Wi-Fi does not work: how to regain access to the wireless network. What to do when WiFi doesn't work


Hello, friends! If you don’t know what to do if the router doesn’t provide wifi, or if the Internet through wi-fi often breaks, then you’ve come to the right place. It is difficult to unequivocally answer why this happens because there are many reasons and it will not be possible to give a specific “recipe” for all malfunctions.

Let’s try to take a closer look at the main reasons.

  • There is Internet, but the device connected via wi-fi does not open sites
  • Wi-Fi network drops frequently
  • Connection problems
  • Internet via wi-fi does not work

Let's start with the basics, a wi-fi network operates on a specific channel. When we set the settings in the router, we set this parameter to “Auto”. This value sets the automatic search and the device selects the appropriate channel to use. This is where problems sometimes lie, so let’s try changing the parameters.

Where can I change the channel settings?

To change the parameters you need to go to the settings of your router, you can read how to do this. Now I will show you using my Asus router as an example. Everyone has different routers, but the principle, the names of the menus where changes need to be made, are more or less the same.

Let's go to "Wireless Network" in English, it will be "Wireless". We need "Channel" or "Channel". We point at it and there will be a drop-down menu, you will most likely have “Auto” set. Now try changing channels from this list one by one, save the changes, reboot the router and test for functionality.

Often they create configuration problems with DNS servers. These settings are specified manually or set automatically. Sometimes the settings go wrong or the servers are unstable. Try setting the settings as in the image.

If you purchased a laptop, you probably expected that you would use it to access the Internet. However, if your wifi does not work on your laptop, then you will not be able to connect to the network wirelessly. Therefore, if such a problem occurs, it is better to know in advance how to behave in order to quickly resolve the problem.

Checking the router

Before you begin to figure out why Wi-Fi is not working, you need to determine the source of the problem. Try connecting to the wireless network through any other device - smartphone, tablet, game console. If a connection is established on another device, then it is the laptop that has stopped working correctly.

If no device connects to the wireless network, then the cause of the problem should be looked for in the router. First, try to shorten the distance and remove all obstacles between the router and the laptop. Check that the wireless light on the router is on. If the light does not light, check your Wi-Fi settings:


What should I do if the above steps did not help, and the wireless connection still cannot be established or is slow? Call your provider to check if there are any problems on their end. If the operator reports that everything is fine, reset the router settings to factory settings, and then re-establish the connection, having first updated the router firmware.

Laptop problems

If you are convinced that the router is working normally, but there are no connections available on the laptop, then you should check whether the wifi module is turned on on the laptop. If the module is turned on, the indicator on the front panel of the laptop should light up. If it doesn't work, try turning on the Wi-Fi module manually using the function keys - e.g. Fn+F2. On different models The keyboard shortcut is different; Some models have a hardware wifi button. Carefully inspect the laptop case and find the button with the image of a Wi-Fi signal - click on it to turn on the adapter.

If the Fn button does not work, you can turn on the module using the switch found in the wireless connection settings. On Windows 10, you will need the Network and Internet section, which has a Wi-Fi tab.

If Windows 7 is installed on the laptop, then this method will not work. In this case, you will have to use an external keyboard with the Fn button (or the Windows on-screen keyboard).

Internet settings are reset after reinstalling Windows. If problems arise after installing the system, then you definitely need to check the adapter operating parameters. In addition to hardware enablement of the module, it is necessary to activate it in the system. On all versions Windows software inclusion is carried out according to one scheme:


If there is no wireless connection or it does not turn on, then you need to check whether the Wi-FI module driver is installed correctly. If the driver is not installed or does not work well, you will not be able to connect to the wireless network.

Checking the Wi-Fi driver

On all laptops, be it Lenovo, HP or any other brand, the Wi-Fi module should appear in the device manager, even if the driver is not installed correctly. To check the module driver wireless communication, you need to open “Device Manager”:

  1. Right-click on the “Computer” icon.
  2. Open the Manage tool.
  3. Select "Device Manager" on the left.

In the manager window, you need to open the “Network adapters” section and find the Wi-Fi adapter. There should be no warning signs near it. The properties should indicate that the device is working normally. If everything is installed correctly, but the Internet does not work, you need to try updating the driver.

