How to use the USB cable interface to log on to the campus network on the MacBook

Looking forward to, looking forward to, the new computer MacBook came, but the thin Mac does not have a network interface, and the school campus network wireless speed is very slow, how to do?

Had to buy an external USB adapter (I would say that the MacBook built-in lightning adapter is too expensive?) ), the hardships received goods, plug in the network cable ... The results show:

"USB 10/100 LAN" has a self-assigned IP address and will not be able to access the Internet. "

Hang Daddy! Why is there an automatically assigned IP address that cannot be connected to the network? And the following DNS is incredibly empty ...

So, in the era of Google was wall-down, or ask Baidu ...

1. Remove the re-insert, ........ Re-inserted n times, n is greater than or equal to 6;

PPPoE, full name is Point-to-Point Protocol over Ethernet, meaning "Ethernet-based point-to-Point Protocol". the intention is to deal with the Ipv4 of the exhaustion of the dynamic allocation of IP, while it can eliminate the trouble of manually configuring the network, so you can use it to let remote centralized devices to help us automatically configure.

Open Network Preferences, lower left corner "+" Add new network--Interface Select PPPoE, Ethernet select USB 10/100 LAN, service name default PPPoE. And then create.

After the PPPoE service name, account, password, I fill in Tju_pppoe, 30xxxxxxx7 (my account), xxxxxxxxxxxxxxxxx (my password).

Click to connect , nice ...
