I use a single ethernet cable (cat5e) to switch between a PC and a PS4. In the task manager under network I can see that it recognizes the 40Mbps I'm supposed to be receiving but my ACTUAL download speed is hard capped at 4Mbps. This problem doesn't occur with the PlayStation. I updated the network adapter's driver as well. What could be causing such a discrepancy? Any help would be greatly appreciated!
