My Plex server and my main PC each have their own gigabit connection to the router, I know for sure that each connection speed is gigabit. However, when I transfer files between them I only get up to 5MB/s (megabytes per second).
I should mention that each ethernet connection is done via powerline adapter. I have four of these in the house that all work together. But I don't think this is what is causing the issue however I could be wrong.
Please help me!
