Quantum Fiber vs. Frontier Internet Providers Compared

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

Quantum Fiber is a new, all-fiber brand owned by parent company Lumen Technologies. Lumen is the seventh-largest ISP in the U.S., based on its combined internet service of both all-fiber internet and DSL. In total, Lumen serves about 3 million customers [1]. Quantum Fiber is the all-fiber brand of Lumen. A second DSL-based brand also owned by Lumen is known as CenturyLink. We will review CenturyLink’s DSL service separately, as the two brands are very different in what they offer customers. Quantum Fiber is a very strong choice for internet service that earns good customer satisfaction ratings. If you sign up for Quantum Fiber, you’re going to get lightning-fast speeds and reliable service. Quantum Fiber offers clear, low pricing for gigabit fiber speeds that run up to 8000 Mbps. Fiber speeds will provide you with an internet connection that can handle any use you want from a home internet connection, including heavy streaming and gaming.

Great prices for Quantum Fiber plans up to 960 Mbps

Your prices will be good for Quantum Fiber. The first-tier price for all-fiber service will be $50/month for 500 Mbps. With any of the Quantum Fiber plans, you will get the use of a 360 Wi-Fi router for free. Quantum Fiber has no data caps and no required contracts. That means you won’t run into unexpected data overage charges or early termination fees. We like this simple, affordable pricing for fast fiber speeds. It's one of the best deals you’ll find on fiber internet.

Frontier will give you a good deal on fiber, but DSL varies widely

Frontier is the 8th-largest internet service provider in the United States, with 2.8 million broadband subscribers [1]. The company has a total of 9.9 million copper passings and 6.8 million fiber passings. At the end of 2023, over 70% of their customers were fiber internet customers [2]. Frontier’s main distinction among fiber internet providers is that you will get faster speeds compared to the competition. For example, Frontier’s first-tier fiber plan costs about $29.99 per month at present, like many of its rivals. But that Frontier plan will give you 100 Mbps download and upload speeds, where many other fiber providers tend to start at 200 Mbps and 300 Mbps. With modem-router rental included and no data caps, Frontier Fiber offers the kind of simple, clear pricing that earns high ratings from us. The only drawback is that Frontier Internet (the name for their DSL plans) does not provide the same kind of bargain. Frontier pricing is just average for DSL in the industry. Plus, the DSL speed you will be able to get at your address will vary depending on infrastructure. (DSL usually ranges from 3-50 Mbps download and 1-3 Mbps upload.) Average DSL pricing in the industry is not a great deal for customers compared to cable and fiber pricing. That’s why Frontier and many other providers are moving away from copper-based service in favor of fiber.

All-fiber internet from Quantum: the latest and greatest technology

Quantum Fiber uses the newest internet technology available. Their fiber-optic lines send data using light signals instead of electricity, and that’s why fiber is so much faster than any other kind of internet technology. An all-fiber connection will give you symmetrical speeds and enough bandwidth to handle any internet activities you choose. If you get a gigabit fiber plan, you can have up to 10 devices doing heavy streaming or real-time games online, and you will still have smooth performance. In some cases, though, Quantum Fiber advises that it may need to run Fiber-to-the-Curb (FTTC), with the last few feet of line to your house connected with coaxial cable. This is important, because even those few feet of coaxial cable will slow your upload speeds. Most of the time, that will not be the case, and you will get the all-fiber connection known as Fiber-to-the-Home (FTTH). But it is important to understand the difference in performance just in case you’re in that small minority that will get an FTTC fiber connection. Even an FTTC connection may still be the fastest internet in your area, though, and a Fiber-to-the-Home connection will definitely be your fastest choice.

Frontier Fiber offers speed and reliability, but their DSL lags behind

Just like pricing, performance for Frontier plans is heavily split depending on whether you get fiber or DSL. With Frontier Fiber, you can get multi-gigabit speeds up to 7000 Mbps. That’s right up there with the top few providers in the fiber internet business. And pricing for the 2 Gig and 5 Gig plans is cheaper than comparable offerings from other ISPs. These multi-gigabit speeds will be more than sufficient for very large households with many devices all streaming or gaming simultaneously. Even 500 Mbps is still a lot of speed and will be more than capable of supporting a five- or six-person home and all the devices in it. DSL performance will be unpredictable, but the only constant is that it will not deliver fiber-like performance. If you’re lucky, you’ll get a speed above 25 Mbps download. With that speed, you’ll be able to do most standard internet activities such as streaming and browsing, though you’ll have to watch how many devices are online at once. But if you get a speed that’s 10 Mbps or lower, you may find your service glitching or freezing during heavy-data tasks.

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

If you order a fiber plan from Quantum Fiber, both your equipment and installation fee will be included free of extra charge. Keep in mind that equipment fees and prices do change with various promotions, so make sure you check with your customer support rep on current fees when you call. If you use the free router included with your Quantum Fiber plan, you will get their 360 Wi-Fi system. 360 Wi-Fi is a mesh network, which is much more sophisticated than a single modem/router [2]. You will be able to set up extra Wi-Fi Pods to ensure seamless coverage of your entire space, which is especially helpful if you live in a large home or one with thick walls. You will also have the option to use your own router. The only drawback is that Quantum Fiber tech support cannot give service or information for your personal router the way they can support their own equipment.

Installation fees waived with one year of service

Frontier provides your basic modem/router at no charge when you get fiber internet or DSL. For both technology types, standard installation fee is $100, but the fee is waived as long as you keep your service for at least 12 months. So, you basically get free installation unless you cancel before the year is over, in which case you'll pay a pro-rated fee.

Quantum Fiber earns high customer satisfaction ratings

Because the split in branding between Quantum Fiber and CenturyLink DSL is still very recent, we have to interpret customer satisfaction rankings that were previously based on the name “CenturyLink” for both brands. Customer satisfaction is much higher for Quantum Fiber than for the DSL provided by CenturyLink. The American Customer Satisfaction Index shows that split in results by dividing “CenturyLink” specifically into fiber and DSL. Fiber (aka, Quantum Fiber) ranks 16 points higher than the DSL service [3]. For Quantum Fiber, these customer satisfaction rankings tell the story clearly. You are likely to have a great internet experience with Quantum Fiber. To avoid confusion, be aware that there is still a certain amount of online cross-marketing between the two companies. Pay attention to the speeds available, whether your internet source labels it “Quantum Fiber” or “CenturyLink.” If the speed is above 200 Mbps, it is a Quantum Fiber product. If the speed is 100 Mbps or below, it is CenturyLink DSL. Overall, we highly recommend Quantum Fiber for its top-of-the-line speeds and reliability, great pricing, and good customer satisfaction ratings.

Frontier Fiber shows strong performance in customer satisfaction

Frontier's reviews have improved greatly with increased fiber service, as is reflected in higher rankings in the J.D. Power Residential Internet Service Provider Satisfaction study [3]. Frontier's sharp rise in the rankings is a promising sign that if you get Frontier Fiber, you will be happy with your choice. In addition, Frontier outranks even strong fiber competitors in the well-regarded national survey known as Net Promoter Score [4].
