Optimum vs. Cox Internet Providers Compared

Optimum features good speeds but poor customer satisfaction scores

Optimum is a major national cable internet provider. Most of Optimum’s 4.3 million subscribers receive cable internet service. But the ISP is also adding some all-fiber connections in select markets. Optimum is the internet brand name of Altice USA, which rolled the company formerly called Suddenlink into the Optimum brand in 2022 [1]. Altice/Optimum is the 6th-largest ISP in the nation [2]. Optimum seems to check off all the right boxes for many of its offerings. You will have no data caps and no required contracts with Optimum internet plans. You will also get free equipment rental included with your monthly plan price. And Optimum’s prices are good (at least while the promotions last). So why are Optimum’s national customer satisfaction scores so low? We’ll check into that as we give you an overview of what to expect from an Optimum internet connection.

Good initial prices followed by price hikes

Cable internet is the chief type of connection that Optimum provides its customers. Because of improvements to cable internet technology, you can get gigabit download speeds from many cable internet companies like Optimum. You just won’t get the same upload speeds from cable as you will from an all-fiber connection [3]. Whether you get the usual cable service or all-fiber, you will get good prices from Optimum, and those prices will be locked for 2 years. Here’s an example. You’ll pay $40/month for Optimum’s first tier plan, which is up to 300. That is a good price for these speeds. The catch is that after those two years, standard prices will take effect, which will spike your bill higher. That may be why Optimum is seeing year-over-year declines in its cable customers [4]. The price hikes may be pushing people to other options at the end of their two-year promotion.

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.

Cable and fiber both provide fast download speeds, but cable's upload speeds are slower

With hybrid fiber-coaxial (HFC) technology, Optimum gives its cable customers gigabit download speeds but much slower upload speeds. That’s typical for cable internet service. Optimum is comparable to other major cable internet providers such as Spectrum and Xfinity, offering upload speeds at a maximum of around 35-50 Mbps. Optimum differs from the cable internet competition because it is also launching into the all-fiber internet market. Optimum’s current fiber internet customer base is small but has doubled in the last couple of years from around 100,000 to over 200,000 subscribers [4]. By 2025, Optimum plans to create over 6.5 million fiber passings [5]. Fiber internet’s most striking advantage over cable internet is that fiber offers symmetrical upload and download speeds. This is a game-changer for online gaming, videoconferencing, and large homes with multiple devices. When Altice merged Suddenlink under the Optimum brand, the company had two distinct “footprints” left from where the old Optimum and Suddenlink coverage had existed. Suddenlink’s coverage area had been primarily in the South and West. Optimum was strong in the Northeast, and particularly in the tri-state area of New York, New Jersey, and Connecticut. Now, the fiber buildout is fastest in that tristate area [1]. Your chances of getting fiber internet from Optimum in the next year or two will be better if you live in the tri-state area.

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.

No equipment rental fees, free installation with Optimum plans

Optimum will provide your modem/router as part of your monthly plan fee, with no extra rental charge. If you have a compatible cable plan, you may even get a Wi-Fi 6 router, which will give you higher speeds for multiple devices than Wi-Fi 5. Fiber internet plans from Optimum will often include the Wi-Fi 6 gateway as well. If you would rather use your own modem and router, Optimum will allow it. Just be sure to check for compatibility with their specs. Standard installation is free with Optimum plans.

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.

Optimum customer satisfaction: the big question mark

With so many seemingly good points to its service and pricing, why has Optimum’s customer satisfaction scored significantly below average according to J.D. Power? [6] A random sampling of online user reviews seems to indicate two major complaints. The first is outages and failure of technical response. The second is a more general dissatisfaction with the phone system, being transferred around to different departments, and getting contradictory responses from different phone reps when trying to solve billing issues. Because this is a fairly even distribution of complaints, it’s likely that Optimum is just not quick enough in responding to customer concerns, whether they be technical or billing-related. We can’t know the reason for this dysfunction. Often, these kinds of responsiveness issues happen when companies are understaffed or have high staff turnover in their customer service. But until Optimum gets better ratings, we have to give them only 3 stars for customer satisfaction.  

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.
