Excellent fast fiber internet service at low prices

If you can get fiber internet from Frontier, it's fast, affordable and reliable. If you only have DSL from Frontier available in your area, the internet will be slower and more expensive for what you get. The good news is that Frontier is constantly expanding its 100% fiber network across the United States.

What we like

  • Well-priced fiber plans
  • Fast speeds
  • No data caps
What we dislike

  • Limited fiber availability
  • Some customer complaints

Fast speeds and reasonable pricing

If you can get fiber internet from Optimum , you'll get great all-around service with fast speeds and reasonable pricing. If you can get only cable internet, you'll get slower max speeds and may see different pricing. Both options are decent, but watch out for third-year price hikes and potential customer service hassles.

What we like

  • Affordable prices
  • No data caps or contracts
  • Both cable and fiber offerings
What we dislike

  • Very limited availability
  • Average customer service
  • No true budget plan

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.

Frontier offers excellent value on its fiber plans

Frontier offers exceptional fiber internet at a low price. Prices vary depending on your service area and eligibility, and starting prices are an amazing deal. Here are Frontier's current Fiber offerings, which includes a discounted price for 12 months when you sign up for autopay:

  • Fiber 200: 200 Mbps for $29.99/mo
  • Fiber 500: 500 Mbps for $44.99/mo
  • Fiber 1 Gig: 1,000 Mbps for $64.99/mo
  • Fiber 2 Gig: 2,000 Mbps for $99.99/mo
  • Fiber 5 Gig: 5,000 Mbps for $129.99/mo

Frontier fiber service is generally an excellent value. You can get 500 Mbps for around $45 per month or 1 gig for around $65, both of which are excellent prices well below the national benchmark for similar plans. (1) If you get 2 gigs for around $100 a month or 5 gigs at about $130, you'll enjoy excellent reliability and super fast speeds.

Some Frontier internet plans come with extras for free, depending on eligibility. If you sign up for the 5 gigs, free tech support is included. These are all great prices for the value you're getting. Some Frontier plans may come with expert installation or a Wi-Fi router included at no charge.

If you sign up for Frontier's DSL plan, it's quite a bit slower than fiber internet, but it's a great choice if you're in a rural area. Frontier's DSL plan is around $50 per month for up to 115 Mbps, but the actual speed varies heavily with the specific area you’re in. The good is that Frontier guarantees its DSL pricing for two years and doesn't require you to sign a contract. That's definitely a rare perk in the internet world!

Frontier offers fiber in a good portion of its coverage area, but if you're off the beaten path, DSL is a great solution and Frontier offers fast DSL speeds, depending on where you live. (4)

A lot of internet for a little money

Optimum offers a lot for the money. Both fiber and cable internet plans start at 300–500 Mbps, with a very competitive price that beats the entry-level plan for competitor Spectrum and is way less than national benchmarks (1). That's plenty fast for most online gaming and work from home needs, but you can pay for even higher speeds if you have a big household.

Compared to the competition, the two lower-tier plans almost always offer more speed for the money. And while you can technically find cheaper gig plans, Optimum still tends to be the most affordable in its markets.

If you qualify only for cable internet with Optimum, your speeds will be slower but you'll pay about the same every month. Prices are higher than other cable internet providers at these speeds, but you may not have a choice. Most areas that don't have fiber internet won't have multiple cable internet options.

We love the low starting prices, 2-year price lock, and 60-day money back guarantee, but you can expect prices to jump $35–$85 in your third year of service.

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

Outstanding fiber performance and standard DSL service

Frontier's fiber internet performance is excellent, with speeds up to 5,000 Mbps and no data caps to limit you. In fact, Frontier's fiber plans are some of the fastest (2). Frontier's fiber internet has the fastest ping of any provider, according and a study by the FCC (3), and it's neck and neck with the competition in terms of speed and reliability. These fiber plans also offer symmetrical speeds, which means the upload speed is equal to the download speed. This is crucial if you upload or share a lot of large files, do video calls, or play games online in real-time.

Where fiber isn't available, Frontier offers pretty fast DSL internet. Frontier offers upload speeds up to 115 Mbps, but the speed you get relies heavily on where you live. For many households, 115 Mbps is plenty, especially if you don't stream HD video or have multiple people online at the same time trying to do video calls or gaming online.

