Quantum Fiber vs. Viasat Internet Providers Compared

Quantum Fiber brings superior internet speeds and reliability at an appealing price.

Quantum Fiber is a fiber-optic network under the parent company Lumen Technologies, which also operates CenturyLink’s DSL-based service. According to the latest data from June 2025, the Federal Communications Commission states that Quantum Fiber is available to just over 2.3% of U.S. households, making it one of the largest fiber-optic networks in the United States [1]. The service operates in 18 states, as well as a number of cities, with the strongest coverage in Arizona, Colorado, Florida, Iowa, Minnesota, Nebraska, Oregon, Utah, and Washington [2]. In May 2025, AT&T announced plans to acquire Quantum Fiber's parent company for nearly $6 billion; the transaction is expected to close in 2026 [3]. AT&T has indicated that no immediate changes are planned and will continue to "prioritize putting customers first" following the acquisition. The sale ultimately resulted in Lumen reporting $915 million in losses for Q2 2025, with Lumen attributing losses to the accounting changes, and "not from money actually spent" [4]. Quantum Fiber delivers symmetrical fiber-optic speeds ranging from 200 Mbps to 8000 Mbps in select markets, with no data caps or contract requirements. The service stands out for its "Price for Life" guarantee, which locks in your monthly rate permanently—a significant advantage in an industry where 63% of customers reported price increases in the past year [5].

Great prices and a Price-for-Life Guarantee.

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.

Fees and the Price-for-Life Guarantee

Quantum Fiber’s "Price for Life" guarantee locks in your plan rate permanently, making it a great deal. Unlike most cable internet providers that raise prices after the promotional period of one or two years, Quantum Fiber maintains your original rate indefinitely. If you sign up for the 200 Mbps plan at $30 per month, that rate remains locked in, even if the same plan later costs new customers $20 more. This guarantee applies specifically to your base service rate. Three potential cost increases are still possible:

1. 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.
2. 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.
3. 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.

Viasat offers simplified pricing with promotional discounts for new customers Viasat restructured its residential pricing in March 2024 to create a more straightforward plan structure. The company now primarily offers two options: Viasat Unleashed and Viasat Essentials. Viasat Unleashed is the company's flagship residential plan, available to approximately 93% of customers. Pricing ranges from $69.99 to $119.99 per month depending on geographic location, with speeds up to 150 Mbps in select markets. This plan operates month-to-month with no contract required, allowing customers to cancel anytime without early termination fees. Unleashed includes unlimited high-speed data, though customers trending toward exceeding 850GB in a 30-day period may experience reduced priority during network congestion, resulting in slower speeds. Viasat Essentials serves as the budget-friendly alternative, offering speeds ranging from 12 to 50 Mbps at a promotional price of $39.99 per month. Unlike Unleashed, Essentials requires a 12-month contract commitment. Customers who cancel early pay a $15 early termination fee for each remaining month on the contract. New customer promotions: Viasat currently (as of December 2025) offers new residential customers $30 per month off their first three months of service, reducing Essentials pricing to as low as $39.99/month initially. Customers must mention this promotional offer when ordering to receive the discount. Data management: While Viasat markets its plans as "unlimited data," there are practical usage considerations. The company defines "typical usage" as trending not to exceed 850GB in any 30-day period. Customers who regularly exceed this threshold may have their connection deprioritized during times of network congestion, similar to how cellular carriers manage heavy data users. However, Viasat does not charge overage fees or completely throttle speeds—deprioritization only occurs when the network experiences congestion. Viasat offers "Free Zone" hours during off-peak times when data usage doesn't count toward monthly totals, allowing customers to schedule large downloads or updates strategically.

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 8000 Mbps plan, for instance, you receive 8000 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.

