Sichuan University has three campuses (Jiang 'an, Wangjiang and Huaxi), and all campus networks are free. I haven't been to Huaxi, so I don't know much about it. I guess it's similar to Jiang 'an Wangjiang. Don't worry about the network cable, make sure everyone has an interface, and the school allows external networks and broadband (usually telecommunications). The following details, Jiang 'an's campus network speed is not good, look at Youku Duka, but mainstream websites can still be opened. Online games can only be played in the education network area (for example, the education network area in Fang Hao and the QQ game education network area are not allowed). Thunder sees the type of resources. If there are suitable resources, it will be very fast (1~2M per second), and some will not be downloaded. Jiang 'an broadband does not need extra cables, just use the interface of the dormitory and the account password for opening an account. I feel that the campus network in Wangjiang is faster than that in Jiang 'an. You can quickly watch Youku, and if you download it, you can also watch the resources. You can go to 3M quickly. Usually you can download movies on Thunder, and the speed is not bad. Wangjiang's broadband needs another line. The interface of the dormitory can only be connected to the campus network, and you can't log in directly with a broadband account.
