Hello. I'm trying to figure out what is the best and most powerful long range adapter to use under Win 8.1 to get connected to wi-fi spots in hotels (when the spots are usually quite far from the buildings). I'm interested in both connecting to open spots as well as getting connected to a password protected ones. Googled about Alfa Network products and got recommendation for a AWUS036NH with a higher gain antennas, like the one here: Login or Signup to view links / downloads Is this a true best option in terms of range and stability for going under Win 8.1? Are there any reasonable alternatives? Thank you.