Satellite technology provides reliable connectivity with inherent speed and latency limitations Viasat delivers internet service via geostationary satellites orbiting approximately 22,000 miles above Earth's equator. This technology ultimately determines both the advantages and limitations of the service. Speed performance: Viasat advertises speeds up to 150 Mbps on its Unleashed plans in select markets, representing a significant improvement over the company's legacy offerings. However, actual speeds vary considerably by location and network conditions. Real-world testing shows Viasat's average download speeds hover around 2.82 Mbps to 5 Mbps in many areas—far below advertised maximums.  Upload speeds remain asymmetrical and significantly slower than downloads across all Viasat plans, typically ranging from 3-5 Mbps. This asymmetry affects activities requiring substantial uploads, such as video conferencing, content creation, cloud backups, and sharing large files. Latency concerns: The most significant technical limitation of geostationary satellite internet is latency—the time delay for data to travel to the satellite and back. Viasat customers typically experience latency between 600-700 milliseconds. By comparison, cable and fiber connections deliver latency of 20-40 milliseconds. This high latency makes real-time applications challenging. Online gaming suffers from noticeable lag that puts satellite users at a disadvantage in competitive play. Video conferencing experiences delays that create awkward pauses in conversation. VoIP phone calls may have echo or timing issues. Websites and applications that require frequent back-and-forth communication feel sluggish compared to wired connections. Weather sensitivity: Satellite internet experiences "rain fade"—temporary signal degradation or complete interruption during heavy rain, snow, or thick cloud cover. This is a major limitation of the technology as precipitation absorbs and scatters the radio frequency signals traveling between the satellite dish and orbiting spacecraft. Service typically returns automatically once weather clears, but customers should expect periodic outages during severe weather events. Reliability advantages: Despite these limitations, satellite internet offers reliability benefits that terrestrial connections cannot match. The service continues functioning during disasters that damage ground-based infrastructure such as hurricanes, floods, or wildfires that destroy cable lines. This makes satellite internet valuable for emergency preparedness and explains why military and maritime operations rely on the technology.

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
• Explaining system features and troubleshooting resources

Professional installation required with lease or purchase equipment options Viasat requires professional installation—customers cannot self-install the satellite dish and modem equipment. A certified technician visits the property to mount the dish, align it precisely with Viasat's satellites, run cabling into the home, and connect the WiFi modem. Installation process: Standard installation typically costs $99.99 as a one-time fee, though Viasat frequently waives this charge during promotional periods. The actual installation cost varies based on results from a soft credit check and the complexity of the installation site. Customers with qualifying credit may receive free installation, while non-standard installations requiring additional labor or materials may incur charges exceeding $100. The installation appointment usually takes several hours. The technician must find an optimal location for the satellite dish that provides unobstructed southern sky view, securely mount the dish, run coaxial cable from the dish to the modem location inside the home, install the modem, and conduct signal testing to ensure proper alignment.  Equipment options: Viasat offers two payment structures for the required satellite dish and modem equipment. Customers can choose either a monthly lease at $15 per month or a one-time lifetime lease payment of $250. The lifetime lease option is basically prepayment for equipment use as long as the customer maintains Viasat service—it is not a purchase, and equipment must still be returned if service is canceled. Mathematically, the lifetime lease becomes cost-effective after approximately 17 months of service ($250 ÷ $15/month = 16.67 months). Customers planning to maintain Viasat service for multiple years save money with the upfront payment, while those uncertain about long-term commitment benefit from the monthly rental's flexibility. Equipment return requirements: When customers cancel Viasat service, they must return all company-owned equipment including the modem. However, the satellite dish itself typically remains mounted on the property—Viasat does not send technicians to remove dishes, and customers who want removal face a fee or must arrange removal themselves.  Failure to return the modem and other returnable equipment results in unreturned equipment fees added to the final bill. Viasat provides instructions and return shipping materials for equipment return. Dish relocation: Customers who move to a new address while maintaining Viasat service can have their dish relocated for a $200 fee. This requires a new technician visit to properly mount and align the dish at the new location. Alternatively, customers can cancel service at one address and establish new service at another address, though this involves separate installation processes and fees. Optional protection plans: Viasat offers EasyCare service plans that cover technical support, service calls, and equipment protection. Multiple EasyCare tiers provide different levels of coverage, with promotional offers including the first three months free for EasyCare and EasyCare+, or reduced rates for EasyCare Premium during the first three months.

