Max speed by "regulation or law" is 54 K[something] Buy a 56.6 modem and you are not allowed to go beyond 54 [whatever]. Crappy law/regulation for the Telecom industry.
Thank goodness that I have cable-modem broadband download speeds of up to 10 to 15 MB/s [advertised], but most sites, and a problem with the too-cluttered broadband service node [their tech/repair guy tells me] usually gives me a 1.5 to 2.0 MB/s download speed. They advertise I can go up-to 50MB/s, but they would have 10 times the number of digital cable/phone/net users on this service area node than should be [2000 instead of 200] and there is no money to fix that. My building itself has 200+ apartments, so it/we should be a single service area node by itself/ourself, but no money to upgrade the service lines, the repair people keep telling me.
