Since there is no network cable interface on the MacBook Pro, you must first prepare an adapter
Specific steps are as follows
-
Open System Preferences - Network
-
Click the plus sign in the lower left corner to create a new service.
-
Select PPPoE for the interface, and the service name can be arbitrary. After completion, click Create
4. Enter the account name and password and click Connect
In addition, if the USB shows that it is not connected after plugging in the network cable, it may not be a problem with your computer. Is there a possibility that the network cable interface on the wall is broken?
Yes, that’s the case for me. I’ve been tinkering all day long, trying to install external network card drivers and so on, but nothing works. So I unscrewed the screws on the network cable interface on the wall, and finally discovered that the network cable inside was broken. . .
The solution is to go to the campus network to report for repairs, and then a switch was sent to me, and I used it to connect to the network cable interface on the wall of my roommate. My roommate and I both used network cables to connect to the switch. Okay, it’s really not easy!
