San Diego residential internet coverage
AT&T covers San Diego’s entire downtown area and suburbs, including La Jolla, Scripps Ranch, and Mission Bay. The only spots you likely won’t get AT&T coverage are the state parks and military bases.
Spectrum is primarily available on the northwest side of town, north of the Mission Valley Freeway. This area includes Silver Strand State Beach and Mira Mesa. Unfortunately, Spectrum doesn’t cover the downtown area, so you’ll have to look at AT&T or Cox if you live in that part of town.
Cox is available across most of San Diego but misses the coastal areas west of the Miramar Air Station. If you prefer cable to fiber, Cox makes a good alternative. Google Fiber is also available in select areas of San Diego, along with a handful of local providers, including Telscape.
If you live in areas where these providers don’t reach, HughesNet and Viasat offer satellite internet across the entire region. These satellite providers are a good option if you want an alternative to the landline providers, but they’re slower and cost more.
