Straight to the point is, my ethernet will stop working while doing heavy load like downloading stuff and play games even though doing normal stuff is mostly fine, after i change the Speed & Duplex thing in the ethernet properties to anything but auto negotiation, it work perfectly without any problem, it has been like this for a while now and i cant fix it, dowloading is slow and so is everything, does anyone have an idea how to fix this? Im using windows 11 25H2 26200.8246. Sorry my english is bad

edit: i also have an extend ethernet cable

what i have to do to play normally
