Method 1: Connect the lan port of the router to the interface on the wall with a network cable, and this is the AP. Enter the router (refer to Method 2) and turn off the DHCP service, as if you have to log in to a dial-up interface every time before surfing the Internet, and then you can do it.

Method 2: Connect the network cable to the WAN port, enter the gateway ip in the browser address bar, and enter the account number and password in the pop-up box, which can be found at the bottom of the router. Select dynamic ip in Internet settings to intervene, save and restart the route. It seems that we have to dial the login interface first.

Difference:

In fact, 1 means that you regard the route as a switch and expand three interfaces similar to a wall. The advantage is that you can play against other dormitories online, and other dormitories should also be visited by 1.

2. Build a wireless local area network and connect it to the campus network with a router. The advantage is more security, but you can only play in one dormitory.
