After setting it correctly according to the above method, you still can't access the Internet, please check your network cable (for example, find a notebook to plug it in and see if you can access the Internet)!

Error 678 is not that the network card is not installed, but that the remote computer does not reflect. There are probably several reasons: 1 is that your cat has a route, you don't need to dial up, set the IP address, it's good, 2, your network cable is wrong, 3, your network card is broken.

It should be that the network card driver has not been reinstalled, and it is recommended to install the driver (my home is a floppy disk).

Restart the cat. Check the network cable connection. Check the username and password, set the dialing attributes, and set the "pulse" to "audio".

It doesn't matter, if you use your own ** help, just call 10000 and ask them to restore the initial password for you, and then re-establish the connection.

Is there a problem with the network card? Is the network cable plugged in? ADSL cat is turned on.

I've been in this situation. You're only checking the line at home, maybe there's a problem with the network line outside. It may be that the cable was cut off during repairs outside.

If it was okay before, and it only appeared after reinstalling the system, then you check whether the driver of the network card is installed normally.

678 is not a problem with the network cable, and the error message 678 means that the remote computer is not responding. That is, the carrier does not respond to your dialing request.

1. Is the router set up for filtering?

2. The IP address is not automatically obtained?

Try installing the NIC version of the driver wizard.

How many errors? For example, 691 is because you entered your username and password incorrectly.

You open the Device Manager to see if the NIC driver is not installed.
