Unidentified network over local network. What to do when an unidentified network appears with the message “No access to the Internet. Network driver problems

Today I will look at a situation that users of operating systems often encounter Windows 7 And Windows 8. The essence of the problem is this: there is a connection to the network, but Network and Sharing Center writes that the Network without access to the Internet, there is about a clock next to the network icon in the tray Exclamation point. In fact, the Internet may even be accessible. There may be several reasons with different scenarios. Let's take a closer look at each of them.

But first things first, if you are connected via a modem, router or optical ONT terminal- I would advise reboot it. If, after rebooting the device, Internet access resumes, the problem is clearly in the router itself, its settings, or the provider’s network (this also happens). In this case, we reset the router with the reset button, configure it again and check. If still after some time a message appears that Network without Internet access- try another router to check.

1. WiFi network without Internet access

This is the most common situation. The reason for this problem is most often the following. The vast majority of users are not aware at all what is an IP address and believes that for Wi-Fi connection You just need to enter the network security key. In most cases, this may indeed be enough, but not always. If on WiFi router protocol disabled DHCP, then you can easily connect to the network, but here IP address your wireless adapter on your laptop, tablet or smartphone will not receive it. Accordingly, you will not have access to the Internet, although the network is actually connected, but only partially.
By the way, this is also possible with a wired connection - the cable was plugged in, but the address was not received.
What to do? Register the IP address manually. To register IP in Windows 7 or Windows 8 you need to do the following:
Let's go to Control Panel and click on the icon Network and Sharing Center:

In the window that opens, click on the link Change adapter settings. A list of network adapters will open. Right-click on the network adapter through which we connect to the router and select the menu item Properties:

The network card properties window will open. Select an item Internet Protocol Version 4 (TCP/IPv4) and double-click on it with the left mouse button. This is where you need it register IP address, netmask, gateway and DNS address:

For most routers (except D-Link) the following should be suitable:
IP address — 192.168.1.2
mask — 255.255.255.0
Gateway — 192.168.1.1
primary DNS — 192.168.1.1
secondary DNS — 8.8.8.8
For D-Link routers:
IP address — 192.168.0.2
mask — 255.255.255.0
Gateway — 192.168.0.1
primary DNS — 192.168.0.1
secondary DNS — 8.8.8.8

2. There is Internet access, but it still says Network without Internet access

This problem is most often occurs when a computer connects to the Internet via a proxy server . That is, there is access to the Internet, but it is not direct, but through a server.
In this case, you can do the following:
Press the button Start select an item Execute(or press the key combination Win+R ) and in the window that opens we write:
gpedit.msc
it will be revealed to you Local Group Policy Editor.
Local Computer Policy → Computer configuration → Administrative Templates → System → Internet Communication Management → Internet communication settings and enable the parameter:
« Disable active probing for the network connection status indicator «

In the PC IP address text field, you need to set the address of the router (router).

In the “Default gateway”, “DNS server” text field, enter the router’s internet protocol address (the same IP address of the router). At the end of everything, we confirm our actions by clicking on the “Ok” button.

Second way.

We need to go to the router settings interface and set the range of IP addresses assigned by the router automatically. Make sure that it does not include the PC IP address that we specified manually.

Type URL – 192.168.1.1 in your browser, log in and the router’s admin panel will open in front of you.

There we need to find “Local Network” and go into the DHPC server settings.

In the “Starting address of the IP address pool” item, enter an arbitrary address that follows the PC address that we set manually (192.168.1.2). Finally, click on the “Apply” button.

I entered the following numbers - 192.168.1.5. Now the router automatically sets addresses for each device, starting with it.

If you do not know the IP address of the router, then take a look at it. As a rule, the manufacturer indicates at the bottom all the data about the device, including the IP address.

Everyone faces this problem, and, unfortunately, this fate comes sooner or later. There is no need to be afraid, since in particular the problem can still be solved, although there can be a lot of reasons for it. And so, you can’t go to any website, but in the lower right corner it says “Without access to the Internet” or “without access to the network,” and you see a yellow triangle. Let's not beat around the bush, and let's look at all the possible solutions - let's start with the most popular ones.

HELP! Dear readers, you can always write your question or describe your problem below in the comments. And I will try to help you as much as I can.

How to fix - quick solution

What to do first? If Internet packets are distributed over wireless network Wi-Fi and it suddenly disappeared, then the router may have malfunctioned. This happens on old, already worn routers that have been working for more than one year. Our task is simply to reboot the device. This can be done in two ways:

1. We find the ON/OFF or ON/OFF button on the rear panel. Press once, wait 5 seconds and turn it on.
2. Unplug the power cord from the outlet and after 5 seconds plug it in again.

