Great, Fast, Reliable

Picked this up to replace my ISP provided modem/router. It has outperformed what I had before in every aspect.

CAX80 review

So far, so good. Once I figured out the initial setup protocol, the rest was quite easy. Our internet provider (Spectrum) had no trouble identifying modem. Was initially worried about going from discreet components (router

Worked great for a few years

W head this for 2-3 years and it worked well at first, but then would connect/disconnect every few seconds for a couple of days anytime it was rebooted.

New model

The AX6000 may be a newer model but there's no noticeable difference from the older model I had. I only replaced because Netgear was no longer going to offer updates or other services for the older model.

Worked great for 6 months and died

CAX80 was sold by Netgear at a 20% discount after it announced the previous version would not be supported. After 6 months of use, it died along with TV, internet, and security systems for days. The fix was through Netgear customer service which downloaded a revised program requiring all my systems to be rebooted and reconfigured. This defective product should not have been released until all the bugs were worked out. Will consider the next purchase from a competitor.

Not an upgrade

This unit is not better than the one I had been using for the past 6 years. It actually takes longer for apps to load on my televisions and it drops the wifi signal at times. I only purchased it because Netgear said my older one was outdated and updates would no longer be available. What's the point of discontinuing a product if the newer version isn't any better.

Best Upgrade

It was time to upgrade my equipment and the Nighthawk CAX80 was the choice based on research of other top brands. The CAX80 delivers the speed, easy set up, quality as advertised. I am very pleased with the upgrade and reliability.

Nighthawk CAX80

Love my Netgear Nighthawk. This is the second combo unit (modem/router) that I've had, and they last! The only reason I upgraded is because my old one wouldn't support the faster network speeds. I also, with my old modem/router, had to get a Nighthawk Extender because I have a large house (5500sqft). With this new Nighthawk CAX80, it completely covers my whole house! I'm very happy!

CAX80 router

Very good router consistent speeds. Armor security is good but expensive annually. Some issues with upload speeds when wired to xbox ( could be xbox speed test issue tho). Cat6 cable is deffinitly required and as short as possible. I run two consoles on mine. Wifi for devices is seamless.

Set Up Required Lengthy Call to Customer Service

Set up required a call to customer service. Using the chat bot for questions turned out to be too complicated, kept getting cut off. Customer service guy was excellent and patient, and made sure that everything I wanted to set up and all devices worked before hanging up. I explained my issues with chatbot and he listened. This was a different experience than my previous Netgear Orbi system with satellite. It had better range, easier set up for some reason. No call needed. However the device died within the warranty period, I got a new one under warranty and that died too about 2 years later. So I tried this Nighthawk instead. The range is less distance, so I bought an EAX17 range extender to go along with it and that worked well and was reasonable set up. With my Orbi system I had ordered a year of the Armor protection, but it isn't straightforward how to transfer that to my new Netgear device. So I will likely need to call customer service again, or try my luck with the chatbot since it seems like a straightforward question.

New life for seven year old iPad.

The new router plus the included one year subscription to Netgear Armor have improved the download speed and blocked a lot of pop-up ads, banners and animated widgets.

Insane Speeds!

I have used Motorola all my life, and the only thing I regret about this modem is not buying it sooner. I have a 3,000 square foot home with tons of devices connected to the WiFi and wired in, 4 total Netgear switch boards, full home security cameras, plus 6 family members ALL WIRELESS and absolutely flawless! I have Spectrum Gigabit tier, and I am impressed. Even the best Motorola combination modem and router did not reach my furthest bedroom very well. This is not even a remote problem with the wifi reach that this modem has. Installation was also super easy.

Return

Two things, one it was cheaper at best buy, and two it would not hold the signal and kept dropping, so I had to return it.

With some help from a Netgear tech the installation went smoothly. I'm 76 and not very tech savvy. He was polite, patient and professional. Many thanks!

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...
