What customers say about "Key Specs"
NETGEAR N600 (C3700) DOCSIS 3.0 WiFi Cable Modem Router
  • This definitely uped my WiFi speed. There hasn't been any lag since I started using it. We have 3 playstations, 2 smart tvs, 2 laptops and 5 smarts using going at once.
  • We are able to connect multiple devices to the internet wirelessly and not have reduced speeds.
  • Haven't had a dropped connection from any wireless device yet. The speed of the wireless connection is great.
  • The Internet is very high speed and there is good connection to all of my devices.
  • Works fine EXCEPT wifi speed is not good for over 30mbs on Comcast, I pay for 200mbs and wired is better but still has a Max of only about 120mbs, has the latest firmware but that makes no difference.
  • Cable speed is as fast as the modem I was renting from Comcast but the range sucks.
NETGEAR AC1900 Nighthawk Wi-Fi DOCSIS 3.0 Cable Modem Router
  • Right out of the box the performance with this Nighthawk Modem is amazing I’m reaching the max that my connection is allowed in my area until I upgrade my package at a later time but right now I’m on the Blast 93Mbps/12Mbps speeds.
  • Has increased my home network speed significantly. No more speed issues.
  • Great speed and reliability. Also has great distance, am able to stay connected even when at the pool of my apartment
  • So much better than the regular come cast modem ! I have three nest cameras and a lot a lot of devices hooked up and speed is awesome !!
  • It works fine, but I keep loosing downstream channels from 16 down to 8, usually lossing channels 1-8. This is extremely annoying because it causes my download speeds to drop, no significantly, but enough to be an annoyance.
  • Wi-Fi performance is routinely bad, even for devices near the router. Wired connections work great though (hence the two stars)

NETGEAR AC1900 Nighthawk Wi-Fi DOCSIS 3.0 Cable Modem Router
  • 24x8 Channel Bonding that’s 24 Downstream channels and 8 Upstream channels allowing for a better connection. This means I’ll enjoy full connection with the Comcast Servers while at high peak usage hours in my town when everyone is connected.
  • The combo modem and WiFi is easy to connect and very fast.
  • Crazy Wi-Fi range (even connect in backyard)
  • Never had to restart/reset router (unless service interruption occurs by ISP)
  • Using an external router with the AC1900 could complicate setup due to the unit already having a built-in WiFi antenna
  • The app is confusing. I haven't looked closely but it wasn't intuitive and I haven't set a custom network name/password yet.