Quantum Fiber ratings often skewed by CenturyLink

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, competitive pricing, and the price-for-life guarantee creates genuine value.

Mixed customer experiences reflect satellite internet's technological constraints Viasat does not appear in major national customer satisfaction surveys like J.D. Power, but multiple independent sources provide insight into customer experiences. The ratings paint a picture of divided opinions—satisfaction strongly correlates with customers' expectations and alternative options. The American Customer Satisfaction Index rates Viasat within the "All Others" category at 64 out of 100 [15]. For context, the best internet service providers score 73 out of 100, while the worst score 55 out of 100. Viasat's positioning below the industry average of 70 indicates systemic challenges, though it avoids falling into the bottom tier of ISP performance. What customers praise: Positive reviews consistently highlight several strengths. Customers in rural areas express appreciation for having internet access at all—many note that Viasat represents their only option for broadband speed. Installation technicians receive frequent compliments for professionalism, friendliness, and thoroughness during setup appointments. The service maintains reliability except during severe weather, and customers value 24/7 customer support availability for troubleshooting issues. Some customers report satisfactory speeds for their needs, particularly those with modest usage focused on email, web browsing, and occasional streaming. Long-time subscribers who remember the limitations of dial-up internet or earlier satellite services view Viasat's current speeds as substantial improvements. Common complaints: Negative reviews cluster around predictable issues inherent to satellite technology. Speeds frequently fall far short of advertised maximums, with customers reporting actual performance in the single-digit megabit range despite paying for plans marketed at 100-150 Mbps [16]. High latency makes online gaming frustrating or impossible, creates awkward delays in video calls, and causes general sluggishness when browsing websites. Data usage tracking generates significant frustration. Customers report reaching their soft 850GB cap quickly—sometimes within days—despite limited usage patterns. The company's data usage measurements don't always align with customer understanding of their activities, leading to disputes about whether deprioritization is justified. This issue particularly affects households with multiple users, gaming consoles, or 4K streaming habits. Billing problems appear frequently in customer feedback. Reviewers report being charged after cancellation, experiencing unexpected price increases, receiving conflicting information from different customer service representatives, and struggling to obtain refunds or credits [17]. Multiple customers describe discovering they had been charged for years after supposedly canceling service—a serious red flag regarding the company's billing and cancellation procedures [18]. The equipment return policy creates frustration, particularly the expectation that customers remove roof-mounted satellite dishes themselves or pay additional fees for removal. Elderly customers and those with mobility limitations find this requirement unreasonable and potentially dangerous. Weather interruptions: As expected with satellite technology, heavy rain or snow causes temporary service disruptions. While customers understand this limitation, the practical impact—losing internet during storms when they might most need it for weather updates or emergency communication—generates overall dissatisfaction. Customer service quality: Experiences with Viasat's support team vary widely. Some customers praise quick resolution times and helpful representatives, while others report long hold times, representatives who cannot resolve issues, and internal communication breakdowns where different departments provide conflicting information. Ultimately, customer satisfaction needs to be understood within the context that satellite internet serves areas lacking better alternatives. Customers with access to cable, fiber, or even quality 5G fixed wireless service generally choose those options over satellite. Viasat's customer base includes many people who reluctantly accept satellite's limitations because no other broadband option exists in their area. Compared to its direct satellite competitors, Viasat positions between HughesNet (generally viewed as slower and more restrictive) and Starlink (faster speeds and lower latency, but higher equipment costs). For rural customers evaluating satellite options, Viasat offers a middle ground with better performance than legacy satellite providers, more affordable equipment than Starlink, but technological limitations that prevent it from competing with terrestrial broadband.
