Need wifi home network without internet access. [View all]

Moving to the boonies and internet service is basically non existent. Only internet I will have is smartphone which is ok for now.

I need to connect a printer and a wireless thermostat. Running windows 10 on a dell gaming desktop.

How do I do this?

Also if there is any experience with wireless thermostats I'd welcome it. Have a 1200 sq ft two story and will live upstairs so want thermostat up there instead in the old 'living room' downstairs.

Tried to find local advice but to on avail. No wonder retail is dying, no knowledge, no help just take the card and run.

eta I don't care about setting the thermostat with my phone or puter, just want to control temp from living area not from the vacant first floor.
