San Diego residential internet coverage
San Diego’s a big place, but AT&T manages to cover the 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 service is available mostly on the northwest side of town, north of the Mission Valley Freeway. This 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.
And if none of these providers meet your needs, HughesNet and Viasat offer satellite internet across the entire area (and nationwide). These satellite providers are a good option if they’re your only option, but you should go with a landline connection if it’s available to you.
