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.

PROS

Blazing-fast fiber speeds No data caps Low monthly prices

Cons

Limited availability in rural areas Some connections may be only FTTC Fiber buildout takes time

Quantum Fiber Pricing

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.

Quantum Fiber Reliability and Performance

4.5

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.

Quantum Fiber Equipment, Installation and Bonus Features

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.

Quantum Fiber Experience & Support

4.0

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.

PSA. Do not work with Quantum Fiber it it is an option near you. I currently have CenturyLink ($65 for gigabit). I'm moving now, and I'm being forced to Quantum Fiber (Same company) instead. They jacked up their prices nearly 100% to $55 plus equipment rental for 500 down. It gets worse. I bite the bullet and get it because it's still cheaper than comcast bs. I schedule the install a week out before I'm officially moving (I work from home, internet is vital). 24 hours before the appointment they delay it with no explanation. 3 days later and 3 times contacting them, I have not been given a reschedule or explanation for the delay. This is the scummiest company I've ever encountered and it's not a contest. It has taken me hours to get to the point where one of their reps will actually cancel the account. It's all, 'oh would you like $25 bucks and no information'

If I could give 0 stars I would, they “chose” my backyard to install the main box in, destroyed a main sprinkler line, played the “blame game” about who broke it so nobody ever reimbursed us for fixing it, they are CONSTANTLY demanding access to my backyard to get to the box. My husband let one of their salesman talk him into getting their service (he didn’t realize they are directly tied to Century Link, so the box in the backyard IS there’s), the salesman outright lied to my husband stating that “no they wouldn’t need access to our backyard for installation and that the box isn’t “theirs” when in fact it is and the install went not only to that box, but they had to bury a line across my entire back yard, drill holes in my house, and had no regard to the plants they were stepping all over in my flowerbed while doing the work. I am currently looking for a different provider so I can cancel them and ship their stuff back. The service goes down no less than 3 times a day, the speed is worse than slow, their IT services provide nothing but excuses. We have had them less than a month and I refuse to stay, I guess you get what you pay for, although the price is low the quality is lower than low. If you are considering Quantum Fiber all I can say is RUN don’t walk away from them and go with absolutely any other provider.

Worst service ever. Their installation is a joke. They have no regard for a neighborhood,. They just barge in, take over, ruin yards, install overhead lines with no care, concern or common sense. Based on other reviews of how good their service is, and previous CenturyLink experience, I would never do business with Quantum.

Worse than Comcast and that's hard to do, we do not think there is much (Dumpy Trump) worse than this corp. Everything goes pretty much as expected until your hardware fails. then watch out. They will play every game in the book from no shows, but I knocked but no one answered, its a no show, CYA to get this. 19+ days no internet, finally the dog rats out the clown coming up the drive, and Quantum tell me I have to go to the house where their equipment is, and make an appointment with that homeowner for Quantum to appear for repair, I do not work for them also I have not the slightest idea which house (over there) he talking about, I do not know those folks. Also I do not make up this service persons schedule, I do not know his supervisor WHAT THE HELL????? Why can't he do this, because he F---- lazy and stupid. We quite, took shit off the wall and sent back, never to trust this crap corp again. Now we are back with Comcast and hating every minute of it. A city the size of Denver and the best they can offer are the two crappiest providers on the planet. We have tried there are just no good options. But Quantum is the worst.

When digging for their lines the were incompetent. They hit our underground utility and knocked the power out for several hours. The local power company had to send several trucks out to fix what they broke. When the power came back on one of my major appliances did not come back on. The foreman stated it was their fault and they would replace my appliance. After filing a claim the company decided they will not be responsible for their actions. This is not the first time they did this. It has happened in another local community. They lie and damage property. BEWARE!
