Network without Internet access and ways to solve the problem. Causes and solving the problem "Unidentified network without Internet access video: Checking a port on a network card and WAN port on a router

Today, for many, it is already an urgent need. Modern equipment and operating systems are becoming increasingly intelligent, and the user has the need to do anything less often to configure. However, occasionally such a need arises. Today we will tell you how to solve the problem if the computer reports that you are connected to the network without access to the Internet, and you see a yellow triangle with an exclamation mark near the connection icon.

Microsoft operating systems, starting with Windows 7, constantly monitor network connections, and since soon global network Not available, immediately report it. The reasons for which there may be no connection to the Internet on the computer, not so little. Such may be the problem of the provider, invalid configuration Equipment from the user or failures network Protocols. Today, the new IPv6 protocol is becoming increasingly distributed, but the percentage of it is still very small, so more so in home networks, therefore the focus will be paid to the old version - IPv4.

Connection via a router over a network cable without internet access

Problems from the provider

Yesterday everything worked, and today this warning appeared. If you have so happened without visible reasonsIn most cases, the problem of the provider. Therefore, before doing anything yourself, call technical support. Most often damage to data lines, some technical works are carried out or you just forgot to replenish the account.

Perhaps you will hear in response that the provider does everything work well, then you need to check your network and, if necessary, configure it. The support service will surely offer their master's services, but, first, its services are not free, and secondly, during the time, while the master gets it, you can have time to solve the problem yourself.

The problem with physical connection

Not so rare cases when the wines of everything is partially interrupted network cable or a dischargeable connection in the connector. And if you have pets or children, the probability of such developments increases. Even wi-Fi users don't forget that wireless router Also stretched the cable. Check the integrity of the entire wiring - there is no strong beggars anywhere, whether all the plugs are tightly inserted into the sockets and whether they are inserted wherever need. Provided that the problem is not detected here, go to the next stage.

Connecting to local network Windows 7 without access to the Internet

It happens that the installed router tritely freezes. In this case, helps. To do this, it is enough to turn off the power from it and connect it again after a few seconds. It does not prevent at the same time restart and computer. If it happens that such hangs of the router occur with annoying regularity, think about buying a new device. You also need to try to connect an Internet cable directly to a PC or laptop. In the absence of the result, I will understand the computer to begin with.

Check the computer settings

It is possible that the problem arose "on the level place", then there should be no questions with the settings on the computer, much more often the problem occurs during the initial configuration or making any changes to the already operating network. First of all, it is necessary to check the correctness of the IP address of the computer, for which you press on the keyboard at the same time Win + R. The "Run" window opens. In its row, enter NCPA.CPL and click OK. The network connections window appears. It may happen that there are several of them, but the necessary will not be crossed out with a red cross and its name is similar to "Connecting on a LAN" or " Wireless connection"(If using Wi-Fi). Press the desired connection Right-click and go to properties where the list will be lines with IPv4 and IPv6 records. Check for a tick opposite IPv6, and on the IPv4, click twice. Mark the items of automatic settings and save the changes. If access to the Internet does not appear, go further.

Setting up a local network connection in Windows 7

Find out the address of the router

Perhaps in the previous window did not have to do anything, the settings for receiving IPv4 and IPv6 addresses are automatic and everything was originally as needed. Then you should only configure the router, for which it is necessary to know its address. Make the right click on the connection and select "Status", and then click "Details". In the window that appears there will be several lines, we are interested in the "IPv4 address". If you see an entry of the form of 192.168.x.x, remember or record what is indicated opposite the "IPv4 DHCP server" - it will be its address. It may be so that the computer is not able to get the settings automatically, then the record will be viewed 169.254.x. You can find out the IP of the router from the documentation for it, or it is specified on the device case, and most often it is 192.168.0.1 or 192.168.1.1. Open your browser and enter the installed IP in the address bar, and, if it is faithful, a request to enter a login and password will appear.

Properties "Internet Protocol Version 4 (TCP / IPv4)"

Configure the internal network on the router

After entering the credentials, you will fall into the router control panel, and further actions depend on the device model and its firmware. You need to find the DHCP server management that is responsible for automatically obtaining IP addresses and other parameters required to function normally. Look for blocks in the title of which the DHCP Settings, DHCP server or similar are specified. The block will contain a switch with Enable values \u200b\u200b(allow) or Disable. Most often, these settings are located in the LAN section. Turn on the DHCP server, save the changes and restart the router. The field of this, the computer will be connected to the Internet.

