I've uninstalled LAN drivers and let windows automatically install them, i've also manually installed them myself and the problem is still here. I also thought maybe it was my firewall so i deleted norton anti virus completely, i can confirm it isn't my anti virus. I thought maybe it's my cable, i can confirm it's not my cable, i've tried multiple and i've tried the same cable on another computer and the problem doesn't persist. Now here's what's even weirder, if i start my download on epic launcher and it's around 750kb/s and doesn't go any higher if i open steam and start a download my steam download speed will immediately go to around 35mb/s and my download speed on epic games launcher will magically start to go higher and higher, almost as if epic games launcher or rockstar launcher don't have enough priority to start downloading at max speeds. Also if i connect to the Wifi using the computer with the problem my download speeds immediately pick up and are above 20mb/s on epic launcher and Rockstar launcher. No, it's not because if i got to my second computer and try and download anything the speeds are fine. Not even 1mb/s, now you might be thinking well maybe it's just their servers. Now here's the problem, if i open Rockstar game launcher or Epic games launcher and try and download anything from there, i get below 800kb/s. My download speeds on steam are correct and it usually goes to around 40mb/s in some cases, everythings fine and dandy. Right so basically my internet speed 350mb download which translates to about 35mb/s on steam if i'm downloading a game. I'm at my wits end, i don't want to format my system but it seems like i might have to as a last resort.
