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.

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 They contend that critics’ claims of the firms becoming dominant “gatekeepers” are outdated and that the merger is necessary to keep their services competitive in today’s broadband market.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

Quantum Fiber Pricing

4.5

Competitive, straightforward prices.

Quantum Fiber offers straightforward pricing that includes an autopay discount. Monthly costs are approximately $5 higher if you don't enroll in automatic payments. In most markets, the two primary plans available are the 500 Mbps and 1,000 Mbps (1 Gig) tiers. Multi-gigabit options—up to 2 Gig, up to 3 Gig, and up to 8 Gig plans—are available in select areas. All plans include free equipment rental during an initial period, unlimited data, and no contracts [7].

Value Analysis

When evaluating internet plans, the cost per megabit provides insight into true value. Quantum Fiber's entry-level 500 Mbps plan at $50 per month equates to 10 cents per Mbps—a competitive rate for fiber service. This pricing structure positions Quantum Fiber favorably against cable providers that may advertise lower introductory rates but dramatically increase rates after promotional periods end. Three potential cost increases:

Equipment rental fees: Quantum Fiber provides free equipment during an "initial period." After this period ends, rental fees may apply. You can drop these fees altogether by using your own compatible router.
Installation costs: Professional installation is currently free, though Quantum Fiber states this "could change in the future," and additional products or services might incur extra installation costs.
Taxes and miscellaneous fees: Local and state taxes and regulatory fees may increase over time, beyond Quantum Fiber's control.

No Data Caps or Contracts

All Quantum Fiber plans include unlimited data, allowing unrestricted internet use within the acceptable use policy without overage fees or speed throttling. The absence of contracts means you can cancel or modify service at any time without incurring early termination fees.

COX Pricing

3.0

Be aware of price hikes and data overage for heavy-streaming households

Cox offers a first-tier plan at $55/month for up to 300 Mbps download speeds. That's about $.18 per Mbps, which is on the higher end of the pricing scale. The good news is that Cox's first-tier price is the standard price, so it won’t go up automatically after a promotional period. Unfortunately, the higher speed plans do have steep price hikes after the first year’s promotional rate. And when those price increases kick in, you’ll be paying more per month, on average, than you would for the same speeds through Xfinity or Spectrum. In addition, there’s a monthly rental fee for the Cox modem/router of $13, though you are allowed to buy your own compatible router if you wish. Another big question about Cox pricing will be how much data you use. Cox does have a data cap. The cap is high at 1.25 TB [4], so many households will never exceed it. It's worth noting, though, that the share of U.S. broadband subscribers using at least 1 TB of data per month has risen to nearly 25% in Q4 2024 [5]... up from 14% in 2022 [6]. And if you do exceed your cap, you will face overage charges [7]. In other words, if you are a heavy data user, you may end up with a higher monthly bill. So be aware of these data caps as a factor in your pricing if you live in a household with multiple people who stream 4K or play real-time games online every day. If your internet activities don’t include lots of HD streaming, gaming, or large file uploads, or you only have one or two household members, you are unlikely to exceed your monthly data cap.

Quantum Fiber Reliability and Performance

4.5

Symmetrical upload and download speeds and superior reliability during peak usage times.

Quantum Fiber utilizes fiber-optic technology, which provides two key advantages over cable and DSL: symmetrical upload and download speeds, and superior reliability during peak usage times. Symmetrical speeds mean your upload capacity matches your download speed. On the Mbps plan, for instance, you receive Mbps in both directions. This is valuable for video conferencing, uploading large files, livestreaming, and cloud backups.

Fiber-to-the-Home vs. Fiber-to-the-Curb

In most installations, Quantum Fiber deploys Fiber-to-the-Home (FTTH), where fiber-optic cable runs directly to your residence. This provides the fastest possible speeds with full symmetrical performance. However, in some cases, Quantum Fiber may install Fiber-to-the-Curb (FTTC), where the final connection to your home uses coaxial cable. Even a short coaxial cable segment will reduce upload speeds compared to pure fiber. If you receive an FTTC connection, your download speeds may remain at the advertised levels, but your upload speeds will be slower than the symmetrical speeds typical of FTTH. Before installation, confirm which connection type your location will receive.

