First time trying ethernet weird expierence

[The Select Few]

For context... I am a high-level rocket league and Fortnite player where every micro second and micro movement matters drastically in mechanics aspect of the game. I've always noticed something was wrong with my game in rocket league, I remember searching on YouTube "why does my car turn so slow" when I was 12-14 years old on my Xbox one, I am now 20.

I purchased a PC in 2023 thinking it would fix input issues since I'm getting higher fps and such. First game I tried was RL and it felt way worse than on my Xbox one, I mean the smoothness was better, but when I made contact with the ball, my car would react in horrid ways, impossible to do chain resets/ multiple flip resets in a row. My car feels like its moving through water

Fast forward to 2025 I buy a TP LINK powerline ethernet to see if getting my internet from a different source other than Wi-Fi would help at all, Plug the powerline adapter into the wall near my pc, than hooked up the ethernet cable from the powerline ethernet to my PC.

The heaviness was completely gone, my car was turning 100% output left to right almost instantly and my car was sticking to the ball off resets not bouncing absurdly, and in Fortnite I was able to get 15-20 quad edits in a row when usually I can barely get 2. BUT I was rubberbanding horribly, I have never ever gotten real lag where it teleports me or rubberbands me ever before, it was very consistent and happened every half a second or something in a pattern which I thought was very weird, but my games were responding flawlessly, and physics were actually physicalizing lol. EVERYTHING WAS PERFECT EXCEPT FOR RUBBERBANDING

I was happy that I got to experience 0 input latency and 0 desync only dealing with rubberbanding. so, I purchased a 150 ft ethernet to go from my living room to my room from the real router. Lo and behold everything is happening again, ball bouncing very weird off car, can't hit consistent triple resets in rl, can't do quad edits consistently anymore in Fortnite.


Does anyone have an explanation for this? It was a night and day difference in desync and latency except I was rubberbanding in a pattern which made it pretty much unplayable,

when I fixed input inconsistency and desynchronization issue another arose. The only thing that makes sense is that something correlates between electricity and networking.

Did you try switching back to the powerline adapter to see if it resolved the issue again?

I’ve bought and tried powerline adapter so you wouldn’t have to. I have no rubber banding everything is smooth like with cable , just 2-3ms jitter. Same shit feeling as with cable or wifi.
