Lightning-fast, reliable internet at an excellent price

Xfinity is a fantastic provider overall. It offers fast speeds, reliable service, and reasonable prices. Some plans still require contracts, and others still have data limits. Watch out for Xfinity’s hidden fees and spotty customer service record, but it may not be as bad as it once was.

What we like

  • Consistently fast speeds
  • Wide availability
  • Excellent pricing
What we dislike

  • Data caps on some plans
  • Some billing complaints

Fast, reliable fiber for larger households and power users

Ziply offers impressively fast, reliable internet for medium to large households, power users, and businesses. Ziply's internet speeds go up to 50 gigs, which is way more than most internet providers! Ziply offers super low-cost introductory pricing for 12 months, and they include professional installation for free. Overall, Ziply is a trusted, transparent internet service provider in the Northwestern US.

What we like

  • Low introductory prices
  • Fast internet
  • Free professional install
What we dislike

  • Pricing stipulations
  • Price increase after 12 months

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.

Fast internet speeds at a great price

Xfinity is generally a very good value, especially at the middle and lower tiers. In fact, it offers some of the best budget plans of any of the major internet service providers. Eligible households may qualify for high-speed internet as low as $9.95 a month with unlimited data and equipment.

Depending on your area, you can get a 50 Mbps Internet Essentials plan for less than $20 per month and a 400 Mbps plan for $50 per month. Those plans have a data cap of 1.2 terabytes which is a high data cap. Data caps are common among cable internet service providers (ISPs). Removing it costs an extra $30. But overall, this pricing is an excellent deal for the speeds you're getting.

The 400 Mbps plan, which is about right for an average family that's online a lot, is also a great price. It rings in at about 36% of the national benchmark in its range. (1) That means you're paying just $0.18 per megabit, with plenty of megabits to go around.

Faster internet plans are available from Xfinity. Some areas can get speeds up to 2 Gbps, and others can get plans as fast as 6 Gbps. For reference, 6 Mbps is ridiculously fast, and it also comes at a higher price. Most households don’t need 6 Gbps internet speeds unless they’re streaming a ton of 4K content or have several people gaming online at the same time. These fast internet plans do come with unlimited data, though, so it might still be worth it for some households.

Low-cost internet plans

Ziply offers fast fiber internet at great prices. You get an exceptionally low introductory price for 12 months. Plus, you get professional installation at no charge, which is about a $90 value.

Ziply's pricing and promotions depends on your location and service area. You get very low, promotional pricing for the first 12 months, and then prices increase after the introductory period. You can ask what the price increase may be after your introductory period, but Ziply says this estimate is subject to change.

Ziply's low promotional pricing for the first 12 months is contingent upon enrolling in autopay and paperless billing. Here's an estimate of Ziply's promotional pricing and increases in select areas:

  • Fiber 100/100: $20 a month for 12 months, then $45 a month
  • Fiber 300/300: $30 a month for 12 months, then $65 a month
  • Fiber Gig: $50 a month for 12 months, then $85 a month
  • Fiber 2 Gigs: $60 a month for 12 months, then $95 a month

Ziply's slowest internet plans (50 Mbps and 200 Mbps) are the best value, priced at 25% and 33% of the national benchmark, respectively for their introductory prices. (1) Its 1 gig plan is relatively more expensive, but its introductory price still comes in under 45% of the national benchmark for similar plans.

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.

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.

Available speeds vary by location. Call 1-844-448-0617 to speak with a Cox rep or

Some of the best internet reliability

Xfinity internet performance is excellent. Its speeds are fast and reliable. In fact, in many markets, it has one of the fastest internet speeds around. Xfinity's internet service is reliable and consistent. If outages occur, Xfinity is responsive and generally restores service within hours. Xfinity internet is also highly rated for speed (2), and research from the US Federal Communication Commission (FCC) scored it among the top for reliability (3).

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.

Equipment and installation

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 options can vary widely depending on

Equipment and installation

DIY or professional install and Wi-Fi equipment

Xfinity internet offers the choice of professional and self-installation. The professional option is often more affordable than competitors, at $100. It's required if you haven't had Xfinity service at the address for more than 12 months. The self-install kit is free, but you may pay for shipping and handling. If you have trouble installing yourself, you can contact customer service for help, but beware that you may face long hold times.

As for equipment, the Xfinity xFi gateway is fairly typical (and costs a fairly typical $14 per month). You can add a Wi-Fi extender (and unlimited data) if you bump up to xFi Complete for about $15 per month for the first two years (and $25 per month starting in year 3). This is a bit steep for just the extender—you can grab an excellent Wi-Fi extender for right around $50. However, using Xfinity's equipment gives you unlimited data, and you qualify for a free upgrade after three years.

If you use your own equipment, unlimited data costs an extra $30 per month for lower tier plans, but is included for plans of at least 1 Gbps.

Free professional installation

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.

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 in our own experience with Cox, we've had solid customer service interactions. 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.

Rapidly improving customer service scores

The Xfinity internet customer experience is a mixed bag. On the one hand, you have reliable service, with the option for unlimited data if you want it. This makes for a great day-to-day experience with Xfinity.

On the other hand, Xfinity internet has a spotty customer service track record. It ranks above average on customer surveys (4). While customer service seems to be above average, not everyone has a great experience, and we've seen some complaints about billing issues and miscommunication between the company and their technicians.

If you need to connect with the company, we recommend using its customer service portal and downloading the Xfinity app first before trying to reach reps by phone.

No contracts but early cancellation charges

Ziply has a good reputation for customer service. They offer free professional internet installation and no contracts, which are nice perks. Compared to competitors, Ziply prides itself on transparency.

Ziply provides excellent support. We love that Ziply provides professional installation for free, but we wish they offered a self-setup option, too. But it's nice that it's installed for you and it's one less thing you have to do yourself. Ziply has some great self-help content on its website for troubleshooting or changing out your router later if you'd like.

Ziply is really transparent about a lot of things related to their internet service. Ziply is clear that their promotional pricing is just for 12 months and it increases after that period. They're also transparent with the fact that you need to enroll in autopay and paperless billing to get promotional pricing.

One thing that's not clear in Ziply's language is that you may have to pay early termination charges if you cancel before 12 months of service. This can be a bit confusing because Ziply says it doesn't have contracts. 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, people are overall happy with service, and most negative reviews call out the same kinds of issues other providers get: billing disputes. (4)
