AT&T vs. Cox 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.

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

Cox offers a first-tier plan at $50/month for 100 Mbps download speed. That’s about the same as many other providers ask for their first-tier plans. 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, 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 1.2 TB, so many households will never exceed it. But 14% of American households do exceed 1 TB of data usage per month, according to the Benton Institute for Broadband and Society [2]. And if you do exceed your cap, you will face overage charges [3] 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.

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.

Years of solid operations equip Cox with reliable infrastructure

As the fifth-largest ISP in the United States, 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 19 states [1]. 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 [4]. Download speeds with Cox’s cable internet will go as high as 1000 Mbps in some areas, and upload speeds will top out around 100 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 1.2 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 [3]. You can get Cox plans with unlimited data, but only by paying more each month for an unlimited plan.

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.

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. 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.

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.

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 [5]. Cox ranks below average in each region where it provides service. 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 [6]. But because J.D. Power is widely regarded as one of the more objective rating systems, we’re going to give Cox 3 stars for customer service.
