Think line of sight more than raw distance. Behind a metal TV frame or inside a cabinet the dock blocks a lot of signal, even if you are only eight feet away. Stand the dock so the front faces the room, pull it to the edge of the shelf, and keep any drives or hubs a foot away.
For a guaranteed fix flip on Pro Controller Wired Communication and run a longer USB C cable to the couch. That bypasses the noisy air entirely.
