sorry if this is the wrong place to post this.
Recently i switched to steam os on my pc, installed battle net and everything went smoothly. I played in beta and i dont have issue but when i play on live my ping would shoot to 1000 to 4000. and it only smooth on the first 10 minutes or so. I dont know what else i should do so any help is appreciated.
things i tried
restarting.
Im using starlink so i tried to relocate the dish.
turning off firewall in my asus modem
turning off firewall in my pc
turning on and off qos
turning on and off ipv6
changing poton
I tried several ping checker and in my browser everything seem normal


I had a lag spike situation on a steamos machine playing a game called shape of dreams when using wifi but not ethernet, and it wanted a network card driver update. Kind of a shot in the dark but you might try it.
I’m reading that there’s a network stats API that addons can use https://warcraft.wiki.gg/wiki/API:GetNetStats
Maybe there’s a network performance monitor addon you could find, but I don’t have suggestions there.
