Roamio wireless help

I have a base model Roamio, and a mini, connected by an Ethernet cable to the the next room , through the wall.



I'm moving, and the new place tv spot will be like 30 feet away, and no clean way to run a cord.



The Roamio is easy enough to put next to my router, but I would like to connect the Mini wireless to the Roamio.



Can I use the wireless n adapter, what will I need to make it work, Thanks
