A:AnswerYes, our service provider is Suddenlink and we were able to connect. You just need to call them and let them know. I believe they have to get info from Netgear machine and you’ll be good to go.
A:AnswerUnfortunately I can't answer your question about using this cable modem/router with regard to fiber optics connection. We have regular cable internet service. I can tell you the technician recommended getting this Netgear unit over what the cable company provides. It gives the best spectrum of signal available for the cable company.
