eero (Amazon) - eero Pro 7

If you're on internet only you can just buy an Eero kit and use that instead of the FiOS router/extender, then you're not paying any rental fee and you'll likely get better wifi performance. I would recommend the Eero 7 two pack, or the Eero Pro 6E two pack, both should be $300 or less and cover a 3000 square foot house unless its got concrete or brick interior walls. For the highest speeds and lowest latency you're gonna need to be wired, though at only 300mbps you can still get decent speeds wirelessly you don't need the most expensive/sophisticated hardware, though it'll still suffer compared to wired performance. https://imgur.com/j1jt7Qo I've managed 2gbps over wifi, but it requires specific hardware and network settings to achieve those speeds.