Sometimes a router is only needed to distribute a Wi-Fi network, and access to the World Wide Web is via a modem. So, just in case, reboot it too.

My old router glitched like this every 2-3 days. He was just old and his time had come to an end. Soon I bought a new one. So, if this problem occurs frequently, then purchase a new device.

Checking the physical connection

It doesn’t matter if you have a computer or a laptop, if the wire goes straight, then look at whether the light on the network card is blinking or on. Also make sure that the LAN port indicator light is on. Let me explain more clearly - almost every router has an indicator.

When you insert a wire into one of the LAN ports and data is being exchanged, the indicator lights up or blinks. The indicators are located on the front of the device. Take a look at the photo below - 1 LAN port is connected to the PC and works stably.

If the light does not light up when physically connected, then most likely the cable is broken. The box from under the router should contain a factory wire, you can safely use it.

Another problem is when the internet cable is plugged into the wrong place. Look back and see that the cable from the provider was in the Internet connector. A friend’s daughter once played with the router and stuck the wires into the wrong connectors and therefore there was no Internet. If the router does not light up at all, then there is a problem with the power supply, try turning it on.

The surest way is to screw the wires and see that they stand clearly in the port. One day my internet went out because the eye on the plastic end of the wire fell off, causing the wire to simply come off. In this case, good old matches will help. But it’s still better to re-crimp the end or change the cable.

Network settings

If you connect via Wi-Fi, the problem may lie elsewhere. In 20% of cases, the network settings on the PC do not allow you to access the Internet. The principle of changing the configuration is the same as on Windows 7, XP, 8, 10 and Vista.

1. You need to click on the yellow triangle in the lower corner, and then select "Network and Sharing Center."

1. Next, select from the left block - "Change adapter settings".
2. Typically, a desktop PC has one network card, while laptops have two connections: wireless and LAN. Make sure the connection you are using is turned on. When the configuration is disabled, it will be highlighted in gray. To enable it, right-click and “Enable”.
3. Right-click on the desired connection and then click on “Properties”.

1. Click once on "Internet Protocol Version 2(TCP/IPv4)". And then on properties.

1. Pay attention to the picture above. The settings include a permanent IP address. Also directly registered are the subnet mask and the main gateway (must be our router). Therefore, there are two options for network inoperability:
   1. If someone else is using the Internet, then most likely this IP address is already in use by another computer, phone or network printer.
   2. The second option is that the router is on a different subnet.
2. There is only one solution, just check the box next to it "Obtain an IP address automatically" And "Obtain DNS server address automatically".
3. We confirm the configuration and look at the result.
4. In case of further lack of network, go to settings again, check the box "Use the following DNS server addresses" and write:
   1. Preferred DNS Server: 8.8.8.8
   2. Alternate DNS Server: 8.8.4.4
5. Next, the Internet should connect. If this does not help immediately, then after changing the configuration, restart your computer or laptop.

Installing FIPS

1. If you have a laptop and connect via WiFi networks– click on it in the right corner of the desktop.
2. Then click "Properties".
3. Click on the second tab from the left with the name "Safety".

1. Click on the button at the very bottom - "Extra options".
2. Put a mark “Enable compatibility mode for this network with the Federal Information Processing Standard (FIPS)" and confirm the change . After this, reboot your computer or laptop.

Resetting DNS communication settings

1. Let's launch command line. To do this, enter cmd in the start menu in the search bar.
2. Right click and “Run as administrator”. If you just launch the console, no changes will be made.
3. Next, enter the commands one by one:
   1. ipconfig /flushdns
   2. netsh winsock reset
   3. netsh int ip reset c:\resetlog.txt.
4. Now we reboot the machine.

Software and faulty network card drivers

Drivers can break due to viruses or third party programs, which work with network protocols. It is very popular for Sich to use WPN programs that can install additional network connections.

1. Press WIN+R, enter ncpa.cpl and press OK.
2. See if there are any suspicious connections that weren't there before.
3. If they are, then turn them off by right-clicking - "Property" and press "Switch off".
4. After this, even if the Internet and network are working, you need to remove the conflicting program.
5. Let's go to Start.
6. Next, select "Control Panel" and go to the programs.