Check the connection settings for the provider

Do not have hasty conclusions if the previous actions did not help configure the connection. Since the network is still not working normally, check the connection to the provider, for which in the router control panel, go to the appropriate section. Almost all manufacturers, these options are called WAN or Internet. Settings options in this section are quite a lot. What are you intended for you, you can learn from the contract or in the technical support of your service provider.

Reinstalling the network card drivers and checking the firewall

Doing it makes sense when you are sure that all previous settings are correct, the connection with the provider is installed, but the network cannot be configured normally. The best option will download the latest version of the driver from the manufacturer's website, which seems to have to go to a friend or neighbor. In the absence of such an opportunity, it is quite suitable that driver that is attached to installation disk. After reinstalling, be sure to restart your computer. Here it is also necessary to note the crashes in the drivers arising from the established softwarewhich makes changes to the operation of the network protocols on the computer. Most common representatives are antiviruses and network screens. Make sure that such programs are not installed, and if available, then disconnect or delete them by checking, as they can block the connection.

Replacing the MAC address of the network card

Problems with MAC addresses sometimes occur in cases where the network is very large, but it is still worth excluding it. On your computer, go to the Device Manager, for which press Win + R keys, enter Devmgmt.msc and click on OK. The device manager will start, where you need to find the "Network Adapters" section, deploy it and select a network card with which PC is connected. After a double click on it, in a new window, on the "Advanced" tab, select the Network Address parameter and enter any twelve digits to the empty field on the right. After that reboot and look at the result.

Clearing DNS cache and reset TCP / IP settings

Subsequent actions will reset all network settings For IPv6 and V4, so you need to perform them. If you are ready for this, you have information about all the settings (somewhere recorded, for example), find the "Start" menu command line And run it with administrator rights. Enter the above commands in the window that appears, confirming the entry by pressing ENTER. After working out each command, restart the computer and check the result.

ipconfig / Flushdns.
netsh Winsock Reset.
netsh int ip reset c: \\ resetlog.txt - This command will completely drop all connections and have to be configured again!

Cleaning cache DNS. C command line

You have a direct connection to the provider

Option when your computer is connected directly to the provider, bypassing the router, currently meets more and less often, since the number network devices steadily growing. But what if you have this connection? Eliminate possible problems With drivers as it was indicated above, and check the correctness of the connection settings. Regarding the settings, the best option will apply to technical support, since there are a large variation here.

Nothing helped at all

Maybe you are lucky and your provider provides access using the new IPv6 protocol, which requires knowledge of some subtleties. It should be noted that the expansion of the use of IPv6 is inevitable because the address space previous version Protocol, IPv4 approached the end, and the global network grows with each day. Once, the efforts were spent, and did not earn your network, then the advice is only one - call the masters. It is quite realistic that the problem that has arisen has a non-standard or to solve it requires a replacement / repair of equipment.

Internet access is, but the error remains

This situation may well be. Causes can be different - most often when connected through a proxy server. However, the decision is one. Press WIN + R, enter the gpedit.msc - so you will fall the editor of the local group Policy. In the Left menu, go through the items: Local Computer Policy - Computer Configuration - Administrative Templates - System - Communication Management via the Internet - communication parameters via the Internet. Now, on the right side of the window, find and turn on "Disable the active sensing for the Network Connection status indicator". In Windows 10, this parameter is called "Disable Active Network Connection Operations." Call the fact that now even with a really missing connection, the message will not appear.

Conclusion

This article contains the most common problems associated with the error "Network without Internet access" and proposed ways to solve it. We hope that the material was interesting to you and helped yourself to overcome the difficulties.

If IPv6 protocol some providers do not support, and in the bundle with the router the protocol is not used, then IPv4 is directly responsible for the presence of the Internet. Therefore, in the article, we will consider ways to troubleshoot when the "IPv4 without Internet access" appears.

Why an IPv4 error occurs without internet access

When using the Internet, the chain consists of three segments - provider, network and user equipment. Failures or problems in one of the listed segments, and lead to the absence of the Internet. And the search and troubleshooting in the router or computer - do not fix the problem if the problem has arisen from the provider. Therefore, to save time and effort, it is important to understand and identify a problem segment.