To avoid compatibility issues, you need to know your laptop model. Armed with this information, go to the manufacturer’s website and download in the “Drivers” section software Wi-Fi adapter.

Other Possible Causes of the Problem

If connection problems occur after cleaning the laptop, then you need to check that the Wi-Fi module is installed in its place. Sometimes users who disassemble a laptop for the first time for cleaning make careless movements - for example, when removing the display, they touch the antenna of the wireless communication module. Therefore, if the problem occurs after cleaning the laptop, you should disassemble the device again and carefully check that the Wi-Fi module is in place and connected properly.

Sometimes resetting the BIOS helps. Why an error suddenly appears in the basic I/O system is difficult to say. But to exclude this option, go to the “Exit” tab in the BIOS and select “Load Setup Defaults”. Be sure to save your changes by pressing F10 and then "Y".

Another problem is when you cannot connect to the router, although there is a connection. When trying to set up a connection to an access point, the message “ Windows was unable to connect to...».

Typically, the cause of this error is a mismatch between the network parameters in the system and the router. Simply put, the network name or password has been changed in the router settings, and you are trying to connect using the old values. To resolve the problem, you need to remove the access point and update the list of connections.

These are the main reasons why a laptop does not connect to Wi-Fi. If none of the methods help, it makes sense to contact a service center - perhaps the reason for the incorrect operation of the Wi-Fi module is a hardware failure that you cannot fix on your own.

Routers and access points with Wi-Fi are an integral attribute of the home and mobile internet for 10 years now. One day, 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 reasons for disruption of the Wi-Fi network

Problems with wireless access to the Internet can be connected to for various reasons: router failures, incorrect computer or smartphone settings, interference from nearby equipment, etc. Viruses and even the actions of hackers can disrupt operation. In all cases, you need to identify the cause of the malfunction and try to eliminate it - first yourself, and if that doesn’t work, then turn to professional computer specialists.

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

There may be several reasons why there may be no connection to a Wi-Fi network.

Wi-Fi network is not visible to devices

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


Wi-Fi on PC or tablet does not work after reinstalling Windows

There are several reasons - from hardware to software.


Video: WI-Fi does not work after Windows 10 update

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

The reasons are due to the fact that the router does not have Internet access.


There is Internet via Wi-Fi, but it turns off on its own

There may also be several reasons.

  1. Inadequate Internet connection quality. If the provider has an unreliable communication channel or, in the battle for first place in the list of the most popular operators, has gone 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 freeze. Previously, cellular providers suffered from this - on initial stages development of the 2G/3G/4G coverage area, demand in the conditions of a collapse in the price of 1 MB of traffic far outstripped the construction and launch of new network facilities.
  2. The router's RAM freezes (data buffer overload). Restarting it will help.
  3. The device has overheated - at any time 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 data incoming/outgoing via LAN or Wi-Fi, can overheat. It is advisable to turn off the router for at least a few minutes.

If the 3G/4G signal is poor and the Internet speed is high, the 4G modem used with the router may also overheat. 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 got hot like a kettle and turned off every hour or two of downloading/distributing torrents on the PC. The same thing happens with routers.

Wi-Fi does not work 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. Virus technologies disrupted the operation of Apple, Android and Symbian gadgets. The virus code penetrated card machines, ATMs and access control systems at protected sites with the Internet, and disabled the firmware in USB modems. Routers are also not insured - neither purely wireless from Beeline or Yota, nor home ZyXEL and TP-Link, nor Cisco access points, nor purely cable equipment used in facilities where any wireless element is prohibited by security rules.

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

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


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

Slow Internet speed via Wi-Fi

The reasons are related to both the quality of network access and Wi-Fi communication 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 forcefully turn on the maximum (802.11n or 150 Mbit/s), then if you go into the next room, you may lose your connection to the Internet - incoming and outgoing traffic will freeze, websites will stop opening and messengers will stop working, even simple ones like ICQ , since the lower level speed (802.11g, or 54 Mbit/s) will not be enabled.

Different types of Wi-Fi networks support different data transfer rates

Check the auto speed selection in the router settings.

Advice for experimenters: without highly directional antennas and amplifiers, do not be located far from the router.

Other Wi-Fi errors and their solutions

Complete list of errors in Wi-Fi work is not limited to failures of the Wi-Fi repeater alone or problems on the provider’s side.

