Quantum Fiber brings superior internet speeds and reliability at an appealing price.
Quantum Fiber is a fiber-optic internet service originally developed by Lumen Technologies. On February 2, 2026, AT&T acquired Lumen’s Mass Markets fiber-to-the-home business (including Quantum Fiber) in an all-cash deal valued at $5.75 billion. The acquisition included consumer fiber operations in 11 states, adding more than 1 million fiber customers and over 4 million enabled fiber locations to AT&T’s network. Lumen retained its enterprise network infrastructure and copper-based services, while AT&T integrated the acquired fiber assets into its expanding fiber broadband portfolio.PROS
Symmetrical fiber speeds No data caps or contracts Competitive cost-per-megabit value
Cons
Limited availability Some connections may be only FTTC Multi-gig plans not available in all service areas
Xfinity Staff rating
Xfinity pairs a fiber-powered network with a rare 5-year price guarantee Xfinity is Comcast’s residential internet service and one of the country's largest providers, with 28.65 million residential broadband customers across 41 states. It runs a fiber-powered, hybrid fiber-coaxial (HFC) network (fiber deep into the neighborhood, then a coaxial line for the last stretch to your home), and in independent Opensignal testing from 2026 it ranked first nationally for consistent quality, download speed, and video experience. Every plan includes unlimited data and equipment, and at checkout you can lock your rate with a 1-year or 5-year price guarantee. Download speeds reach up to 2000 Mbps, with symmetrical multi-gig available in select markets. All-fiber providers still hold an edge for the heaviest upload work, but for most households, Xfinity’s mix of speed, unlimited data, and price stability is tough to beat. One of the most widely available providers in the U.S. Xfinity scores a 4.5/5 stars for availability because it is available in 41 states and Washington, D.C., spanning more than 11,000 cities. If your area has cable infrastructure, there’s a strong chance Xfinity reaches your address, and that footprint is one of its biggest advantages. It also means Xfinity is frequently the only high-speed wired option in a given area, which has real implications for pricing and service quality.
PROS
Available in 41 states 5 year price guarantee Unlimited data Gigabit download speeds
Cons
Coaxial last mile trails all-fiber for the heaviest uploads Shared neighborhood capacity can slow peak-hour speeds for some users Autopay and paperless billing required to hold the guaranteed rate
