The wireless connection is connected without access to the Internet. Wi-Fi is connected, but the Internet does not work on Android. Problems with DHCP

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 unavailable or 404 Not found. Chrome still writes in such cases. The same applies to other software - all kinds of programs that use an 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 Wi-Fi settings of your router, computer, or phone, check the following points. This can 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 network?

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

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 indeed “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 . At the same time, the local network and Wi-Fi work normally, but there is no access to the Internet. 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 you still can't connect to the Internet through an active Wi-Fi connection, there's another option: set up a 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.

Sometimes your system shows that e.g. laptop connected to Wi-Fi, but no internet. There are several reasons for this problem.

In the worst case, it could simply be a faulty cable, and sometimes the problem could be with the system configuration. We have compiled a list of possible fixes for this issue.

The first possible solution is to reboot the OS and modem/router.

Reboot the OS: save all open documents on the system and close all open programs, if any. Click on the Windows icon and click the icon Power. You have 3 options. Click the Restart button. When you do this, your system will shut down and then reboot via the boot disk.

Reboot your router/modem: Open your router's web interface and click the reboot button. You can also do this using the router's physical power button, or simply unplug the power from the outlet and plug it back in.

This usually solves most WiFi problems. If the problem still persists, move on to the next solution.

# Reset WIFI settings

Every time we connect to any new Wi-Fi network, it is saved in the profile list. Over time, the list becomes larger and sometimes interferes with the proper functioning of Wi-Fi. Deleting old saved networks will help you fix this problem. Here's how you can fix the problem: The computer is connected to Wi-Fi but there is no internet:

In the lower right corner of your system, you will find a " Net"(this is the icon that shows the Wi-Fi symbol).
Clicking on it will open a small notification window in which you will see all Wi-Fi connections. Here you will find settingsnetwork and Internet .
Click Network & Internet Settings. A new window will open with various Internet settings.
On the left side you will find the Wi-Fi icon. You need to click on this icon, which will open the settings window.
Here click " Managing known networks" .
You will get a list of different networks you have used previously along with your current one.
Click on the old network. You will see a button "forget«
This will delete the old profile. Be sure to do this for all saved WIFI networks.

Try reconnecting to your WIFI network and checking for the problem.

# Fix by disabling antivirus software

Wi-Fi is connected but there is no Internet access? As the next solution, you need to disable the antivirus software running on your computer. If you are using third-party antivirus software, there is a chance that it is blocking your Wi-Fi connection. Disabling protection may help restore the connection.

Let's say for example, if you have Anti-Virus installed on your system, you can disable it by following these steps:

On the Windows taskbar, you will see a small triangle that, when clicked, will open in the notification area.
Right-click on the Antivirus icon.
You will see several options for temporarily and permanently disabling the antivirus. Select the appropriate one and check the WIFI operation.

# Fix for turning off Windows Firewall

Wi-Fi is connected, but there is no Internet on the laptop, what should I do? Windows OS comes with firewalls and they block the Internet connection on your system. Windows Firewall helps prevent users from accessing your computer's data and information. When the firewall detects a suspicious network, it blocks it from your system. If your The computer is connected to Wi-Fi, but there is no Internet access, follow these steps to disable Windows Firewall:

In the Search section, select Open control Panel".
Here you will find all the tools and software.
Find " Windows Firewall" and click on it.
On the far left you'll find a few more options - click " Turn Windows Defender Firewall on or off."
This will take you to a new page that will display a list of options - Public and Private Network Settings.
Click "Disable Defender Firewall (not recommended)" for the network you are working on.

Remember that a firewall protects you from malicious virus attacks. It would be better if you use this solution if you have a third-party antivirus firewall.

This will disable Windows Defender Firewall on your system. Try connecting to your network to see if the problem is resolved.

# TOdate/time adjustment

If your system shows the wrong date or time, Wi-Fi may not work correctly (writes connected to Wi-Fi but no internet).

Here's how you can correct your system's time and date:

At the bottom right of the system screen you will find the date and time.
Hover over it and right-click to expand the options.
You need to select " Set date/time" from the specified options.
A new window will open.
On the left side, among the displayed options, click " Date and time».
In this option you can disable the option "Set time automatically"
If you enable this setting, the system date and time will be set automatically according to the time zone in which you are located.
You can also do this manually if the setting does not change automatically.

After this, you can try connecting to Wi-Fi. If you are still facing the same problem, you need to take help from Windows troubleshooters.

# Fix using Windows Troubleshooter

What to do if you are connected to Wi-Fi but there is no Internet?

