Cable providers are regulated by the FCC, not locally. OP: Are you 100% fiber from the street, into your community and to your home? The blinding download speeds advertised by providers are at the ethernet ports on the modem (if so equipped). The WiFi speeds are maybe half or so the 'wired' speed on a good day, and are dependent on how many devices are active within your home. What speeds comes through the wire to the modem are also traffic volume dependent.
By way of example, we have Spectrum, who now touts download speeds "up to" 300 mbps. Haven't seen it yet, we've had 200 mbps service before the upgrade to 300, never saw better than 180-ish at an ethernet port on the router (checked once by a Spectrum tech). Our WiFi speeds (equipment is a Spectrum owned Modem/Router combo) are typically 112-150 mbps down, 8-12 mbps up. WiFi can indeed be glitchy, ours is frequently. However, Spectrum's marketing and disclaimers cover their butts quite thoroughly and the CSR's in their call centers are quick to recite them when you have an Internet problem and they remotely peer into your home setup and pronounce all is well. With Spectrum, their service (in many but not areas) is fiber to the street, coax into our apartment complex, and RG-59 coax (so last century, the complex is nearly 40 years old) into the individual apartments. Better than dialup, but the technology within the buildings will never allow for the full benefit of fiber technology.