Network cable is not connected

The provider's network cable connected to the WAN socket may not be connected either to the router itself or to the entrance terminal. The reasons are as follows:

  • damaged cable wires;
  • broken RJ-45 connector retainer holding the cable in the LAN socket;
  • power outage (the terminal has no autonomous power supply);
  • malfunction of the LAN interface in the terminal and/or router (burnout of network equipment throughout the entire area from electrical interference, an accidentally dropped network wire, static discharge when touching materials or a lightning strike on external cables);
  • a faulty LAN network card in a PC or laptop (it happens that the adapter in Windows is detected as a working device, but the connection cannot be recognized);
  • viruses on PCs that overload Windows performance (displaying incorrect connection status or connecting with a delay of minutes or hours).

The connection is already in use or not configured

Error 651 indicates that the modem or dedicated one is already in use or has not been configured.

If the router is not configured or is already in use by other processes, error 651 is displayed

Your connection needs to be removed and reconfigured. The instructions are suitable for Windows 7/8/10 - working with the network connection setup wizard in latest versions I wasn’t enriched with anything special.


After clicking the “Connect” button, a connection to the Internet will be established. If the problem persists, contact your provider's support. In the worst case scenario, reinstalling Windows helps.

Infinitely obtaining an IP address from the router

Without receiving at least a temporary IP address from the DHCP IP address numbering range of the router, the gadget or PC will not be able to access the network. And this is typical not only for Wi-Fi connections - assigning an IP to a computer or mobile device laid down during the creation of TCP/IP.

If the device freezes at the stage of obtaining an IP address, you need to check the router settings

You need to check the router's IP settings.

Checking Wi-Fi settings

Do the following.


You may need to restart the router again.

Checking services and connections in Windows

Ensure that all services, addresses, and protocols critical to the network are enabled correctly. The following services are responsible for Windows networking capabilities:

  • DHCP client;
  • DNS client;
  • WLAN auto-configuration service;
  • web client;
  • IP auxiliary service;
  • routing and remote access;
  • server.

Do the following.


The connection of the router or cable modem to the network is broken

ADSL modems, popular in the 2000s, are being actively replaced by ONT modems (optical network terminal) - these devices support Internet speeds of up to 1 Gbit/s (using GPON technology), which differs from the throughput of an ADSL modem by 10 times. Already, Rostelecom and local providers provide Internet speeds of about 35–100 Mbit/s.

The reason for the decrease in Wi-Fi speed may be not only the reduced external speed at the cheapest available tariff, but also damage to the optical cables in the section ONT-modem - home rack-terminal - the nearest provider node. The LAN cable between the router and ONT modem may also be damaged.

The router in access point mode acts as a LAN/Wi-Fi distributor

The user can diagnose the entire subnet of the router (the router itself and its external cable). In case of damage to cables and equipment, including the ONT modem, telephone, IPTV set-top box and cables in the entrance, you should use the help of technical specialists from the same Rostelecom. This is also explained by the fact that if a twisted pair cable can be restored/replaced independently, then the subscriber simply may not have the tools to splice damaged fiber-optic lines.

Solving problems with Wi-Fi at home and at work is not particularly difficult. In many cases, the user will figure it out on his own. The help of a specialist is required only in cases where problems arise on the provider’s side.

WiFi broadband technology has become an integral part of people's lives. It allows you to solve routine tasks extremely quickly. That is why the question of why WiFi does not work on a laptop is very important. I would like to immediately note that there are many reasons why WiFi may not work on a laptop, and this article is not a panacea. However, in it you will find solutions to the most common problems, without calling a specialist.

Reasons why WiFi does not work

Before blaming the laptop, you should check the access point itself, since the router may be the cause of the wireless network not working.

First of all, you need to make sure that it is turned on and other devices, for example, a smartphone, tablet or other laptop, can connect to it. If everything is fine with the router, then move on.

Why WiFi doesn't work: Video

Checking and installing the network adapter driver

If the router is turned on, the network works, but WiFi still does not turn on on the laptop, you need to check the driver for the wireless adapter and network card. You can do this in Device Manager. You can open it as follows. Find the “My Computer” shortcut (on the desktop, in the Start menu, or in the file manager) and right-click on it. Select “Properties”. Next, in the left panel you need to find “Device Manager” and open it.

