My Netgear C7100V modem recently mysteriously reset to factory settings at the same time Xfinity was doing some system maintenance. None of my devices or computers could use the internet.
Netgear technical support said that Xfinity must have reset it and that they could reset it.
I purchased this modem. It's not Xfinity equipment. But it is advertised as Xfinity approved and compatible.
Can they do that to a modem they don't own? Are there standard protocols in place that give them access?
