Grant County is genuinely hard to serve. 14.7% of locations here have no fixed broadband at all, so for a lot of addresses the real choice is satellite or a cellular home-internet gateway, not a wired provider.
Everything below comes from the FCC's Broadband Data Collection, the filings providers are legally required to make about where they offer service. It describes the county; your own address can differ, and that is exactly why the technology mix matters.

What people actually measure in Wisconsin
Median of real speed tests run on each network during 2024, from M-Lab. This is measured performance, not an advertised plan speed, and not a customer review. The middle-half column shows how consistent a network is: a wide spread means your experience depends heavily on where and when.

Latency is the number that decides whether video calls and gaming feel right, and it is where satellite differs most from everything else. Measured data is statewide: below county level there are usually too few tests to report an honest number.
