Common reasons for not having internet on Windows 7

Internet on Windows may be denied in the following cases:

  • incorrect PC and router settings;
  • non-payment for the next day or month after the end of the previous one;
  • power outages at the locations of the provider's or cellular operator's infrastructure;
  • an accident on a network section (damage to communication lines during excavation and construction work);
  • rebooting of the provider's or operator's equipment during rush hour or due to strong interference;
  • cable damage, router failure for the user;
  • missing device driver, damaged driver files on drive C;
  • viruses or errors Windows 7 that caused insufficient SYS / DLL system files.

A non-working Internet on a user's PC manifests itself in different ways. The following errors are more common:

  • unknown network without Internet access;
  • non-working default gateway;
  • no sound when accessing the Internet;
  • files not downloaded from the Internet;
  • specific (numbered) connection errors related to Internet protocols, addressing, ports, and services.

The latter case requires a special approach to correcting Internet access.

Unidentified network

Most often, the unidentified network in Windows happens due to the work of the provider. Today you have registered IP settings that worked yesterday, but today they are regarded as someone else's.

Unrecognized network at Windows 7

There will be no internet connection until the network is detected

Take a high-speed wired connection as an example.

Changing basic IP settings

  1. If your connection does not go directly, but through a router, then disconnect it and connect the provider's LAN cable to the built-in LAN adapter of the PC.
  2. Go to the connection settings along the path: 'Start' – 'Control Panel' – 'Network and Sharing Center'. Network map with current connection at Windows 7

    An unrecognized network would hide the name of the Internet gateway

  3. Go to 'Change adapter settings', select the broken connection and right-click on it. Select Properties from the context menu. Entering the properties of an unrecognized connection at Windows 7

    Disconnect the connection before configuring it

  4. Select the component 'Internet Protocol TCP / IP', next to it click on 'Properties'. Connection properties

    Select the component 'Internet Protocol TCP / IP', next to click on 'Properties'

  5. If your ISP did not provide you with an IP address, enable auto-assignment of addresses. Specifying IP Addresses

    Turn on auto-assignment of addresses

  6. Close all windows by clicking 'OK', restart Windows.

If unsuccessful, repeat these steps on another PC.

Fix TCP / IP protocol failure

A radical option is through the command line Windows. Do the following:

  1. Run the Command Prompt application as an administrator. Run cmd.exe as administrator

    Administrator rights are required to execute system commands

  2. Run the command 'netsh int ip reset resetlog.txt'. It will clear the reset history of your connection. Executing the command to clear the connection log in Windows 7

    All commands are run by pressing enter on the keyboard

  3. Close the Command Prompt application and restart Windows.

Perhaps the unrecognized connection will be cleared.

DHCP problem

If the network you are connected to is still 'not recognized', reset the DHCP settings:

  1. Run Command Prompt Windows with administrator rights and enter 'ipconfig'. The 'IPConfig' command will display information about the connection setup

    Displaying current settings by 'IPConfig' command

  2. If the address 169.254 .. is entered in the 'Default gateway' column, then reset your router (if you are using a router). Restart your PC.

If the router is not in use, check all the settings from the device manager Windows:

  1. Follow the path: 'Start' – 'Control Panel' – 'Device Manager'. Login to 'Device Manager' at Windows 7

    Turn on icon display (classic view) to find it easily

  2. Open the properties of your adapter, click on 'Advanced', click on 'Network Address'. Failed network adapter properties in Windows 7

    Checking adapter properties will give an opportunity to reset it

  3. Enter an arbitrary cipher in hexadecimal (12 characters). Close all windows by clicking 'OK'.
  4. Enter 'ipconfig / release' and 'ipconfig / renew' commands at the command line. These commands will restart your network adapter.
  5. Close all open windows and restart Windows.

In case of failure, contact the provider's support.

    Go to the 'Power Management' tab

  2. Disable the auto power off function.
  3. Close all windows by clicking 'OK'.
  4. If you are configuring a wireless adapter, go to 'Start' – 'Control Panel' – 'Power Options' and specify the maximum performance. Enabling the wireless network for maximum performance in Windows

    This is necessary so that communication does not go into standby mode.