1. Set sort by installation date and see the latest installed programs. Sometimes the installation may take place in the background while downloading normal programs.
2. Remove suspicious software by right-clicking and "Delete".
3. Reboot the computer.
4. It’s not a fact that everything will start working, since the program could break the driver for the network card. The fastest way is to restore the system. To do this we go to “Start” – “All Programs” – “Accessories” – “System Tools”. Select " System Restore".
5. Select the earliest possible point and start the service. After rebooting, the system should display a successful recovery window. If you see a message that the system has not been restored, you will have to look for a driver on the Internet, download it, and then install it on your PC. If you still have a disk with drivers from motherboard, then you can install from there.

The system can break down not only from third-party software, but also from viruses. So be sure to install latest version antivirus and scan your entire computer for dangerous and suspicious software.

Provider

In 80% of cases, this problem lies on the shoulders of the provider. You should definitely call and find out what the problem is.

After dialing, they usually say that technical work is underway or there is a breakdown in the channel. But sometimes they may say that everything is fine with them. Ask a technical worker. services check the connection from the server to you.

If this doesn't help, ask which DNS is better to use. You already know how to change them from the chapters above. If all else fails, then the cable may have been cut off on your line at the entrance, then you will have to call a worker to your home to check the line.

Different subnets

Sometimes a problem with the Internet connection occurs because the computer and the network adapter are on different subnets. This often happens in offices when a new machine is connected to the subnet.

1. First, we need to find the IP address of the router. According to the standard, they are 192.168.1.1 or 192.168.0.1. I personally have 192.168.1.1.

NOTE! The standard address of the router can be found on the label under the device.

1. You need to go to the network settings and see what is there. In any Windows, press two WIN+R keys at the same time. Enter the ncpa.cpl command and click OK.

1. Next, you need to view the properties of the IPv4 connection.

1. Please note that the computer's IP address is 192.168.5.123. And the address of my router is 192.168.1.1. They are located in different subnets and do not see each other. My PC is located in the 5th subnet, and the router is in the 1st.
2. Next, it is best to set automatic detection of IP and DNS, as in the picture below.

Setting up the router

Once there was a case when children, playing with an interesting box, reset the router settings to factory settings, and then no one could understand what the problem was. Sometimes it happens that the settings themselves have gone wrong and need to be adjusted or corrected. The most important thing is to take and keep close to you the contract with your provider, which specifies the connection settings.

1. It's best to connect the router directly if this is not the case. Take a regular wire and plug one end into one of the LAN ports, and the other into the network card.
2. Now you need to go to the admin panel of the router. To do this, open any browser and enter the IP address of the router. According to the standard, this is usually either 192.168.1.1 or 192.168.0.1.

1. Enter your login and password. By factory standards, this is admin, admin, if you haven’t changed them. The instructions below will be slightly different. operating system router.

TP-Link

I’ll tell you using the example of the TP-Link Wireless N Router WR841N model, which is the most popular in the Russian Federation and the CIS countries.

1. In the left menu select "Net", and then press « WAN".

1. Click on the connection type and select the one that your provider uses: Static IP address, PPPoE, L2TP/L2TP, PPTP/PPTP, BigPont cable.
2. Next, depending on your choice, you need to enter data from the provider from the contract or by calling the hotline number in tech. support.
3. If you have difficulty with the settings, then click "Quick setup" in the left menu and simply follow the instructions.

ASUS

1. In the lower left menu select "Internet".
2. Select the connection type in
   1. Enter the settings. You can also click "Quick Internet settings."

   Other models

   The scheme is basically the same:

   1. In the main menu, find the “Internet” or “WAN” section and click on it.
   2. Select the connection type that your provider uses:
      1. Automatic IP detection– this connection is usually installed in the machine. Here we simply set this parameter and the Internet should appear.
      2. PPPoE– here you will need a login and password to access. You may need to specify a bound MAC address. If this is your PC, then click clone this parameter.
      3. Static IP– here you need to specify the external IP, subnet mask, default gateway and DNS server.
      4. L2TP or PPTP– indicate static connection data, login, password and DNS.
   3. We enter the settings from the contract.
   4. Don't forget to set up Wi-Fi.
   5. We apply them and reboot the router - turning it off and on.

   ADVICE! To know how to set up Internet and Wi-Fi for your model, just use the search on our website. To do this, enter the full name of your router and follow the instructions in the article. There is nothing complicated there and everything is written very clearly.

Recently, we have described a lot of solutions to various problems related to connecting to . Now it’s time to pay a little attention to the problems that you may encounter when using a cable Internet connection. Although various errors and difficulties arise here much less often, sometimes you still have to deal with incomprehensible problems.

In today's article we will get acquainted with the main problems and ways to solve them that appear when connecting a computer to the Internet via a router. We will consider the case specifically when connecting through this device. If you are connected via a cable network directly from the provider, then this is a little different and today we are not touching on this topic.

