Hello, I have an Ethernet connection to my router, which connects to a root outside of my house. With that being said, I have a fairly stable connection to the internet, with my ping hovering around 30-50ms while connected to European servers (I am from Poland). I noticed that while playing shooters, I get random packet losses of up to 10%, and while playing TFT during combat rounds, I sometimes get up to 2-4k ping. I'd like to ask for advice on what could be causing this situation and what I can do to fix/reduce the problem. I see that there is a certain pattern to this situation, and I believe someone with more expertise on networking could help me with their intel. Thank you for the read and advice.
