EarthLink

Because it rides AT&T's lines, it's available at the same El Cajon addresses where AT&T has built fiber — so the real question is whether fiber has reached your street.

Internet in El Cajon — What You Need to Know
El Cajon Is Cox Territory
El Cajon's cable provider is Cox NOT Spectrum. Articles about Spectrum service in Southern California do not apply to El Cajon addresses. The practical wired internet decision in El Cajon is Cox cable vs AT&T Fiber where the latter is available.

El Cajon has one of California's most diverse communities for international family connections — particularly the substantial Chaldean Christian community with family in Iraq and the broader Middle East plus substantial Hispanic-American community with family in Mexico. For these households making regular international video calls fiber's symmetric upload speeds matter — Cox cable's 35 Mbps upload cap produces noticeably worse video quality on the receiving end of long-distance calls.
