Those households also have one poorly configured Wi-Fi access point, which is jockeying for airtime with dozens of competing access points in the same frequency range, meaning the customer is realistically going to see maybe 200Mbps aggregated across those devices (due to interference, channel congestion, that one streaming device with a -90dBm signal sucking up all the airtime at the lowest supported data rate...)

IMHO we need to address the "last meter" experience before mandated gigabit internet speeds mean anything.
