AT&T vs. Quantum Fiber Internet Providers Compared

Industry-leading fiber internet speeds and strong reliability from AT&T

AT&T Fiber can support all your data-intensive internet activities, now and in the future. AT&T continues to lead the industry with multi-gigabit (5000 Mbps) internet speeds available in select areas and more speed on the way. When you add no contracts, no equipment fees, no data caps, and a reputation for reliable customer service, AT&T is a superior choice for all-fiber internet. In areas where only AT&T copper service is available, customers should also check other options and compare speeds and pricing.

AT&T Fiber internet is affordably priced given its high quality and dependability

AT&T offers reasonable fiber pricing with first-tier fiber internet plans currently starting around $55/month. AT&T won’t always offer you the lowest price for fiber in your area. But AT&T will offer you the low end of industry standard prices. For those prices, you’ll often get higher internet speeds from AT&T than from the competition. You will get good value for the internet speed you’re buying. AT&T Fiber’s advantage is that their fiber connections give you equal download and upload speeds. So, even if AT&T Fiber and a cable provider offer you the same price for a speed they both call “300 Mbps,” you will not be getting the same speeds from fiber and cable providers. All cable internet may have high download speeds, but has much slower upload speeds (usually around 10-20 Mbps). AT&T Fiber will give you the same upload speed as your download speed for your monthly price. Having upload speed equal to your download speed can make a big difference for real-time activities such as video streaming and gaming. Fiber also offers low latency, which you’ll see in a ping test. So overall, you are getting more for your money with a fiber internet plan, even when fiber and cable plans advertise the same prices and download speeds. There’s one drawback to AT&T’s pricing. AT&T’s copper-wired service (DSL/ IPBB) is priced at around the same as its first-tier fiber plan. This price is higher by Mbps given that copper service is much slower and less reliable than fiber. We hope AT&T will consider lowering the price of its copper service to give better value to DSL/IPBB customers.

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.

Decades of growth give AT&T reliable infrastructure and sophisticated operations

As the third-largest ISP in the United States, AT&T has massive corporate size and history on its side. AT&T’s home internet serves over 100 metro areas in 22 states, with over 19 million fiber internet passings [1] [2]. AT&T provides strong infrastructure and tech support. With 99% reliability for your internet connection, AT&T Fiber service is less likely to be disrupted by outages or slowdowns than many other internet providers [3]. AT&T’s reliability rating is higher than some other ISPs because AT&T customers do not have to work with internet data caps. Many internet service providers have soft data caps. When you hit your data allowance for the month, your ISP will throttle your internet. Your internet speed will slow down to the point that only the simplest email tasks will be possible. You won’t be able to do complex web browsing, streaming, or your other usual internet tasks. In other words, your internet will become unreliable when you hit the limits of your data caps. AT&T and other providers with no data caps give you peace of mind because you won’t suddenly lose most of your internet functionality in the third week of the month. Unlimited data is a major bonus for your internet connection’s reliability.

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.

AT&T offers no equipment fees, optional self-installation, extra cybersecurity features

As long as you have AT&T internet service, you will also get to use an internet gateway at no charge [4]. (This gateway is a modem/router combo known as AT&T Smart Wi-Fi.) Your plan may also include a free Wi-Fi extender depending on your terms. If you order AT&T Fiber, technicians will install an ONT (optical network terminal) and a fiber jack or ethernet jack. Professional installation from AT&T will cost you $99 for either copper internet or fiber installation. If you are planning to order copper-based internet (DSL/IPBB) and there is already a dual-port phone jack in your home, AT&T can mail you a self-installation kit at no charge. You can even self-install fiber internet if you are comfortable with a wall installation and following technical instructions. AT&T customers have access to the AT&T ActiveArmor internet security app. The app will block fraud calls and guard risky Wi-Fi connections. For a small extra monthly charge, ActiveArmor offers advanced functions such as Identity Monitoring and Reverse Number Lookup. AT&T also offers a Smart Home Manager app to manage your Wi-Fi and all smart home devices and check for outages.

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.

AT&T Customer Service provides 24/7 tech support and ranks #1

AT&T has a robust customer support framework, including community forums, live chat, and phone assistance. Tech support is available 24/7, which can be a lifesaver if you work or study from home. Billing and account support are available from 7 AM to 9 PM CT Monday through Friday, and 8 AM to 9 PM Saturday. Those Saturday hours are especially valuable if you work Monday to Friday and can’t squeeze in personal business during the week. In 2023, AT&T ranked#1 for Customer Satisfaction in Residential Internet Service (North Central and West regions) with J.D. Power and Associates [5]. AT&T also ranked #2 in the South region.

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.