Performance Capacity

A gigabit fiber plan from Quantum Fiber supports about 10 devices simultaneously, enabling high-bandwidth activities (such as 4K streaming and online gaming) while maintaining smooth performance. The combination of low latency, high bandwidth, and consistent speeds makes fiber particularly well-suited for households with multiple heavy internet users.

COX Reliability and Performance

4.0

Years of solid operations equip Cox with reliable infrastructure

Cox has a thirty-year record of delivering internet access to customers. This means that when you order internet service, it will work as it should the vast majority of the time. Cox home internet serves metro areas in 18 states. Cox Communications remains a major U.S. broadband provider with around 6–6.5 million residential and commercial customers under its own brand. With its 2025 proposed merger with Charter Communications, the combined company would serve roughly 35.9 million broadband subscribers — making it, if approved, the largest cable/broadband operator in the United States [8]. Cox uses hybrid fiber-coaxial (HFC) technology, like its major competitors Xfinity and Spectrum. Ordinarily, your internet service will be carried by fiber-optic lines along the main arteries until it gets within about a mile of your house. Somewhere near that point, the network will switch to copper coaxial cable. This structure is called Fiber-to-the-Node (FTTN). It is faster than an all-copper network, but not as fast as all-fiber, which is also known as Fiber-to-the-Home (FTTH). Cox does offer a small percentage of all-fiber connections and is building out more, but for the moment, you are most likely to get HFC, i.e., cable internet service [9]. Download speeds with Cox’s cable internet will go as high as 2,000 Mbps in some areas, and upload speeds will top out around 200 Mbps. Though this upload speed is far below the symmetrical high speeds of an all-fiber connection, Cox cable internet still provides plenty of speed for most households. Cox uses data caps of 1.25 TB/month on its plans. This allowance will provide plenty of data for most households. But if you have a large household and you all do unusually heavy streaming or gaming to go over 1 TB, you may incur up to a maximum of $100 in overage charges. You can get Cox plans with unlimited data, but only by paying more each month for an unlimited plan.

Quantum Fiber Equipment, Installation and Bonus Features

4.0

Get free use of a 360 Wi-Fi mesh router or use your own router

Quantum Fiber provides its 360 Wi-Fi equipment at no additional cost during an initial period. This system includes a SmartNID ONT device and up to four mesh Wi-Fi pods. The number of Wi-Fi pods will be determined by your installation technician based on your home's size. Most equipment has Wi-Fi 6 connectivity, but Wi-Fi 7 is available in select areas. The mesh network architecture offers better coverage than traditional single-router setups. This is beneficial for larger homes or properties with thick walls that impede wireless signals. The 360 Wi-Fi system creates whole-home connectivity by placing pods throughout your space, eliminating dead zones and ensuring seamless handoff as you move between areas. This setup supports the high device counts and bandwidth demands typical of modern households.

Professional Installation

Quantum Fiber currently provides free professional installation. The internet provider has noted this "could change in the future," and customers requiring additional products or services may incur extra installation costs. Professional installation ensures proper fiber-optic connection, optimal equipment placement for your home's layout, and immediate resolution of any technical issues. The installation process:

Running fiber-optic cable to your home (FTTH) or to the curb (FTTC)
Installing the SmartNID ONT
Positioning mesh Wi-Fi pods throughout the home
Testing connection speeds and performance

COX Equipment, Installation and Bonus Features

4.0

Cox offers optional self-installation, charges equipment rental fee

When you order Cox internet service, you will be able to select either professional installation or self-installation. Self-installation will save you about $100, as long as you’re willing to deal with instructions for connection and activation. If you want to use a Cox-supplied modem/router, you will get their Panoramic Wi-Fi gateway [10]. Higher-tier plans will receive a Wi-Fi 6 gateway, while the lower tier of plans will have a more typical Wi-Fi 5 compatible device. All customers will pay a $13/month rental fee for the equipment in addition to their monthly plan fee. However, Cox will forego the fee if you use your own compatible modem/router, which may make it cheaper in the long run for you to buy one rather than renting.