  5. Close this window by clicking 'OK' and restart Windows.

Configuring the default gateway manually

This method is suitable for both Wi-Fi routers and purely wired routers (for example, if you are setting up a connection in a large company office, hospital or university) and routers operating in a combined mode (for example, as an access point in a store, office or an internet club).

  1. Open the already familiar properties of your network adapter.
  2. Open TCP / IP (version 4) properties.
  3. Enter specific IP addresses. So, if you are using a router with the address 192.168.0.1, register it as the default gateway. Manual entry of IP connection settings in Windows

    Auto-assignment of IP will only help when accessing the Network without settings (cellular operators)

  4. You can also enter the well-known DNS addresses – 8.8.8.8 and 8.8.4.4 (Google addresses). They can speed up the connection.
  5. Close all windows by clicking 'OK' and restart Windows.

Network adapter driver management

Drivers imposed by the company Microsoft with the next update Windows do not always work.

  1. Open the familiar properties of the network adapter using Device Manager Windows.
  2. Go to the 'Driver' tab and uninstall the official driver that came with Windows. Broken network adapter driver properties

    You can remove or disable this device in the system Windows

  3. Download on another PC or gadget and transfer the driver installer for this problematic adapter. Install it by running your installer or using the Update Driver Wizard in Device Manager Windows. When reinstalling devices, it is advisable to take the drivers directly from the manufacturer's website of your device. Command to start driver update in Windows

    Update driver – download and install a newer version

  4. When finished, restart Windows.

If changing the driver only made it worse, return to the same driver properties window and use the rollback of your adapter.

Troubleshoot a gateway error using the FIPS feature

Please do the following.

  1. Enter the familiar network connections folder Windows 7 by going to 'Start' – 'Control Panel' – 'Network and Sharing Center' – 'Change adapter settings'.
  2. Right click on the connection icon. Select 'Status'. You can also open a working connection by returning to the main window of the Network and Sharing Center and clicking on the name of the wireless network. Opening connection information at Windows 7

    This will display information about traffic and time, buttons for entering settings, etc.

  3. Click the 'Wireless Network Properties' button in the window that opens. General connection information window at Windows 7

    Entering Wireless Properties

  4. Click on the Security tab. Wireless security properties at Windows 7

    Entering additional parameters

  5. Click on the 'Advanced Security Options' button. Enabling FIPS

    FIPS will help solve the problem with connecting to the common gateway

  6. Enable the FIPS option, close all windows by clicking 'OK' and restart Windows.

Error 619

This error reports the closing of software ports Windows.

Please do the following.

  1. Restart Windows.
  2. 'Re-plug' your connection and reconnect.
  3. Disable the 'Firewall Windows' service (via the services in the 'Task Manager'). Disable Firewall Windows in Service Manager Windows

    Click the stop button, disable autoplay and click 'OK'

    Disable encryption in the security tab of the connection properties

  5. Update or reinstall your network device drivers.

Error 638

This error means that the remote computer did not respond in a timely manner to your request.

Error 638

No response from remote PC

The reasons:

  • unreliable connection (damaged cable, connectors);
  • the network card does not work (the card itself or the driver is damaged);
  • errors in connection settings;
  • peripherals (wireless adapter or cellular modem, router, switch, LAN-Hub or server patch panel) are disabled;
  • update errors Windows;
  • viruses in the system;
  • incorrect installation of application programs;
  • deleting or replacing system files with their unknown versions (usually the protection of files and folders of the C: \ Windows \ directory works).

What can you do:

  • check if the router is working (hub, switch, patch panels, etc.), whether its indicators are on, signaling the switched on state and the LAN / WAN / Internet / 'wireless' operation; Examples of working routers ZyXEL, TP-LINK, DSL modems

    This is how the display panel of the device in use looks like

  • restart the computer and all devices (which are) in order to unload the ahead-of-load buffer (peripherals hang when this buffer overflows);
  • check if the program addresses and ports on the router (or on another intermediate device) are open, if they are blocked by a firewall Windows;
  • check the DHCP settings (auto-assignment of addresses to each PC from the router or router pool).

Error 651

There are several solutions to this error.

Device response message for error 651

Network device reported error 651

No modem or router

The tips are as follows.

