If at starting a VPN connection an error has occurred, then you need to remember its three-digit code. Errors with a 6XX code (errors associated with incorrect entering a password, name or choosing the type of communication protocol and indicate that the network is working, but it is necessary to check the entered data), 7XX (errors related to incorrect and indicate that the network is working , but you need to check the settings) or 8XX (errors related to problems with network configuration or lack of network connection.
Installed anti-virus software and especially firewalls can block the establishment of a VPN connection, causing, for example, errors 789 and 792. In this case, you must enable UDP ports 500 and 4500 in the security settings for communication with the VPN concentrator.
Also, problems with establishing a VPN connection does not occur on computers directly connected to the Internet with obtaining an IP address forwarded on the Internet (and not an address from the private address space: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/24). Otherwise, your local network administrator (or ISP if the private IP address is obtained from it) must configure address translation (NAT / PAT).
Please note that connecting your computer to the Internet means that you can exchange data at the network (IP) level with any other computer on the Internet. Protocols used for VPN connection setup(IPsec protocols) are peers on the Internet with any other protocols that run over a network layer protocol (IP) - for example, HTTP for browsing the web or SMTP for sending e-mail. If your ISP allows web browsing, but it blocks the establishment of a VPN connection, this is an artificial limitation of your access to the Internet.

In the black window that appears in the English layout, type ping XX.XX.XX.XX (XX.XX.XX.XX should be replaced with the address of your gateway, the gateway address can also be viewed in the properties of the TCP / IP network connection) press "Enter" on the keyboard ... If in the black window, five, times or more, the words "The request waiting interval has been exceeded" appear, then call the technical support of your Internet provider.
Various system messages that Windows OS generously poke at its users is an unpleasant phenomenon: in most cases, such a dialogue becomes a harbinger of the next worries about setting up the computer and updating the software.
However, failures periodically occur in any electronic system, and the user's ability to independently eliminate the problems that arise will help him significantly save time and money.
In this article, we will look at what error 638 means when connecting to the Internet, and what to do when "the remote server does not respond in time ...".
Subscribers of all Internet providers periodically face this problem: MTS, Rostelecom, Intertelecom, etc.
The error code 638 that appears when connecting to the Internet indicates that the Internet connection is not active at the moment.
The main reasons for this problem are:
At the same time, even such "trifles" as:
If this error occurs, first of all, you should restart your computer, router, switch and other network equipment used to connect to the Internet.
When using a cable connection, you should also check the integrity of the line and the correctness of connecting the network equipment.
If during a visual inspection the cause of the connection error could not be identified, it is recommended:
Scan your computer with a good antivirus;
Make sure that the drivers of the modem and the network card of the PC are installed correctly and, if necessary, update this software (the presence of drivers can be checked through the "Device Manager");
Check the activity of the local connection between the computer and the modem (the corresponding indicator on the front panel of the modem should be on);
Check (in particular, the activity of the TCP port and the correctness of the TCP / IP protocol settings for the PC network card);
Ensure that the router is working and that the firewall is working correctly, which should not block traffic flow.
Recheck DHCP options.
If it was not possible to identify the cause of the error, you can apply a more radical method - restoring the system from the last autosave. However, before proceeding with the installation of the backup, you must save to an external media all system changes that have occurred since the creation of the backup (important files and folders, save games, software, etc.)
Error codes when creating dial-up and VPN connections
If you encounter an error while connecting to the Internet, we recommend that you follow the steps in this manual. If these steps did not help, you need to contact technical support, report the error code and list the actions you took.

This error occurs due to a "hang" connection. Restarting the computer helps to eliminate it.
Error 635- an unknown error has occurred. This error occurs due to problems with the VPN client on your computer, it is either corrupted or not installed correctly. Typically, this problem can occur on older Windows 95/98 operating systems. To solve the problem, you need to reinstall the VPN client (also known as Virtual Private Network) or Windows.
Error 638, 651, 769- errors are found in all types of equipment, consider the typical actions that can help in resolving them:
Check if the modem is properly connected to the computer.
Check for power on your modem (for modems with external power supply).
If you have a modem connected to a USB port, check if the drivers for the USB ports are installed correctly in the operating system, it is better to install the "native" drivers that come with motherboard.
Check in "Device Manager" under "Network Cards" that the modem driver is installed correctly. If you have a modem connected to an Ethernet port, check the driver settings for the network card installed on your computer.
Check if the TCP / IP parameters are set correctly for the network card installed on your computer:
Check the type of cable used when connecting the modem to the computer (use the cables from the purchased kit to connect).
Check the connection between the computer and the modem by means of the modem indication.
Check the connection between the computer and the modem using the ping command in the command line (Start / Run / cmd command), to the TCP / IP address set on your modem (ping 192.168.1.1)
Check if the modem parameters are correctly set according to the instructions supplied on the CD-ROM from the equipment set.
