Your realistic options in Butte 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.
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.
See T-Mobile Home Internet
Satellite
Starlink
Low-earth-orbit satellite. Latency is low enough for video calls and most gaming, unlike older satellite services.
- Best for
- Anywhere with a clear view of the sky and no wired option
- Watch out
- Hardware costs money up front, and heavy tree cover or a north-facing obstruction will cost you throughput
See Starlink
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.
Equipment
A better router
Rural connections are usually limited by the link, not the router, but a poor router wastes a good link and provider-supplied units are often poor.
- Best for
- Large or awkwardly shaped houses, metal roofs, outbuildings
- Watch out
- A new router will not add bandwidth you never had. Fix the link first, then the wifi.
