I was having similar problems (although at an obviously different scale since I have 75mbps cable) in my living room, since my router is in the office. My ps4, Xbox, phones, etc in the living room would pull maybe 1-2mbps on speed tests. I thought I needed a new router. Instead, I picked up this guy: http://www.netgear.com/home/products/networking/wifi-range-extenders/EX7000.aspx
Loving it so far. Hard wired the game devices to the extender and get 60+ on speed tests regularly now. Phones, iPads, and computers all have better service as well. My guess is that I had a middling router that didn't pair well with weak device antennas, but my middling router pairs well with this, and my devices connect a lot better to this either wired or wirelessly for better overall service.
Just thought I'd share my experience in case it gives you something else to try.
