Instead, it sticks to its network protocols and changed the pings time. This way, network protocols and ping time do not line up together which could solve the issue. 

Method #4: Use an Ethernet Cable

Due to the tightened network latency, users might face this issue. When connected to Wi-Fi modem, the servers do not respond appropriately and may cause it to slow down.
