Thanks for your quick response. I did the changes you suggested. This is a plot from last night when the game was working OK. I have done a lot of test but cant figure out what is going on. Sometimes the last hop is in 230ms but the game is unplayable, and in some occasions is near 280ms but the game works fine at 230ms (in game ping metter). In every situation I have checked the IP that the game is using. Im doing a plot right now when the game is not working well to send it later. I think is a problem with my ISP and the international data transfer, because Youtube at this moment is really slow but then later like 2 AM local time starts to work better. I have tried 3 different routers too (Zyxel, Huawei and TP-Link) with just one PC trough ethernet (no other devices connected).
