Netgear NightHawk C7100V Review (Buying Guide)

Netgear NightHawk C7100V Review (Buying Guide)

The recent Netgear Nighthawk C7800 we reviewed here has us left a good impression. It is a 2-in-1 modem + router product, offers lots of features, and ultra-fast, thanks to DOCSIS 3.1 technology and a fast processor. However, the biggest constraint with it is the price which is a little on the higher side (compared to some of its competition). 

Fortunately, Netgear has a lot of products that cater to different markets. If your internet subscription can’t go beyond 300Mbps, then there’s no reason to spend luxury on DOCSIS 3.1 modem or router. This means, DOCSIS 3.0, while old, is still a viable option.

Now, if you’re into the 3-in-1 device, but don’t want to spend a lot of money, then Netgear’s Nighthawk C7100V will offer just like that. It still uses DOCSIS 3.0, and so it is cheap and can save you even more money because it combines both modem and router into one product.

To know more about the product, read our Netgear C7100V review below.

Netgear Nighthawk C7100V Features

If you can’t spend 400 bucks for a modem router combo, then the Netgear Nighthawk C7100V is a good option. It is cheap, and while older, packs a lot of features that will still be able to compete for even the most recent budget combo modem + router devices in the market. Being an upgrade from the Netgear C7000, the Netgear Nighthawk C7100V features Voice services (as with the “V” moniker), as well as Xfinity internet. It is also available without a contract. 

 1. High-speed Internet, AC1900, Dual-band Wi-Fi

The Netgear C7100V supports up to 1900Mbps download speed similar to its competitor Motorola MT7711. It features both 2.4GHz Wi-Fi, and 5Ghz Wi-Fi. The 2.4GHz Wi-Fi can go as much as 600Mbps, while the 5GHz can go as much as 1300Mbps, totaling throughput at 1900Mbps (AC1900). 

If you wonder what the difference between the two bands, read the bullets below:

  • 2.4GHz can cover a larger area but is slower than 5GHz
  • 5GHz is faster than the 2.4GHz but has less coverage area

As for area coverage, more of that below. 

2. 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. 

3. 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.

The Netgear C7100V, on the other hand, features DOCSIS 3.0, with 24×8 channel bonding. That means, 24 downstream and 8 upstream channels. When the Internet service provider (ISP) limits your data speed, the cable modem router with channel bonding technology can combine all these limited speeds from 24 of its downstream channels, and 8 of its upstream channel, to create a fast download and upload speed. 

Though this can also be considered as a drawback because other models like the Netgear Nighthawk C7800 and Arris Surfboard SBG8300 has the latest DOCSIS 3.1 that can handle 32 downstream and 8 upstream channels. But as we said earlier, If your internet subscription is below 300Mbps, then there’s no reason to purchase a DOCSIS 3.1 router-modem combo.

4. Telephone jacks

As you can tell from its “V” moniker, the Netgear Nighthawk C7100V is compatible with Comcast Voice service. It has two integrated telephone jacks which will enable you to utilize all Comcast Voice service features. You can also use the caller ID, 3-way conference calling, Call Waiting, and call forwarding among many other features. 

5. Beamforming+ technology

The beamforming technology can extend your Wi-Fi coverage, reduce dead spots, unnecessary radio frequency interference, and deliver a more stable Wi-Fi connection for voice and HD video.

Netgear improves this technology by implementing the beamforming standard with a fine-tuned Wi-Fi design to further improve the Wi-Fi range and performance across all Wi-Fi devices, most especially to the 5GHz band, which as we said, is faster than 2.4GHz but has less coverage area.

6. More ports

The Netgear Nighthawk C7100V offers even more ports than the more expensive Netgear Nighthawk C7800. It has 4 Ethernet ports and 2 USB ports, allowing you to run several devices simultaneously. You can directly connect your computer, printer, gaming device, storage drive, and other devices in the cable modem router with ease. 

7. 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. 


The Netgear C7100V is one of the best combo available in the market today. It is cheaper than others but has features that are more than good enough for the money. Yes, it is only built on DOCSIS 3.0, but unless you are planning a Gigabit speed upgrade in the future, this modem router should be fine. 

The 1.6GHz Broadcom BCM3384Z processor has always been commended for its reliability. And it shows in this product. It is fast and stable. That, of course, still depends on your Internet service provider. However, its limited compatibility may not work for your existing plans. If you’re currently not on Comcast, this modem router combo will not work for you. 

I also would like to mention that the device doesn’t have a fan. So sometimes it can heat up pretty quickly. And if it does, it overheats and shut down. But this also depends on your place. So some may experience it, and some may not experience it at all.

Regardless, we think the Netgear C7100V is a good buy for Comcast users. It is cheaper than others, has many ports available, and Netgear also sells battery packs for this system. It may not be as good as Netgear CM1000, but it is good enough combo for the most part.
