Error 691 means that the username or password on the domain is invalid and access is denied. This can be solved by checking the username and password.

Error 691 is a fault message that is commonly encountered by broadband ADSL dial-up Internet users. Broadband ADSL dial-up Internet access uses PPPoE protocol connection, transmits data through ** line, and uses ADSL dedicated modem to realize data modem, prompting error 691 In a real sense, it may be due to the following reasons:

1. There is an error in the domain name (the username or password is entered incorrectly);

2. ** or due to overdue broadband payments;

3. The server does not respond (the user port in the computer room is wrong, or the account is not activated);

4. Hardware failure.

The computer displays 691, which is a type of error that broadband users often encounter, mainly due to domain name error, broadband arrears, or hardware failure. Here's how to fix it:

1. First open the settings, find the Network & Internet option, click to enter, and find the dial.

2. Under the dial-up interface, click "Set up a new connection" and select "Connect to Internet" in the pop-up options.

Broadband 691 Error:

1. Arrears. I usually think about this first when I get a 691 error, because this is the most common and easiest to fix. You only need to check whether your account is in arrears, and if you are in arrears, you can connect to it after recharging, and if it is not in arrears, consider other reasons.

2. The username or password is incorrect.

This is not very common, if it is dial-up Internet access, you will basically choose to save the password, but it is also possible that someone else will move it, so re-enter the account and password to try, if you can't solve it, you have to consider other reasons.

3. The MAC address is incorrect.

This is not common, often it will appear when two network cards are installed on the computer, and it is enough to disable one.

4. The account is stolen.

This is actually a small category of user password errors, the reason why he is listed is that if you are sure that your username and password are not wrong, it is possible that someone else has reset the password, so you have to call ** to the network operator to reset the password.

Workaround for error 691:

1. When the fault fails, it must be carefully judged, and it is difficult to distinguish the case of the account password and the spaces before and after the account. Therefore, when a 691 error occurs, you can try to delete the original account and password and re-enter the correct account and password.

2. Account arrears: After the ADSL broadband user is in arrears, the broadband access service provider will temporarily suspend the account, and the account may not be activated immediately after the user pays off the arrears, and if the number is dialed, there will also be a prompt with error 691.

3. The broadband service provider limits the number of your account use, if someone else is using your account, your dialing is error 691, please check the number of people who use this account at the same time.

4. It is best to use an account only on the port you apply for, if it is brought to another **port, error 691 may be prompted.

5. For some reason, the account is disconnected abnormally, for example, the computer suddenly loses power. The server is still disconnected, and your user is still logged in, similar to the situation above, so error 691.

In this case, you only need to restart the computer and model modem, and try again after 5-10 minutes.

6. After the computer disables the network card or the network card is not driven normally, there will also be a prompt of 691, check whether the network card is working normally.

7. User data binding error: In order to better serve the user and ensure the security of the user account, the broadband service provider binds the broadband account and the user's physical port, and the number also makes a one-to-one binding, so that the account can only be used on a physical port (i.e., the roaming of the ADSL account is restricted), and a port is limited to one computer to access the Internet, if the user's data is bound incorrectly, the error 691 will also appear when dialing.

8. When two local network cards are installed on the computer and enabled at the same time. If the MAC address is bound incorrectly, error 691** appears, and it is recommended to disable one of the NICs.

The account number and password do not match, I have encountered this situation before, I am using someone else's account, and the other party changed the password with the provincial card, and I encountered it, sad and urging.

Broadband connection error 691 is generally caused by the password and broadband account, since you are certainly not caused by the wrong password, and your account can be used if you change the computer, here I ask you, the computer you changed is still connected to the original cat and network cable? If it is, then it is definitely a problem with your computer, and your cat and wiring are all good. First delete the broadband connection, create a new one, and type the password out in the notepad to see if it is the same as you want to type (sometimes some letters in the notebook are numbered).

If it's not your cat, it's probably your line or your cat is a problem.
