I play games
Valorant
CSGO
COD
Fortnite
and in all these games me and my brother have packet loss issues, ofc me and him are connect with cable both of us connected to different modems around the house 1 in my room that only Im connected to and the same for him. I tried checking my cable maybe problem with the wires that create packet loss after switching the cable nothing changed. i checked for updates on my modem, pc everything and it didnt change, my friend who lives close by dosent have the same problems so i dont believe its the games servers in my area problem. Please help what can I do ?