The best way to determine is the exception of superfluous:

Call the operator and make sure your address is correct.
If you are used router, check the location and wireless networkBy connecting other devices. In the absence of restrictions on the part of the provider and working capacity with other devices, the problem should be signed in the main computer.
Connect the Internet cable with the main computer network card. In the absence of restrictions on the provider and Internet serviceability, the problem should be sought in the router.

Another way is to diagnose OS.

If the error occurred due to the fault of the provider

Contact the Internet provider and find out why there is no connection. In the event of an accident or execution of scheduled maintenance / equipment replacement, the provider is obliged to communicate the final end of the completion of the repair work. If the network cable is damaged, request a wizard for replacement.

In apartment buildings, the provider equipment is located mainly on the roof. When de-energizing or in power failures, the equipment is turned off. After power supply, it is usually required for 5-10 minutes to turn on. Sometimes it is required to restart the computer / network equipment to resume work. Also, the internet failures can be observed during thunderstorms.

If the error occurred due to the router

Before switching to the search and eliminating likely reasons, make sure that the network equipment is connected correctly. When connecting the wires, it is important not to confuse LAN and WAN ports. Sometimes the network cable is delicately installed in the WAN connector. Therefore, it is important to check the density of the connection.

Solution 1: Check Connection Settings

Open the router control panel and go to the network settings. Make sure that the WAN connection type is set correctly, and the parameters are specified in accordance with the requirements of the provider.

Also open the DHCP settings. The server must be included. The initial IP address - 192.168.1.100, the final - 192.168.1.199.

Solution 2: Reset Settings / Change Firmware

Sometimes the router refuses to save the entered settings. In this case, the reset and re-configuration helps. Sometimes it is required to replace the firmware, in rare cases, replacing the router itself.

If the error occurred in the computer

Solution 1: Check Connection Settings / Register manually gateway address

Open network connections where you select your internet connection properties.
Select the IPv4 protocol, and then open Properties.
Make sure the settings are exhibited correctly. If you are connected via the router, use the automatic receipt of parameters.

Sometimes DHCP server Does not pass the address of the gateway. In this case, you need to register the gateway manually. The required data will tell you the provider when contacting.

Also try specifying the automatic receipt of the IP address. In values DNS Server Specify:

Preferred - 8.8.8.8.

Alternative - 8.8.4.4.

Solution 2: Disable or change the frequency screen settings

If the message "IPv4 without Internet access" appeared after installing an antivirus or firewall, or interference with the settings, then for a while, turn off the programs.

Sometimes you need to disable the built-in Windows Firewall. To do this, open the control panel, then "System and Security". In a new window "Windows Firewall", and after "Enabling and Disable Windows Firewall".

Solution 3: Disable energy-saving functions

The active modes of energy saving contribute to the temporary or constant internet disconnection. Therefore, it is necessary to double-check and disable the corresponding functions.

Power Mode

Open the "Power" mode, as shown in the images below.

Select Balanced or High Performance Mode.

If changes were made in the plan, return the settings to the original state.

Advanced network card options

In the control panel, select "System and Security".

In the "System" section, select Device Manager.

Find the Network Adapters in the list.

Open the network card properties.

On the Advanced tab, find green and energy-saving functions. In the value of each item, select "Disable".

Output

When IPv4 errors appear without access to the Internet, make sure that the problems are not on the side of the provider. Disconnect the router to exclude problems in network hardware. If the malfunction is related to the computer - set the IP address and DNS server parameters manually, or use automatic or semi-automatic parameters, for example, only with the address of the servers address. Even disconnect the power saving functions to prevent Internet disabling.

The Internet is an integral part of our life. Lack of network is a serious problem for the user. There is no time to get through to the provider, but fortunately, it is possible to eliminate malfunctions. Below you read about the common causes of Internet problems and about how to eliminate them.

Possible causes of lack of Internet on windows 7

There are several reasons for the absence of the Internet. Some of them relate to computer drivers and its equipment, others affect system errors And the absence right settings network.

The most common causes of the absence of the Internet are:

mechanical damage to cable or ports;
lack of a network card or its drivers;
incorrect configuration of the connection on a computer or router;
the presence of viral software.

The Internet may also be absent due to debt on facial account Or because of the accident on the line. Before trying to eliminate malfunctions, check if they are not caused by these factors.

