CAX80

Best modem to date. Eliminates rental fees from local provider. There is no need for wifi extender because built in router sends singal through whole home. Also, great parental controls on app.

Modem is GREAT, WIFI... Hmmm

Note: I am doing merging the 2.5 and 5G networks, maybe that could improve speed, but with everything else the same, and just swapping out the Internet Supplier Modem with this one, it is super fast through the direct ports, and saves money from renting from the provider... However I am going to use another product for WIFI, since this one all the TV's are blotchy, and the speeds are not good. I even changed the channels to non-conflicting with other neighbors, so not sure what's going on, but will just try another wifi router.

Superior Range

Our old router struggled to provide WiFi to a video baby monitor on the other side of the house. The coverage and quality is perfect after setting up our new CAX80. Would recommend to a friend.

Awesome router

My internet was not able to keep up with the demand of multiple gaming devices, streaming and working from home, so we upgraded our internet to 2 GB and as a result had to upgrade our router. My office is above the garage, so we chose this for its range and to future proof our internet for when we inevitably have even more devices online. This router is so powerful we were able to stop using all 5 of our wifi extender, and the security features are also great. I like that I can see all devices connected to my internet and can block devices accordingly. Its quite futuristic looking, and very easy set up. Its a bit pricey, but worth it in my mind to have a router that will be able to handle 4 GB if/when we need to upgrade our internet yet again and to be able to use the internet around our entire home and garage without any extenders. Very happy with this purchase!

Installation was fairly simple overall. No hiccups. Kinda weird and bulky shape compared to other units I've seen but has worked well since installed.

Just What I Needed

The Nighthawk CAX80/AX6000 is a perfect fit for my 2400 square foot home. The performance has been very good and more importantly, very stable. We only use about 12 devices (laptops, phones, cameras and other smart devices). We increased our internet plan, so we needed an upgrade. The Nighthawk CAX80 allowed us to maximize our gigabit performance. Installation and setup was very simple with the ISP provider and the setup was simplified with the Nighthawk app. There are still a number of options that we could implement if needed. I would recommend this modem/router comber for medium size homes.

Easy installation for this fast device

I purchased this modem router directly from Netgear and received it two days later. I have never installed a modem but I have a little tech knowledge. The installation instructions were detailed and easy to follow. Installation took about 30 minutes. The modem/router easily connected to my devices (about 15 devices including lights, phones, tablets and tv's). My download speed is 10 times faster than the 10 year old modem it replaced. The download is instant on most websites. I would recommend the combo modem/router.

Blazing?Fast, Reliable All?in?One Modem/Router

After upgrading to the NETGEAR Nighthawk CAX80, my home network became noticeably faster and more stable across all devices, especially when streaming 4K content and handling multiple video calls at the same time. The built?in DOCSIS 3.1 modem and WiFi 6 support mean I can fully use my high?speed internet plan without paying monthly rental fees to my provider. Setup with the Nighthawk app was straightforward, and once activated the connection has been consistently strong in every room, eliminating dead spots I had with my old gateway. The four Gigabit Ethernet ports plus the 2.5 Gbps multi?gig port give me plenty of options for hard?wiring my office equipment for maximum speed and low latency. Overall, this modem/router combo delivers the performance and coverage I was looking for, and it feels like a future?proof investment for faster plans down the road. I would definitely recommend the CAX80 to anyone who wants a powerful all?in?one device instead of juggling a separate modem and router.

Netgear Nighthawk

Very easy installation. Installed through my spectrum app. It is putting coverage in my home where it was weak before. I tried another brand but I will never use anything but Netgear products. This is my 3rd one in 22 years and I have only upgraded to a newer model each time.

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...
