Slow (5 MB/s) Transfer Speeds

I recently purchased a Mybook Live Duo 6 TB drive to store my home media.  I hooked it up to a gigabit wireless ac router but am still getting slow speeds.  I tried connecting via AFP and SMB but it’s still slow.  

How can I get to these mythical 50 MB/s transfers everyone is posting about?  I’m on a 2012 edition Macbook Pro if that makes a difference… thanks!

… don’t use Wireless… 

The Macbook isn’t 802.11ac, is it?