Available speeds vary by location. Call 1-833-970-0804 to speak with a Frontier rep or

Optimum internet is both fast and reliable—what’s not to love?

Optimum performance is solid. With speeds up to 2 Gbps (12000 Mbps) in some states, there’s enough bandwidth available for even the heaviest of streaming households. Even the lowest-tier plans offer plenty of speed for most use cases. The cable service is generally very reliable, as well, and usually even faster than advertised, with better latency than any cable competitor. (2)

Additionally, Optimum offers fiber internet service in some of its coverage areas, which offers extra reliability and symmetrical speeds. That’s an excellent feature for content creators and anyone who shares a lot of large media files. Recently, it started offering home internet plans up to 5 Gbps, a speed that’s nearly impossible to beat.

Equipment and installation
3.5
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

No charges for equipment—seriously

Frontier offers fantastic value when it comes to equipment and installation. If you have Frontier's DSL internet, the equipment itself is fairly standard. It's free, which is nice, but you might still want to use your own gear if you need more control over which devices on your network get bandwidth priority. DSL installation typically costs $85, and there's no self-install option. Depending on your plan and service area, you may qualify for free installation.

If you have fiber internet from Frontier, you're in luck! You get free rental of an eero 6 on the Fiber 1 Gig plan or an eero6E mesh Wi-Fi system, on the Fiber 2 Gig plan. If you have the 5 Gig plan, you'll get the TP-Link AXE300 6E with an optional TP-Link RE815XE Wi-Fi extender for an extra $10 per month. You could still technically use your own gear, but it's hard to do any better than the latest and greatest from eero and TP-Link.

If you're eligible, you may be able to get a Frontier self-install kit—otherwise, a professional will come to your house to install the internet for you. If you need a pro to come out, you may be charged $50 on your first bill. In some areas, professional installation is included free, if you're eligible.

Frontier makes cancellations easy. Cancellation is also free, but some customers are charged a $20 restocking fee for rented fiber gear and a $50 restocking fee on DSL gear.

Free pro and self-installs, or you can pay for extra device setup

Optimum offers a fairly standard wireless gateway with both its fiber and cable plans. The combined modem and router are usually free, but may cost you $10 per month on top of your bill in some areas. You can also add Wi-Fi extenders for $3 each per month, which is handy for larger homes and offices (and not a bad price, either).

If you want to use your own equipment instead of Optimum's free gear, you may run into difficulties. Optimum doesn't list compatible equipment and requires at least some third-party modems to be purchased from its stores.

With Optimum installation, you can do it yourself or have a pro help, and either way is free. If you order online, you can opt for a free standard professional installation or pay $59 for a premium installation, where the tech will configure Wi-Fi on up to six devices for you. While other providers may offer to set up your main device during installation, we haven’t seen such an extensive guarantee elsewhere. This could be a selling point for less tech-savvy customers.

Customer experience

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.

Can't sign up for service online

The Frontier customer experience is a mixed bag. The service itself is fairly reliable—especially the fiber. The DSL service is relatively stable, but more prone to slowdowns during heavy traffic times (which is typical with all DSL internet).

Frontier has received low scores in customer satisfaction from organizations like the American Customer Satisfaction Index (ACSI). (3) The provider ranked second-worst in overall satisfaction in the most recent surveys, falling below average. The complaints we’ve seen point generally to a broad pattern of poor customer service, so if that’s a key factor in your choice of provider, you might want to steer clear until Frontier can sort out its issues.

If you order Frontier internet, the only way to order internet service is to call in. It works okay for most people, but some folks love the convenience of handling everything without having to deal with phone trees, wait on hold, or talk to a live human. At least the hold music is nice, though, and you can enter info via text message!

Great internet brought down by customer service complaints

Optimum provides a good customer experience overall. Both types—cable and fiber—are fast and stable, and we haven’t seen any major complaints about reliability. We think the day-to-day experience with Optimum is fine.

However, the company’s customer service is less than stellar, with one of the lowest ratings of all providers, according to the American Customer Satisfaction Index (ACSI) (3). Most of the complaints we’ve seen involve a poor experience dealing with customer service reps. Optimum does offer solid online support options, so you may be able to get around these issues. And, of course, not everyone has a poor experience.
