Cable internet, like that of Xfinity, is a close second to fiber in terms of speed and reliability. In many areas, Connecticut included, it also has the advantage of greater availability and lower introductory pricing.

T-Mobile Home Internet is an ideal choice for broadband in suburban and rural Connecticut. Considering the low pricing and decent speed potential, you may also find it to be a suitable alternative to the big cable or fiber providers in your area.

Top Connecticut internet provider honorable mentions

Cheap internet options in Connecticut

Cable internet is often the go-to for cheap internet, and that’s the case in Connecticut as Xfinity, Optimum 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 and Optimum have a starting price of $40 per month, but Optimum advertises a bit more speed (300Mbps compared to 250Mbps with Cox). If you plan on renting Wi-Fi equipment, Optimum’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 max speeds (up to 500Mbps with Frontier Fiber and GoNetspeed), the extra cost may be well worth it.

How to find internet deals and promotions in Connecticut

The best internet deals and the top promotions in Connecticut depend on what discounts are available during that time period. Most deals are short-lived, but we look frequently for the latest offers. 

Connecticut internet providers, such as Optimum and Xfinity, may offer lower introductory pricing or special offers for a limited time. Many, however, including Frontier, Cox and GoNetspeed, run the same standard pricing year-round.

How fast is Connecticut broadband?

Ookla speed test data from Q3 2023 ranked Connecticut third-fastest among all US states and Washington, DC, with a median download speed of 229Mbps. That’s faster than the national average (213Mbps) and below only Rhode Island (230Mbps) and Florida (240Mbps).

Frontier had the fastest median download speed in the state at 271Mbps, 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 videoconferencing, 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 — and that 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.

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 answer to those questions is often layered and complex, the providers who 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, though 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, though less widely available in Connecticut than Xfinity, also offer low-cost plans up to 250Mbps and 300Mbps, respectively, starting at $40 per month.

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