Windows has the ability to fix online problems using a troubleshooter. It only takes one click and all Internet related problems will be fixed. Follow these steps to access troubleshooting tools:

Open Control Panel. You can open it by typing "Control Panel" in the search window.
Here you will find all the control panel elements. Find the application on this page "Troubleshooting" and click on it.
Since we are dealing with an internet issue here, you need to click " Network and Internet".
Your system will look for the problem and fix it if there is one.
The process will take some time.

If this didn't work for you, we can move on to the next solution to the problem.

# DNS flush

To complete this process, follow these steps:

Right-click the Start icon on your system
From the list of options, select " Command line". You can also open Command Prompt by simply typing "Command Prompt" in the Search box.
You will be taken to a Windows command line application.
You need to type "ipconfig /flushdns" and press Enter.

Clearing DNS helps solve the internet problem if there is one.

# Change IP configuration to "Obtain an IP address automatically"

Why is there no internet when the laptop is connected to Wi-Fi? If Wi-Fi does not have the proper IP configuration, it will not work.

You need to enable automatic acquisition of an IP address and then try to connect to the Internet. You can do this using the following steps:

Go to your system's control panel. You can write "Control Panel" in the search bar.
Find here "Network and Sharing Center" and click on it to get more options.
On the right side, you will find "Change adapter settings".
This will show you the network connections available on your computer.
Since you have a problem with Wi-Fi, you need to right-click on the WIFI network and select "Properties".
In the list of options you need to select "Internet Protocol 4 (TCP/IPv4)" and press " Properties" .
Another pop-up window will appear where you will need to select "Obtain an IP address automatically" And "Obtain DNS server address automatically."
Once you have made your selection, click " OK", and then " Close" .

# Fix for updating WIFI drivers

Why is Wi-Fi connected, but there is no access to the Internet? As a final solution you can try updating the Wi-Fi drivers on your system to fix the problems. Follow the step-by-step guide to complete the process:

Right-click on the Start button and select " Device Manager" .
In the list of devices, find Network Adapters and double click on it to see more options.
You will get a list of network adapter names.
Right-click on the WiFi network adapter you want to update and select "Update driver"
Choose "Automatic driver search"
Once finished, click Close.
If the system finds a new driver, it will automatically download and install it.
After updating the driver, go to the Start menu and click the Shutdown button to reboot the system

Once your system is connected to Wi-Fi, check if the problem is resolved.

Lost Internet connection is a pressing problem for any PC user. There can be many reasons for this, both hardware, for example, a broken cable, and software, for example, incorrect configuration of the router.

Most of the problems with connecting to the global network can be solved on your own, but the other part needs to be able to be correctly diagnosed so that when you contact technical support, you can give the specialists the most complete information about the malfunction. This article will help you understand the intricacies of these processes.

Signs of a Lost Connection

You can determine that there is no Internet connection by the following signs:

This is not a complete list of signs, but they are the most informative. The presence of any item means that there is a problem with the Internet connection.

Determining the cause

The first step in dealing with network access restrictions is to find the cause of the problem.

First of all, if you access the Internet through a router installed at home, you should check its functionality, namely:

When using Wi-Fi, you need to check the operation of your device's wireless network adapter by connecting another computer or mobile phone to the access point. If you use a special utility from your provider to connect to the Internet, you will need to reinstall it to check.

In cases where there is a connection, but there is no Internet, you will most likely have to contact the technical support service of the service provider, since this situation often arises when the cable is broken, the provider’s network equipment malfunctions, or access to the global network is blocked due to late payment.

Using standard tools

Windows 7 and other operating systems in the line have tools for automatically fixing network problems. To access them, right-click on the network connection icon (lower right corner of the display) and select “Connection diagnostics”. After this, the process of checking and correcting connection errors will begin, and then a report on the results will be displayed on the screen.

If the previous procedure did not help and you still do not have Internet, then you should check the connections between the computer, router and provider cable, then reboot the router and PC. This sequence of actions is also relevant if the network is accessed via a Wi-Fi router.

A more radical, but generally accessible method of restoring the router’s functionality is to reset its settings using a special pressed button on the case. It should be held for a few seconds, then the router will reboot to factory settings and will have to be reconfigured to work with your provider's network.

If you do not have access to information on how to perform this procedure, then if the router malfunctions, you should immediately contact the technical support of your Internet provider.

Changing the network connection method

If the modem does not work, you can try to connect your PC to the Internet directly. You need to connect the input cable directly to the computer’s network card and change the method of obtaining the IP address to automatic, for this:

Manual connection setup

If the procedure described above helps and the Internet appears, then perhaps the DHCP server is not enabled on your router and because of this there is no connection on the PC. This problem occurs especially often with new routers. It is quite possible to bypass it without configuring the settings of the modem itself. To do this, you need to manually register the IP address for the computer’s network card.

