Fastest Internet Providers in San Jose, CA

Sonic is the fastest provider in San Jose, with speeds up to 10 Gbps.

The fastest internet providers in San Jose are Sonic, AT&T Fiber and Xfinity. Sonic is the fastest, offering speeds that surpass AT&T Fiber on a fiber network. Sonic is unmatched in the region when it comes to speed, but it serves only a small fraction of the city. Sonic doesn’t use tiered internet plans, though, so if you can get it in your neighborhood, you’ll be able to tap directly into that blazing-fast fiber connection.

AT&T Fiber is the second-fastest internet option in San Jose, with speeds up to 5 Gbps. Thanks to fiber-optic technology, AT&T provides symmetrical download and upload speeds, which traditional fixed wireless and cable connections can’t achieve. AT&T Fiber even offers its AT&T Extender Wi-Fi Coverage Service and AT&T Active Armor technology when you purchase multi-gigabit internet in San Jose. For an added bonus, you can subscribe to AT&T HomeTech Protection to cover all your home electronics.

It’s not as fast as Sonic or AT&T Fiber, but Xfinity is a suitable alternative with speeds up to 1 Gbps. Cable connections have low latency and larger infrastructure, making them reliable and widely accessible, which is why Xfinity is the best choice for fast cable internet. Xfinity offers upload speeds only up to 35 Mbps, so it could come up short for content creators, gamers, or heavy streamers.

Internet Availability in San Jose, CA

AT&T Fiber, Xfinity and Sonic offer San Jose residents a few high-speed, wired internet connections. These providers are available in various parts of the city, but there are some areas where you may not be able to get access. The providers that are available to you will depend on your neighborhood, so let’s take a closer look at the areas that AT&T, Xfinity and Sonic cover.

AT&T Fiber covers 37.1% of San Jose, with availability concentrated near the city center and spottier coverage in suburbs to the north and south. So, if you live in Luna Park, Japantown, Willow Glen, or Washington, you’ll most likely be able to choose AT&T Fiber as your internet provider. However, don’t count on getting coverage if you live in Windmill Springs or Berryessa.

Xfinity offers high-speed cable internet service in San Jose. It’s almost everywhere in the city, covering 98.4% of the city. There are a few spots where you can’t get Xfinity in Tasman and Zanker, around San Jose State University and parts of Santa Teresa Boulevard in southern San Jose.

Sonic serves 6.4% of the city, which isn’t as noticeable as AT&T Fiber; however, if you’re in the city center, chances are you’ll have access to its service. From the Hensley Historic District to the edges of Little Portugal, you’re covered by Sonic. One area it doesn’t cover is McKinley Elementary School and the neighborhoods west of it, right by the Northside Theatre Company.
