Internet providers measured in Wisconsin, ranked by speed
Median real-world speeds for the 5 fixed home internet providers with at least 100 distinct connections in Wisconsin, 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 | TDS Telecom | 248.5 | 149.1 | 17 ms | 250+ |
| 2 | Spectrum | 208.2 | 24.3 | 28 ms | 2.5k+ |
| 3 | AT&T | 175.3 | 95.9 | 28 ms | 500+ |
| 4 | Airstream Communications | 97.2 | 74.6 | 27 ms | 100+ |
| 5 | Starlink | 21.2 | 12.6 | 32 ms | 100+ |
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 Wisconsin and named rather than ranked: T-Mobile US, Verizon. In Wisconsin 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.
Internet in Wisconsin: what the data shows
In Wisconsin, the median real-world download speed is 141.5 Mbps, 3% below the median published state of 145.6 Mbps, ranking #23 of the 39 states and districts with enough data to publish.
Wisconsin ranks only five providers, and TDS Telecom leads them at 248.5 Mbps.
Uploads median 25.0 Mbps and latency 31 ms.
Desktop and mobile tests run at about the same median speed, with mobile making up 32% of tests.
Across the 5 fixed providers with enough connections to rank here, medians run from 248.5 Mbps (TDS Telecom) down to 21.2 Mbps (Starlink), an 11.7× spread inside one state. Which network reaches an address matters more here than which state the address is in.
The Wisconsin sample carries enough tests to name 7 providers, 19 counties and 20 cities and localities. Chicago was its most-used test server, taking 70% of the tests among the five busiest.
Figures are medians of 5k+ 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 Wisconsin?
The median real-world download speed in Wisconsin is 141.5 Mbps, with 25.0 Mbps upload and 31 ms latency, measured from 5k+ browser-based speed tests on SpeedOf.Me.
Where does Wisconsin rank among US states?
Wisconsin ranks #23 of the 39 states and districts we publish, 3% 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 Wisconsin?
Of the fixed home internet providers with at least 100 distinct connections in Wisconsin, TDS Telecom has the highest median real-world download speed at 248.5 Mbps, ahead of Spectrum at 208.2 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 Wisconsin?
7 providers had enough tests in Wisconsin to name: Airstream Communications, AT&T, Spectrum, Starlink, T-Mobile US, TDS Telecom, Verizon. 5 of them carry a ranked median speed on this page: the rest are either a carrier's mobile network in Wisconsin 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 Wisconsin?
Tests run on phones and tablets, over home Wi-Fi or a cellular connection, are 32% of the Wisconsin sample and median 140.7 Mbps. Tests run on desktops and laptops, which are almost always on a fixed line's Wi-Fi, median 141.7 Mbps. This is a device comparison, not a comparison of providers.
