I have a Docsis 3.1 modem from Netgear (CM1000) . Is there a way to search if my address allows for self-install? I've called in and get different answers... The first person I spoke with said no, the second person said that my account should already be at gigabit speeds (which is not) and that no other install is requried. It seems as if the call center doesn't know what the service is. Just need a defiante answer so I can upgrade if it's avialable in my area.
