I have an xbox one and pc that i have moved to my room but the wifi I get in my room is horrendous at best. It is too slow for gaming of any kind and the router isn't that far away from my xbox and pc. I have a belkin n wireless router if that helps any. I have read that powerline adapters use outlets as internet connections are they any good? Running a 50ft ethernet cable to my xbox and pc is out of the question. Are powerline adapters good?