The menu that appears displays all the devices on the laptop, even if they do not have a driver installed. In this case, they will be indicated with an exclamation mark. We are interested in the “Network adapters” section. Open it by double-clicking and see if there is a device with an exclamation mark.

If there is one, then right-click on it and select “Delete”. We confirm the action. After that, if you have a disk with drivers, then insert it into the drive and install the necessary software. If there is no such disk, then you will need to go to the official website of the laptop manufacturer and download the necessary software for your model.

It is quite possible that the driver for the network equipment was previously installed, but at some point stopped working. Why might this happen? The most common cause is a virus attack. This may also be the result of turning off the device incorrectly, for example, by long pressing the power button. Sometimes such consequences occur after freezes or hardware errors.

After installing the drivers, we again check the ability to connect to the wireless network. It is worth noting that the above steps are performed regardless of the operating system version.

Reinstalling the WiFi driver in Windows: Video

Keyboard drivers

The network module drivers are ok, but the Wi-Fi adapter does not turn on, what should I do? Here you need to understand what is done using the keyboard. As a rule, this is a combination of the Fn keys + the WiFi enable button (marked with the corresponding icon). If the adapter does not turn on when you press these keys, you should install the driver on the keyboard.

There are cases when the driver is installed, most of the additional keys work, but you still cannot turn on the wireless adapter. In this case, it is recommended to install a special utility to manage the WiFi module. You can download it from the same source as the software.

Checking the wireless connection status

If everything is fine with the drivers, but WiFi still does not work, then you should check the status network connection. To do this, you need to open the network and sharing control panel by right-clicking on the network icon in the tray and go to “Change adapter settings.” Here we find the wireless network shortcut (the name may differ depending on the version of Windows).

If the shortcut gray this indicates that the connection is disconnected. You can enable it by right-clicking on the connection and selecting “Enable”. After this, the computer will automatically start searching for available networks.

You can also click "Diagnostics". This way, the system will automatically begin troubleshooting and troubleshooting problems related to the network adapters. It is worth noting that this procedure can be performed several times in a row, as it can help the second or even third time.

What to do if Wi-Fi on your laptop doesn’t work: Video

A few more reasons why the WiFi adapter may not work

Above were the main reasons why a wireless adapter may malfunction. Now you know what to do first if WiFi on your laptop does not work. However, it is worth noting that all of these are software reasons, which can be eliminated by simply installing new drivers, utilities, and also performing certain operations in Windows.

Sometimes there are hardware errors. What does this mean. Hardware failures occur directly with the board itself. In other words, this is physical damage to the network card. To fix such problems, you will have to disassemble the laptop. It is worth noting that some models are extremely easy to disassemble, however, there are also those that are quite difficult to disassemble on your own. It is necessary to warn that without certain knowledge in this area, it is not recommended to disassemble the laptop.

But still, in this article we will look at what physical damage can be. For example, if the device was under repair or you disassembled it yourself to clean the cooling system, it is quite possible that the antenna wires on the WiFi adapter are not connected. You can simply forget about them. In this case, the adapter works, but does not receive a signal, even if it is close to the source. The problem is resolved by simply connecting an antenna.

Also, the answer to the question why the Wi-Fi module does not work is simply overheating of the card and its failure. This can happen if the laptop is used in bed or placed on soft surfaces. The fact is that there are special holes on the bottom cover of the device through which cold air enters the system, cooling the boards.

It is not difficult to guess what will happen if these holes are blocked by long time. Another reason for overheating can be banal dust, which is drawn in by the fan and settles inside the laptop on absolutely all modules and elements of the laptop. It is for this reason that it is recommended to clean the device from dust at least once a year. Such cleaning will cost several times less than repairs.

If the WiFi adapter burns out, it cannot be repaired. All that remains is to replace it. You can check this in the device manager, since when it burns out, one or another element stops being displayed. In addition, if the module is displayed, but does not work, here you will be able to see an error indicating that it does not function. This, in turn, will allow you to find a solution to the problem.

Above we discussed the most common reasons why the Wi-Fi adapter does not work. They can be solved independently, without the help of specialists. However, if, after trying all these methods, you still cannot eliminate the cause of the problem, then it is recommended to contact a service center.

