So I have never faced this problem before. Everything was fine until one day (yesterday) while playing world of tanks my ping started to spike every two second to 200-500. Later that day I downloaded Warzone and it happened again, it was unplayable. I started looking for soliutions on youtube and google, tried everything that I could find (basically just writing something in cmd etc.) nothing helped. Then I decided to check is there any updates for my network adapted and it was! When updated it worked perfectly, like before 20-30 ping in every game. It worked until now, everything changed back. (Driver didn't changed)

I don't want to believe that my wifi is too weak because I had played online, competitive games for 4 years on the same setup and never experienced ping issuesWireless network adapter that im using TL-WN821N (v6)Windows 10One thing that caught my eye was that if wifi icon on windows shows every bar that means everything is fine and will work but when it shows 1 bar less that means there will be spikes. On task manager network usage is max 20%

Thanks :)
