Internet providers measured in Washington, ranked by speed
Median real-world speeds for the 5 fixed home internet providers with at least 100 distinct connections in Washington, 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.
| # | Provider | Download | Upload | Latency | Connections |
|---|---|---|---|---|---|
| 1 | Comcast | 223.0 | 45.4 | 20 ms | 2.5k+ |
| 2 | Astound Broadband | 188.4 | 20.7 | 21 ms | 250+ |
| 3 | Spectrum | 143.0 | 20.8 | 46 ms | 250+ |
| 4 | CenturyLink | 111.6 | 107.9 | 14 ms | 500+ |
| 5 | Starlink | 17.3 | 12.0 | 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 Washington and named rather than ranked: AT&T, T-Mobile US, Verizon. In Washington 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: Ziply Fiber.
Internet in Washington: what the data shows
In Washington, the median real-world download speed is 124.3 Mbps, 15% below the median published state of 145.6 Mbps, ranking #35 of the 39 states and districts with enough data to publish. That is among the slowest we publish.
Washington ranks five providers and cable leads them, with the fastest fibre in the state falling below the connection gate.
Uploads median 40.1 Mbps and latency 27 ms.
Desktop tests run about 1.3× faster than mobile, and mobile is 30% of tests.
Across the 5 fixed providers with enough connections to rank here, medians run from 223.0 Mbps (Comcast) down to 17.3 Mbps (Starlink), a 12.9× spread inside one state. Which network reaches an address matters more here than which state the address is in.
The Washington sample carries enough tests to name 9 providers, 14 counties and 17 cities and localities. Seattle was its most-used test server, taking 88% of the tests among the five busiest.
Figures are medians of 10k+ browser-based tests from 5k+ 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 Washington?
The median real-world download speed in Washington is 124.3 Mbps, with 40.1 Mbps upload and 27 ms latency, measured from 10k+ browser-based speed tests on SpeedOf.Me.
Where does Washington rank among US states?
Washington ranks #35 of the 39 states and districts we publish, 15% 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 Washington?
Of the fixed home internet providers with at least 100 distinct connections in Washington, Comcast has the highest median real-world download speed at 223.0 Mbps, ahead of Astound Broadband at 188.4 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 Washington?
9 providers had enough tests in Washington to name: Astound Broadband, AT&T, CenturyLink, Comcast, Spectrum, Starlink, T-Mobile US, Verizon, Ziply Fiber. 5 of them carry a ranked median speed on this page: the rest are either a carrier's mobile network in Washington 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 Washington?
Tests run on phones and tablets, over home Wi-Fi or a cellular connection, are 30% of the Washington sample and median 103.0 Mbps. Tests run on desktops and laptops, which are almost always on a fixed line's Wi-Fi, median 135.1 Mbps. This is a device comparison, not a comparison of providers.
