00 means that you can only access the campus network but not the external network, which means that GS has not been opened.

10 is charged by the time, 60 cents per hour. It is more suitable for downloading things, watching videos and pictures, but sometimes the network speed is faster.

68 is an education network cable, which is charged according to the flow, and is more suitable for hanging QQ.

70 is a netcom line and 79 is a telecom line, both of which are charged according to the flow.

The network strategy of Maritime University is abnormal, so I'd better pull a broadband myself if I can.
