Fiber optic internet delivers the fastest and most reliable performance available. With symmetric speeds up to 5 Gbps in some areas, fiber is ideal for power users, remote workers, and households with heavy streaming needs.

Cable internet remains the most widely available high-speed option. Using existing coaxial cable infrastructure, services from providers like AT&T offer speeds ranging from 100 Mbps to 1.2 Gbps. Upload speeds are typically lower than download, which may affect video conferencing and cloud backup performance.

DSL connections use telephone lines and offer modest speeds of 10-100 Mbps. While slower than cable or fiber, DSL is available in many underserved parts of Wisconsin where other technologies haven't yet reached.
Satellite internet from providers like Starlink or HughesNet serves as a last resort for rural areas outside Janesville proper where no wired or wireless broadband reaches. Latency is higher, but newer low-earth-orbit satellites have significantly improved performance compared to traditional geostationary services.