Quantum Fiber Experience & Support

4.0

Quantum Fiber satisfaction scores below fiber industry average

According to the 2025 American Customer Satisfaction Index (ACSI) report comparing internet providers, Quantum Fiber scored 71 out of 100 points—a 7% decline from the previous year. This places Quantum Fiber four points below the fiber industry average of 75 [3]. The 2025 ACSI data also indicated that overall fiber provider scores decreased by 1% year-over-year across the industry [8]. The J.D. Power 2024 U.S. Residential Internet Service Provider Satisfaction Study did not differentiate between Quantum Fiber and CenturyLink DSL, instead reporting combined results for Lumen Technologies. In the West, where Quantum Fiber has its strongest presence, Lumen Technologies ranked last with a score of 511 out of 1,000. This combined scoring methodology means CenturyLink's lower-performing DSL service likely impacted the overall rating. If you compare fiber and DSL services within the Lumen portfolio, the ACSI shows Quantum Fiber's fiber service scores 16 points higher than CenturyLink's DSL offerings. This gap showcases that fiber customers report better experiences than DSL subscribers. The 7% satisfaction decline and below-average ACSI score suggest Quantum Fiber has customer experience downfalls regardless of its technical advantages. Issues affecting its customer experience ratings likely include installation delays, equipment problems, billing discrepancies, and customer service responsiveness. Reddit backs this up, with some users frustrated with Quantum Fiber's reliability: "The speed is great, consistent 550mbps up and down, but it is so unreliable" [9]. Other subscribers report a more positive experience, but do note that they are utilizing their own equipment instead of the Quantum Fiber-supplied equipment: "Love [Quantum Fiber], just get your own wifi equipment" [10]. Despite the below-average satisfaction scores, Quantum Fiber remains a strong technical choice where available. The combination of fast symmetrical speeds, unlimited data, no contracts, and competitive pricing creates genuine value.

Cox customer service ranks below average on national surveys

Cox gets a resounding "meh" for customer service on recognized national surveys of customer satisfaction such as the J.D. Power survey [11]. Cox ranks below average in each region where it provides service. In 2025, Cox scored 68 out of 100 on the American Customer Satisfaction Index (ACSI), which places it just below the 70/100 average for non-fiber internet providers [12].

In an industry not known for good customer service, it's hard to split hairs about exactly what the rankings mean. Even some of the best ISPs occasionally get their share of negativity when you look up review compilation maps [13]. But despite TrustPilot's 1-star rating (based on over 1,400 reviews) [14], because J.D. Power and ACSI are widely regarded as among the more objective rating systems, we're going to give Cox 2 stars for customer service.

Pero no se que ha pasado que por dos veces Quantum me ha quitado dinero de mi cuenta , como si yo les debiera algo. Gracias a DIOS he tenido los recibos para las devoluciones. OJOOOO, La vida esta muy dificil y es muy triste que estas cosas sucedan. No se como ellos pueden comprobar que se hizo la devolucion si uno da la informacion pero no lo actualizan en su sistema una ves que reciben de los clientes lo que necesitan. Espero que esto sirva para ayudar a alguien. ha sido en estas dos ocaciones trecientos algo y en la segunda alrededor de $475 Que me han tomado de la cuenta

Absolutely not worth the effort. Customer Service stinks. Field Techs are nice but have their hands tied. Anything you have more than a few years old will not work and the burden is on you to figure that out. All in all. I'll pay XFinity the extra $20 a month. That works.

Salesperson said the installer would be sure we had good coverage in all corners of our house after initial setup. What really happened was the installer recommended aftermarket equipment and when asked for a pod to cover our master bedroom begrudgingly handed it over and then split immediately because it could take up to 2 hours for the pod to connect. The pod came with no instructions but we managed to get it to connect. However, about every 30 minutes we get a flashing green light on the pod and it knocks the internet out to the rest of the house. Would have been great if the installer stuck around to make sure everything was working.

Horrible internet service, even when we are at home, a lot of the time the internet says it’s down, I it’s so overpriced, most of the time I have to use up my hotspot on my telephone just to have decent internet in my home, there is no excuse for this companies all around less than satisfactory service !!!!

Internet buffering happens too much. I'm checking out other companies because Cox Always ups their prices. We are just basic Internet. There are other options for better prices. Cox is the greediest company I've used.
