For example, the dormitory uses a router with Qos(ip bandwidth limitation) function and logs in the interface of the router. Select the connection mode-speed limit setting mode. For example, the bandwidth is 2M, 200~300k downstream and 80- 120k upstream. If you want to increase the bandwidth, you can allocate more points. Suppose the ip addresses of your two computers are192.168.10 (your computer) and 192. 1 1 (other computers). The setting method is as follows: enter the initial IP192.168.10 and terminate the IP:192.168./kloc-0. Set the download rate of 2M bandwidth to 250 KB/s .. from192.168.1.1to IP:192.168./kloc-0.
