Thanks very much for the comments/info.

The TV is only 30 feet away without any walls but I think the wifi in the TV is not very good - 2012 might have been the first year of "smart" TV's. I may soon get a better TV but still I think having the ethernet patch cable feed will always be better and maybe faster. I can run the ethernet patch cable, not easy but doable.

I didn't know I could get a Roku with a RJ45 input. Do I need a hub so that the Roku and TV can be connected to the Ethernet right near the TV?

I looked at EERO but it will not support my current HP printer. You can buy printers that can be connected to the EERO network but the instructions seem daunting. Then I would have two wireless networks in the house. I looked at ethernet over power but the plugs are on different panels, not even going to the same panel so I don't think that will work.

My best option is to convert my jerry-rigged wire across the room to putting it through the wall and outside the house and then inside the attic and over to the wireless router wall.
