Coverage is specified at up to 2,000 square feet and 25 concurrent devices, which lines up with a typical apartment or small-to-midsize home where phones, TVs, consoles, and smart plugs all compete for airtime.

SpecPicks Verdict

SpecPicks scored NETGEAR Nighthawk Modem Router Combo (CAX30) DOCSIS 3.1 Cable Modem… using a rating × review-volume × price-fit model applied to published specs and reviews across the networking category. NETGEAR's networking lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

Does the CAX30 work with my internet provider?
