FCC National Broadband Map, availability as of June 30, 2026 (data revised November 10, 2026), as reported by providers.
Stamford in Connecticut
Two companies wire Stamford. Optimum reports fiber at 91.2% of the city's homes and businesses and Frontier at 79.3%, so fiber reaches most addresses and most have two fast wired choices. A third wired provider at 100/20 Mbps is reported at 0.0% of locations, in a state where 37.8%1 have one.
Optimum, Frontier and a short list after them
Optimum reports service at 94.8% of Stamford's 25,556 homes and businesses, with fiber at 91.2% and a cable network alongside it; its fastest advertised download is 10 Gbps. Frontier reports service at 81.9%: fiber at 79.3%, up to 7 Gbps1, and DSL over copper phone lines at part of the remainder.

Source: FCC, National Broadband Map, data as of June 30, 2026. Share of the area's broadband serviceable locations where the provider reports service as of June 30, 2026. "Only wired option" is the share of locations where it is the single wired provider at 100/20 Mbps. Provider-reported and challengeable; speeds are advertised maximums, not measured; no prices. Satellite providers (HughesNet, Starlink) report service at nearly every location and are left out of the table.
After those two the list is almost empty. Xfinity, for example, reports 6 locations. The mobile carriers fill out the count of 71 terrestrial providers with fixed wireless.
The data are the providers' own filings as of June 30, 2026, in the FCC revision of November 10, 2026, for locations inside Stamford's city limits as drawn for the 2020 Census. A provider that lists a location says it can install service there within ten business days. Listings can be challenged on the FCC National Broadband Map, which also shows the providers reported at any single address.
Two fast wires or one, almost never three
Connecticut has more wired competition than almost any state: 37.8% of its locations have three or more wired providers at 100/20 Mbps, the 2nd highest share among the states. Stamford sits at the other end. That share here is 0.0%, tied for the lowest among the 343 cities of 100,000 or more, against 68.6% in Bridgeport and 46.2%1 in New Haven, where Xfinity and GoNetspeed also report wired service.

What Stamford has instead is a near-even split between two choices and one. Exactly two wired providers offer 100/20 Mbps at 78.9% of locations, the 55th highest share among large cities, and the average location has 1.74. At the other 4,169 locations, 15.9% of the city, Optimum is the only wired provider at that speed; those are, in effect, the places Frontier's fiber does not reach. 1,2261 locations have no wired 100/20 provider at all.
Source: FCC, National Broadband Map, data as of June 30, 2026. Different wired providers (fiber, cable or DSL; FCC provider IDs) reporting 100 Mbps down and 20 Mbps up or more at the same location. Fixed wireless and satellite are not counted.

Fiber and gigabit uploads at most addresses
Fiber is reported at 93.5% of locations, a share that ranks tied for 37th highest among large cities. It was already 95.4%2 in the first National Broadband Map, as of June 30, 2022, and has slipped by 1.9 percentage points1 since; the larger change was in advertised speed.
In 2022, 30.0% of locations had a fastest advertised download between 940 Mbps and 2 Gbps, and 69.6%2 had 2 Gbps or more. By June 2026 the top tier, 2 Gbps or more, was advertised at 93.5%. Gigabit service with uploads of 100 Mbps or more, the FCC's 1,000/100 tier, and symmetrical 100/100 Mbps service are both reported at 93.5% of locations, compared with 92.9% and 93.0%1 statewide. All of these are the providers' advertised maximums, not measured speeds.

Because Optimum reports fiber and cable at nearly the same locations, a listing for fiber does not say which of the two a given building is wired with. In an apartment building, the FCC location is the building, not each unit.
Copper and fixed wireless have pulled back
Two other networks shrank in the filings since 2022. DSL was reported at 75.3% of Stamford locations in June 2022 and at 11.4% in June 2026, a drop of 64.0 percentage points, larger than Connecticut's 49.1 percentage points. DSL is now reported at 2,902 locations, and Frontier is the provider at essentially all of them. The number of wired providers reporting any service in the city is the same as in 2022, 5, and the share with two or more fiber networks rose from 67.9%2 to 77.0%1.

Licensed fixed wireless, the category that includes 5G home internet, fell from 97.2%2 of locations to 73.1%, the 4th lowest1 share among large cities. The filings record where carriers report service, not why a report changed.
5G home internet: wide reports, few at 100/20
3 carriers report licensed fixed wireless home internet in Stamford, a count tied for 2nd lowest among large cities. T-Mobile reports it at 66.9% of locations but offers 100/20 Mbps at 21.2%. AT&T, which reported no service in the city in 2022, now lists 8,923 locations, 34.9% of the total, with 100/20 at 3.4%; both carriers advertise up to 100 Mbps. Verizon reports 8.0%1 of locations, almost all of them by fixed wireless.
Combined, fixed wireless of at least 100/20 Mbps is reported at 26.2%1 of locations, up from 10.0%2 in 2022 but down from 33.7%3 in the December 2025 release. A tower sector's capacity is shared, so carriers decide eligibility by address. Satellite from HughesNet, Starlink and Viasat is reported at every location, and no location in Stamford depends on satellite or fixed wireless alone.
Stamford beside Connecticut's other large cities
Connecticut's five cities of 100,000 or more all have fiber at most locations, but they differ in how many networks compete. Stamford ties Bridgeport for the most fiber and has the least three-way choice of the group; Hartford has the largest share of one-wire locations.
| Area | Fiber available | One wired choice | Two wired choices | Three or more wired choices | DSL available |

The Western Connecticut planning region, which includes Stamford, is close to the city on choice: fiber at 85.1% of locations and two or more wired choices at 100/20 Mbps at 77.8%1.
What Stamford households subscribe to
In the Census Bureau's 2025 American Community Survey, 84.0% of Stamford households subscribed to cable, fiber or DSL (margin of error ±3.0 percentage points) and 8.9% relied only on a cellular data plan (±2.5 percentage points). Households with no internet subscription were estimated at 3.5% (±1.7 percentage points4), down from 8.2% (±2.4 percentage points5) in 2019; the two ranges do not overlap. The survey counts households over a year and the FCC counts locations on one date, so the two are not directly comparable.

Checking one address in Stamford
The figures on this page describe the whole area. Which providers report service at a single home or apartment is shown only on the FCC's own map: search the address at broadbandmap.fcc.gov. If a provider is listed there but cannot actually connect you within ten business days, or the location is missing or misplaced, the map has a button to file a challenge; providers must respond, and corrections flow into later releases. Prices and plans are not part of the FCC data: each provider must show them on its broadband facts label at the point of sale.