Registering the IP address - video instructions:

This is done in the same “Properties” dialog of the network adapter parameters. Gaining access to this window is described in the previous section of the article. Only now you need to put markers next to the “Use the following IP address” and “Use the following DNS server addresses” fields. In the IP address field, enter the value 192.168.1.2, in the mask line - 255.255.255.0, and enter 192.168.1.1 in the gateway. As DNS servers, you can specify public Google addresses - 8.8.8.8, 8.8.4.4 or Yandex - 77.88.8.8.

Changing the modem's IP address

Internet identification will not occur due to the same intranet IP addresses of the computer and router, so you need to be able to change this parameter in the modem settings. On common routers of the TP-LINK line, this operation is performed according to the following algorithm:

Changing the MAC address

The MAC address is a unique identifier for any device on the Internet, and when two computers with the same MAC are connected to the network, one of them will lose the connection. Problems can arise both because of the network card of the PC and because of the router address.

The algorithm for changing this parameter in the router depends on its brand. So for an ASUS modem you need to go into its settings through a browser, open the “IPConfig” tab and click on the “WAN&LAN” section. Then you should find the MAC entry at the bottom of the dialog that opens and correct it. Then click on the “Apply” button and reboot the device.

Editing MAC on a computer running Windows 8 and 7 is possible using the following algorithm:

There should be no zeros in the first two positions of the address.
At the end of the sequence you should set 2, 6, A, B, E.

Video instructions for changing the Mac address on a PC:

If these conditions are not met, changes may not apply.

Contacting technical support

If after all your attempts to solve the problem yourself there is still no connection to your Internet, then you should contact your provider’s technical support by phone.

The required number is usually indicated in the contract for the provision of communication services and consultations are provided by all Internet traffic providers free of charge.

The practice of personally contacting Beeline and Rostelecom technical support shows that the call is answered fairly quickly and by fairly competent specialists who will help you sort out cables, connections, settings of the router and computer, and will tell you whether there are problems with the network on the linear part.

If, together with the operator, the problem cannot be solved, and you are still without access to the Internet, then the call will be directed to specialized engineers of the repair department.

Conclusion

Despite the fact that most problems can be solved on your own, contacting technical support will resolve the issue of what to do in the absence of the Internet in the shortest possible time and will save a lot of nerve cells that are so slowly restored. But if you like to configure and repair network equipment yourself, then the recommendations from this article will help you in this matter.

Users of computers and laptops running OS MS Windows 7 often encounter problems connecting to the Internet wirelessly. One of them is “Without Internet access” (connection is limited) via Wi-Fi technology. Everything seems to be configured and connected correctly, but you cannot access the network. On the connection icon located in the notification area, you see a yellow triangle with an exclamation mark.

This means that the network is active, but there is no Internet. Hover your cursor and you will see this message: “No Internet access.” “In other versions of the Windows operating system, the text will be slightly different: “Connection is restricted.” But changing the words does not change the meaning of this problem - there is no access to the network on your device.

And if you open the Network Sharing Center, you will most likely see the message “Unidentified network”. Many users face this problem and the solutions vary. If you have such an error on Windows 10 or 8, look for ways to resolve it in our separate article. And here we will show how to solve the problem “without access to the Internet” specifically for Windows version seven.

This error appears regardless of how the computer is connected to the Internet - via an Ethernet cable (directly or through a router) or using wireless access. But again, we have a separate article on Ethernet connections. And here we will consider only a wireless connection via a Wi-Fi network. Separate instructions for each connection are more convenient and understandable.

So, you have connected the Internet on your personal computer, desktop or laptop, via a wireless router. There is a connection, but the Internet itself is missing. Now we will try to fix the connection error by first finding the cause.

“No Internet access” over a wireless network in Windows 7: possible solutions

There are many solutions offered by both ordinary users and specialists. We have repeatedly encountered the problem of limited connection (no access to the network), and we can safely say that there are only three reasons: incorrectly configured router parameters or its malfunction, a failure on the side of the Internet provider and problems with the computer itself.

And if we find one of these three reasons, consider that the solution has been found.

