Rated 5 out of 5

Fast, Reliable, Easy Setup

've been using the NETGEAR Nighthawk CAX80 for a little while now, and I'm genuinely impressed with how well it performs. Setup took only a few minutes - just plug it in, activate with my ISP, and WiFi was up and running. The speed and coverage are the biggest highlights. I get strong WiFi in every room, even in areas where my old router struggled. Streaming, video calls, and gaming are all smooth with no noticeable lag. It handles multiple devices at once without slowing down. I also appreciate that it combines a modem and WiFi 6 router into one device - less clutter and fewer cables. So far, the connection has been stable and consistent. Overall, it's a great upgrade and has made my home internet much faster and more reliable.

SECURE BUT SLOWER

I find the new unit secure, but operating slower than my previous dual channel modem. I am averaging about 200mbps less download speed and 20mbps upload speed. Security at the expense of a little speed?

Best decision

Best decision I made was purchasing my new Netgear Nighthawk. What a huge different it made in my internet speed. We went from 120mbs to over 400mbs. It's insane how quick and easy it was to setup and connect to all 25 of my devices. Netgears support team is amazing also. They helped me register my new modem and ensured that everything was working flawlessly before ending our call. Amazing customer service and amazing equipment. Couldn't be happier with my purchase.

Great modem, easy setup. I did a pretty thorough search and this model seems to be at the top. So far, it's been great. I use it as a modem only(bridge mode) in conjunction with my Google Nest mesh system.

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.

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...
