I use deco x20 for my desktop, and I usually play games like Valorant, and Minecraft.
During early this year, my Valorant ping was about 80 ms, but during end of this year which is now, suddenly ping go straight up to 200 ms 
I really don't know what is the reason, I never touched my network, I used VPN sometimes, but did nothing else could harm the network.
My family use VPN to watch OTT things, and they have no problems with the internet. ONLY ME AND MY COMPUTER HAVE PROBLEM WITH PING WITH VALORANT.
PLS HELP ME WITH THIS. I DONT KNOW WHAT IS THE REASON.
