Just a question: you wouldn't happen to have coaxial cable in the house, right? If so, you could use an adapter to run ethernet over it: https://www.amazon.com/

Just a question: you wouldn't happen to have coaxial cable in the house, right? If so, you could use an adapter to run ethernet over it: https://www.amazon.com/dp/B008C1JC4O/ https://www.amazon.com/dp/B008C1JC4O/ I agree with the other poster, if you want reliability then there is no substitute for ethernet. Anything else will simply have lower reliability. That said, I'd personally try HomePlug (ethernet over powerline) solution first. I was not able to get that stable and have tried two generations of the technology. If it works -- fine, if not, I'd try mesh products like Eero next. They're owned by Amazon though, which I personally wouldn't like. I did hear some good reviews on the ATP.fm podcast, who usually are quite critical.
