Although our fiber service usually means 100% fiber-optic network to your location, in limited circumstances Quantum Fiber may need to deploy alternative technologies coupled with a non-fiber connection from a certain point (usually the curb) to your location in order to provide the advertised download speeds. Customer speed experiences will vary, particularly when accessing the Internet wirelessly from various devices. Download/upload speeds are via a wired connection. Internet speeds are not guaranteed due to conditions outside of network control, including customer location, devices, equipment, and access through a wired or wireless connection; see q.com/legal for more information.
