Netgear Nighthawk C7100V Cable Modem 2020 Latest Updated Review

Netgear Nighthawk C7100V Cable Modem 2020 Latest Updated Review

The Netgear c7100v has a very fast and reliable internet speed of up to 1300 megabytes per second. This means that it is possible for you to download a whole HD movie in 15 seconds, supposing the movie has a size of 2GB.

This cable modem router gives you high-speed Internet connection with combined speeds of up to 1.9Gbps† with AC1900 WiFi. Supports two XFINITY Voice telephone lines with battery backup.

Enhanced features include 3-way conference calling, caller ID, call forwarding and more. Save up to $168 a year* by eliminating Internet service provider rental fees.

Ideal for XFINITY Internet and Voice service.

Top broadband speed

If there’s something the long-winded name doesn’t already include, that’d be the fact that the new Nighthawk C7100V’s built-in cable modem is super-fast.

Netgear says supporting DOCSIS 3.0 with 24×8 channel bonding (24 downstream and 8 upstream,) it can deliver a broadband download speed of up to 960 megabits per second.

While this is likely faster than what you’re paying for right now, it means the gateway is ready for the future when you want to get faster broadband speed from Comcast.

The C7100V also includes two integrated telephone lines that support all features of Comcast phone service, including 3-way calling, caller ID, call forwarding and others.

Reliable Wi-Fi

As a Wi-Fi router, the C7100V is the enhanced version of the NightHawk R7000, which is one of the best routers from Netgear.

The gateway can deliver the top Wi-Fi speed of up to 1300 megabits per second on the 5GHz band and up to 600Mbps on the 2.4GHz band, simultaneously, with beam-forming, which helps ensure reliable connections with clients.

The gateway also include a backup battery option (battery sold separately) that allows it to work for up to 8 hours of standby and up to 5 hours of talk time during power outage.


  • Cheaper than other options
  • Easy to install, setup can also be activated through Comcast’s web interface
  • Faster and reliable connection, thanks to a 1.6GHz Broadcom BCM3384Z processor
  • It is a 3-in-1 device: it is a modem router combo with Xfinity voice.
  • It is fitted with 5dBi antennas for maximum coverage
  • Optional battery pack
  • Has more ports


  • Only DOCSIS 3.0, not a future-proof investment
  • Select compatibility
  • Doesn’t have a fan, so it heats up really quickly

DOCSIS 3.0, with Channel Bonding Technology

DOCSIS 3.0, with Channel Bonding Technology

As mentioned above, the Netgear Nighthawk C7100V is built on DOCSIS 3.0 technology.

That means, the device will be able to cover up to 1800 sq. ft., and connect up to 30 devices at the same time. Since it is an AC1900, the speed can also reach up to 1900Mbps.

The AC1900 offers channel bonding technology. It helps you maintain your internet speed even during peak hours

Basically, when your Internet service provider (ISP) detects an overwhelming amount of network traffic, it limits the internet speed for its channels.

What channel bonding does is combine all the available speed on each channel to maintain the original Internet speed subscription.

 24×8 Channel Bonding

As mentioned, channel bonding combines all the available speed on each channel to maintain the original Internet speed subscription during peak hours.

On older DOCSIS 2.0, multiple channels are not available. There is only a single channel, which means it is 1×1.

So when the internet service provider (ISP) limits the data speed on each channel during the peak hours, the limited speed is the only speed the DOCSIS 2.O modem will get.


Netgear says the Nighthawk C7100V is easy to setup and can be activated with Comcast via its web interface without a service call.

The new gateway is slated to be available later this year with the suggested price of $300.

Optional Backup Battery

Optional Backup Battery

Just like any other cable modem router device, the Netgear C7100V doesn’t have a battery.

This is because the VoIP system consumes more power. So when there is like an electrical outage, your cable modem router will also be inactive.

Thankfully, Netgear sells a separate backup battery for the Nighthawk C7100V system.

The battery pack will be able to support devices for up to 5 hours when on call and up to 8 hours if in standby mode.
