No its not about 15ms or 20 we are having ping spikes all the time and alot of the time my ping goes over 900 and I can't play its making the game unplayable
I tried the cable it is much better now sadly this is a short term solution I'll see what I can do
I'm shocked! I've just 1,092 on my ping, this has never happened to me and the modem is a few meters away from the PC. Here you go: https://pilo.ovh/album/cmd.Nz1Q.
