So I have gigabit fiber internet from verizon, which has always been greatly reliable. My router is the ASUS GT-AC5300. I run 2 desktop PC's via wired connection. Recently one of them is receiving perfect download speeds, but the upload speed is ~1mbps. On the other PC both upload and download is perfect. Swapping ports and ethernet cables does not change the results. If i set up the bad upload pc via wifi, i get decent speeds but of course its not the full speed because wifi. I would chalk this up to just being a mobo nic issue, but recently my router does not display any lights at all on the front. some lights come on when i reset it but when the router fully boots all the lights switch off. so I'm wondering if this might be a router issue in the end and its just having some trouble communicating with one of my pc's
