Internet providers measured in Arizona, ranked by speed

Median real-world speeds for the 7 fixed home internet providers with at least 100 distinct connections in Arizona, fastest first. These are the speeds their customers measured, not advertised plan speeds, and not a statement of who can be bought at a given address.

#ProviderDownloadUploadLatencyConnections
1 Wyyerd Fiber 287.9 178.8 19 ms 250+
2 Comcast 254.5 42.6 31 ms 250+
3 Cox 228.4 57.1 19 ms 2.5k+
4 Spectrum 192.4 24.6 25 ms 100+
5 Sparklight 192.3 32.1 24 ms 100+
6 CenturyLink 104.9 79.1 19 ms 1k+
7 Starlink 19.7 12.1 34 ms 250+

Starlink is a satellite service: a single browser stream over a link with a long round trip measures well below the figures satellite operators quote, and the latency column shows why.

Measured in Arizona and named rather than ranked: AT&T, T-Mobile US, Verizon. In Arizona each of these is the operator's mobile network rather than a wired home line, and a browser test cannot tell a phone from a 5G home gateway on the same network. Ranking them beside fibre and cable would compare two different products.

Also measured, with too few connections for a median we would stand behind: Optimum.

Internet in Arizona: what the data shows

In Arizona, the median real-world download speed is 136.0 Mbps, 7% below the median published state of 145.6 Mbps, ranking #28 of the 39 states and districts with enough data to publish.

Arizona's fastest is Wyyerd Fiber at 287.9 Mbps, ahead of both national cable operators competing in the state.

Uploads median 35.4 Mbps and latency 29 ms.

Desktop and mobile tests run at about the same median speed, with mobile making up 32% of tests.

Across the 7 fixed providers with enough connections to rank here, medians run from 287.9 Mbps (Wyyerd Fiber) down to 19.7 Mbps (Starlink), a 14.6× spread inside one state. Which network reaches an address matters more here than which state the address is in.

The Arizona sample carries enough tests to name 11 providers, 8 counties and 17 cities and localities. Phoenix was its most-used test server, taking 66% of the tests among the five busiest.

Figures are medians of 10k+ browser-based tests from 10k+ distinct connections, first half of 2026. Each connection counts at most three times, third-party sources are capped, and datacenter networks are excluded, so one busy line cannot move a state. That makes these numbers a different series from the national figure on the United States page, and they are not directly comparable to it.

Frequently asked questions

What is the average internet speed in Arizona?

The median real-world download speed in Arizona is 136.0 Mbps, with 35.4 Mbps upload and 29 ms latency, measured from 10k+ browser-based speed tests on SpeedOf.Me.

Where does Arizona rank among US states?

Arizona ranks #28 of the 39 states and districts we publish, 7% below the median published state. We publish a state only where at least 2,000 distinct connections back the number, so 12 of the 51 are not listed at all.

Why is this lower than the speed my provider advertises?

An advertised speed is the maximum the line can carry. This is a real-world measurement through a browser to neutral servers on the open internet, which is what a video call, a download or a game actually gets. Wi-Fi, the device and time of day all sit between the two.

Which internet provider is fastest in Arizona?

Of the fixed home internet providers with at least 100 distinct connections in Arizona, Wyyerd Fiber has the highest median real-world download speed at 287.9 Mbps, ahead of Comcast at 254.5 Mbps. That is the median its customers measured here, not an advertised plan speed, and a provider is only as fast as the line that reaches your address.

Which internet providers were measured in Arizona?

11 providers had enough tests in Arizona to name: AT&T, CenturyLink, Comcast, Cox, Optimum, Sparklight, Spectrum, Starlink, T-Mobile US, Verizon, Wyyerd Fiber. 7 of them carry a ranked median speed on this page: the rest are either a carrier's mobile network in Arizona rather than a wired home line, or below the 100 distinct connections we require before publishing a median. That list is not a market-share estimate or a statement of who can be bought at a given address.

Are speeds on phones lower than on computers in Arizona?

Tests run on phones and tablets, over home Wi-Fi or a cellular connection, are 32% of the Arizona sample and median 135.5 Mbps. Tests run on desktops and laptops, which are almost always on a fixed line's Wi-Fi, median 134.5 Mbps. This is a device comparison, not a comparison of providers.
