Low starting prices and reliable internet speeds

Cox provides a great customer experience and reliable speeds, but you’ll spend more for higher-speed plans, extra data, and add-ons.

What we like

  • Plan variety and options
  • Great customer experience
  • Generous, unthrottled data cap
What we dislike

  • Expensive plans
  • Steep data overages
  • So-so availability

Fast, reliable fiber for larger households and power users

Ziply offers great pricing for medium-to-large households and absurdly fast internet for power users. This provider has a few quirks, like hidden contracts and no self-setup, but if those don’t bother you, Ziply is a solid internet service provider in the Northwestern US.

What we like

  • Low prices
  • Fast internet
What we dislike

  • Hidden contracts with promotional pricing
  • No self-setup
Cox
Value
3.0
Good budget plans, but you’ll pay high prices for top speeds

Cox plans range from around $0.60/Mbps for low-speed plans to around $0.10/Mbps for the fastest plan, which is more expensive than other cable internet providers. The good news? Cox has more lower-speed plan options, so if your internet budget tops out at $50 a month, Cox might be your new best friend. At speeds of 200 Mbps and above, however, Cox loses the price war.

What you get for the money is pretty good. All plans have a 1.25 TB data cap (unless you pay an extra $50 per month for unlimited), but that’s more than most people need. And unlike providers where unlimited comes standard, Cox won’t throttle your speed if you get a little data-hungry. Just beware of overage charges (which can really add up) if you go over the limit.

Low-cost internet plans—unless you want the fastest speeds possible

Overall, Ziply offers fast fiber internet at great prices. Its slowest plans (50 Mbps and 200 Mbps) are the best value, priced at 25% and 33% of the national benchmark, respectively. (1) Its 1 gig plan is relatively more expensive, but it still comes in under 45% of the national benchmark for similar plans. After introductory pricing ends, your monthly bill will increase by about $20 per month, but you’ll still pay less than average. Plus, you’ll get unlimited data.

If you want the absolute fastest internet possible, Ziply also offers 2- and 5-gig plans, but these come with much higher price tags. A 2-gig plan is nearly double the cost of a 1-gig plan (no bulk discount here), and a 5-gig plan is nearly 4 times the cost! (2) And there’s no introductory pricing for these blazing-fast plans. You’ll also need to spring for your own router (the Ziply one doesn’t support these speeds). 1 gig should be more than enough speed to cover the vast majority of households, so we don’t recommend springing for these plans unless you’re sure you need them.

Cox
Performance

Speeds are very reliable, but expect minor slowdowns at peak times

Generally, Cox delivers the speeds it says it does, sometimes even a bit higher—though the speed you experience also depends on lots of factors, such as the equipment you’re using and your distance from the router.

Cox specializes in cable internet, which is faster than DSL and satellite, but slower and less reliable than fiber. It’s also typically cheaper and more reliable than wireless internet. The US Federal Communication Commission, in fact, says actual speeds from Cox are faster than advertised and nearly identical to competitor Optimum. Those speeds are stable, too. The report found slowdowns less than 5% of the time. (1) However, cable internet is known to be slower during peak usage times because you and your neighbors are all using the same street lines.

5.0
Fast, reliable fiber in most areas

Ziply has a fiber optic network, which is the most reliable kind of infrastructure out there. Fiber also allows for faster speeds than any other kind of internet, including upload speeds that are just as fast as download speeds (AKA symmetrical speed). Unfortunately, Ziply’s 1-gig plan isn’t symmetrical, serving up only 35 Mbps for upload, and that’s a shame. Still, most families will find a symmetrical 200 Mbps connection plenty fast, while high-powered users can opt for a 2- or 5-gig symmetrical plan (though it’ll cost you big).

Other than that, Ziply performs pretty well. It typically uses only 40% of its infrastructure capacity (3), which means you’re less likely to see slowdowns during peak hours. However, Ziply has legacy DSL infrastructure in some rural areas and tends to perform slower than other DSL providers.

Cox
Equipment and installation
3.0
Rent a Gateway or bring your own networking equipment

Cox’s Panoramic Wi-Fi Gateway ($13/month to rent) is a modem and router in one, and you can purchase (but not rent) additional Wi-Fi pods ($129.99 each) that plug into a regular power outlet to reduce dead spots in your home. Because these pods can be used only with Cox, they're only an ideal solution if you plan to be with Cox for several years. The good news is Cox is also compatible with tons of other modems and routers, so you could save a few bucks while using your own gear.

With Cox, a self-installation kit is free. But if getting set up on your own makes you sweat, a Cox professional can install it for $100... but that installation cost goes up if your home isn’t already wired up and ready to go. They’ll ensure cabling makes it from the street into your home, but you might need to hire a contractor or handyman to run wires to a specific room.

Equipment and installation
4.0
Equipment and installation costs mostly balance each other out

Ziply’s equipment costs can add up. Its router/modem combo is a reasonable $10 per month, but its Whole Home Wi-Fi costs $20 per month. Sometimes, Ziply runs promotions that include Wi-Fi, so keep an eye out for those. Ziply’s Wi-Fi is Wi-Fi 6 technology, which is the best technology available. You can stream up to 12 devices at once (Wi-Fi 5 allows only up to 5). However, Ziply’s router isn’t compatible with its 2- and 5- gig plans. If you want one of these plans, you must BYO router, and not all routers are compatible, so be careful here.

Professional installation is free, which is great because Ziply doesn’t have a self-install option. Technicians will run cables from the street to your home, wire up your house, and set up your Whole Home Wi-Fi. The downside is technicians likely won’t get all this done in a single visit, so it might take a few weeks to get you up and running.

Cox
Customer experience
3.5
Decent customer service, and you can pay for extra tech help

Reviews for internet service providers are notoriously low in general, but Cox does pretty well according to our real customer reviews. The American Customer Satisfaction Index (ASCI) ranks Cox ninth in customer satisfaction among internet service providers—the same as Frontier. (2) That's lower than average, but not by much.

We think Cox’s 30-day, no hassle money-back guarantee is solid. And we like its service. If you opt for self-installation, you can still get plenty of help online or by phone if needed. But if you use your own gear or technology isn’t your thing, $10/month will get you extra help, day or night, for things like malware removal, software installation and reconfiguration, and general troubleshooting.

Could be more customer-friendly with more self-help options and better transparency

We love that Ziply provides professional installation for free, but we’re bummed that it doesn’t even offer a self-setup option. Ziply has some great self-help content on its website for troubleshooting or changing out your router later—you just can’t use it to get started. Forcing you to use professional installation also means it takes longer to get started, and that’s tough if you’ve just moved to the area. If you’re not moving, it still means you’ll have to juggle your old service with Ziply installation times to avoid a gap in internet service.

We’re also not a fan of Ziply’s hidden contracts. It advertises no-contract plans, but if you read the fine print, you’ll pay early termination charges if you try to leave before your promotional plan ends. All that said, Ziply’s customer service is decent, and most negative reviews call out the same kinds of issues other providers get: billing disputes. (4)

My review for Cox is a pleasant experience overall. Sometimes the reliability and speed is not consistent. This makes me long for a more reliable service.

Cox has been very reliable over the past 18 months. The technician who came to my house was friendly and good at his job. I would love if their prices were a little lower, especially for cable.

Price was fine, but they are adding charges all the time. They need to make sure the customer feels taken care of. The last time we were on the phone, they made it seem like it was our fault when their lines were faulty. And they didn't offer a break or a credit for the downtime.
