Ethernet over power line adaptor


No Cat 5 or 6 wired upstairs in listening room in new house.  I had Cat 5 in previous.  How shall I best run Naim UnitiServe?  I’m told Netgear and others have a device.  Recommendations please for best product and application.  Thanks in advance.

I used a Netgear Poweline 1200 from an outlet next to my router in the basement to an outlet on the 2nd floor next to my Node2.  After installing signal went from very week to very strong with no cutouts.  
thanks marco1 that device will work for my issues as well, didn't even know they were available great...
