I did the dirty work under the house and ran the ethernet cable. The end at the closet was on the ground, it had not been run upstairs. I pushed the cable through the hole in the floor into the closet and added an RJ45 connector inside the closet to this cable. While under the house I also found the fan was turned off so I turned it on so now both fans run periodically. The display runs now using the wire under the house. This is good news. Dinner tonight was cheese and spinach ravioli in Marinara from Trader Joe.
