Rated 4 out of 5

So far so good. One minor glitch.

There was a small glitch the other night when I syncing the Ecobee smart thermostat. We lost internet and I had to reset the modem which was not fun to reconnect via Comcast. I had to reset it multiple times. Comcast even said they needed to send someone out to fix a problem that didn't exist. It just took a while to reconnect.

So far so good!

After a few days my nighthawk is working fine. Setup was easy and the wifi 6 provides a strong signal throughout the house including my garage. Very pleased so far

Best Router

I have used a lot of modem routers over the years and I gotta say this one, hands down, has them all beat. It's fast, efficient, and reliable and it makes connecting new devices a breeze. It also makes control over connected devices much easier. Solid 5/5 from me for the Netgear AX2700.

Ultimate Upgrade

I upgraded from an Arris and I couldn't be happier. Setup was fast and easy. The increase of speed was expected, but also noticed a huge difference overall in performance. I also LOVE the Nighthawk security app to monitor threats across all my devices. I no longer have any issues that I had with my previous modem router. I also have customization options I didn't have with my previous router. I wish I made the switch years ago.

Set up was very easy and the WiFi signal strength is excellent through three floors (including the basement). The iOS app was also very simple to use. Overall great investment!

Works great

I bought this to replace my Xfinity modem because of a weak WiFi signal. Setup was fairly easy. The only downside was I had to spend a half hour on the phone with Xfinity to have them disconnect their modem from my account. My WiFi is very strong and reaches the entire house now. I like that any device that connects to my WiFi is scanned for security. I will definitely recommend this modem to my friends and family. A little pricey, but worth it!

Easy to setup

I'm really happy with my purchase! The setup only took a few minutes with Xfinity on the phone and now I'm saving $15/month on rental fees. I like how it has a dedicated app and scanned every device I connected to the network. It was very easy to understand and very easy to set up.

NETGEAR is necessary gear!

The NETGEAR Nighthawk modem I purchased is working great! With two people working from home, it is imperative that the modem functions reliably. Set up was easy and fast. An added perk is I'm saving money from renting a modem.

Excellent modem/router

I purchased this modem/router for my granddaughter because the Xfinity version was not working well in her condo. The installation was simple and she had it up and running in no time. She was very happy with the performance, her Wi-Fi was now strong throughout her entire condo. She was so happy with how well it worked that I bought one as well. I can't say for other providers, but it works seamlessly with the Xfinity network. It was extremely easy to set up and using the Nighthawk app I was able to set up the name of my network, the password, and a guest network. I would recommend this modem router to anyone that has Xfinity as their ISP!

Back to Netgear after a disapointment with another brand, in which that brand disabled IPV6 protocol in using their app. Seamless integration with my cable provided after they had to 'rebuild' the connection. Happy to be back with Netgear.

Product and Support Staff questionable

My other NetGear cable modem worked fine, it was getting old and starting to fail. I am not well versed in computers and modems so I need someone who can break it down in simple terms. I'm having problems with this new one and when I get in touch with the help desk, I have a very hard time understanding the foreign speaking support staff. On the good side of things, they do get back to you if you request help and donj't close your ticket.
