Internet in Boise, Idaho

Who reports service in Boise

As of June 30, 2026 (FCC revision of November 10, 2026), 12 companies report fixed internet service on the ground somewhere among Boise's 83,984 homes and businesses. One of them is everywhere. Sparklight reports service at 99.1%¹ of locations, nearly all of it cable, and offers 100/20 Mbps across that whole footprint. Every other company reports a partial map.

A share in this table is the share of locations where a company tells the FCC it could start a standard installation within ten business days. The companies file these maps themselves and anyone can challenge them. They carry no prices and no measured speeds. The three satellite companies list every location in the city, as they do nationwide; on the ground, every Boise location has some terrestrial service of at least 100/20 Mbps, wired or wireless, except 37¹ of them.

Who builds fiber, and for whom

Fiber is reported at 36.1% of Boise's locations, the 50th lowest share among the 343 US cities of 100,000 or more; the median city is at 74.0%. 5¹ companies report fiber in the city:

• AT&T reports fiber at 25.1%, with downloads advertised up to 8 Gbps. About half of these records carry the Quantum Fiber brand and half AT&T's own. In the December 31, 2025 files, nearly the same Boise fiber footprint was filed by CenturyLink, under the Quantum Fiber and CenturyLink brands; AT&T reported nothing in the city in June 2022, when CenturyLink filed fiber at a smaller part of Boise. AT&T's appearance is mostly a change of filer, not a new network.
• Fatbeam reports fiber at 7.0%, nearly all of it filed as residential service at up to 5 Gbps, a footprint it reached between 2022 and 2025.
• TDS reports fiber at 4.0%, up to 8 Gbps. Sparklight itself reports fiber at 1.3%¹.

The rise from 18.1%² in June 2022 to 36.1% now, 18.0 percentage points, comes from Fatbeam, TDS and the AT&T network. Syringa Networks also files fiber at many Boise locations, but every one of those records is coded as business-only service, so it is not counted on this page. Two or more fiber networks overlap at 1.4%¹ of locations. Whether one house or apartment building has a residential fiber plan is an address question that only the provider and the FCC map can answer.

Behind its own suburbs

Boise trails the two other large cities of the Treasure Valley on fiber. Meridian reports fiber at 75.1% of locations and Nampa at 74.0%, both well above the state's 46.5%. The builders differ by city. In Nampa, TDS reports fiber at 61.7% of locations; in Meridian, Fatbeam reports it at 34.7% and Sparklight at 19.5%¹. Neither network reaches far into Boise.

The gap carries over to choice. Two or more wired providers at 100/20 Mbps are reported at 74.2% of Meridian's locations and 74.7% of Nampa's, against 41.3%¹ in Boise.

Sparklight alone at a shrinking share

In June 2022, 74.7% of Boise's locations had exactly one wired provider at 100/20 Mbps. As of June 30, 2026 that share is 57.9%, and Sparklight is the single wire at 57.8%. Two or more wired choices rose from 24.8% to 41.3%, a gain tied for 146th highest among large cities, and three or more from 0.2%² to 1.7%¹.

CenturyLink's copper does not add a fast choice. DSL is still reported at 71.5% of locations, a share tied for 68th highest among large cities, but CenturyLink offers 100/20 Mbps at only 6.9%, with a fastest advertised download of 140 Mbps¹.

Gigabit downloads, 50 Mbps uploads

A 1 Gbps download is advertised at 99.1% of Boise's locations, because Sparklight advertises it across its cable network. The upload side is different. In the FCC's Idaho files, Sparklight's Boise cable records list 1 Gbps down and 50 Mbps up, which falls short of the FCC's gigabit tier of 1,000/100 Mbps. That tier is reported at 37.2% of locations, the 17th lowest share among large cities, against 50.0% statewide and 72.3% nationally. Symmetrical service of 100/100 Mbps or more is reported at 36.4%¹, in practice wherever fiber is. All are maximum speeds that providers advertise, not measurements.

Fixed wireless from carriers and local companies

Licensed fixed wireless, the category that includes 5G home internet, is reported at 96.5% of locations. Verizon reports it at 86.9% and offers 100/20 Mbps at 36.0%; T-Mobile reports 69.5%, with 100/20 at 9.9%¹. AT&T reports fixed wireless across a wider area than its fiber.

Two local companies add to the list. White Cloud Communications reports licensed fixed wireless at 44.1% of locations, up to 200 Mbps. Anthem Broadband reports service over unlicensed spectrum at 37.5%, advertised up to 1 Gbps. Rise Broadband reports 25.4%¹, with 100/20 Mbps at almost none of them. A wireless network's capacity is shared by everyone on a sector, so an FCC availability record does not guarantee a sign-up at every address.

What Boise households subscribe to

In the Census Bureau's 2025 American Community Survey, 80.2% of Boise households subscribed to cable, fiber or DSL (margin of error ±1.9 percentage points), 11.4% relied on a cellular data plan alone and 4.5% had no internet subscription (margin of error ±1.2 percentage points⁴). Survey households and FCC locations are counted differently, so the two sets of numbers describe the same city without matching one to one.
