ARRIS T25 vs. NETGEAR CM1150V – Which Cable Modem has an edge over the other?

Owning a cable modem would significantly reduce the costs that you would otherwise use to rent one from your Internet Service provider on a monthly basis. At the same time, the only way you can enjoy good service and make the most of your internet speed plan is when you pick out a high quality and resilient cable modem.

Generally, a cable modem is a network device that allows your Wi-Fi devices to communicate with your Internet Service Provider over a landline connection. It works by connecting a coaxial cable and an Ethernet cord from your cable modem to your existing router or wireless devices. What happens is that, once you have established the wired connection it converts an analog signal to a digital one so that it can grant access to broadband internet.

With that said, among the cable modems that are compatible with Comcast XFinity internet and voice services are the ARRIS T25 and the NETGEAR CM1150V. They are both Gigabit cable modems with almost similar performance levels however a great part of their differences is seen in their resilience and connectivity options. The table below highlights their features and outlines the differences between the ARRIS T25 and the NETGEAR CM1150V.

What are the difference between the ARRIS T25 and the NETGEAR CM1150V?                 

ARRIS T25 vs. NETGEAR CM1150V- How do they compare?
