I have done "Ping 188.8.131.52 -t" command and I see my ping fluctuating pretty badly. In-games such as LoL, CS:GO, Dirty Bomb, Dota 2 I get over 300ms. I don't know the reason this is happening. I reinstalled windows recently due to a bug so I have next to nothing on my computer but a few steam games and ccleaner/malwarebytes. I have consulted my ISP and I am in tier 3 support which they are configuring settings(they say). This has only just recently happened(Friday), could of my ISPs network team configured something wrong on Friday? Also my download speed normally is around 40mbps and my upload around 19mbps but this weekend my download has been 0.4-5mbps and my upload has been 0.3-1.6mbps. with my ping being 40-60ping on the speedtest. Any help is appreciated.
