A WFH Internet Machine!

With multiple people taking zoom calls, multiple WiFi connected speakers, and devices in the house, this Modem/Router significantly brought up our overall speed and can handle the 15 devices all attached to the internet. Super impressed by the easy setup and this Modem/Router can do it all!

NETGEAR Nighthawk Vable Modem

What a difference a cable modem upgrade makes! I am now able to take full advantage of my broadband speed without having to rent a router from Xfinity! It pays for itself!

Happy to have upgraded to the CAX80

Prior to installation, downloaded the firehawk app. When the cax80 arrived, in very short time I had connected all of my systems with no issues. After my cable provider updated to the new Mac address, everything worked as designed. I did install the eax15 extender to ensure the wifi extended across my property. All in all.. very satisfied with speed and range.

Installation nightmare

Once I got the modem/router installed it has been fine. But installing it was a nightmare. The instrux said to use the app. I spent over three hours with their support. He said that the app doesn't work with that model. He gave me a URL and then we breezed through it (after three and a half hours)

Worth the upgrade

Due to an Xfinity upgrade in data speed, my wife's work laptop was timing out of a program she uses. I upgraded our router modem from CAX30 to CAX80. The swap out took about 40 minutes. NETGEAR has made installation with Xfinity service easier than ever. I wouldn't hesitate to recommend purchasing any NETGEAR equipment for the quality and customer service.

A great upgrade

We recently upgraded from an Arris Surfboard that kept dropping the 2.4Ghz signal. So far it's been great! I'm running around 1500 megahertz and it does a great job handling it.

excellent modem

After years of paying monthly rental fees for a modem from my internet provider, I finally decided to make the switch and buy my own. After a lot of research, I landed on a Netgear modem-and honestly, I wish I had done it sooner Love it

Unstable, frequent drops, difficult setup

I regret buying this modem. My old Motorola was more reliable. None of my devices automatically reconect to wifi if i lose power, i have to activate the modem through the app every time. So if i lose power while im away, none of my security cameras will have internet until i return home and setup the modem again... not to mention all the internet traffic from the firmware alone. Never again Netgear.

set up was a nightmare

Now that the router combo is finally set up it works fine. The instrux said to use the Netgear app for set up. After three hours on the phone, the support rep said that the app is not compatible with this product. He sent me to a website. The set up worked fine from there.

Great combo device

By Plemans

This device is a great example of what a combo device should be. There's tons of features you can read about in the above but the one feature that I appreciate the best is the fact that the firmware for the modem is now separate from the router portion. Meaning your router portion can now get updates independent of the modem. This is critical as its one of the major con's of combo devices. In terms of speeds, it routinely pulls 1.1-1.2gig from my xfinity service. I then use it to feed my orb...

A Fantastic New-Generation Router/Modem!

By rhnh

I set up my CAX80 a week ago, bought through Amazon where it's now available. My ISP is COX and this unit takes full advantage of the their gigablast plan (I'm getting 940Ghz Ethernet/500+Ghz on 5GWifi separated by 3 rooms). It is capable of far greater speeds, but I'd have to wait for future COX plan upgrades. Installation was simple and straightforward. One reason I decided to get the CAX80 is that Netgear provides router firmware updates for this newest model of router/modem. This is sepa...
