We list the causes of error 691:

1. Invalid credentials entered.
2. Insufficient funds on the client's personal account.
3. Firewall is blocking outgoing connection with Internet Service Provider equipment.
4. Invalid VPN server IP address of the provider.

There are several ways to solve the "Connection Failed: Error 691" problem.

How to fix error 691

Depending on the cause of the problem, a solution should be applied. Below are the main methods detailed instructions. Explanations are also given in which cases this error occurred.

Checking the correctness of the login and password

The most common occurrence is incorrectly specified credentials.

Error 691 occurs when a user fills in their credentials when connecting to the Internet in Windows 8.

We immediately check the character input language and whether CapsLock is enabled. We delete the information we just entered, and then we try to enter it again.

Important point! The password is case-sensitive, that is, capital and small letters are two different characters.

Quite often, error 691 occurs at Rostelecom, as the provider comes up with complex passwords for clients.

It is also worth checking that the item “ Secure Entry". To do this, in the connection properties, go to the "Security" tab and check the setting of this parameter.

Balance check

Another common variant of the error in question is negative balance on the client's account. To check your account, you need to log in Personal Area. With a minus on the balance sheet, it is enough just to replenish it.

Error 691 in such situations appears at the very first stage of connecting to the Internet, for example, in Windows 10.

Internet connection problems also occur due to the network device. For example, on the routers of the provider “Dom. ru" error 691 appears due to old version device firmware when connected to the World Wide Web.

In this situation, there are two options.

1. The first is to reboot the router and try to connect again.
2. The second is to update the revision of the network device to the latest version.

In the second case, you will need to go to the official website of the manufacturer, and then download current version revisions. The update process can be started using the router's web interface. After updating the router, you will need to reboot and set the settings to the Internet again.

Checking the activity of a wi-fi adapter

Error 691 often occurs on a computer under Windows control XP when using an external Wi-Fi adapter. This is because the operating system does not support most network cards, and there are no suitable drivers for them.

To check the performance of the device, it is recommended to use the applications on mobile devices, for example, wi-fi Analyzer.

After starting the utility, you will need to select wireless network. The program will scan the range of wi-fi, the main characteristics of the connection and present the result in the form of a graph on the smartphone screen.

If the user's device shows excellent signal strength, but the computer is not communicating, then the problem is wireless adapter. It may be out of order or it has problems with the drivers.

In the first case, it is worth buying a new one, and the second option will be discussed below in the “Updating Network Card Drivers” section.

Error 691 also occurs due to firewall policies regarding incoming traffic using and connecting Windows 7 connection. The firewall is able to falsely block outgoing / incoming connections, which, in turn, leads to blocking communication with the provider's server.

To fix this situation, you need to go into the security settings of the firewall and add the address of the server of the Internet service provider to the exceptions.

After that, we check the availability of global network.

Antivirus

Antivirus applications also falsely work and block the files responsible for establishing a connection to the Internet. For example, the technical support of the TTK provider promptly resolves issues related to error 691, advising its customers to disable the antivirus. After that, it is recommended to re-establish the connection.

If everything works fine, it is worth checking the antivirus settings software(ON). To connect to the World Wide Web, add the necessary processes to the exception.

Update network card drivers

The appearance of error 691 when connecting to the Internet from a service provider, for example, ByFly, is due to outdated drivers for the network card.

Driver updates can be made using special software sdi tools. Download link: https://sdi-tool.org/download/ .

The application is presented in two versions: Full and Lite. The first option assumes that the user downloads the entire database of available drivers on local disk. After that, you need to run the program, and it automatically updates everything that is needed.

In the second case, the user downloads only the utility. After its launch, it will offer to download from the client's equipment.

The installation will not take long, but at the end you will need to restart your workstation.

Recreate the connection

Another option to fix problem situations with different error codes 691 is to re-create an Internet connection.

The user will need to select a protocol to create the connection, such as PPPoE. And also specify the credentials provided by the provider.

After that, you should check your internet connection.

VPN setup

Separately, it is worth mentioning the types of connections using the provider's VPN server. A well-known service provider that has error 691 is Beeline. The connection uses the L2TP protocol.

Before contacting the service technical support provider, the user can independently check the configuration. For this:

In recent years, service providers using the L2TP or PPTP protocols have begun to prescribe the receipt of the server address automatically. This was done specifically for an easier process of setting up a connection to the "world wide web"

A variant of faulty equipment on the provider's side is also possible. In this case, you should contact the technical support of your Internet service provider. Most likely, the equipment is temporarily out of order, and specialists are correcting the situation.
