   Two ideas.   
      
   Some routers can steer the signal horizontally; the technology is called    
   "MIMO" (https://en.wikipedia.org/wiki/MIMO). You notice because the    
   router has multiple antenas, maybe four.   
      
   Then you can replace the antena on the router or the remote with a    
   directional WiFi antena. Home made with a box of Pringles. just google    
   for "pringles wifi antenna". I made one and it actually works. But maybe    
   they are sold, too.

   You can calculate it numerically on a computer, by calculating the    
   aproximate integral ;-)
