To make a simple and understandable instruction, I will divide this article into two sections: the solution of this error when connecting to the Internet via a router (modem), and with a direct connection of the cable from the provider to the computer. But first I want to give a few simple, general tips that will probably help get rid of the error with the launch of a high-speed connection.
- Call in support of your Internet provider, inform them about the error 651. Ask if there are any problems on their side. Simply, this error often occurs due to problems in the equipment provider. And before changing any settings at home, it would be good to make sure that there are no problems at the other end of the cable.
- Disconnect the network cable from the computer, router, modem and reconnect. Try restarting the high-speed connection.
- Restart your computer. Also, reboot the router, or modem (if it is) . Just turn off the power for a minute, and turn it back on.
- If this error occurs during the configuration of the connection to the provider, the first time you start, then most likely you just incorrectly specified some settings when creating a high-speed connection. Check all parameters that you entered. If you do not know something, you can call in support of the provider.
- Recall that you changed, installed, or configured before the error 651. An antivirus could be installed that can block the connection. Try to temporarily disable it.
- If you have two network cards in your computer, disable one. Leave only the one through which you are trying to connect to the Internet. You can simply disable the adapter in network connections.
If these recommendations did not help, and you still can not connect to the Internet through a high-speed connection, then you need to check other solutions more complex. Below I will try to clarify the situation with the error "The modem or other communication device reported an error" when you have the Internet connected through a router or modem, and when you directly connect the cable to the network card of your computer or laptop.
If error 651 appears when connecting through a router (modem)
This is generally a separate story. Here it is important to understand one thing: if you have a cable from an ISP connected to a router, and a router with a computer is connected by a network cable, or over Wi-Fi, then the computer does not need to start a high-speed connection at all . It just does not make sense. Is that the router you have settings in bridge mode (Bridge). I'll explain now.
Virtually all routers work in Router mode by default. And when the Internet is connected to the router, and you start the high-speed connection on the computer, it will not go through the router. And you will see error 651. This is normal. Why do you need to start the connection on the computer, if you installed a router. The router itself will establish a connection with the provider using the PPPoE protocol. It is necessary only in the settings of the router to configure this connection. Select the type of connection, set the user name, password, and so on.
The router will call the provider, connect to the Internet, and will simply distribute it to all devices via cable and over Wi-Fi. A high-speed connection to the computer just does not need. It can be deleted.
If you still want to start an Internet connection on the computer through the router, then you need to switch the router to Bridge mode. However, I do not understand why.
