Fastest Internet Providers in Antioch, California

Xfinity follows closely with their DOCSIS 4.0 upgraded cable internet, providing download speeds up to 2 Gbps in select areas as of 2026.

In 2026, the pursuit of higher internet speeds in Antioch is being led by AT&T’s continued deployment of its fiber-to-the-home network. The company’s multi-year expansion project, which intensified in 2024 and 2025, is projected to make multi-gigabit fiber speeds of 1 Gbps, 2 Gbps, and even 5 Gbps available to over 55% of Antioch by the end of 2026. This aggressive fiber build is directly supported by the anticipated completion of state and federal broadband infrastructure grants, aiming to bridge the digital divide.

Xfinity is also enhancing its network capabilities by upgrading its cable infrastructure to DOCSIS 4.0.
