Quantum Fiber Staff rating

4.3

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

COX Staff rating

3.5

Cox offers gigabit download speeds, but at higher prices than competitors

Cox offers fast, reliable cable internet service and in a few select areas, all-fiber internet. But mostly, when you order Cox service, you’re going to get very fast cable internet up to about 2 Gigs. In fact, 99% of Cox’s customer base gets gigabit download speeds [1]. The lowest-priced plan will remain constant in price after the promotional period and has no monthly contract. All other plans go up by steep price increases of $25-$50 after the promotional rate ends. Overall, you are likely to pay more with Cox than with its cable or fiber competitors. That said, Cox may still be your best option if you happen to live in an area with no stronger fiber or cable internet providers who will give you more speed for your dollar. Beyond its service offerings and pricing structure, Cox has also been at the center of several major industry developments. Recently, Cox has been in the news for jointly defending its proposed $34.5 billion merger with Charter before the FCC, arguing that the two companies do not compete directly and are struggling with declining subscriber numbers [2]. They contend that critics’ claims of the firms becoming dominant “gatekeepers” are outdated and that the merger is necessary to keep their services competitive in today’s broadband market.

Additionally, the Supreme Court has recently signaled sympathy toward internet providers in a high-stakes copyright dispute with major record labels, raising concerns that a ruling for the music industry could force ISPs to police users or disconnect entire households, campuses, or towns [3]. The justices appeared wary of the sweeping consequences proposed by the labels, even as they pressed Cox Communications on the limits of its legal theory.

The developments ultimately highlight how Cox’s role in broadband extends beyond day-to-day internet service and into broader regulatory and industry-wide challenges.

PROS

Wide availability of gigabit download speeds Data caps are high at 1.2 TB, decreasing likelihood of overages Reliability of cable connection

Cons

Big price hikes after promotional rates Data caps may result in overage charges Below-average customer satisfaction ratings