  1. Reconnect the LAN cable.
  2. Check if antiviruses and other utilities that prohibit addresses, ports, protocols and Internet services have been installed. Remove all of these programs temporarily.
  3. Disconnect the second device (cellular tethering, Wi-Fi network adapter), if available.
  4. Restart Windows.
  5. Reinstall or update the network device driver (see instructions above).

With a router

  1. Restart the router through which the Internet from the provider goes.
  2. Reset the settings by pressing the Reset button for a few seconds, re-enter the router from any browser and configure the router in accordance with the instructions received from the provider.

Error 651 is usually associated with a high-speed connection. And it, in turn, is the task of the router itself, all you need to do is configure the distribution of the Internet via cable and Wi-Fi, which is performed after buying the router or after the next reset of its settings.

Each router has a reset button on the back

Holding it down for a few seconds, you will reset all the settings you made

Second network card or adapter

See which networks you are connected to.

One network and one device per Windows 7

This device has internet

Only one adapter should work, from which you get the Internet. All others must be turned off. Go to the 'Network and Sharing Center'. If you have two cables from different providers, disconnect one of them.

Section 'Changing network parameters'

If you have two cables from different providers, disconnect one of them

Self-disconnecting adapter

Your connection often disconnects itself. After right-clicking and selecting 'Connect', you find that the statuses change one by one, for example: 'Network cable not connected' – 'Identification' – 'Disconnected'. When this occurs, a notification about error 651 appears. Reinstall or update the network device driver.

Adapter not involved

Please do the following.

  1. Open the already familiar Device Manager Windows by going to 'Start' – 'Control Panel' – 'Device Manager' and find your adapter in the list.

  • rollback Windows to an earlier date in the recovery marks calendar;
  • repair Windows from the image on the installation media (the troubleshooter Windows can be run);
  • complete reinstallation Windows.

Error 691

The essence of the error is incorrect connection security settings (wrong server, wrong credentials, PPPoE technology does not work).

Request message with error 691

It appears in Windows XP / Vista / 7

The message can be more detailed.

Detailed error message 691

Windows also offers to record these cases in your history

Login and password error

This is the most common reason for error 691. It is necessary to correct the incorrect login and password, server, port and dial-up command (if any) in the connection settings. The instruction is the same for Windows XP / Vista / 7.

  1. If authorization fails Windows, you will be prompted to enter your username and password manually. Windows asks for a name, password, dial-up blitz, etc.

    This happens when the automatic connection fails.

    Click 'OK' to complete the installation

  9. Close all windows by clicking 'OK', restart Windows.

Files are not downloaded from the Internet

It happens that you have just successfully 'surfed' the sites, and the download has become impossible. There are many reasons.

  1. Access to the requested file is closed by law. Use anonymizers, VPN technology, Tor, and other tools to bypass the blocking that most users have found inappropriate. Do not use site blocking bypass to gain access to extremist sites, to maintain an information war against the government and peoples of different countries, to distribute pornographic materials, etc. Yota provider rejected request for torrent tracker rutracker.org

    Blocking access to your favorite site may appear at any time

  2. The website owner has moved, renamed or removed this file at the request of the copyright holder or independently. Removing a movie from the resource at the request of its creators

    In this case, it is worth looking for the same movie on other sites.

  3. Sudden disconnect. Permanent disconnects associated with network congestion. For example, this was manipulated by MegaFon before the mass distribution of 3G networks in Russia, installing in 2006-2007. the session time is 20–46 minutes, which subscribers often complained about when the traffic was rounded up to 100 Kbytes within each session. Some of them, trying to download something 'heavier' through slow GPRS / EDGE and not having a download manager with resume at breaks, ended up in a decent waste of money from the account. Later, with the proliferation of 3G networks and the launch of 4G, this problem was eliminated and forgotten. Now the constant breaks have been replaced by 'smart' shaping – a forced reduction of the speed within high-speed traffic during peak hours and 'cutting' the speed to 64–128 kbps after its main quota is exhausted (fighting torrent lovers). An example of a speed limit when monthly or daily traffic is exhausted

    Beeline for Magadan subscribers cut the speed to 16 kbps

  4. Unscheduled write-offs of money from the account: connecting entertainment services without the knowledge of the subscriber, connecting additional services when changing the tariff, premium payment for traffic from third-party resources (category of additional write-offs of funds that lie outside the 'native' unlimited limit on the main tariff). The subscriber's balance became negative, and access to the Network was suspended. An example of extra charges from MTS for requests / SMS to some short numbers

