Me and my friend struggle with high ping spikes in game. When one of us connect to the other computer average ping 100 - 120 ms, but most of the time it is jumping between 1k - 10k ms.
What did we found: if one of us connect ISP cable directly into computer ping become around 10 ms, but in case if both of us use router we had that bad ping that I mentioned, both of us use wired connection from router to pc
Tried to change router but issue didn’t gone
Ping ours IP’s via CMD shows ping around 1 ms, we are users of the same ISP.
Could somebody tell, please, what could be a problem and how we can fix that?