Check if the connection parameters are correctly set according to the instructions supplied on the CD-ROM supplied with the equipment.
If you need WinPoET to establish a connection, install it. WinPoET is used in Windows ME, Windows 2000 operating systems.
Check the presence of the DSL signal by means of the modem indication, the corresponding indicator on the modem should be on constantly.
For most USB modems, the indication on the modem is duplicated by the software indication.
If there is no signal, check if the connection is correct.

In the properties of the vpn connection, open the "network" tab - in the "VPN type:" list, select "PPTP VPN"; try to connect.
Error 797-the connection to the remote computer could not be established due to the fact that the modem is not found or is busy
Probable reasons - the modem is frozen, the modem driver is not installed. The connection for Internet access is incorrectly configured, the modem is faulty. Possible solutions - restart your computer if you have a USB modem, reinstall the modem driver, re-create the high-speed connection, if the modem is faulty, contact the service center.
Errors with codes 8XX
Error 800- absence and / or network problems. Problems, both on the side of the provider and the client.
Causes:
Error 652- could not connect to the network due to the existence of matching names.
Possible solutions: try changing the computer name in the network properties (Windows 98 / ME) or the properties of "My computer" (Windows 2000 / XP), you can also try to check the network components, if Microsoft Loopback Adapter is installed - remove it (in the Russian version " The Microsoft Loopback Adapter "is a virtual network card, or rather, it's just a driver). If this does not help, you need to figure it out on your computer.
By default, from a laptop or computer when using a Wi-Fi connection, the Internet and the network should connect automatically. The user does not have to think about what and where to include, as when working with a wired Internet.
Here one of the main advantages of this connection is the ability to turn on from the first second, without waiting.
But it also happens that it was not possible to automatically connect to the proxy server. What it looks like and what to do for a simple beginner in the Internet community in this case. The reason for this problem is hidden in the settings for connecting to the proxy server. You could change them:
The complexity of such problems is that with the Internet connected, which will look like it is turned on in the command line, and even torrents will work and Skype can work, but it will become impossible to start working in any window. It will open but not load. Everywhere it will be written that there is no connection to the proxy server.
The signature can be in English, in Russian. Only one tab or different browsers may not open. Or maybe such an error occurs in all browsers.
There is no connection to the proxy server, which means that somewhere the automatic connection to the network is broken, which does not require human intervention.
No connection to the server
An important note - automatic connection problems have nothing to do with the operating system (OS). Therefore, there can be no problems here. The difference will be small only in fixing such a problem on different operating systems -7, or 8, or 10.
In this case, the main thing is not to be hysterical, not to say that repairs will cost a lot of money. And it is not necessary, in a fit of imbalance and with a hot head, to start with:
To fix proxy connection errors in any browser, the first thing a user should find is simple Settings.
After clicking the button, a window with settings opens. But not all of them may be displayed. Therefore, the user needs to look at the window, and if there is nothing with the signature of the proxy server, click the Change proxy server settings button. Then the user will see on the screen a window in which you should already choose to change the Internet settings.
It will automatically open on the connection parameter (if not, you need to select it) and then click the button - Network settings.
After that, in a new window, the user must check the box for automatic detection of parameters and click ok to fix the connection.
And then the apply button is pressed and you can check the error correction. Mozilla works in a similar way. But the end of the procedure is slightly different. Through Settings, there are Advanced, then Networks and there you can already select Configure. Be sure to select the item WITHOUT PROXY. It will be better this way.
After the user has corrected the settings for disconnecting to the network in all browsers, you need to refresh the connection through Windows. For this, the following sequence of actions is performed:
And now you can try to correct the automatic connection to networks using the tools available in the OS. To do this, select Start, then Control Panel and Network Control Center.
Network Control Center
Then you need to select - change adapter settings. Then there you will need to move the mouse to the "local area connection" shortcut and select properties after right-clicking.
In the connection to the local network, in the Networks tab, check the box or select the line Internet Protocol Version 4 (TCP / IPv4)... And, as always, click OK.
Then you need to make this line with the connection active, stand on it, and click the Properties button, which is just below. A new window will appear. Both IP and DNS addresses must be automatically selected in it.
Just in case, you can still run through command line the next phrase is ipconfig / flushdns. But this requires administrator rights.
Things will get worse if automatic settings flew due to a failure, blackout or not completely cleaned virus. Then the computer will have to be "cured". Due to a virus, settings can fail in two cases:
You can fix such errors with the same antivirus. But the program should be simpler so that it does not intrude into the settings, for example, this AVZ.
In this program, you should select the restoration of system settings through the "File" and put all the checkmarks, exactly as in the figure below. Then you should click to perform the marked operations.
After that, you can reload the browser and try to see if the Internet pages open.
