Pulling a cable from your current network location would obviously be ideal, but not necessarily a requirement if all you need is streaming movies/sports.

How far away is it, and what do you already use for wifi? If you don’t have crazy bandwidth needs, any mediocre wireless mesh should be able to get you streaming.

If you can afford it (~$350+), one with a dedicated backhaul band would be ideal for easy, reliable connectivity.

Do you just need reliable, regular wifi? No special requirements?

I have 2 of the RT-1800S because I wanted a cheap AIMesh network for my house and they’ve been great.

It’s also sometimes called “wireless bridge mode”. What model router do you have? Does it look like this? https://www.amazon.com/dp/B08H8ZLKKK?tag=p00935-20&ascsubtag=01tjJ8n6mlmJ9ardMRzeKVQ

Home networking terminology is obnoxiously convoluted. “AX1800” isn’t really a model, it just indicates the generation (AX = wifi 6) and cumulative bandwidth across all bands. In this case it’s basically saying that you have a 5 Ghz band with a theoretical maximum bandwidth of 1300 Mbps, and a 2.4 Ghz band with a theoretical maximum bandwidth of 480 Mbps which they round up to “1800”
