Ubuntu's notebook came to a local area network, plugged in the network cable, the network cable indicator light is on, but does not connect to the Internet, click the network connection icon to display "network unmanaged". I suddenly remembered that this notebook had been set up with PPPOE (Wired Broadband Virtual dialing) not long ago, so I made some setting changes and finally solved the problem.

1. Ubuntu's notebook came to a local area network and was a bit of a stranger. Plug in the network cable, the network cable indicator light is on, but do not connect to the Internet, click the network connection icon to display "network unmanaged". I suddenly remembered that this laptop had been set up with PPPOE (Wired Broadband Virtual dialing) not long ago, and it was suspected that it was the reason.

2. Press Ctrl + Alt + t to call up the terminal.

3. Type the command: cd / etc/network, and change it into the directory / etc/network. There is a file called interfaces in it.

4. Then type the command: sudo gedit interfaces, which means to invoke the gedit text editor and open the file interfaces.

The last line of this file is: iface eth0 inet manual, which means that the eth0 network interface (on personal computers, eth0 generally refers to the only network cable interface), you need to set up the network manually.

5. However, the current local area network is obviously a DHCP network, that is, the connected computer needs to "automatically obtain the network" address. We add the English "#" and "comment" in front of this line of characters, which means not to set the network manually, but to set it automatically. Note that it must be "#" in English, otherwise if you enter Chinese, it will not play the role of "annotation".

6. Save the file, close the gedit text editor, return to the terminal, and type the command: sudo service network-manager restart, which means to restart the network management service. Press enter and the network will be connected immediately. When you leave this local area network and need to re-use virtual dialing, just remove the added "#" according to steps 4 and 5, and then restart the network management service.
