I have been having really bad lag as of late and i think its due to my brother getting a gaming PC. Whenever we game together or a lot of devices are being used at the same time, my games get really bad lag. What i have noticed is its not my ping that goes up and down. I play Valorant a lot and i turned on Network RTT jitter on and i've noticed it jump really high. When normal its at a steady 3-5ms, but then it jumps to 20-30ms and sometimes even 100ms and its been as high as 1000ms at times, but rarely. When this happens my whole game will freeze, then all of a sudden im somewhere else in game. Sometimes my character will rubberband. Also at the start or end of a round in Valorant my game will have a big 2-3 second screen freeze a lot of the times. I thought it would be my modem, but i've done some research and there isn't really much i can improve there. I called my ISP and they said there is nothing they can do as i have an up to date modem and my internet speeds are where they should be (400-500mbps).
I've tried new ethernet cables, i've also tried using my brothers PC to see if there is lag there too and there is. Also i've tried downloading games on my PS5 while playing on my PC and there is big spikes when doing so. The only thing i can think of now is buying a gaming router that supports a lot of devices at the same time. My games have become unplayable and i can't think of anything else that can fix this issue. Any suggestions are appreciated!