    The user allegedly sent requests for numbers they did not actually request

  5. Sudden power outage of the periphery: you tried to download, and at this time the router or switch rebooted or went out on its own. Many modern devices, especially those with a battery, can shut down due to discharge and / or overheating, being in heat or in conditions of poor ventilation. It is not for nothing that operators install additional air conditioners in their BS containers: without them, the radio equipment of 2G / 3G networks heats up no worse than a processor or computer hard disk, turning the occupied room into a 40-degree oven in summer. For 4G networks, equipment cabinets are provided that are installed directly on street poles at a height of 3-5 m, so cellular networks today are very reliable and do not allow many hours of interruptions in the work of their 'towers'.
  6. Viruses that have infiltrated the system Windows, damaged, multiplied system processes (for example, explorer.exe, services.exe, visible on the Processes tab of the Task Manager Windows) and created a 'gross' traffic load on the bandwidth of your Internet channel (for example, the Yota 4G modem with the declared 20 Mbps is 99% blocked, as can be seen on the Network tab), they often do not allow anything to be downloaded at all. Numbers and graphs show hundreds of megabytes per minute at a breakneck speed, the connection seems to work, but you can't download a file or even open a website page. Viruses often spoil the settings of browsers and network connections Windows. Everything is possible here: from unauthorized reconnections, disconnects to 'stuck' incoming traffic (connection is limited or not available) and calls to Honduras (in the old days, a subscriber had to pay up to 200,000 rubles for an intercity).
  7. Suddenly the payment for unlimited or high-speed traffic ended (you forgot when you paid for your Internet).

Internet sound does not work

There are many reasons, a solution can be found for almost everyone.

  1. The speakers are not turned on, the cable from the audio output of the PC or laptop is not connected to the input of the speakers.
  2. The sound is muted in the system Windows. In the lower right corner of the screen, next to the clock, there is a speaker icon. Check at what level its slider is.
  3. Check if the sound works in the program you are using, for example, in the settings Skype.
  4. Restart Windows – the sound driver may temporarily crash.
  5. Update the Adobe Flash Player component.
  6. Update your sound card drivers. Go to the already familiar Device Manager window, select the 'Sound and Audio Devices' category, right-click on them and select 'Update Drivers'. Follow the instructions of the wizard Windows. Trying to update sound card drivers to Windows 7

    Start the update process, follow the instructions of the wizard

  7. Check plugins and browser extensions (e.g. Google Chrome) where audio has disappeared. Disable them one at a time, while launching some online radio station and checking the sound after disabling the next plug-in on the play button on the site of this radio station.
  8. Another reason may be viruses that disrupted the processes of the PC or laptop chipset driver, damaged the files of the sound driver, arbitrarily setting their own incorrect sound settings, because of which the latter became poorly distinguishable or even turned off. In this case, troubleshooting the installation media and reinstalling drivers, including network and audio drivers, will help.

PPPoE Diagnostics

PPPoE is a point-to-point protocol that connects computers (servers) over an Ethernet cable connection at speeds up to 100 Mbps, which is why it is called high-speed. Diagnosing PPPoE connections is needed to troubleshoot or resolve network equipment configuration issues. Take the ZyXEL Keenetic 2 router as an example.

PPPoE itself is one of the tunneling protocols, along with PP2P and L2TP. And PPPoE diagnostics are detailed event logging needed to solve connection problems.

  1. To start diagnostics, give the command 'System' – 'Diagnostics' – 'Start debugging' in the web interface of the ZyXEL router. Launching ZyXEL Keenetic 2 debugging

    Click the start debug button

  2. A special marker indicates that debugging is running. Debugging started on ZyXEL Keenetic 2

    Running debugging is indicated by a special marker

  3. To turn off debugging, return to the old diagnostic submenu and click on 'End Debugging'. Finishing debugging in ZyXEL Keenetic 2

    Click the end debug button

  4. After debugging is completed, the self-test.txt log file will be saved on the PC, which can help ZyXEL specialists deal with the problem of connections going through the router. Saving a ZyXEL Diagnostic File to a PC

    It can be transferred to technical support

PPPoE connection errors

To successfully diagnose PPPoE connections, it is important to know about errors that can become a stumbling block for users Windows 7. Some of the errors were discussed above, but in fact there are many more.

