Overall Assessment

The Netgear CM1000 is the ideal cable modem for residential settings with multiple bandwidth-hogging devices. The unit’s modern, sleek design ensures compatibility with most home décor designs. The maximum speed is about 10,000 Mbps depending on your cable, Internet package. This not a Wi-Fi router combo unit, just a cable modem. So, you will need an additional wireless router for a Wi-Fi signal.

To get the most out of the CM1000, you will need a top-tier (300 Mbps or higher) Internet package. If you do not have this in place at the time of installation, the cable modem will not perform to its maximum potential. A major misconception that gets a lot of customers is thinking their Internet package has no impact on a cable modem’s functionality. The two work together like a horse and carriage, you cannot have one without the other.
