So I have a wired connection. Recently I started experiencing packet loss in online gaming in which the game would freeze and the character would teleport. The net graph shows loss of data. I ran a ping test to the game server in the background just to cross confirm. It shows request timed out whenever I lag. When I run the ping test to my ISPs local node it doesn't show loss normally. But if I run some large downloads or play game while doing it then the loss bumps up to 2-3%. All the tests were run with a test to the router simultaneously and the loss to router was 0% always. My ISP claimed it was the server problem and dismissed it. Is it my ISP's fault. What do you think should I do to solve the problem?
