facilities.
Hangup of the RAM of the router (overloading the data buffer). Restarting it will help.
The device has overheated - in any modern technology there is protection against overheating of microcircuits. Both the CPU / RAM of the router or access point, as well as any of its microcontrollers that process incoming / outgoing data via LAN or Wi-Fi, can overheat. It is advisable to turn off the router for at least a few minutes.

In the event of a poor 3G / 4G signal and high Internet speed, the 4G modem used with the router may also overheat at the same time. Users of Android smartphones and tablets (Yota subscribers), who distributed up to 40 GB every day via Wi-Fi (in the 2000s, these were Nokia and Motorola mobile phones connected via cable or Bluetooth), talk about cases when the device heated up like a kettle and disconnected every hour or two downloading / distributing torrents on a PC. The same thing happens with routers.

Wi-Fi not working due to firmware glitches and viruses

No matter how simple, friendly and secure the firmware (firmware) of the router is, the router itself is not protected from malfunctions and viruses. Viral technologies disrupted Apple, Android and Symbian gadgets. The virus code infiltrated ATMs, ATMs and access control systems at protected sites with Internet access, disabled the firmware in USB modems. Routers are also not insured - neither purely wireless ones from Beeline or Yota, nor home ZyXEL and TP-Link, nor Cisco access points, nor purely cable equipment used at facilities where any wireless element is prohibited by security rules.

Software failures can occur both due to inept flashing (through ignorance or accident, the power is reset at the time of updating the firmware in the flash memory of the router), or wear and tear of the flash memory chip itself (it’s impossible to even enter the router settings - underloading of web pages interface in the browser).

Virus activity is expressed in reprogramming the router settings: changing IP DNS to the values of a malicious server, substituting primitive passwords or turning off Wi-Fi security settings, switching wired protocols and cellular networks, etc. To fix this, do the following.

Sometimes a virus changes the firmware file just before it is loaded into the router. The solution is to remove viruses from the PC, using all means up to formatting the drive (of course, transferring valuable data to other media before that) and download the official firmware version again from the manufacturer's website.

Slow internet speed over Wi-Fi

The reasons are related both to the quality of network access and to the Wi-Fi connection parameters.

The last point requires clarification. The fact is that the Wi-Fi speed is switched by the router and the gadget automatically. Even if you forcibly turn on the maximum (802.11n or 150 Mbps), then moving into the next room, you may lose your Internet connection - incoming and outgoing traffic will “freeze”, sites will not open and instant messengers will stop working, even simple ones like ICQ , because lower-level speeds (802.11g, or 54 Mbps) will not be enabled.