This type of connection is often used if you need to organize Wi-Fi network, but at the same time, there are desktop computers, you need to connect the Internet to them. And such computers usually do not have a wireless adapter. Of course, there is a way out of this situation without unnecessary wiring - you need to purchase a special wifi adapter, connected via USB.

Troubleshooting problems with connecting to the Internet via a network cable from a router

But for now we will take a closer look at the topic of our article. If, after connecting your computer with a cable to the router, the Internet does not appear, then you need to look at the following important questions:

• Try connecting another PC to the same cable. Will it work?
• Connect cable internet to your PC without a router. Will it work now?
• The LAN LED on the router should be lit.
• You need to look at the connection status by local network. What does it show? It may not show any signs of activity at all when the cable is connected. Or it can begin identifying the connection.

Depending on the answers to these questions, we will determine the cause of the problem.

The computer does not see the connected LAN cable

In this case, when connecting the network cable, no messages or activity appears from the latter. The network connections icon is crossed out in red, and if you hover over it, the message “No connection” will appear. Everything looks exactly the same as if the cable was not connected at all.

Here the problem can be hidden in three places: either in the router or computer, or the cause may be a damaged cable. First, let's check the health of the computer itself.

Connect the cable to it without a router, directly. If the network connection status has changed, then apparently the PC has nothing to do with it. Or you can check it the other way around by connecting the cable through the router to another PC.

If the computer continues not to see the cables connected to it, regardless of their sources, then most likely we have problems with the network card. If necessary, you can always purchase and install another one, especially since it is not expensive. But first, make sure that your computer actually has a network card driver. You can check this by going to Device Manager and expanding the list of network adapters. Make sure your card is there. Its name may differ from what is shown in the figure below.

In some cases, the network card may be displayed, but there will be a yellow exclamation mark next to it. This indicates that the network card may not work correctly. You need to try reinstalling the driver for this device. Download it from the manufacturer's official website and install it manually.

Sometimes you may encounter that the connector for connecting the network cable on the router is burnt out or somehow damaged. Routers often have several of these connectors, so try connecting the cable to others. Maybe everything will work.

The problem may also be in the router itself; this can be checked by connecting it to several different computers. If in all cases the connection to the Internet does not appear, then it is obvious that the culprit is the router. This may not necessarily be a physical malfunction, perhaps just something in the settings is messed up. Reset and restart it, then check again.

In this case, you need to be sure that the cable itself is in good condition. It can also break somewhere or have bad contact. You can look for another one and check it. But the problem may be related to the settings on the computer. In some cases, the local network may be disabled on the PC.

Here you need to go to the Network and Internet section through the Control Panel and open Network Connections. If the status “Disabled” appears under the local network connection icon, right-click on it and enable it.

Usually one of these recommendations will definitely help.

The network is constantly being identified, or it is not recognized at all

Now let's see what can be done if the computer notices the connection of the network cable, but still cannot connect to the Internet. For example, we connected the cable and the network status “Identification” appeared. Everything seems to be cool and the network should appear soon! But time passes and nothing changes.

Another case is when the computer does not recognize the network and displays the corresponding status.

Typically, such errors are directly related to obtaining an IP address. Automatic detection of network settings may be disabled on the computer, or a specific static IP address may be recorded instead. For example, it may remain from a previous connection. But for the router it is not correct and you will not be able to establish a connection to the Internet. DHCP may not work on the router itself, which automatically issues addresses to all devices. Again, you need to go into settings and enable this feature, or manually enter all the necessary addresses on your computer.

To enable automatic detection of IP and DNS addresses, you need to go to the Control Panel and open the Networks and Internet section there. Next we go to network connections. There is another way to get there, do it as shown in the picture below.

Next, right-click on Local Network Connection and open its properties. Then follow the steps shown in this figure.

Unplug your network cable from your computer and connect it again. After this, the Internet should start working normally.

By following the same paths, in the same settings, you can manually specify IP addresses. Only in this case, activate Use the following IP. We determine which address needs to be entered using the address at which the router settings are available. For example, the router settings are 192.168.1.1, which means the address should be entered something like 192.168.1.60. We just take the address and change the last number to another, for example 60.

DNS can also be specified manually; they will look like this: 8.8.8.8 and 8.8.4.4.

No internet access (yellow triangle with exclamation point)

Or how it is displayed in the status “Without Internet access”.

This message says that the cable is connected and everything is working successfully, including the router, but there is no access to the Internet. Perhaps the router itself is not connected to the network, or has incorrect settings. In some cases, problems may arise from the provider, so you can contact him and clarify.
