Many users sometimes encounter errors when connecting to the Internet. This may be caused by problems on a particular computer or malfunctions on the provider's side. The error number allows you to find out the cause and find a solution without the help of the operator’s specialists.
The most common mistakes
There can be quite a lot of them. Most of them are associated with incorrect user settings. Most often, subscribers of providers face the following errors: 691, 678, 619, 769, 800. Each of them has different reasons. At the same time, many can be eliminated with one's own hands without resorting to the provider for help.
Important! If you cannot solve the problem yourself, you need to call technical support.
Error 691
Perhaps the most common Internet connection error is 691, which indicates that
the username or password is incorrect. It appears at the stage of verification of registration data. Simply put, an error means that the provider’s server could not correctly identify the user, or was denied access to the network.
Causes of Error 691 and Remedies
In fact, error 691 during connection can occur due to a sufficiently large number of reasons. Among them:
- Username or password entered incorrectly
- negative balance;
- login is already authorized on the server.
Very often when creating a new connection, users receive error 691 due to an incorrect login or password. In order to avoid this problem, it is recommended to first enter the registration data in notepad and copy them to the authorization window.
The negative balance of a number of telecom operators also leads to the error 691 appearing on the user's screen. In this case, the problem can be solved simply by checking and replenishing the account if necessary. Many providers are allowed to enter their personal account without authorization on the server, and some will have to call technical support.
When you try to turn on the Internet, error 691 is issued to the user also provided that the previous session is not closed. This happens quite rarely with an incorrect disconnection from the Internet. It is enough to wait 5-10 minutes and connect again. If the connection happens, then you should call the technical support operators.
Important! In Windows 7, a connection error 691 is not always shown. Very often, code 692 appears instead of it. Therefore, if an error message appears while checking the username and password, you should also follow the steps described above.
Error 678/651/815
Error 691, as mentioned earlier, is far from the only one that occurs when users try to connect to the Internet. Another common problem is the lack of a server response. In different versions of the operating system, the error code may vary. In Windows XP, it will be 678, in Vista - 815, and Windows 7 users will see a message with error number 651.
Causes of error 678/651/815 and its elimination
Error 678/651/815 has a huge number of possible causes. Among them:
- cable rush;
- problems with the provider;
- errors in the firewall or antivirus;
- Incorrect configuration of the subscriber device.
If error 691 in most cases can be fixed independently, then when a message with code 678/651/815 appears, the user can only disable antiviruses and firewalls, as well as check the cable inside the apartment and the subscriber’s device (router, optical terminal or modem), if any .
Important! Carefully check if the network cable is connected to the computer . This elementary thing is the most common cause of errors 678/651/815.
Error 619
The technology of connecting subscribers from different providers is somewhat different. The causes of error 619 depend on this .
Users connecting using PPPoE, as a rule, can detect it due to lack of funds on the balance sheet or incorrect user name and password. This type of connection is typical for the following operators: Rostelecom, Dom.ru and a number of others.
Subscribers using a mobile Internet connection via 3G / 4G provided by mobile operators may see message with code 619 due to problems with a USB modem or computer port. In this case, you can advise connecting the device to another connector and reinstalling the drivers.
Some network clients connect to the Internet through a VPN. In this case, error 619 reports incorrect security settings. In the properties of the Internet connection on the "Security" tab, you must set the "When scanning is used" parameter to the "Secure password" position. This type of connection is used, for example, by subscribers of home Internet from Beeline.
Error 769/800
Windows XP users with a driver problem or with a local network connection will receive a message with the code 769 on the network card , and those with Vista installed will receive a 800.
First of all, you need to check that the LAN connection is active. You can do this in the "Start" menu in the "Network Places" section, by selecting "Display Network Connections" or by contacting the "Network Control Center". If the local connection icon is gray, then it must be enabled using the context menu.
If there is no LAN connection, the problem is with the drivers. They must be reinstalled from the supplied disc or downloaded from the manufacturer’s website.
Other bugs
When connected to the Internet, users can receive a message about other types of errors, but they are quite rare. It is quite difficult or even impossible for the user to eliminate some of them without the help of a specialist.
Consider other errors that often appear when connecting to the Internet, and how to solve them:
- Error 734 means the PPPoE protocol has been completed. As a solution, you can try to recreate the connection.
- Error 735 means that the wrong IP address is used for the connection. In the network connection settings , you must specify that the network address must be obtained automatically, or enter the correct parameters from the contract with the provider.
In any case, if you can’t fix the problem yourself, you need to call technical support. A company specialist will tell you the possible causes of errors and how to resolve them. And if necessary, also draw up an application for the departure of installers.
