I concur, stop replying with the FAQ when a bug is being pointed out. It is obnoxious noise and hides true bug data as well as real solutions.
1) power to the MAC spoof. Didn't think of that at first, and can't speak to Windows but anyone with a Mac or Linux laptop can quickly do it straight through sudo ifconfig or homebrew utilities like spoof mac the just wrap a not-complicated process. My phone can randomize MAC for security; I wonder if I can use a utility to do the same.
So far this is the ONLY solution I've tried that not only works but is a breeze to the dispersing ROKU network BUG
2) If your phone can make a mobile hotspot with "Wi-Fi Sharing" then that's the second easiest to just proxy through your phone that is not impacted by the ROKU bug that fails to persist the ROKU hotspot from hotel typical interface long enough to actually authenticate.
DUCTTAPE HACKS ARE NOT REASONS NOT TO FIX A CLEAR ROKU BUG.
