We cannot support Netgear CMD31T Docsis 3.0 cable modems on the Docsis 3.0 CMTS. This model netgear has experienced several issues since 2012 with Comcast, Cox, Time Warner and other Docsis 3.0 deployments as far back as 2012. The biggest issue with these modems is they will not bond downstream channels properly. This causes them to not be ale to register on the Docsis 3.0 network. This model modem will function properly on the Docsis 2.0 CMTS. Customer's with a CMD31T may rent or purchase a modem from us or purchase a new Docsis 3.0 modem through a retail store.
