In 5000 sq ft home we use Netgear Orbi WiFi 6 mesh router and companion unit to get coverage to lanai, pool area, much of the yard, garages and even much of our driveway. Comcast/Xfinity (Spectrum is not an option for us). I did not try with just the router alone, but it might work. Best Buy sells and supports, so it would be easy to buy, try and return if necessary. I buy Best Buy for audio video equipment and appliances, and I use Geek Squad when I don't feel like being solely responsible for my own installations. I pay an annual fee and receive discounts and preferred on site and telephone service that more than pays for itself, at least for me.
I ran cat. 7 and cat. 6 to SMART TVs. I use Tivo and Apple TV. I use small network switches to connect TVs and other devices to internet. I do this to eliminate and maintain a fast, reliable connection without lag and without mismatch of audio and video.
