Several computers * * * use the Internet. Because the router is too bad, others download and watch movies, which will drag the router to death or occupy the network speed, leading to network instability. It would be better to restart the router. The long-term solution is to suggest a better router that can limit the speed, and then set the allocated network speed, so that each other will not be affected.
