Not a problem. Stick a network cable in and as and when necessary either use a pair of Homeplug/Powerline adapters or a WiFi adapter.
Homeplugs/Powerline adapters plug into the mains and use the mains wiring to communicate between each other. Or you can get simple WiFi adapters that plug on to the end of the cable to give wireless access to the router.
NOT Homeplugs/powerline adapters. The mains wiring is not designed to be used in this way and to do so causes serious radio interference to your neighbours.
WiFi adapter is OK, and even better is running a CAT5 cable around the room. I can't see what is impractical about that.
