I am desperate with this issue because it's been bothering me for 7 months now. I called many times my ISP and every time they say that everything is ok. But as soon as i start any kind of Online Game, in that moment my ping jumpst like on a trampoline, i get normal 10 to 25 ping and then BOOM 400 and back to 20 ; This keeps happening all the time regardless the day time. I tried to change the antenna cable of my ISP, nothing changed. I changed router, still the same issue. The weird thing is that when doing a speed test with high pings in game, the actual ping is low, like i had 300 ping in a game and 20 on the speed test. While doing a CMD test though i saw great spikes in response, like it almost hit 1000 PING but only for a few seconds after the game has been closed, after that on idle is perfectly normal. This also gives me another issue, packet loss, that regardless what i do, keeps coming. Either on up od dl while i use my internet connection. Even after a MOBO change and system format the problem still persists and i can't find a fix for it.