    Help me please. It's been three days now and nothing has worked!
    I have an HP Pavilion dv6-7053er laptop.
    In windows 7 everything worked until I bought bluetooth headphones. And for some reason I couldn’t find how to turn on bluetooth. I reinstalled Windows on Windows 10. But on the official website there was only firewood for 7K and 8K. Having downloaded everything that was there (after all, I download stuff for MY laptop) - I installed everything. I don’t understand bluetooth drivers, nor do I understand wi-fi. As a result, my wi-fi power button stopped lighting up and always lights up red. And when I pressed this button, my airplane mode turned on and off. I'm crazy. But that is not all. I accidentally (for some reason) tried to change the firmware on the touchpad after that... For some reason the firmware did not work. and now my touchpad doesn't work anywhere at all.
    I decided to demolish 10k and install 8.1 (I think 8.1 and 8 are no different in drivers). Put. Again the same problem is in front of me. Previously, after installing Windows. I had Wi-Fi, but not here. I installed what seems to me to be the correct drivers, complex names didn't touch it. It's good that there is Internet via wire. Now I will ask before going anywhere. I didn’t think that after 20 years of experience, I would stumble upon this wall of misunderstanding with technology, and even from the manufacturer HP (!!!).
    In general on this moment I have 3 problems (not counting crooked hands):
    1) The touch pad does not work. I installed the drivers from the website for my laptop. They stood up straight. I downloaded the firmware from there. But the firmware says that it does not see the driver on the touchpad and requires version 15 and higher (I installed 16).
    2) The Wi-Fi button does nothing at all. I didn’t find any wood for the button, I think wood for the touchpad will solve this problem
    3) The wireless network does not turn on at all. More precisely like that. In the adapter settings, the wireless network is colored, as the author of the video said, you can disable it, connect/disconnect. But when I click on the “network” button (about an hour), the wireless network slider is not active, it cannot be moved (you can move the wired network and turn on airplane mode).
    In the task manager in network adapters – qualcomm Atheros AR9285 802.1b|g|n WiFi adapter and Realtek PCIe GBE family controller. I didn't install Realtek at all. And Atheros was right after installing Windows. But I installed the driver from the website on top of it, and then after watching the video, I deleted it and installed it again. There is no result.
    In general, from the website I installed only these drivers: Drive for the chipset and Intel MEI, driver for the video card, Atheros driver. I didn't install anything else. Because I’m afraid it’s not clear how to remove the wood later. It’s clear when there are exclamation marks, but when everything is shown normally in the task manager, but something doesn’t work, I don’t know what to install or reinstall...

    Maxim 29.11.2015 16:44

    The touchpad was reanimated by pressing all the buttons in a row while holding the finger on the buttons. Despite the fact that the touchpad on the sensor has a power button, when double-clicked, it turns on and off... Now the touchpad is turned on and does not turn off, double tapping on the sensor does not turn off the touchpad and the light does not light up. The touchpad didn't get any traffic, but I think I'll find a solution myself. Moreover, in updates to Windows, the device for the touchpad is already downloaded.
    There is only one problem left - bluetooth. This problem is why I started changing Windows. He's stupidly gone. Everything is fine in Device Manager. But there is no bluetooth anywhere.

    Hello. Open the search and enter “Bluetooth”. If the system has an adapter and drivers installed, it will find several options. One of them will be “Bluetooth Settings”. Open the settings and configure the adapter. But, I would recommend that you return to the seven. The adapter itself is always enabled by default. It turns on with WiFi. And he switches off with her. The BT icon appears in the notification area (after installing the drivers) and always hangs there. Of course, you wrote a lot, but I couldn’t find any information on the matter. Is there BT in the equipment manager? Is it marked somehow? That is, perhaps there are some errors or failures in its work. Is there a Bluetooth connection in the Network and Sharing Center under “Change adapter settings”? Where did you get the drivers from? Drivers must match your operating system. In your case, it will not work in the top ten. In theory and in practice, many drivers from the eight are suitable for the ten, but still not all. Therefore, it is best to put a seven or eight. And you can configure everything in it. In general, my advice to you is to reinstall operating system. Place a Seven or Eight. Install new drivers, downloaded from the official website. After this, Bluetooth should appear in the notification area. Right-click on it and then configure it, add new equipment, and so on.