So what you should do first thing:

You connect to the Internet by first setting up your router. And if, after connecting the device to the computer, you see the “not available” status and an exclamation mark on the antenna icon, then it’s all about incorrect router settings. The connection status indicates that the Internet is not available on this device. And we just found out the reason - the router is to blame. But what? First, you may have forgotten to configure your router to work with your service provider, or you may have set the wrong settings. Secondly, the router itself may not be configured correctly. Don't forget that each model has its own setup instructions. Thirdly, the router may simply be faulty. And to determine this, connect from a smartphone, for example. If the Internet does not work, the router is to blame.
Everything was fine with access to the Wi-Fi network, but after turning it on, restarting the computer, or while surfing, the connection disappeared. The very first thing to do is reboot both the router and computer. After reboot, connect the wireless Internet. In most cases, the problem of unexpected connection loss is solved.
A common reason for lack of access to the Internet after connecting a computer to a wireless Wi-Fi network is the banal cable. Yes, the one that goes from your network provider to your router. For example, there are cases when users do not fully connect it to the WAN connector or even confuse the connectors. And this happens when, instead of the WAN, due to an accidental error or ignorance, the cable is connected to the LAN connectors.
And it also happens that the reason for limited access to the network is even more trivial than in the case of connectors. You can spend several hours setting up your router, changing DNS addresses and puzzling over other reasons, and then remember that the personal account has run out of funds. Check your balance!
To effectively solve a problem, you need to determine the cause. As we wrote above, this could be a service provider (provider), the computer itself or the router (technical malfunction or incorrect settings when connecting). Finding the reason won't be difficult. First of all connect from another device(smartphone, tablet, ultrabook, PC) to this router. If the Internet works fine, look for the problem in the first device - a laptop or computer. But if not, we choose one of two options - the problem is in the provider (incorrectly configured, no connection) or in the router (technically faulty or parameters set incorrectly). To determine who exactly is at fault, connect the cable directly to the laptop, without a router. Well, here everything is simple: the Internet appeared - the router is to blame, it still doesn’t work - the problem is with the provider or, again, with the PC. To begin with, eliminate technical work on the provider’s side by calling the support service. Perhaps they are just carrying out preventive work. Another way to determine the cause of a limited Internet connection is to connect the router not via wireless technology, but using an Ethernet network cable.

So, we found the reason, now we’ll tell you how to fix everything.

Error “No Internet access” problem in the computer (laptop)

If you connected the router to a smartphone or other laptop, and the Internet on this device started working, then it is your computer that is to blame for the lack of access to the network. What can be done in this case? If possible, connect to another Internet, not Wi-Fi, and check if there is access. If the Internet suddenly disappears, remember what you did before. Maybe they enabled or disabled some Windows service, installed a new application or antivirus software, changed network settings, programs, etc., etc. Remember.

If you don’t remember any “sins”, let’s try the most popular solution first - change the DNS and IP parameters. For example, if you received addresses automatically, let's set them manually. And vice versa: if you registered them manually, we will change the option to receive them automatically. So, let's do the following.

Click on the antenna icon with a yellow sign to enter the “Network Management Center”.

There on the left there is an option for “Change adapter settings”. Click on it.

Find your wireless adapter and look at its “Properties”. Specifically, we need the “Internet Protocol Version 4 (TCP/IPv4)” parameters. See which items are ticked. If you get DNS and IP automatically, uncheck the box and specify static addresses. How to do this is shown in the picture below. But before you enter these parameters, make sure that the router’s IP matches (look at the address indicated on the router sticker). And specify the DNS addresses as follows: 8.8.4.4 , 8.8.8.8 .

If you opened the properties of “Internet Protocol Version 4 (TCP/IPv4)” and saw the specified parameters there, uncheck the static settings and set the address to be obtained automatically. That is, we try everything in reverse, or both in turn.

Enabling Federal Compliance Mode (FIPS)) - as a possible solution

Let's try to use the FIPS mode, and maybe it will help. Click on the antenna icon in the notification area, where the yellow triangle with an exclamation mark still pleases the eye.

To do this, go to the “Changing adapter settings” section (discussed above), there find your “problematic” “Wireless network” and open its “Properties”. A new window with tabs will open. Select Security and click on the button with Advanced settings. This is where the compatibility mode with FIPS, the American information processing standard, is turned on.

Check the box, click OK and reboot to activate the new settings.

What else can you come up with if none of the above, alas, works? Try to temporarily stop everything that interferes with the normal operation of the network or completely blocks it. It could be antivirus program, which first appeared on your computer, browser extensions installed after its installation, a firewall, etc.
You can also download and install a new driver for the adapter (downloaded from the official website of the manufacturer of your laptop or PC) or replace it with another one available in the system. Read about this in the article (it describes Windows 10, everything is the same on Windows 7).

