A San Diego, CA Customer
AT&T Fiber
May 26, 2026 A San Diego, CA Customer
Spectrum Cable
March 17, 2023 While our speed is advertised at a minimum of 300 MB down, rarely do we see that speed. It throttles down quite often. Additionally, our service goes down frequently and always at the absolute worst times (I work at home). We pay $100 a month, which seems excessive but there are no other options for the speed we need. Everything else is slower and apparently there are no fiber options in our neighborhood that I can find. We live in a standard suburban area, so these options should be available.
