This model is a DOCSIS 2.0 unit, but a swap to a DOCSIS 3.0 unit would not be necessary for the new level of service- albeit, depending on other circumstance, it may help. Have you seen any change in speeds since your upgrade? What results are you seeing on a speedtest?
This is wrong. DOCSIS 3 modem is mandatory for this level of service. Yes I know DOCSIS 2 modem can provide this speed.--