    Hi all! In general, I urgently need help.....I reinstalled Windows 7, then installed all the firewood, but when installing the firewood on wifi
    (Qualcomm Atheros Wireless drivers) starts swearing that the built-in wireless adapter is disabled or removed. what to do? Help!

    Bezprovodoff team 03/19/2016 10:40

    Hello. I would recommend that you reinstall the OS again. Most likely, the system was crooked and did not detect the WiFi adapter. You can also disassemble the laptop and disconnect the WiFi adapter, blow out and clean the contacts and connect it again. Sometimes contact is lost due to dirt (contacts may oxidize). Or you are installing the wrong driver (remember that sometimes during the download process there may be disconnections and the driver is not downloaded completely, which is why a variety of problems arise during the installation process). Therefore, before interrupting Windows and disassembling the laptop, try downloading the driver and monitor the boot process so that there are no disconnections or failures.

    Hello. The network adapter simply turns off automatically the moment WiFi starts working. If you connect a network cable to your PC, does the network work via cable? Should the indicator blink and the network start working? The problem is that the system automatically sees which network adapter is working, and the second one simply fades into the background. But, if you start using a network adapter (instead of WiFi), it should work normally when you connect the cable. Again, drivers must be installed for the network adapter, and drivers can only be installed when connected network cable. In general, you need to look and figure it out. It is possible that you will have to reinstall the OS (but this is a last resort).

    Hi all. The problem is this, at first the wifi started to turn off not for long and rarely (2 times a day), then it turned off every 5-7 minutes and had to be turned on through the device manager, later every 2 minutes, then it didn’t always help to turn it on through the manager, first from wi fi networks disappears only my network after 10 seconds all the others, and the icon changes as if there is no firewood, I went to the official HP office, downloaded the firewood, installed it, no use, when I connect to the Internet, 1 more network adapter appears in the Device Manager and a yellow sign, supposedly update me , I click on update - it says everything is OK, nothing needs to be updated...??? I think the adapter needs to be changed, tell me

    Bezprovodoff team 10/19/2016 22:15

    Hello. Updating drivers through Device Manager does not resolve the driver issue. The system always says that no update is required. Try this. First, download drivers for WiFi and other network adapters from the official HP website to your laptop. Let the installation files be on the hard drive; they will be needed later. Now, open the device manager, find the “Network adapters” folder. Remove from it everything you find there (I repeat, you need to download the drivers first). After this, open a command prompt with administrator rights and reset the network parameters and network cache. Here it is described in detail and shown how this is done - https://www.youtube.com/watch?v=T0vOyaSeY3Y. After this, restart your computer. Now install the previously downloaded drivers for network cards, including WiFi, and reboot the PC again. After this everything should work fine. If not, then change the Wi-Fi adapter.

    Guys, even though the search engine shows up your site, but there is no help here, delnava in v310-15isk, I’ve already tried all the wi-fi, all the wood is worth it, but the connection is found in about 40 minutes best case scenario and even if you want to, I’ve already looked through all the settings

Let's look at a problematic situation when the phone connects to Wi-Fi, but there is no Internet. It looks like this: next to the name of the wireless network it says “Connected”, but when you try to open any site in the browser an error is displayed Web-page is unavailable or 404 Not found. Chrome still writes in such cases. The same applies to other software - all kinds of programs that use the Internet connection for their work or at least check for updates when starting will also display an error connecting to their web server.

In this article, we will talk in detail about how to solve the Internet problem on your computer, phone or tablet. Read carefully, follow all the steps and you will definitely find the reason why you do not have an Internet connection when your Wi-Fi connection is working.

Collecting information about the problem

Before making any changes to the settings Wi-Fi router and, computer or phone, find out the following points. This may make it easier to find the reason for the lack of Internet or narrow down your search:

  • Is the Internet paid for and are the funds in the account running out?
  • Is there access to the Internet via wire from a desktop computer?
  • Is it possible to access the Internet via Wi-Fi from other devices that use the same Wi-Fi router?
  • does the Internet connection problem persist when connected to another Wi-Fi networks?

