Please try this fix. I'm not sure if this will work for everyone, but let me know if it does. I haven't done enough testing, but I'm confident to say I have fixed the "issue" on my PC. I would get kicked non-stop since the game's release to the point where it was unplayable. I have tried every solution in the book to fix the problem (even factory resetting my PC). Every time I got kicked for inactivity, I would look at the event viewer log to see an "ethernet disconnected" warning. So, what fixed my issue was to replace every flat CAT7 ethernet cable I was using with round gold rated inland CAT6 cables. I went from disconnecting multiple times a day to not at all now.
TLDR; Replaced flat CAT7 ethernet cables with round CAT6 ethernet cables.
