I tried a bunch of different ethernet cables, and also purchased a new one today which doesn't work on the pc. I currently have wifi so I know the internet is good.I recently upgraded from a zotac 1070 to a geforce rtx 3070 vision OC as well as an upgraded power supply. All of the sudden my ethernet connection can no longer be established. I also have no wifi on this pc and am currently using a laptop. I have tried a lot of things I have seen on the internet including resetting the network. I think it is a problem with my drivers I really am not 100%. Does anyone have a fix?
