Netgear Nighthawk C6900 Review

This modem cum router delivers extremely fast and reliable speeds, making it a favorite among home users. So, what makes it so good, and should you go on and get it?

When I first thought about replacing my rented modem with a high speed device of my own, it never occurred to me that I could replace it with a gateway device that does the work of both a modem and router. After a lengthy chat with a kindly attendant, she pointed out that the Netgear Nighthawk C6900 made an exceptional device, especially where speed and range are concerned. I brought it home with me, and let’s just say it has been one of my best acquisitions.

Netgear Nighthawk C6900 Breakdown and Review

  • EXTREMELY FAST WiFi—Up to 1.9 Gpbs combined WiFi speed for extreme gaming and streaming
  • 1.6GHz combined processor speed boosts performance for streaming & gaming

If you have used Netgear devices before, you can attest to the fact they are extremely reliable, versatile and practical. The Netgear Nighthawk C6900 lives up to this character, delivering impressive speeds and proving easy to use whenever you need it.

This device’s fast internet transmission speeds are largely attributed to its DOCSIS 3.0 compliance. This standard is one of the fastest currently, providing speeds that are almost eight times faster than the previous DOCSIS 2.0 technology. As an added feature, the Netgear Nighthawk C6900 supports channel bonding, delivering a 24 x 8 channel bonding configuration. This results in 24 downstream channels and 8 upstream channels which bear the capacity to provide you with download speeds that reach an impressive 960Mbps and up to 131Mbps upload speeds.

As a Wi-Fi router, it operates on the 802.11ac standard and delivers up to 1,900Mbps speeds. You will be glad to know that the Netgear Nighthawk C6900 is compatible with all Internet Service Providers including Cox, Comcast, Xfinity and others. However, it does not bear the capacity to support voice bundle services such as AT&T, Verizon and other voice service providers.

On top of acting as your router and modem, this gadget saves you a substantial amount of money. Modems from internet service providers come at a cost, and the truth is, they are nowhere near half as fast as the Netgear Nighthawk C6900. When you get one of your own, you save up on money, close to $120 every year, that would otherwise have ended up with your service provider.
