Astound Broadband offers very inexpensive internet at fast speeds

Top-notch customer service and shockingly low intro pricing make switching to one of Astound’s brands (Wave, RCN, Grande, or enTouch) an easy choice. Astound Broadband offers internet speeds varying from 300 Mbps to 1,500 Mbps. You can lock in a very low introductory rate for one to three years, starting at around $20 a month! Astound Broadband often offers extra perks when you sign up, like an Amazon gift card, a month of free service, and 50% off installation.

What we like

  • Award-winning service and speed
  • Low introductory prices
  • No contract required
What we dislike

  • Price increase after intro period
Savings tip: Astound Broadband often has sign-up promotions for first-time customers. Call to ask a rep about current deals and discounts.

Great fiber service, if you can get it

CenturyLink offers excellent fiber internet, but it’s available only in limited markets. If you can't get fiber, you may be able to get a DSL connection but you'll pay nearly as much.

What we like

  • Unlimited data across all plans
  • Fast fiber connections in select markets
  • No contracts
What we dislike

  • Limited fiber availability
  • Much slower DSL internet speeds
  • Below-average customer service

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

Lock-in a low price for 1–3 years

Astound Broadband offers very inexpensive DSL, cable, and fiber internet plans with at least three plan options and no data caps in most areas. Nearly all plans are priced under $50 for the first year.

For many Astound Broadband internet plans, you can get speeds up to 300 Mbps for as low as $20 a month with a three-year price lock. For speeds up to 1,000 Mbps, you may be eligible to get a deal for $20 a month for six months, and then $55 a month with a three-year price lock. Even after price increases, that's a deal. National benchmarks for similar plans are in the $130 range, so you’ll be getting a great deal. (1)

You can make the most of Astound Broadband's internet offers in a few ways. One, sign up for Astound internet online. Astound Broadband offers some deals exclusively online. Two, sign up for autopay and e-billing with Astound. When you use an automatic bank account, you'll save the most. You'll save a little less when you use an automated credit or debit card. Three, look at current deals Astound is offering. You can often find offers that include an Amazon gift card, one month of free internet, or 50% off installation, depending on your eligibility.

Great fiber value meets high-cost, low-performance DSL plans

CenturyLink offers two types of plans, depending on your location. The more common option is DSL, which is relatively slow and offers inconsistent speeds. The other option is fiber, which is extremely fast and reliable.

Generally speaking, the DSL options are not a great value. The price is reasonable, but the speeds mean you’re likely to get more for your money elsewhere (this is true for many DSL providers). The fiber plans are a much better value—they offer much more speed for the money than CenturyLink’s DSL plans and are competitive with other providers’ fiber offerings. In fact, CenturyLink's 940 Mbps plan costs a little more than half of the national benchmark for similar plans. (1) We highly recommend CenturyLink fiber if you have it available.

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.

Award-winning speed

Astound Broadband is very fast. That said, as with most ISPs, you may not experience the speeds advertised for your plan because speeds fluctuate based on numerous conditions.

With Astound, the speed on your plan is the “average” that customers see, so your speeds will vary depending on the gear you’re using, time of day, how many devices are using your Wi-Fi, and more. If you see persistent speed issues, Astound encourages you to call customer service to get help figuring out the issue.

Available speeds vary by location. Call 1-844-443-5172 to speak with a Astound Broadband rep or

Performance
4.5
Performance is excellent for areas with fiber access

There’s a performance divide based on the type of service available. The CenturyLink DSL plans can range from 15 to 100 Mbps, which is a wide range. Additionally, 15 Mbps just isn’t great these days. It doesn’t even reach broadband speeds (25 Mbps or more). That said, you shouldn’t have to worry about getting the advertised speed—whatever plan you sign up for, you seem to get what you pay for with CenturyLink.