How to check the status of the network

Among the problems with the Internet, you can select those that are found most often and periodically arise from most users. Allow them is very simple. The first thing to do is check the status of the network.

You can do this in two ways:

In both cases, its state will be described under the icon of your network.

Unidentified Network without Internet access

If the computer "sees" the network and connects to it, but does not receive access to the Internet, the status of the network will be called this: " Unidentified Network. Without access to the Internet. " What to do in this case?

The computer "sees" the network and connects to it, but does not receive Internet access

Reloading router

If you have a router, the first thing to do is restart it. He may simply do not have time to update the data, and because of this, access to the network will disappear. The reboot is performed in the following order:

First, the router is disconnected from the network. It is important to pull out the cord from the outlet, and not to restart using the button on the equipment - you need to stop the flow of electricity for a while.
Then for 10-15 seconds, the router must be left disabled.
After that, the router is connected back to the network and wait until the indicators light on it.

After the indication on the router appeared, you can check whether access to the Internet has appeared. Usually after rebooting the Internet appears within 7-10 seconds.

Checking network settings

Network settings are the data that allows the computer to connect to the distributed network provider. These settings produce a company that provides access to the Internet (usually registered in the contract for the provision of services). Sometimes the settings on the computer are knocked up, and because of this, the device cannot connect to the Internet.

In order to check the network settings, you need to open the Protocol properties. You can do it like this:

Go to the "Control Panel" through the "Start" menu.
The "Control Panel" is located in the start menu "Start"
Select "Network and Internet".
In order to find need section, you should select the "Category" viewing parameter in the right upper corner Screen
Open the Network Management Center section common access».
In the "Network Management Center" you can check the connection status, create a new network, carry out almost any actions with your internet connection.
Find the "Changing Adapter Settings" section.
Find the section "Changing the Adapter Settings"
In the list of networks, select the desired one, click on it with right mouse button and find the item "Properties". Open "Properties" can only administrator.
The network you need will be called "Local Connection" or "Ethernet"
In the list, find the "Internet version 4" item, highlight it with a single click of the left mouse button. After that, the "Properties" button is activated under the list, you need to click on it.
The selection of the item is made by a single click of the left mouse button. Take a tick next to the item not needed

When the window is open, you need to still understand which settings must be entered. There are three options:

We understand what is an IPoe and PPPoe protocols, but we will not go into terminology. It suffices to understand which protocol is used on your link. To do this, just look at the network settings issued by the Provider (specified in the contract).

Settings may be the following:

password and login are used on PPPoE protocol,
IP address, subnet mask, gateway and DNS are used on the IPOE.

If you are using PPPoE and you are connected directly, that is, you do not use the router, after checking the settings through the Properties of the Protocol you need to re-create the network.

Return to the "Network and Common Access Control Center".
This configures only PPPoE connection. For settings wired connection IPOE used Protocol properties
Open the "Creating and Configuring New Connection" item.
Point switching is performed by a single mouse button.
Select "Creating and Setting new network"And click" Next ".
The selected item will be highlighted with a bright blue background.
Click on the "high-speed" version.
Waiting for search available connections may take a few minutes
When an error occurs, select "Create a connection anyway".
This error It appears quite often, but the connection still can be created
Next, you will need to enter network settings, as well as the network name - is the name of the connection. You can use the name of the company-provider or other.
The connection name is its name, and the username and password are network settings. It is worth noting that the password has nothing to do with the wi-fi key.

After that, the network will be updated, and you will need to check the availability of network access.

Reset TCP / IP Settings

Sometimes the cause of problems can be internal system errors. TCP / IP - a set of network protocols responsible for data transmission. You can reset it as follows:

Check drivers

The reason for the lack of access can be outdated drivers (usually such a problem is related to the recent update of the operating system). Check their condition.

In addition, by right-clicking on the driver name, you can select "Delete" item, and then restart the computer. Then, when turned on, the system will automatically install a missing driver.

After removing the drivers and reboot the computer, the system will automatically install suitable drivers

If next to the driver icon is exclamation pointYou will need to fully reinstall drivers and check the performance installed in the computer network card.

The default gateway is not available

Detect the next problem will help the network diagnosis. Right-click on the icon of your connection, select "Troubleshooting".

