First, you have to log on to the campus network and apply for an IP address. You can apply on any computer in the campus network. You can't apply in the external network, you can also apply directly in the network center, but it's best to apply yourself. The people in the network center are so NB that they all think of themselves as uncles. You need to fill in the bed number of your dormitory, and so on. Then, go to the second floor of the bell tower to brush the internet fee. The time is usually from 8: 30 a.m. to 1 1: 30 and from 2: 30 p.m. to 5: 00 p.m., but it's best to walk in the middle, because people leave late and early. 70 for the first month, and then 20 every month. After paying the internet access fee, you can go to the network center to ask for the network cable, but you should be prepared to come or not. Even if there is a network cable in the network center, they may not give it to you, so you need to grind it with them. Finally, wait, usually open the network within 3 days. I don't know much about off-campus networks. You can ask the Unicom business hall in the north of the first restaurant. I also use the intranet, but the intranet is really faster than the intranet.
