Quantum Fiber 360 WiFi uses the most advanced WiFi 7 technology to deliver faster speeds and stronger signal coverage compared to older WiFi 5 or 6 equipment.

Not quite, but they do work together. Fiber internet is the connection that comes straight to your home or small business through fiber-optic lines. Wi-Fi is how you wirelessly connect your smart devices to the fiber internet inside your home. Together, Quantum Fiber Internet and 360 WiFi bring you an ultra-fast, reliable internet experience.
Nope. We don't do annual contracts, so there are no long-term commitments or early termination fees. Just fast, reliable internet on your terms, paid month to month.
That depends on your household. If it’s just you streaming and browsing, lower speeds may work. If you've got a house full of gamers, binge-watchers, and remote workers, and everything from smartphones to a smart thermostat, you may need a faster speed (like up to 940 Mbps).
Easy! Just run a quick speed test here. You can do this on WiFi, but for the most accurate results, plug your computer directly into your modem or router with an Ethernet cord.
