Cable is the backbone here. It reaches 94.6% of Dukes County, concentrated in the towns. Outside the cable footprint the picture changes sharply, which is why the address matters more than the county.
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 that means if you live here
The USDA classes Dukes County as a nonmetro county with an urban population of 5,000 to 20,000, not adjacent to a metro area (continuum code 7).

Only 301 locations, 1.9%, are recorded with nothing at 25/3 Mbps or better.
The most widely available technology here is cable, reaching 15,239 locations (94.6%); next is licensed fixed wireless at 21.7%.
Fiber reaches 541 locations, 3.4% of the county.
Cable reaches 94.6% of locations, more than fiber does, and it will be concentrated in the built-up parts of the county.
Filings come from 8 providers, of which 1 offer fiber and 3 licensed fixed wireless.
Served locations rose 0.33% year on year.
Fiber lags the rest of Massachusetts, where the median county is at 37.2%.
What people actually measure in Massachusetts
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.

Cellular networks, measured
The same measurement for the mobile networks behind 5G home internet. These tests come from phones as well as home gateways, so treat them as an indication of network health in the state rather than a home-internet plan speed.

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.

Your realistic options in Dukes County
Fiber
Fiber, if it has reached you
The best outcome by a distance: symmetric speed, low latency, no weather sensitivity, no data ceiling in practice.
Best for
Anyone whose address is inside a fiber build. Always check this first.
Watch out
Coverage stops abruptly at the edge of a build. Being a mile from fiber is the same as being fifty.
Fixed wireless
A local fixed-wireless provider
A regional operator beaming service from a tower or ridge to an antenna on your roof. In much of rural America this is the fastest thing available.
Best for
Counties where the FCC data shows large licensed fixed-wireless coverage, which this page tells you
Watch out
Needs line of sight. Quality varies enormously between operators; ask neighbours, not the sales page.
5G home internet
T-Mobile Home Internet
Home internet over T-Mobile’s cellular network. A gateway box you plug in yourself; no truck roll, no dish.
Best for
Rural addresses that still get a usable T-Mobile signal, often near a highway or a town
Watch out
Availability is decided address by address, not by town. Speed varies with how busy the local tower is.
