Insane Packet Loss

I've played on the beta and the game ran fine. Perfectly even. At launch of the full game, the game also ran perfectly. Until a week ago where I randomly started getting the package loss icon on my screen. Constant glitching through the map, teleporting around, lower fire rate than what the gun is supposed to have, bullets not registering, gliding forwards, side ways, diagonally, up and down when I stand still after running or walking.

This is just not playable anymore. Absolutely bummed out about it because I really started loving the game once again. But now I simply can't play because of the package loss.

Infantry is a no-go. Operating tanks? Doable, but even my tank is glitching everywhere. Operating jets? Seems to work other than a glitching jet/screen. Helicopter is okay, but when I change camera to 1st person my whole helicopter just glitches around.

I've reset my router, unplugged all Ethernet cables, bought new ones and rewired those towards the router and pc. Drivers are all up to date. I also tried different things like flushing dns in cmds, going in properties on bf6.exe. But nothing that I found as of now has worked yet.

I've refrained from playing this game for 3 days now, because I genuinely can't play anymore because of it.
