What happens when the computer can t connect to the network and shows 691?

691 You should use PPPOE dial-up Internet access, this problem arises, mainly:

The username and password you entered is invalid, which means that the username and password in your broadband connection are incorrect.

Usually due to carelessness, the broadband account number or password is entered incorrectly.

The second possibility is that you didn't make a mistake, but the broadband connection went wrong for some reason and you won't get it right no matter how you type.

The third possibility is that your local operator has set up address binding, and if you change computers to access the Internet, there will also be a 691 error.

Fourth, there is a problem with the RADIUS device of the carrier, which is generally rare.

However, in short, the appearance of 691 is generally not a big problem, and you don't need to be too single-minded, which basically means that your link is normal. The appearance of 691 still proves that you can link to the carrier's device, and you are only one step away from surfing the Internet. Don't be nervous.

You can call your carrier to see your account status. It's almost certain.

1. The reasons for error 691 are generally: 1. The username or password is entered incorrectly; 2. Broadband arrears when due; 3. The server does not respond, (the user port in the computer room is wrong, or the account is not activated); 4. Hardware failure.

2. If the username or password is entered incorrectly, the original account number and password will be deleted, and the correct account number and password will be re-entered. If that doesn't work, you can call your broadband service provider to check the user and password.

3. Broadband payments are in arrears when they expire. Account arrears: If an ADSL broadband user becomes in arrears, the broadband access service provider will temporarily deactivate the account, and the account may not be activated immediately after the user pays off the arrears, and error 691 will also appear if the user dials up.

Fourth, the server does not respond, (the user port in the computer room is wrong, or the account is not activated) sometimes when the computer suddenly loses power, there will also be this error, after booting, just wait for 10 minutes, it may be automatically solved.

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

Sixth, the cat (modem) modem setting problems, and the operator contact, generally this problem operator free of charge.

1.If the account password is wrong, it is recommended to re-enter the account password to connect, or call the telecom customer service 10000 to reset the password.

2.If you are in arrears, call 10,000 customer service to check whether your broadband account is in arrears.

3.The account is logged in repeatedly, that is, it is out of sync with the server time, this time misalignment phenomenon is recommended to turn off the cat, open the cat after 5 minutes, connect again, and let the server confirm that the account is offline through this time, and calibrate the time.

4.If the above methods can not be solved, it is recommended to check the networking equipment, see if the network cable interface is plugged in, try to see if your broadband account can be logged in on someone else's computer, pay attention to the computer must be the same operator as you, such as the access to the telecommunications network or Netcom network, so that you can try it on someone else's computer, if you can log in on someone else's computer, then there are only two situations, networking equipment problems and system problems. At this time, use someone else's cat and network cable to connect to your computer to see if you can access the Internet, if it can be your cat and network cable problems, please replace the network cable or cat.

If you can't access the Internet, it means that it is a system problem, please check the NIC driver. If the drive is normal, it may be that the system files are missing, first use the 360 system first aid kit to recover the system files, if the recovery is invalid, or can not access the Internet, it is recommended to reinstall the system.

Error 691 is that your account password is wrong, it is not a cat problem, and it is not a connection problem, you need to contact the customer service of the communication company and reset a password.

Repeat the login, wait a while, or restart the modem.

691 is a connection problem, you see if the network cable is not connected well, and whether the router is powered normally.

Just solved this problem, I deleted the system files by mistake, and I just reinstalled the computer system once.
