What should I do if I get an Error Password or Username when using a broadband connection at home?

This problem is either that you got the password wrong, or that you just caused a short circuit in the network cable for no reason, that is to say, you can't log in in a short time, because you still show ** on the network cable host, that is.

Busy. Now, try it in a few minutes, and if it still doesn't work, go to the place where you handled the network cable and change the password. Ask to bring your ID card or a copy of your ID card, and fill out an application form, which will be done in about 5 minutes.

First, check if there is still a charge for your broadband.

Second, delete the broadband connection and try to create a new broadband connection.

Again, call your operator to verify whether your password has been tampered with, and by the way, ask them to check if they have logged in elsewhere during the time you are not online.

Call your local broadband company, they will generally come to the door to serve, if you don't know their **, you can call the 114 number check desk first, there will be registration, and then you tell them the situation, they will solve it.

The username and password are only required when setting up the router, and the point broadband connection does not need to be entered only for the contact connection. I am from Jiangsu Telecom, and the network may be different from place to place, I hope it will be helpful to you.

Check with your carrier to see if broadband is available.

Check whether the username and password are correct.

Tool Material: Computer.

The password of the broadband connection is incorrect, the solution to change the password:

Go to the router's server and select "Wireless Settings" - Wireless Security.

In wireless security, enter the password you want to change in the PSK password column, and finally click Save by dropping down.

After the password is successfully changed, click Save to reconnect to the broadband and enter the password.

Workaround for the wrong username or password for your broadband connection:

1. Delete the username and password and re-enter it again, paying attention to case sensitivity.

2. Restart the computer and reconnect to the broadband.

3. Delete the broadband connection and re-establish one.

4. Disable the local connection for one minute, and then enable it.

If there is an error **678, you will have to call the operator**, and let the operator adjust it for you on the server side.

Didn't you enter a password?

Is it supposed to be a password mistyped, a new broadband?

1. First of all, you need to delete the broadband connection between the desktop and the online neighbor.

Other reasons for error 691:

1. Account arrears: After ADSL broadband users are 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. (The account arrears may be due to the overdue broadband payment and shutdown, or it may be the number of the combined account, the user who has expired the broadband can renew the broadband, and the user who is in arrears of the combined account code can pay the arrears of the combined account code.)

2. After the computer disables the network card or the network card is not driven or the driver is wrong, a prompt of 691 will also appear, check whether the network card is working normally.

3. Use a VPN to deny access due to an invalid username and password on the domain.

4. If you have a problem with the setting of the modem modem, contact the operator, and the operator will generally replace this problem free of charge.
