Seems good so far

Initially I bought this for gaming and does what it's supposed to do. Unfortunately what issues I seem to have are associated with my isp with slow upload speeds.

CAX80 Worth?

Nighthawk CAX80 is a great unit but probably only worth its cost if your internet provider can match its speed.

Easy to setup and works great

20-25 minute setup on xfinity, more than 6x my download speeds just from upgrading to this unit. Very excited to use it going forward, and the control center app is very helpful.

Great Quality

I was using the modem/router combo from my provider but there was to many blind spots and to much buffering. I upgraded to the NETGEAR Nighthawk Cable Modem WiFi 6 Router Combo (CAX80) and now I am not having issues. Would recommend this to everyone.

Easy 2-in-1

Netgear alerted me that I needed a new router and Xfinity also alerted me that I needed a new modem. The Netgear CAX80 was a perfect combo choice!

The integration of a multi?gigabit Ethernet port and link aggregation ensures ultra?fast wired connections, making it perfect for 4K streaming, online gaming, and heavy device usage

Good but didn't hold up long

Performed very well for three years but then services started failing incrementally (eg: USB sharedrive would only be stable for a day or two, requiring modem reboot to reappear). Then it seemed to struggle to handle all the devices on the network, intermittently dropping Internet access to a few. If it had functioned longer than it did I would give it a higher rating.

Difficult to set up

Difficult to set up. The instructions are terrible. I spent a long time on the phone with comcast to get it working. And now it doesn't work as well as our old one which is no longer supported. We have tons of issues with connectivity and speed.

Top Dog/ Solid device

This cable modem and Wi-Fi six router is very solid in terms of performance as it is more sensitive to proper cabling in inside and outside, so can help isolate potential cabling issues which once resolved this device is a top dog in terms of performance in seamless seamlessly covering 2500 ft.² of coverage with nearly identical bandwidth as the primary input.. works with all types of cable providers and I would highly recommend this.. is not much to program with it aside from unique SSIDs, and passwords and proper security.. It really is essentially plug-and-play as long as you have no cabling issues inside or to the facility?

New Nighthawk CAX80

Had to bite the bullet and buy a new router as my old one was starting to be unreliable. The Nighthawk setup was straightforward and required only about an hour to get the network operational. Getting all the optional features installed took another hour as there are quite a few. Discounting a few operator errors the process was almost painless. The increased speed and security measures are well worth the price. It's been up for a few days now and no issues. This is my second Nighthawk product?.Great value for the money.

Upgraded Router Modem

We hadn't upgraded our equipment in a very long time. After reviewing other users feedback, we chose this particular choice. It was a bit lengthy to install but with the help of Comcast, all is working smoothly. I would definitely recommend.

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...
