The computer is not connected to the Internet Error 691 is displayed The username and password are i

Telecom limits the number of accounts you can use, for example, your account can be used by 4 people, and now 4 people are using it, and you dial error 691

You didn't disconnect after using it, at least the server side still didn't disconnect, thinking you were still using it, similar to the situation above, so error 691

The second is that if you reinstall the system or change the network card, or even change the machine, you need to re-verify your identity because the broadband service is bound to the computer.

Third, don't steal your account, because the broadband service of China Telecom Netcom has a limit on the number of connected users.

Fourth, the operator's server is faulty.

You try to rebuild a broadband connection. I have the same symptoms as you. I don't know what the reason is, but it's normal after the reconstruction. You try it.

Restart the machine and try it, if it doesn't work, it means that a file on your C drive has been deleted.

Restart the machine and see if the system is broken.

Hello friends;

If the broadband connection has an error indication of 691, it is usually due to the following reasons:

The first reason: the username and password are filled in incorrectly, and you can fill them in again.

The second reason: there is a problem with the port of the broadband computer room: the server does not reflect, (the user port of the computer room is wrong, or the account is not activated) Generally, it is necessary to call the network provider to let the computer room adjust the port or redo the data packet.

The third reason: ** or due to the overdue broadband payment, so it is necessary to pay the ** fee and network fee in time.

Fourth reason: (1.)Telecom limits the number of broadband accounts, for example, this account can be used by 4 people, and now 4 people are using it, and the fifth person is dialing in error 691 (2) I didn't disconnect after using it, at least the server side is still not disconnected, I think it's still in use, and the situation is similar to the above, so error 691 suggests:

Every time you turn off the device, right-click on the broadband connection and click Disconnect

The fifth reason: that is, the adsl cat appears to block the packet, leading to not knowing the account and password, as long as the adsl above the restart twist, press for 6 seconds and do not let go, and then re-plug the network line and ** line on the cat.

The sixth reason: it is also a special reason: the MAC address of the network card is bound to the router. Solution: Where to re-enter the router, tie your MAC address in, the problem is solved.

The seventh reason is that the router is attacked by DDS, resulting in no network, and the indicator is 691. Handling Scheme:

First of all, the data of the wireless router must be cleared, which is to press the restart twist on the wireless router, so that the wireless router will restore the factory value, and then use a smartphone or a computer (whether it is a desktop or a notebook), and then enter in the address bar of the browser: or, the network segment is different, the input is different, and the label behind the wireless router is the main, but the former is the majority. Then a dialog box will pop up, on this box you are asked to enter the username and password, the general username and password are admin, (this wireless router is also marked above), the modern wireless router in this step is to ask you to set a password, and then enter the router settings interface, find the Internet settings or interface settings, according to the setup wizard, select the PPPOE mode, and then enter your Internet account and Internet password, Then set the wireless parameters WPA2 mode and wifi password in the wireless network settings, and finally click Save, so that the wireless router will automatically restart, which means that the setting is successful.

Hope it helps, happy to you!

Lately, I've been turning off my cat's power a lot, especially at night.

Later discovered.

The cat is powered off and turned on again, sometimes 3 times before it is normal, I don't know if it is a factor of the host of the network room.

After connecting normally, try not to let the cat lose power at night. This will not be the case!