Pressing the right-click icon, you can open the "Network Management Center"

If after system diagnostics there is a message about the unavailability of the gateway, the following actions can help.

Ban on disconnecting a network adapter for energy saving

Sometimes the system disables network adapter - A device that allows you to connect to the Internet - to save energy. Try to damage this option.

Find "Device Manager" through the search string in the Start menu.
The opening of the "Device Manager" through the search is not the only way, but the most convenient
Expand the "Network Adapters" tab, select the desired, click on it with the right mouse button.
In the context menu, click on the item "Properties"
Select the item "Properties" and open the Power Management tab.
Changing these settings will help solve and break off the Internet after the computer transition to sleep mode
Remove the mark next to the "Allow shutdown of this device to save energy" and save the data.
After changing the settings, do not forget to save them by clicking on the "OK" button

Update or reinstall drivers

Also through "Device Manager" You can update the drivers: Expand the "Network Adapters" tab, right-click on network Driver And select "Update" or "Delete", after that restart the computer.

If the action does not help, you can download drivers from the sites of their manufacturers and install yourself. Typically, manufacturers offer download .exe driver drivers, so you will only need to start the downloaded file and accept the agreement.

Video: How to reinstall drivers yourself

When connecting to the Internet, an error 651 occurs through the router

This error occurs when you try to connect via PPPoE protocol. Rarely, but it happens that users create a new high-speed connection while the provider uses the IPOE protocol. Therefore, you first make sure that you are using the PPPoE protocol.

After that, you will need to re-create the connection. The process is described in detail in the "Check Network Settings" section (all you need to do, through the "Network Management Center" Create a new connection). If it does not help, read further.

Disable antivirus

Sometimes antivirus programs Block access to the Internet. Often the solution to the problem can be disconnected antivirus. Click on its icon in the Right-click Control Panel and select "Disable". Sometimes antiviruses block access to the network even in the "sleeping" state, so you can try not only to disable, but also completely delete this software. If this action helped, report the situation in technical support Antivirus.

Problems on the router

The cause of problems can be several problems associated with the router:

incorrectly connected cable;
invalidly entered settings.

First try to do the following:

Disconnect the router from the network.
Without connecting the router, pull out the network cable from it and connect back to the WAN / Internet port, making sure that when connecting the plastic clips on the plug closed.
If the cable goes to the computer from the router, disconnect it from the LAN connector on the router itself and from the network card connector on the computer, then connect back.
Connect the router to the network.

If access does not appear, check the network settings entered on the router. In order to go to the router, it will be necessary in any browser (in the address bar) to introduce "192.168.1.1" or "192.168.0.1". Sometimes the address by which you can go to the router is different, so if through specified addresses Log in is not made, check the data in the instructions.

Files from the Internet are not downloaded

It can also happen that access to the Internet is active, and the files are not loaded. This problem is usually associated not actually with the Internet, but with a computer, software.

What you can try to do:

try to download the file from another source - perhaps you can not download anything simply because the resource does not support downloading;
try downloading through other browsers;
check the computer for malicious software using any official antivirus.

Multimedia does not work on the Internet

It happens that the Internet is working, and video or audio materials are not played. What to do in this case? First check whether the files loaded to the computer are played. Perhaps the cause of problems lies directly in sound settings Computer. If the files are reproduced from the computer, but from the Internet - no, read further.

The first thing to be done is to understand why such a problem arises. It can be in the browser error, the absence of plugins. To establish a computer work, do the following:

Diagnostics PPPOE

Additionally, in order to find out the causes of errors when using PPPoE, you can use the "troubleshooting center". Then the system will independently check the presence of errors and offer possible solutions.

PPPoE (Point-to-Point Protocol Over Ethernet) is a communication protocol through ethernet networkwhich works on the principle of "point to point" and gives the user a number of features: encryption, authentication and data compression. It is necessary for the user authorization system, which allows you to facilitate tracking the time of providing and paying network services.

Click right key Mice on the network connection icon and click the "Diagnostics" button. After that, the analysis will be made, Windows will try to cope with difficulties on their own, after which it will offer you to perform several actions.

Error 619.

Restart the computer and disconnect all security systems: antiviruses and Windows Firewall. The latter is turned off in the following way:

Error 633.

There is only one solution option:

Restart the computer.
Try connecting again to the Internet.
Create a new connection.