Error 629

The essence of the error: the connection was interrupted by the remote computer. This happens when there is already a PPPoE session, but you initiate another one. Two simultaneous PPPoE connections will not work. Complete the previous connection and only then create a new one.

Error 676/680

The instruction is the same for Windows XP / Vista / 7. Do the following:

  1. Follow the path 'Start' – 'Control Panel' – 'System' – 'Hardware' – 'Device Manager'.
  2. Select your adapter from the list of devices. Entering the list of devices and choosing your network card

    Click on the + to open the device category (for example, network adapters)

  3. Right-click on it and select 'Enable / Disable'. By turning your network adapter off and on, you kind of restart it.
  4. If the driver is not installed correctly, remove the device using the 'Uninstall' command and then update its driver with the 'Update drivers' command.
  5. It happens that the network card is disabled in B IOS / EFI. According to your PC motherboard or laptop documentation, enable the network card in settings B IOS / UEFI.

Error 678

This error occurred in previous versions Windows. For version 7 it is equivalent to error 651 (see instructions above).

Error 734

The essence of the error: the PPP connection control protocol was stopped. Do the following:

  1. Open the already familiar properties window of your connection, go to the 'Security' tab and select the 'Secure password' authorization type.
  2. Close all windows by clicking on 'OK', restart Windows and reconnect.

The problem will most likely be resolved.

Error 735

The essence of the error: the requested address was rejected by the server. Incorrect high-speed PPPoE connection settings. The instruction is also suitable for Windows Vista / 7. Do the following:

  1. Open the network connections folder in the Network and Sharing Center. Further, the instruction coincides with the settings Windows XP. Start setting up a high-speed PPPoE connection

    Entering PPPoE connection properties

  2. Go to the properties of the network connection and go to the 'Network' tab.
  3. Click on 'Internet Protocol (TCP / IP)' with the right mouse button and select 'Properties'.
  4. Assign those IP addresses for the range of which your network to which you are connecting is configured.
  5. Close all windows by clicking 'OK', restart Windows and reconnect.

Error 769

The essence of the error: it is impossible to assign the specified purpose to the network.

The setup largely repeats the steps for eliminating error 676. Check the availability of your network card by all of the above methods, the operability of its driver.

How to avoid internet problems in Windows 7

General tips are as follows:

  • do not use too old network devices. It is useful to switch to a new technology of the used network as soon as possible, for example, when a 4G connection appears in your area from any of the operators expanding the service area, switch to 4G. If you don't have a new device, get one as soon as possible.
  • always use the latest network device driver whenever possible;
  • try to update regularly Windows, install at least critical updates;
  • use antivirus or all the features of 'Defender Windows', also keep the firewall Windows ready;
  • if possible, use the second connection to the provider or operator as a backup;
  • promptly check with the provider the reasons for the problems with Internet access;
  • place your networking equipment in a safe and well-ventilated place so that it does not turn off due to overheating;
  • keep installation disks and / or flash drives handy so that in case of persistent problems, you can roll back or reset Windows to the original settings. After the reset, configure your connections again, check (if necessary, install) the drivers of your network devices;
  • cables (if they are used) must be laid in safe places of your house or apartment (for example, in baseboards, in boxes, under the ceiling, wall panels, etc.) and have sockets, necessary adapters for easy disconnection when rearranging, transferring a PC and / or periphery so that they cannot be damaged by careless movements;
  • use a proprietary router, modem, terminal and / or wireless modules from well-known companies that have long-proven themselves (Nokia, Motorola, Asus, Apple, Microsoft, ZyXEL, etc.) as reliable suppliers. Do not use devices from manufacturers that appeared almost yesterday, as well as the Chinese 'know-name' (it will last you six months or a year), which will fail shortly after purchase. Even if the manufacturer is Chinese, chasing excessive cheapness, you will get an insufficiently functional and low-quality network device.

Whatever the errors with the Internet in Windows, you can successfully solve them if you use proven methods. And to avoid problems with the Internet in the future will help the general tips presented in the article.
