Internet in Hartford, Connecticut

Xfinity everywhere, Frontier at most addresses

Xfinity reports service at 99.6% of Hartford's 18,043 homes and businesses, almost all of it over cable, with advertised downloads up to 2 Gbps on the few buildings it has wired with fiber. Frontier reports service at 77.6%: fiber at 74.3%, up to 7 Gbps, and DSL over copper phone lines at part of the city; DSL from any provider is reported at 3,316 locations. Behind them the wired list is short. GoNetspeed reports fiber at 1,214 locations, 6.7% of the city, and Cox reports cable at 40¹.

Each company reports its coverage to the FCC itself. The figures here are as of June 30, 2026, in the revision published November 10, 2026, and cover Hartford inside its 2020 Census boundary. Listing a building means the company says it can connect it within ten business days; anyone can dispute a listing on the FCC National Broadband Map.

A location is a structure, not a household: a house, an apartment building or a business counts once. The FCC counts 18,043¹ locations in Hartford, while the Census Bureau estimates 46,599 households (margin of error ±3,193³): a block of fifty apartments is one location on the map. Every share on this page is a share of locations.

The copper network turned into fiber

In the first National Broadband Map, as of June 30, 2022, DSL was reported at 66.2% of Hartford's locations and fiber at 45.7%². By June 30, 2026, DSL had fallen 47.8 percentage points to 18.4%, and fiber had risen 29.2 percentage points to 74.9%, a share that ranks tied for 167th highest among large cities. Statewide the pattern is the same and slightly further along: DSL fell 49.1 percentage points and fiber reached 82.1%, 4th highest¹ among the states.

The swap changed what a typical address can choose. In 2022, 52.7%² of locations had only one wired provider offering 100/20 Mbps; in 2026 the share is 24.8%, and two or more wired choices at that speed rose 29.2 percentage points to 74.8%. Nearly all of that change had happened by December 31, 2025: fiber has risen only 0.1 percentage points since then, and DSL has fallen another 1.4 percentage points¹.

Two wires, rarely three

Bridgeport and Stamford each have a second fiber builder, Optimum, alongside Frontier, and New Haven has GoNetspeed. Hartford has neither at scale. Only 3 providers report fiber anywhere in the city, a count tied for 28th lowest among the 343 cities of 100,000 or more, and two or more separate fiber networks reach just 6.2% of locations, mostly where GoNetspeed has built. The common case is exactly two wired providers at 100/20 Mbps, cable and fiber, at 68.6% of locations; three or more are reported at 6.2%¹.

At 4,470 locations, 24.8% of the city, Xfinity is the only wired provider offering 100/20 Mbps, the largest one-wire share among Connecticut's cities of 100,000 or more. Frontier is the only fast wire at 0.0% of locations: where its fiber runs, Xfinity's cable runs too. The surrounding Capitol planning region looks much like the city, with fiber at 77.1% of locations and one wired choice at 22.4%¹.

Fast uploads even without fiber

Wired service with uploads as fast as downloads, at least 100/100 Mbps, is reported at 98.5% of Hartford's locations, up from 45.7%² in 2022. In 2022 that share matched the fiber share almost exactly. Now it is well above fiber's 74.9%, and the wired networks at the locations without fiber are Xfinity's cable and, at some, Frontier's DSL, so the difference is on cable: Xfinity's Hartford filings list uploads of 100 Mbps or more where there is no fiber. Gigabit service with uploads of at least 100 Mbps, the FCC's 1,000/100 tier, is advertised at 98.5% of locations, a share that ranks tied for 47th highest among large cities, and the fastest advertised download is 2 Gbps or more at 98.5%¹. Every speed here is what a provider advertises as its top tier; none is a measurement.

Fixed wireless: wide reports, fewer at 100/20

3 mobile carriers report licensed fixed wireless, the category that includes 5G home internet, at 93.3% of locations. T-Mobile lists 79.2% of locations, with 100/20 Mbps at 12.5%. AT&T, which reported no service in Hartford in 2022 and has no wired network here, lists 50.4%, with 100/20 at 6.9%. Verizon covers less ground, 21.2%, but advertises up to 1 Gbps and offers 100/20 at 18.2%¹.

Fixed wireless at 100/20 Mbps from any carrier fell from 72.3%⁴ of locations in the December 2025 data to 33.8% in June 2026. The filings record where carriers say they can serve, not why the reports changed; a tower sector's capacity is shared, so eligibility is decided address by address. Only 6 locations in Hartford depend on satellite alone, and 23¹ on fixed wireless alone for 100/20 Mbps.

Wired everywhere, phones at home

Availability and subscription diverge more in Hartford than in most large cities. In the Census Bureau's 2025 American Community Survey, 68.8% of Hartford households subscribed to cable, fiber or DSL (margin of error ±7.1 percentage points), among the lowest estimates for a large city and well below Connecticut's 80.3% (±0.6 percentage points). Another 21.2% relied only on a cellular data plan (±4.5 percentage points), 10th highest among large cities, against 11.8%³ statewide.

Availability is a share of locations as of June 30, 2026 (FCC); subscriptions are a share of households from the American Community Survey, 2025 (whiskers: 90% margin of error).

Measure	Share	MOE

Households subscribing to cable, fiber or DSL (Census)	68.8%	±7.1
Households relying only on a cellular data plan	21.2%	±4.5
Households with no internet subscription	7.1%	±2.7

The devices tell the same story. 22.2% of households had a smartphone but no desktop, laptop or tablet (±4.8 percentage points), the 3rd highest estimate among large cities, and 7.5% had no computer, smartphone or tablet at all (±2.7 percentage points). The statewide figures are 8.6% and 3.5%³. Each Hartford estimate is further from the state than its margin of error, so the gaps are not sampling noise.

Subscriptions have risen even so. Households with any broadband subscription went from 80.9% (±3.3 percentage points) in 2019 to 92.9% (±2.8 percentage points) in 2025, and those with no subscription from 19.1%⁵ to 7.1%³. One source samples households across a year, the other lists buildings on a single date; subtracting one from the other would not yield a count of unconnected homes.

Hartford beside cities its size

Among the 343 cities of 100,000 or more, Hartford ranks tied for 42nd highest for cable and tied for 47th highest for 1,000/100 service, but only tied for 167th highest¹ for fiber. The table puts it beside the cities closest to it in size. The same FCC release is used for every city.

The Connecticut page covers all 9⁶ planning regions and the state's federal broadband programs; Bridgeport is the large city where competing fiber networks overlap most.