Depending on the answers to these questions, it may already become more or less clear to you what the problem most likely is. Eg:

  • if there is no Internet at all - neither via wires nor via Wi-Fi, then the reason may be either access blocking on the provider’s side or a malfunction of the router. Next, we check with the provider whether everything is in order with the line and the account, and then we check the functionality of the router.
  • if the Internet is available on the PC via wire, but not on any device via Wi-Fi, then the problem most likely lies in the wireless network settings of the router. The same conclusion can be drawn if the Internet appears and works without problems as soon as you connect to another Wi-Fi network from the same device
  • and if it turns out that all devices are in order, and only one does not have an Internet connection, then the problem is obviously in this “client”.

Wi-Fi is connected, but the Internet does not work. What to do?

So, if your Wi-Fi is truly “connected”, but there is no Internet (websites do not load, Skype and Viber do not connect, a yellow network icon is displayed on the laptop with the notification “No Internet access”), follow these steps to resolve the problem. The steps are listed taking into account the probability factor.

1. Reboot your router

Sometimes the inexplicable happens router failure . Wherein the local network and Wi-Fi work fine, but there is no Internet access. This can happen when the router operates for a very long time without reboots and when there are changes in the provider’s network. Just in case: it is written how to reboot D-Link remotely.

2. Reboot the device where there is no Internet connection (phone, laptop)

Sometimes on a smartphone (tablet, laptop) a certain failure (glitch), which can cause a similar problem. Visually, everything seems to be fine, but there is no Internet for no apparent reason. To eliminate such a failure, reboot the device.

3. Reconnect to the Wi-Fi network

This step is very important, despite its simplicity and obviousness at first glance. You need to forget the Wi-Fi network, and then connect to it again by entering the password (security key). This may resolve the issue and restore your internet connection, for example if network settings have been changed user or virus.

4. Set the correct date on your Android device

Invalid date may be causing an internet problem. In this case, the sites will open, but Antiviruses, Google Play Market, etc. may not work. .

5. Disable the proxy server

If a proxy server is enabled on your computer or Android device, you may also experience a situation where Wi-Fi is connected but there is no Internet. This problem usually occurs on Android.

6. Check the Internet connection settings on the router

Go to the WAN or Internet settings on the router. (). Check that you have specified correct connection parameters , such as:

  • type of connection with the provider (look in the contract or on the provider’s website);
  • login and password, if required (see the contract);
  • is the MAC address specified correctly (check in the contract. If you reset the router, you may have to go to the Internet provider’s office with your passport and contract and ask to register a new MAC address for the router’s WAN port).

If your provider uses a PPTP connection, and the settings on your router have gone wrong and now IPoE (dynamic IP) is selected instead of PPTP, then naturally the router will not be able to connect to the Internet. In this case, the sites will not open on any device.

7. Change the wireless channel

Wireless equipment that is located nearby and operates on adjacent channels can create interference to your router. Try changing the Wi-Fi channel.

It would be even better to first check which channels are freer. This can be done using the Android app or InSSIDer for Windows.

8. Install WPA2-PSK + AES encryption for your Wi-Fi network

The WPA2-PSK encryption algorithm is the most secure. And AES encryption provides high speed and security. Most devices, even not new ones, work successfully in WPA2-PSK mode with the AES algorithm.

Wi-Fi is connected, but the Internet does not work: other causes of the problem

Weak signal

If the distance from the client device to the router is too great, the following problem may also occur: the device has received an IP address, but there is no Internet. Therefore, you first need to check whether the Internet appears when approaching the router (if it is possible to get close). Then - if the problem is the distance - somehow try to reduce it. If the router is yours, place it in the middle of the house.

Some organizations provide free Wi-Fi, but in order to be allowed on the Internet, you need to launch a browser, enter a password, or go through some other authorization procedure. For example, indicate a phone number and enter a code from an SMS. It is better not to contact such networks and not to enter any information about yourself in order to avoid problems. It is much easier to find another access point without such nuances.

If you've done everything and still can't connect to the Internet through an active Wi-Fi connection, there's another option: set up static IP address. This method is not a solution in the full sense of the word, but in some cases it helps to bypass the problem and gain access to the Internet. To do this, on your smartphone, call up the properties of the connection to the Wi-Fi network, check the box Show advanced options and select Static IP:

I hope this guide helped you identify and fix your Internet connection problem and now all your devices are connected to the network, both wired and wireless. Please write questions and additions to the article in the comments.
