What is the best internet provider in Connecticut?

Looking for the best internet providers in Connecticut? After reviewing the available options, CNET has chosen Frontier Fiber as the top choice for internet for most households in Connecticut. Along with an extensive fiber-optic network covering much of the state, Frontier Fiber offers low, stable pricing on fast, symmetrical speeds and simple service terms that include equipment rental and unlimited data at no extra cost.

The fiber internet provider is also one of Connecticut's fastest internet service providers, offering speeds up to 5,000 megabits per second starting at $155 per month. However, that's not the fastest speed overall, as Optimum also offers fiber internet in Connecticut with speeds up to 8Gbps.

Xfinity is the best source of cheap internet in Connecticut, with service starting at $25 per month for up to 200Mbps. While slightly more expensive, Optimum offers a bit more speed, up to 300Mbps, starting at $40 per month and includes Wi-Fi equipment at no extra cost. Cox rounds out the list of cable internet providers in Connecticut with a starting price of $50 per month for speeds up to 100 or 250Mbps, depending on your location.

Whether looking for the cheapest internet in Connecticut, the fastest plans or simply a good mix of speed and value, you’ll find everything you need to know about the state’s leading internet providers below.

Top Connecticut internet provider honorable mentions

• Cox: The third-largest cable internet provider in Connecticut, Cox serves parts of Hartford and surrounding suburbs to the north, south and east. Plans start at $50 to $150 per month (or lower in select areas) for speeds of 100Mbps to 1,000Mbps. However, some areas can expect speeds of up to 2,000Mbps. All plans come with a monthly data cap of 1.25TB, and a two-year contract may be required to get the lowest pricing on select plans.
• Frontier: As mentioned above, Frontier covers much of Connecticut, but not all service areas are fiber-eligible. The remaining areas must rely on Frontier’s slower, less reliable DSL network. Speeds vary, but don’t expect anything close to what you would get with fiber service. 
• GoNetspeed: Local fiber ISP GoNetspeed offers 500, 750 and 1,000Mbps plans starting at $40, $50 and $60 per month, respectively. Only select areas can expect up to 2,000Mbps for $100 per month. That’s a good deal regardless of your chosen plan, but service may be tough to come by. Only around 13% of Connecticut households are currently eligible for GoNetspeed, according to the FCC.
• Optimum: Altice USA brand Optimum has a large presence in the greater NYC area, and that coverage extends into western Connecticut. Speeds and pricing are as good as any, especially in areas where fiber service and speeds up to 8Gbps are available. Service terms are also favorable -- no equipment fees, data caps or contracts -- but the low customer satisfaction scores may be cause for concern.
• Verizon 5G Home Internet: Select areas, including much of Bridgeport, Hartford and Stamford, are serviceable for wireless home internet via Verizon’s 5G Ultra Wideband network. Service starts at $50 per month for speeds ranging from 80 to 300Mbps, or you can upgrade to 300 to 1,000Mbps at $70 monthly. There are no equipment fees, data caps or contracts. Qualifying Verizon mobile customers can receive an additional discount on Verizon home internet service.  
• Satellite internet: Nearly 99% of Connecticut households are serviceable for cable and/or fiber internet service, so you likely won’t have to rely on satellite internet. If no other internet service is available, however, there’s always Hughesnet or Viasat -- provided you have a clear view of the southern sky. Starlink may be another satellite option, with a faster speed potential, more data (unlimited) and lower latency than Hughesnet or Viasat.

Internet breakdown by city in Connecticut

It’s hard to cover the broadband options of an entire state and still give individual cities the attention they deserve. That’s why we also compile lists of the best internet providers in cities across the US, including those in Connecticut. We tackle details such as internet connection types, max speeds and cheapest providers. Check back later if you don’t find the city you’re looking for below. We’re working to add more locations every week. 

Cheap internet options in Connecticut

Cable internet is often the go-to for cheap internet, and that’s the case in Connecticut as Xfinity and Cox have the cheapest internet plans of any major ISP in the state.

