Error 691 and others. Problems with connecting to the Internet and ways to solve them

Many users sometimes encounter errors when connecting to the Internet. This can be caused by problems on a particular computer or by faults on the provider side. The error number allows you to find out the reason and find a solution without assistance from the operator's specialists.

Common Mistakes

They can be quite a lot. Most of them are associated with incorrect user settings. Most often, service providers face the following errors: 691, 678, 619, 769, 800. Each of them has different reasons. At the same time, many can be eliminated manually, without seeking help from the provider.

Important! If you can not solve the problem yourself, you should call technical support.

Error 691

Perhaps the most common internet connection error is 691, which indicates that the user name or password is incorrect. It appears during the verification of registration data. Simply put, the error means that the provider's server could not correctly identify the user, or he is denied access to the network.

Causes of Error 691 and Remedies

In fact, the error 691 during connection can occur due to a large number of reasons. Among them:

  • Incorrect username or password;
  • negative balance;
  • Login is already authorized on the server.

Very often when creating a new connection, users receive an error 691 because of incorrect login or password. In order to avoid this problem, it is recommended that you first type the registration data in notepad and copy them to the authorization window.

A negative balance for a number of telecom operators also results in an error 691 appearing on the user's screen. You can solve the problem in this case simply by checking and replenishing the account if necessary. Many providers allow you to enter your personal account and without authorization on the server, and some will have to call for technical support.

When you try to turn on Internet, error 691 is also given to the user, provided that the previous session is not closed. It happens quite often with incorrect disconnection from the Internet. It's enough to wait 5-10 minutes and connect again. If this happens, call technical support.

Important! In Windows 7, connection error 691 is not always displayed. Very often, instead of it, code 692 appears. Therefore, if an error message appears during the verification of the user name and password, you should also follow the steps described above.

Error 678/651/815

Error 691, as mentioned earlier, is not 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 differ. In Windows XP, it will be 678, in Vista - 815, and Windows 7 users will see the 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:

  • Rush cable;
  • Problems with the provider;
  • Errors in the operation of the firewall or antivirus;
  • Incorrect setting of the subscriber unit.

If the error 691 in most cases can be fixed by itself, then when a message with the code 678/651/815 appears, the user can only disable the antivirus and firewall, and also check the cable inside the apartment and the subscriber device (router, optical terminal or modem) .

Important! Carefully check that 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 the error 619 depend on this .

Users who connect using PPPoE, as a rule, can detect it due to a lack of funds on the balance or incorrect input of the user name and password. This type of connection is typical for the following operators: Rostelecom, Dom.ru and some others.

Subscribers using a mobile connection to the Internet via 3G / 4G provided by cellular operators can see the message with code 619 due to problems with the USB modem or the computer port. In this case, you can advise to connect the device to another connector and reinstall the drivers.

Clients of some networks connect to the Internet through a VPN. In this case, error 619 reports incorrect security settings. In the Internet connection properties on the "Security" tab, you must set the parameter "When scanning is used" to the "Secure password" position. This type of connection is used, for example, by home Internet subscribers from "Beeline".

Error 769/800

Windows XP users will receive a message with the code 769 for problems with drivers or with a LAN connection to the network card , and those who have Vista installed are 800.
First of all, you need to check that the connection over the local network is active. You can do this in the "Start" menu in the "Network Neighborhood" section by selecting "Show network connections" or by contacting the "Network Management Center". If the local connection icon is gray, you must enable it using the context menu.

If there is no LAN connection, the problem is with the drivers. They must be reinstalled from the attached disk or downloaded from the manufacturer's website.

Other Errors

When connecting to the Internet, users can receive a message about other types of errors, but they are rare. Eliminate some of them to the user is difficult or even impossible without the help of a specialist.

Consider other errors that often appear when connecting to the Internet, and ways to solve them:

  • Error 734 means that the PPPoE protocol has been completed. As a solution, you can try to re-create the connection.
  • Error 735 means that an incorrect IP address is used to connect. In the network connection settings , you must specify that the network address must be received automatically, or enter the correct parameters from the contract with the provider.

In any case, if you can not solve the problem yourself, you need to call the technical support phone. The specialist of the company will tell you the possible causes of errors and ways to eliminate them. And, if necessary, also make an application for the departure of fitters.