Error 638.

The main causes of the occurrence:

damage network cable;
disruption of drivers or network fees;
invalid connection setup;
malfunctions on network equipment (router);
the presence of viruses on the computer.

First of all, make two things: check the integrity of the cable and the presence of an indication on the router. Never neglect these actions when issues with the Internet so as not to lose time on trying to solve the problem caused by mechanical damage.

It is clear that if the cable is damaged, you need to call the provider. But if there is no indication on the router (which indicates that the device is de-energized), before it is replaced, try to reconnect the router into another outlet.

After checking the performance of the router and the cable destination, check the computer for the presence of viruses by any antivirus program.

If the above does not help, restore the connection to the network - check the correctness of the entered settings both on the router through the settings and on the computer itself through the Protocol properties. Both actions are described in detail in previous paragraphs.

Error 691.

The only reason for the error is 691 - incorrectly entered password and login (network settings). Therefore, the first thing you need to do is re-create the connection. The process has already been described earlier - you need to go to the "Network Management Center", select the "Create a New Connection" item and then enter the correct network settings. After that restart the computer and check the Internet connection.

If the action does not help, inform the failover of the provider. Perhaps an accident occurred on the line, which caused a mistake.

Error 720.

The easiest way to solve this problem is to reinstall the operating system. To do this, just download from the site. Windows file. operating system to disk (or purchase a disc in the store) and run on the computer.

You can also try to update the TCP / IP protocol. The action is described above, but you can also conduct a deeper operation, fully reinstalling the stack. Reinstall the stack yourself dangerous - work will have to work with system filesAnd their damage will affect the computer. Therefore, try simply updating the stack, and if the action does not help, contact a provider or professional master.

Network cable is not connected

If a message appears when checking the connection status, the network cable is not connected, the first thing is to really verify the correctness of its connection and the absence of damage. If possible, try using another network cable.

Make sure the cable is connected correctly. On the router, the network cable must be connected to the WAN or Internet port, and the cable leading from the router to the computer must be connected to the LAN connector. On the computer usually there is only one port, so it will be difficult to make a mistake.

The WAN or Internet port is used to connect to a power cable router, and the LAN ports are used for cables to computers.

Next, check the state of the router (if any). Its indicators should burn as usual. If there is no indication, reconnect the router to another outlet, try resetting the settings on the router (button "Reset" or "RESET") and re-enter them again. Unscrew the settings should only if you are confident that you can independently configure the router.

Also check the status of the network adapter drivers and try to update them.

Additional safety settings check

Many of these problems may also have security installations. This applies to the case when the PPPOE protocol is used. Therefore, if the proposed operations do not help to solve your case, try checking the security security settings.

Open the "Network Connections" section.
Right-click on your connection.
Open the Security section and install the use of the "unsafe password" in the list that opens.

These are the main ways to diagnose the connection on Windows 7 and troubleshooting. Do not forget that the cause of the absence of the Internet can be a banal arrears or an accident on the line. If the methods described above did not help you, contact the provider in order for technical workers to diagnose and solve the problem for our part.

If you encountered designation Network "Without Internet access" means that your network does not receive packages from outside. The question appears, and what to do and how to eliminate this problem? The universal solution does not exist, you will have to try each of the presented methods before finding out the cause and elimination of an unidentified network.

Possible problems of the provider

The first step in such situations is to call a service provider to find out if there is access to the Internet. On the side of the provider, technical works may be conducted or an unexpected breakdown. In order not to climb in vain, find out the involvement of the supplier.

Call the company's call center, look at the official website or page in social networks. As a rule, they write about actual problems. If the information is missing, look at the comments of other users. Perhaps you are not alone collided with the fact that the computer does not connect to the network. I do not solve problems with the provider, so it remains only to expect.

Cable or connector problems

Next, inspect the LAN cable. Make sure that the plugs are good, do not have physical damage. Inspect the wire isolation and check if there are no beggars. You can try to replace the lan cable connecting the router and computer. If direct connection is used, then exit the partition and to the site by checking the wire along the entire length. If damage is detected, naturally call online managers immediately. They must send the wizard to replace the network cable.

Routher malfunctions

The second most common source of message appearance "without network access" is a router. The list of frequent problems belongs:

selection of incorrect connection type;
setting the wrong IP address or login password (when using ADSL, L2PT or similar connections);
there are any restrictions in the settings;
hardware problem (a capacitor sank or burned the board).