Xfinity internet service costs $25 per month for download speeds up to 200Mbps. Cox has a starting price of $50 per month for 100Mbps. However, if you're looking for a fiber connection, Frontier offers download speeds of 500Mbps at $25 per month for the first year. If you plan on renting Wi-Fi equipment, Frontier's plan is the better deal than Xfinity or Cox since there's no rental fee. 

Starting prices from many other Connecticut ISPs begin at $50 per month. That’s double Xfinity’s lowest price, but when you consider equipment costs (or lack thereof), plus the maximum speeds (up to 100Mbps with Hughesnet and 150Mbps with Viasat), the extra cost may be well worth it.

How fast is Connecticut broadband?

Ookla speed test data from Q4 2023 ranked Connecticut second-fastest among all US states and Washington, DC, with a median download speed of 244Mbps. That’s faster than the national average (237Mbps) and below only Florida (238Mbps) and Delaware (237Mbps).

Frontier had the fastest median download speed in the state at 292Mbps, but plenty of other providers, including Cox, Optimum, GoNetspeed and even Verizon 5G Home Internet, offer plans with faster speeds than the state average.

What’s a good internet speed?

Most internet connection plans can now handle basic productivity and communication tasks. If you're looking for an internet plan that can accommodate video conferencing, streaming video or gaming, you'll have a better experience with a more robust connection. Here's an overview of the recommended minimum download speeds for various applications, according to the FCC. Note that these are only guidelines; internet speed, service and performance vary by connection type, provider and address.

For more information, refer to our guide on how much internet speed you really need.

• 0 to 5Mbps allows you to tackle the basics: browsing the internet, sending and receiving email and streaming low-quality video.
• 5 to 40Mbps gives you higher-quality video streaming and video conferencing.
• 40 to 100Mbps should give one user sufficient bandwidth to satisfy the demands of modern telecommuting, video streaming and online gaming. 
• 100 to 500Mbps allows one to two users to simultaneously engage in high-bandwidth activities like video conferencing, streaming and online gaming. 
• 500 to 1,000Mbps allows three or more users to engage in high-bandwidth activities at the same time.

How CNET chose the best internet providers in Connecticut

Internet service providers are numerous and regional. Unlike the latest smartphone, laptop, router or kitchen tool, it’s impractical to personally test every ISP in a given city. So what’s our approach? We start by researching the pricing, availability and speed information, drawing on our own historical ISP data, the provider sites and mapping information from the Federal Communications Commission at FCC.gov.

But it doesn’t end there. We go to the FCC’s website to check our data and ensure we consider every ISP that provides service in an area. We also input local addresses on provider websites to find specific options for residents. We look at sources, including the American Customer Satisfaction Index and J.D. Power, to evaluate how happy customers are with an ISP’s service. ISP plans and prices are subject to frequent changes; all information provided is accurate as of publication.

Once we have this localized information, we ask three main questions:

1. Does the provider offer access to reasonably fast internet speeds?
2. Do customers get decent value for what they’re paying?
3. Are customers happy with their service?

While the answers to those questions are often layered and complex, the providers that come closest to “yes” on all three are the ones we recommend. When selecting the cheapest internet service, we look for the plans with the lowest monthly fee, although we also factor in things like price increases, equipment fees and contracts. Choosing the fastest internet service is relatively straightforward. We look at advertised upload and download speeds and consider real-world speed data from sources like Ookla and FCC reports.

What’s the final word on internet providers in Connecticut?

Frontier Fiber is the top choice for home internet in Connecticut thanks to its fast speeds (the fastest of any major ISP in the state, up to 5,000Mbps), competitive pricing and favorable service terms. 

While many Connecticut households are serviceable for Frontier Fiber, not all are. Xfinity also boasts high availability in Connecticut and has the cheapest internet plan in the state, starting at $25 per month for speeds up to 200Mbps. Cox and Optimum, although less widely available in Connecticut than Xfinity, also offer low-cost plans up to 250Mbps starting at $55 and 300Mbps starting at $100 per month, respectively.

With plans starting at $50 per month, wireless home internet from Verizon may also be a practical broadband option. Still, the overall value will depend on the available speeds at your address.