As for the anti-virus programs themselves, in this case it is better to use one-time scanners, without permanent installation on the computer. It can be:
Another option to fix automatic connection is clean up registries.
In the operating line of the OS window, type HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ WindowsNT \ CurrentVersion \ Windows \
In the window that opens, you need to check the folder or file Appinit_DLLs. There should be nothing in it!
In version 10 of the OS, this file will be named AutoAdminLogan.
All possible options for fixing the connection to the proxy server have been sorted out. If all else fails, then you should call the wizard. It means that something more serious has happened to the computer than the settings that have flown off.
Another problem with connecting to networks and working in social networks... Very often, when loading sites on the Internet, an annoying window appears with the following content:
Connection failed error
The same error is very often referred to on the network as the connectionfailure error. Such inaccuracies should be remembered when searching. This is just that magical option, when you can enter some sites, but knocks out such a mistake on others. There are probably no reasons for the virus. In most cases, this problem is caused by:
To solve the problem with the firewall, you will have to turn the brandmauer on and off. In case of blocking sites due to the enabled antivirus, you will have to disable such blocking on the antivirus. This is how it might look on Avast. All you need to do is update your antivirus to remove blocking links.
Updating signatures
And if there is no truth in any of the proposed options, then all that remains is to call the provider and find out if preventive work is being carried out somewhere. And there is such an option that they cut the wires in the yard or the user did not pay for the services.
Connecting a computer or laptop to the network can be done in two ways:
But besides these nuances, there is also a type of operating system that needs to be taken into account. And if the seven and eight with modifications are similar to each other, then the top ten may have their own difficulties.
How to connect an Internet connection via a wired cable and via a wireless network for Windows 7 is published in great detail and is officially available on the Windows website. You need to connect version 8 to the Internet in about the same way.
Thus, the user will not be confused and not lost if the computer suddenly starts cursing about inaccessible pages. It will be enough to first try all of the above methods on your own, and only then go to the workshop.
Windows 10 users sometimes get error 651 and the like when they connect. These are called "internet connection errors". This is due to the appearance of a software or hardware network hardware failure.
To restore the operation of the OS, you should find out the reason for the failure. This error appears when:
There are some common simple options for fixing Windows 10 internet connection error:
First you need to find out that your local network connection is working. The window opens first "Network connections"... There you need to select an item Enternet where there are items such as:
The user needs to check the state of the LAN, it has several values:
Simple troubleshooting steps:
Correction of the error that appeared as a result of connecting through a router (modem)
When the Internet cable is connected to the router, and the router and PC are connected via Wi-Fi, there is no need to start a high-speed connection.
In this situation, a high-speed connection will not work and error 651 will appear on the monitor screen. For normal operation of the Internet, it is already enough that the PC is connected to the router and no other connection is required. In this case, you need to configure the router and create a connection. To do this, he needs to specify the type of connection, his name, password and other required information.
After the performed actions, the router will start working and distribute the Internet to all gadgets. No extra connections needed. An important task in the work of the Internet is to correctly configure the router / modem. This will help the instructions that come with the device.
Let's consider several reasons when the connection is made via an RJ 45 connector:
Sometimes dust accumulates in the tip, for normal operation of the device it can simply be blown out. Sometimes, in order to reconnect to the Internet, you just need to unplug the RJ and then plug it back in. Malfunctions can be caused by deformation of the wire.
Quite a popular reason for a connection problem. In this case, it is better to create a high-speed connection:
Then the user needs to click on the button "To plug"... If the methods turn out to be useless when trying to eliminate error 651, then the cause of the malfunction may be incorrect operation of the antivirus program or firewall.
To fix the problem, you must shut down the systems and try to connect to the Internet. First of all, to establish a connection, you need to disable the antivirus. Each user has his own antivirus installed and to disable it, you need to read the instruction manual. Then you should turn off the standard firewall - a set of software tools that monitors the launch of programs on the PC that access the Internet.
This error is also common if a router is connected. You can cope with it like this:
And download the program that resets the protocol settings. To do this, you need to click on the specified link. At the bottom there are two buttons called "Download". For the Windows 10 operating system, you need to click on the second button. When the program is downloaded, the user needs to launch it and restart the PC at the end of the procedure.
In this case, there is most likely a driver issue. They may either not work correctly or become outdated. The user needs to update the drivers. To do this you need to enter "Control Panel", in the line that appears, enter "Device Manager".
A list appears showing the devices. Of them is selected "Updating Device Drivers"... Then the dispatcher will appear, and the item is selected in it. "Network adapters"... After that, you need to select your adapter and click with the mouse (right button) on the item "Update Drivers"... Then you need to follow the instructions of the guide.
Sometimes, when using all methods, the error does not disappear. This happens due to a malfunction of the router. Then it is worth checking the operation of the modem on another computer.
