Question High Ping

Sep 14, 2021
I recently got Windows 10 Pro which I use to mainly play video games but for some reason, my ping goes up to 1600 when I use it. My sister had a Chromebook so I used hers to play, ALL FINE NO BUGS, my sister asked if she could use my WIndows 10 i said yes, she used it to play games and was amazed at how the ping went to 80 and lower and never went up. I decided to try the computer again to try it out... Nope same issue ping at 1600 and just stayed there. My sister used it again after me and the same thing happened to her, last time 80 ping and lower. I tried it again same issue 1600 ping, she tried it again 80 ping and so on. What's going on?