On the other hand, the fiber plans offer Gigabit speeds (up to 940 Mbps), which is excellent. Additionally, fiber internet offers synchronous download speeds and upload speeds, meaning you can game, video chat, or upload large files just as fast as you binge Netflix. Fiber also tends to be inherently reliable because of the way the technology works—the light signals in fiber optic cables can carry more information over longer distances than coaxial cables. We have no complaints about performance on these plans.

Available speeds vary by location. Call 1-833-804-2792 to speak with a CenturyLink 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
DIY or professional installation

You can rent a modem and one of two Wi-Fi routers from Astound, bringing your total monthly equipment costs between $17 and $27. For most people, the Whole Home Wi-Fi router option will be the right choice. It includes an eero mesh router and an extender, and you can add more extenders to ensure coverage throughout your entire home. This is a reliable Wi-Fi router that supports fast internet speeds, up to 1,500 Mbps!

You can get fancier equipment yourself, if you are a power internet user. Gamers and other heavy streamers can consider the Nighthawk Pro gaming router to reduce lag spikes and achieve more consistent speeds. This router can support speeds up to 5,400 Mbps! That's way more than what the typical household needs, but it's an option for tech heads and gamers.

To save money on equipment fees, you can use own gear or use Astound’s free self-setup option, which is available in most areas. Using DIY install, you'll pay just $10 to activate your service. Astound Broadband even offers detailed online instructions and videos to make it easy to DIY install. If you do want professional help or your home isn’t already properly wired, professional installation starts around $80, which is about average.

Equipment and installation
4.5
A fee for self-installation, but good equipment at a decent price

CenturyLink installation is more or less on par with other providers in terms of installation procedures and costs. If your neighborhood is wired for only DSL with CenturyLink, you can have your internet service set up by a pro for somewhere between $129 and $300 based on the installation requirements. You can alternatively choose to do a self-install for $15.

If you live in an area wired for CenturyLink fiber, your pro installation and equipment rental are free, and you may be able to self-install for free. You could also wrangle unlimited data and an included mesh wireless network if you sign a contract, so be sure to ask. This is about on par with other fiber internet providers.

Find out whether you need a professional to come by or if you can handle setup yourself.

As for equipment, the CenturyLink modem and router are also pretty standard stuff. The company charges around $15 per month for equipment rentals for DSL customers. The gear is nothing to write home about, but it works. You can also buy the modem outright from CenturyLink for up to $200—whether this is a good deal for you depends on how long you plan to have CenturyLink as a provider.

We don’t particularly recommend buying your own router. Both the DSL and fiber services require a modem certified by CenturyLink to function, so you may as well save some money and use the built-in wireless router.

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.

Award-winning customer service

Astound has (sorry in advance) astounding customer service. This company won fifth place in PCMag's Reader's Choice award in 2022 (2), and before it consolidated them under the Astound brand, Grande, Wave, RCN, and WOW! were all recognized in 2021 (3) and we can see why Astound is a fan favorite. You don't have to sign a contract if you don't want to, your plan comes with a 30-day money-back guarantee, and if your technician is late for your appointment, Astound will pay you $20 for the inconvenience. Put it all together, and you get a top-notch customer experience.

Customer experience
3.0
Below-average customer service

CenturyLink consistently scores slightly below average in customer satisfaction (2), largely due to complaints about a lack of responsiveness regarding customer service. The service also gets a lot of complaints from new fiber internet customers, but complaints are very common industry-wide.

CenturyLink hires techs and contractors from around the country, so some inconsistency is expected. It redeems itself slightly, though, with an easy-to-use support page.

The company is expanding and we hear that many new cities will have fiber internet hookups from CenturyLink within the next few years. If you can get only DSL, though, you may have a connection as slow as 3 Mbps or one as fast as 100 Mbps, with huge variation in latency depending on how far you are from the nearest access point.

We like that CenturyLink provides DSL to customers who may have no other option, but we don't recommend the DSL offering if you have access to cable or fiber internet from another provider.

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.
