i've been begging for over 5 years.
My PS4 is in the basement and my bedroom on the second floor of the house. I play games in bed with no issues. It didn't work properly until I changed the ad-hoc type though...something I had read on here I believe but it worked like a charm. Its pretty awesome. I suck at BF4 on my Vita due to the sensitivity of the sticks, but I'm still playing Beef in my bed and that's dope.
Try changing the ad-hoc type. That worked for me, it plays very well. No noticeable lag for me.
Is this on the PS4 or Vita? What adhoc type are you using?
