Moving my Hub to another room.

I have recently moved into a new property and have had a gig1 box setup to a pre existing port in the living room. The house has now been decorated and the rooms allocated. How do i go about having the router changed into to the office so i can run ethernet. and be closer (wirelessly to other devices) 

Also receiving regular ping spikes which instantly drop but cause interruptions in online games. My hardware is all good my side and happens even with ethernet.
