Internet providers and fiber in Ontario, California
Fiber is available at 81.9% of the 44,600 homes and businesses the FCC counts in Ontario, and wired broadband of at least 100/20 Mbps at 95.3%. 78.2% of locations have a choice of two or more wired providers at that speed; at 17.2% there is only one.1

Ontario in California
Most of Ontario has two wires to choose from: Frontier's fiber, reported at 77.2% of the city's homes and businesses, and Spectrum's cable, at 93.0%. What sets it apart from its Inland Empire neighbors is a third wire. The fiber of Inyo Networks, which runs the city's own OntarioNet, did not appear in the 2022 filings and now reaches 12.1%1 of locations.
Who reports service in Ontario
The FCC counts 44,600 homes and businesses in Ontario, each a "location" on the National Broadband Map. As of June 30, 2026 (file revision of November 10, 2026), 8 companies report land-based internet service at some of them, 5 of them over wires. Two networks cover nearly the whole city. Spectrum reports service at 93.0%, mostly over cable, with downloads advertised up to 1 Gbps. Frontier reports 77.2%, and at 77.2% of locations that service is fiber, advertised up to 7 Gbps1.

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.
A provider counts as available where it tells the FCC it could connect a location within ten business days for a standard installation. Those filings can be challenged on the FCC map, which is also the place to check one address. Satellite service is reported at every location and is left out of the counts below.
Fiber or cable at almost every address
Fiber from any provider reaches 81.9% of Ontario's locations, a share ranked tied for 134th highest among the 343 cities of 100,000 or more and well above California's 47.8%. Put Frontier's fiber beside Spectrum's cable and the typical Ontario location has exactly two wired providers offering 100/20 Mbps: that is the case at 67.8% of them. Two or more are reported at 78.2%, against 49.9%1 statewide.

Outside Frontier's fiber, Spectrum is often the only fast wire. It is the only wired provider at 100/20 Mbps for 15.0% of locations, and the single-wire share as a whole, 17.2%, is a little higher than the 12.4% of June 2022. Copper has almost left the filings: DSL was reported at 38.4%2 of locations in 2022 and at 0.1%1 now.
A city network adds a third wire
Ontario's most distinctive change since 2022 is a third wired option. The city says that in December 2015 it became one of California's first municipal fiber networks to deliver gigabit service, and that OntarioNet offers fiber to communities in Ontario Ranch; its fiber page describes a city-owned network meant ultimately to reach all city facilities, residents and businesses. A 2021 Culver City bulletin names Inyo Networks, now called Onward, as OntarioNet's network manager and service provider.
In the FCC data, Inyo Networks went from no reported locations in June 2022 to 5,385 (12.1%), all of them fiber advertised up to 1 Gbps. Over the same period the share of locations with three or more wired providers at 100/20 Mbps rose from 0.2% to 10.3%, and the share with two or more fiber providers from 0.0%2 to 11.8% (5,262 locations). The FCC's count of locations in the city grew by 4,9071 over those four years.
Nearby cities show almost no overlap of this kind. Pomona has as much fiber as Ontario, but two or more fiber providers at only 0.3%1 of locations.

Gigabit uploads slipped in the latest filing
Nearly every location has a 1 Gbps download advertised (95.3%), and at 78.6% the fastest advertised download is 2 Gbps or more. The stricter gigabit measure, 1,000 Mbps down with at least 100 Mbps up, is reported at 81.5%. That share was 88.9% on December 31, 2025, a fall of 7.4 percentage points, ranked 6th lowest among the changes in large cities. Symmetrical 100/100 Mbps service moved the same way, from 88.0%3 to 81.5%1, while the fiber share itself was steady. The filings record the change but not its reason. All speeds here are providers' advertised maximums, not measurements.

Wireless: fewer licensed signals, a radio network filed for business
Ultimate Internet Access Inc lists an unlicensed radio network across the city, advertised up to 100 Mbps, but files it as business-only service, so this page counts only its small residential fiber footprint (1.9%), advertised up to 8 Gbps1.
Licensed fixed wireless, the category that includes 5G home internet, has shrunk. It was reported at 91.1% of locations in 2022 and is at 75.6% now, 7th lowest among large cities. T-Mobile reports it at 61.6% of locations, AT&T at most of its 45.4% footprint (AT&T reports DSL at only a handful of addresses) and Verizon at 7.0%. Licensed wireless at 100/20 Mbps or faster is reported at 27.9%1, up from 7.1%2 in 2022 but down from 47.3%3 on December 31, 2025. Carriers limit sign-ups where a tower sector is busy, so a location on the map is not a promised connection.

The locations the federal program counts as unserved
360 Ontario locations (0.8%) count as unserved under the definitions of the federal BEAD program, a share ranked tied for 8th highest among large cities; statewide the unserved share is 1.6%. BEAD does not count unlicensed fixed wireless as reliable service. In all, 2,096 locations have no wired provider at 100/20 Mbps; 296 of them reach that speed by fixed wireless, 1,8001 have no land-based option at that speed in the residential count, and no location in the city is left with satellite alone.

What households subscribe to
The Census Bureau's 2025 survey counts households, not locations, and gives estimates with margins of error. In Ontario, 82.7% of households subscribed to cable, fiber or DSL (±2.7 percentage points), up from 72.7% in 2019 (±3.2 percentage points); the two ranges do not overlap. Households relying only on a cellular data plan were estimated at 10.2% (±2.8 percentage points), against 14.3% in 2019, and those with no subscription at 5.6% (±2.3 percentage points4), against 10.1%5 in 2019; with these margins, neither change is clearly established.
The California page maps every county, including San Bernardino County, where Ontario sits, and the state's BEAD plan. Neighboring Rancho Cucamonga and Fontana have far less fiber.

Checking one address in Ontario
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.
