Netgear CM1000vsNetgear CM1100- How do they compare?

Design

Netgear’s CM1000 and CM1100 are quite similar in their exterior design. First, both modems come in a black deep color with a meshed plastic body. The mesh design ensures the modem does not overheat as the device continues to work all day. In addition, they both feature a tower design meaning, they are placed vertically rather than horizontally. Always consider this when you have limited space to work with. There is only one major difference when it comes to the physical design of these two: the number of gigabit ports. The CM1100 has two Ethernet ports. CM1000 has just one port.

Speed and performance

The speed is one of the most important factors to consider when buying a modem. Theoretically, the CM1000 and CM1100 provide speeds of up to 1 Gbps and 2 Gbps respectively. Netgear CM1100 takes the win here, and this is mainly due to the link aggregation feature that we’ll look at below. Speeds in a real world setup were found to be 200 Mbps and 350 Mbps respectively. But even with this difference, both modems are considered high speed and perform well for heavy users such as gamers.

Internet service provider compatibility

When you buy a cable modem, it acts as the bridge between the internet service provider’s signal and your router. The modems therefore have to be compatible with your service provider’s plan. Here, Netgear’s CM1100 performs better than its predecessor, the CM1000. And this is because, the CM1100 supports more cables from internet service providers. The CM1100 is compatible with the following: Comcast Xfinity, Cox, Mediacom Cable and others. On the other hand, CM1000 supports: Comcast Xfinity, Cox and Spectrum. The CM1100 is definitely a better choice because it offers more versatility. An important factor to note is that neither of these modems support fiber connections.

Ports and Link aggregation

Cable modems rely only on wired connections for communication. Because of this, they usually have at least one Ethernet port for connection. The CM1100 is a better choice as it features two modems compared to CM1000’s singular Ethernet port. Link aggregation on the other hand refers to the ability of modems to connect both Ethernet ports as a bundle to achieve higher speeds, usually up to 2 Gbps. The CM1000 does not support link aggregation as it only has one port. This feature however may not be important since there are very few internet service providers that support it.