Is the problem with the router or the Internet provider? How to fix this problem

Checking your provider is very simple - by connecting directly without a router (to a network cable). If you have Internet, call technical support. support. This could be anything - from equipment breakdown and preventative maintenance to simple non-payment of services. Therefore, before setting up a router, connecting a cable, etc., call your provider or go to their website.

If the router does not work on other devices either, check the correct cable connection and the settings themselves. See the picture and correct if yours is different:

If the cable was connected incorrectly, correct it and be sure to reboot the router.

If the internet still doesn't work, check if it's configured correctly. Your device may not be able to communicate with your service provider because you have configured the wrong parameters to connect to it. Open the router settings (this is the Internet or WAN tab, depending on the model) and set the correct connection used by the network service provider, as well as other settings. Each router model is configured differently. Look for the instructions for your device and configure it as needed. There is nothing complicated in the router settings even for an untrained user, if you follow the recommendations exactly.

These are the solutions to this common error in Windows 7. And if you correctly determine the cause of the problem (equipment failure, maintenance work at the provider, forgot to pay for services, or incorrect router settings, or computer malfunction), your wireless Internet will work.

If you have any other solutions, please share with us. And stay tuned for our updates, perhaps a new method will appear that will help solve the error with limited Wi-Fi connection of personal computers on the MS Windows 7 operating system.

The laptop is convenient because it has a built-in wifi module and you can do without pulling cables. But sometimes something unpleasant happens - the Internet on the laptop does not work. Let's figure out why and what to do in this situation.

Why does the Internet not work on a laptop?

There may be several reasons:

The first is that you forgot to pay for the Internet, and the provider has limited access. You need to go to your personal account (data from it must be specified in your agreement with the provider) and check the status of your account. There is a connection, but the data is transferred very slowly? Maybe your Internet speed was cut off for non-payment. Some companies do this. For example, Beeline or Rostelecom.

The second is interruptions on the part of the provider. If the account is in order and there is money, try to find out if there is a connection in principle. To do this, connect the network cable directly to the laptop and check if the Internet connection works. No? Check settings:

In the case when you do not have a cable connection at all (you recently changed the OS), then you need to create one. To do this you need:

Didn't help? Connect the cable to another laptop or PC. If the network appears, your network card may have burned out.
If the Internet does not work on another laptop via cable, call the technical support of your provider and find out the reason.

The third is poor coverage. When using Internet wifi with a 3G or 4G modem, or distributing it from a phone, there may be no network coverage at the point where you are and wifi does not work. For example, on the highway or outside the city. Check your mobile phone to see if there is a connection. Wireless Internet on a laptop will not work if the tower is located far away.

Fourth, you and your laptop have gone beyond the coverage of your wifi router. For example, you are outside the city in the country. The router is installed in the house, and you are trying to get wifi in the attic, under the roof. Be prepared that the roof will screen the connection or the distance is simply too long (in the case of a weak wifi router). Try moving closer to the router. The connection may begin to work.

Fifth, there are problems with the wifi router and for this reason the Internet on the laptop does not work via wifi. Try rebooting it. To do this, simply unplug its power supply, wait 30 seconds and plug it in again.

Sixth - the drivers have fallen off. Check if everything is ok with the software. To do this, go to Device Manager and check if there is a yellow exclamation mark on any network adapter. In the screenshot there is a red circle around where the yellow icon may appear.

If there is one, right-click and select the desired command.

Update your drivers.

Seventh – the network adapter is disabled. Hover your mouse pointer over it, right-click. If you see the “Enable” command, it means it was disabled for some reason.

Check all adapters.

Eighth – the wifi router settings have been lost. Enter the address http://192.168.1.1 in your browser (it may be different - look on the router itself) and enter your login and password (most often admin/admin). In the window, check all connection settings:

Connection type (taken from the contract or from technical support)
Network name
Encryption type (WPA2/PSK)
Virtual server mode activity virtual server mode - DCHP
Basically, one of these steps should help you gain access to the network or diagnose the problem.

Once again, we list the main steps if the Internet on a laptop does not work well via a wifi router or it has stopped working altogether:

Check your account - this is often the reason why the Internet on a laptop works slowly via wifi.
Reboot your wifi router - it might freeze.
Check your wifi router settings.
Check the integrity of the cable and plug it into the laptop and check the connection. If it has not been created before, create it. If a connection appears, the problem is in the router or wifi drivers on the laptop. Update them.
Try connecting the cable to another laptop or PC. If the connection works, your network card is disabled or burned out. If not, there is a problem on the provider's side.

Have a great day!
