Waterbury in Connecticut
Waterbury now has three wired networks, and how many of them reach a given address varies across the city. GoNetspeed, absent from the first National Broadband Map in 2022, reports fiber at 43.5% of the city's homes and businesses, laid largely over Frontier's fiber and Xfinity's cable. At 15.6%1 of locations Xfinity is still the only wired provider at 100/20 Mbps.
Three wires, two wires or one
The number of wired internet providers at a Waterbury address varies from one location to the next. As of June 30, 2026, the FCC data show three or more wired providers offering at least 100/20 Mbps at 41.0% of the city's 26,149 homes and businesses, exactly two at 43.3% and only one at 15.6%. Almost none, 0.1%1, have no wired option at that speed.

| Area | None | One | Two | Three or more |

| Waterbury | 0.1% | 15.6% | 43.3% | 41.0% |
| Hartford | 0.4% | 24.8% | 68.6% | 6.2% |
| Stamford | 4.8% | 16.3% | 78.9% | 0.0% |
| Connecticut | 1.3% | 17.9% | 43.0% | 37.8% |
| United States | 7.8% | 36.6% | 44.6% | 11.1% |
Statewide, 37.8% of Connecticut's locations have three or more wired choices at 100/20 Mbps and 17.9% have one, so Waterbury sits close to the state on both. Hartford, with a single-wire share of 24.8%, and Stamford, at 16.3%1, have a larger share of locations with one wire than Waterbury.
The three networks behind those counts are Xfinity's cable, which reaches 99.8% of locations; Frontier, which reports fiber at 81.7% and DSL over copper phone lines in part of the city; and GoNetspeed, which reports fiber at 43.5%. Where a location has a third wired choice, it is almost always GoNetspeed. Where it has only one, that one is Xfinity: it is the sole wired provider at 100/20 Mbps at 15.6%1 of locations, all of them places where neither Frontier nor GoNetspeed reports fiber.

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 (Viasat, Starlink, HughesNet) report service at nearly every location and are left out of the table.
"Available" here means the provider reports that it can install service within ten business days. The figures cover locations inside the city limits as drawn for the 2020 Census, in FCC revision November 10, 2026, and can be challenged on the FCC map.
GoNetspeed arrived where fiber already ran
GoNetspeed reported no service in Waterbury in the June 2022 map; it now reports 11,383 locations, all fiber, with advertised downloads up to 6 Gbps. Its network adds a second fiber line more often than it brings fiber to a location for the first time. Two or more fiber networks are reported at 41.0% of locations, almost the whole of GoNetspeed's 43.5%, against 0.0% in 2022. The share with three or more wired choices at 100/20 Mbps rose from 0.1%2 to 41.0%1 over the same period.
Frontier's footprint barely moved in size, but its technology did. DSL was reported at 73.3% of Waterbury's locations in June 2022 and at 18.0% in June 2026, while fiber from any provider rose from 67.6%2 to 84.3%. Frontier advertises up to 7 Gbps on fiber in the city. The fiber share is 119th highest among large cities and slightly above Connecticut's 82.1%1.

| Gigabit (1,000/100) | 67.6% | 97.4% | 98.0% | 30.5 pts |
Almost all of that change happened before the end of 2025. Between December 31, 2025 and June 30, 2026, the fiber share moved by 0.0 percentage points and the three-or-more share by 0.1 percentage points1.
Gigabit uploads beyond the fiber footprint
The FCC's gigabit tier, 1,000 Mbps down and at least 100 Mbps up, is advertised at 98.0% of Waterbury's locations, up from 67.6%2 in 2022. That is more than the fiber share, because Xfinity reports 1,000/100 service on its cable network in part of the city as well; the cable company's fastest advertised tier here is 2 Gbps. Symmetrical 100/100 Mbps wired service is reported at 98.0%1. These are maximum speeds that providers advertise, not measurements of what a connection delivers.
| Measure | Waterbury | Connecticut | United States | Rank among largest cities |
|---|---|---|---|---|
| Gigabit (1,000/100) | 98.0% | 92.9% | 72.3% | 59th of 343 |
| Wired 100/100 Mbps | 98.0% | 93.0% | 73.7% | 59th of 343 |

5G home internet is thin at 100/20
Fixed wireless from the mobile carriers is a smaller factor in Waterbury than in most large cities. Only 3 providers report it, a count tied for 2nd lowest among large cities, and it is reported at 78.2% of locations, down from 93.7%2 in 2022 and 88.2% at the end of 2025. Fixed wireless at 100/20 Mbps or faster fell from 35.7%3 to 18.0% of locations in those six months, against 24.6% across Connecticut and 47.9%1 nationally.

T-Mobile reports home internet at 69.6% of locations with 100/20 Mbps at 12.5%; AT&T, which reported no service here in 2022, at 35.9% with 100/20 at 2.2%; Verizon at 9.1% with 100/20 at 5.4%1. Wireless capacity is shared on each tower sector, so the carriers decide sign-ups address by address.
Subscriptions rose sharply since 2019
The Census Bureau's American Community Survey counts households, not locations, and asks what kind of internet subscription they have. In its 2019 survey, 23.9% of Waterbury households had no internet subscription (margin of error ±4.4 percentage points); in 2025 the figure was 7.8% (±3.0 percentage points). Households with a broadband subscription of any type rose from 75.4%4 to 92.2%5. The ranges do not overlap, so the increase is clear even with survey error.

Waterbury still trails the state on wired subscriptions: 74.4% of households paid for cable, fiber or DSL in 2025 (±3.0 percentage points), against 80.3% across Connecticut, and 14.0%5 relied on a cellular data plan alone. Figures from the five-year survey for 2020–2024 show a higher no-subscription share, 14.4%6, because it averages earlier years.
