Ping is normal, but there is packet loss, which leads to this. The network is a telecom broadband installed by the landlord of a single apartment, which is used by three people ~

First, packet loss in general telecommunication networks is not serious, and playing games below 5% will not be affected at all, and it will not cause jams.

Second: determine what the broadband bandwidth is. If a broadband bandwidth is not enough, it will be divided into three rooms, which will definitely lead to a jam.

Third: first make clear the first and second questions, and then discuss with the landlord whether to solve them and how to solve them. If you can't solve it, set up your own broadband.

If you have any other questions to add, you can continue to ask me.
