The NETGEAR CM400 High Speed Cable Modem provides a connection to high-speed cable Internet, up to 340 Mbps. With DOCSIS 3.0 it is 8X faster than 2.0. It is CableLabs DOCSIS 3.0 Certified to work with cable Internet providers XFINITY from Comcast, Spectrum, Cox, Cablevision and more.
My initial purchase of this modem lasted 3 weeks, then it stopped working. Replaced with same model and would not work at all. TWC lead technician said they had problems with this modem not working. Switched to a different mfr and have not had any issues.