In the latter case, you will need only help professionals or buying a new modem. All software flaws can be eliminated independently subject to the fulfillment of correct action.

When there is no Internet access on the computer, restart the router and PC. During the operation of devices, minor failures may occur, which are not critical. Reboot allows you to eliminate these problems. On the computer, it is enough to click a button that is responsible for this function or select the corresponding menu item in the Start section.

With the modem is all easier: press the POWER button to turn off, and then turn on the machine. If there is no such keys, just pull the power supply outlet.

Settings in the web interface

The installation of incorrect parameters in the modem leads to the creation of a network without access to the Internet. The solution is quite simple: go to the web interface and set the correct parameters. Next, we will tell you in detail about these steps.

How to enter the web interface?

Connect to the modem through the lan cable directly. For entry B. system menu You need to find out the data for authorization (login, password and address to which the transition will be performed). Find this data on the label glued to the device case. Fields are called IP Address, UserName and Password. On some models, they are translated into Russian.

The entrance is performed a couple of steps:

Discover the browser on the PC ( Google Chrome., Firefox, Opera or Standard). Write an IP address to the entrance and Clause Enter in the address bar.
On the Authorization page, fill in the fields (the first is the username, and the second password). Click "Login".

You must get to start page Router settings.

Internet connection settings check

Most routers allow you to use multiple types of connectivity. For each of them require their own parameters:

Problems on a PC or laptop

Try connecting the router to other devices, such as a laptop. Correct work and the lack of error "No Internet access" speaks about problems in a personal computer / laptop that is used to access the Internet.

Diagnosis of problems

Operational windows systems have standard means troubleshooting. They are not always able to return access, but often cope with contacts to the local network. To start the procedure, follow the instructions:

If the faults are not detected, launch additionally points (" Home Group"And" network adapter "). The system will analyze other parameters and may find faults there.

Setting up IPv4.

Despite the global transition to IP version 6, the classic IPv4 is used together, so the incorrect address of addresses can lead to access errors. You can configure the protocol via the operating system interface:

Also addresses can be requested from the provider. When using a static connection, you often need to set parameters in the OS itself.

Reinstalling the network card driver

For the correct work of "iron" in the system used special driver (specialized software). After windows installations Through its base, trying to find drivers to independently put them, but not always successfully. The versions of the disk complete are usually outdated, so we recommend updating the driver via the Internet.

Change MAC Address Network Card

Part of Internet providers uses connection with reference to Mac address. This is a unique identifier that is assigned to any network equipment. At the hardware level, a regular user will not be able to change the mac address, since this requires programmers. However, you can change it at the program level, which is enough to connect to the network.

Change is performed according to the following instructions:

Please note that the MAC address consists of 12 digits in a 16-riche system. To check the correctness of the change in the console, enter the IPConfig / All command.

There is a second method of change through the registry. You need to go through the path of the network card, while changing the value in the NetWorkadress field for the corresponding component.

Check Firevol

The problem is why the Internet is not yet available, maybe in firewall. This is a built-in defender in Windows, which blocks unwanted connections. If there is an antivirus in the system, it can be safely disabled:

Cleaning the DNS cache and reset TCP / IP protocol settings

Go to the "Condition" point of the adapter. Click the Wireless Network Properties button.
Next, go to " Extra options" Put the box next to "Enable Compatibility Mode ...".

If this feature is enabled, try to deactivate it.

If the cable goes to a PC directly (without a router)

With direct Internet connection, all methods are relevant to the computer with the exception of the router setting section due to the lack of the latter. We also recommend re-create a re-connection connection through the "Creating a new connection" item.

There is access to the Internet, but the error does not disappear

The reason for this situation is more often connecting through a proxy server. You need to get to the editor of local group policies. Click Through Starting "Run", and then enter the command specified in the image.

After that, activate the "Disable Active Sensing for the Network Connection" indicator. " In Windows 10, this parameter is called differently ("Disable active network connections performance checks"). At the same time, remember that with actual problems with access, information messages will not appear.

These are all current methods, how to get rid of an unidentified network. If you are a novice, you do not have the experience of configuring a router or operating systemsWe recommend contacting a specialist. Unprofessional intervention can only incur the situation.
