Customer Ratings & Reviews

Had some initial setup issues that took some NETGEAR suppor to correct. Has been working pretty good since.

Ive had nothing but an easy time with this modem. i would recommend it to anyone on comcast.

I am a customer of Comcast Xfinity. I recently upgraded to the Extreme Pro 1200 plan. I had a Netgear C7000 modem I purchased years ago, which worked great for connections below 1gbps because that modem supported DOCSIS 3.0. I purchased the Netgear CAX80-100NAS for two reasons, I needed a DOCSIS 3.1 cable modem, and I wanted Wi-Fi 6 connectivity to compliment my Extreme Pro 1200 plan for my capable wireless devices. Xfinity removed my previous C7000 modem and added my CAX80 to my account. This process took less than fifteen minutes. I was up and running. I immediately went to multiple sites testing to ensure I am getting up to advertised speeds of 1.2gbps. After many short tests, I confirmed that Xfinity and the CAX80 exceeded my 1200mbps. Great. The trouble began when I began to play some multiplayer games online. My connection would seize up and continue or just cutoff completely. The disconnection occurs while my CAT6 cable is connected in to the 2.5GbE port on the CAX80 linked to the Realtek 2.5GbE Ethernet port on my PC. This does not occur while plugged in to the Intel i211 1gbps port on my motherboard. The connection worked fine for 24 hours without interruption. The next day, I wanted to resolve the issue with my 2.5GbE connection because I am paying for 1.2gbps through my Internet service provider (ISP). As some may not be aware, my Intel NIC only supports up to 1gbps. I do not believe accepting the 1gbps connection to be a solution to my connection issues for a product that is in excess of $500. I wish to have the products and services I have paid for. The rabbit hole begins. I visit Realtek’s website to update the drivers for the “Realtek PCIe 2.5GbE Family Controller” https://www.realtek.com/en/downloads I chose the “Realtek PCIe FE” link as this is the compatible driver for my controller. I can see that my NIC (RTL8125B) is listed. I then chose the “Win11 Auto Installation Program” for my operating system, Windows 11. I unzipped the file. Installed the driver and reconnected my CAT6 cable to my CAX80’s 2.5GbE port and the Realtek 2.5GbE port on my motherboard. As of this writing, the latest Realtek driver version is 1125.6.215.2022. The date the driver was published was March 25, 2022. I then purchased an ASUS 2.5G Ethernet USB Adapter to try to isolate that this was an issue with my Ethernet port on my motherboard and not the NIC built-in my CAX80 cable modem. I wanted to make sure I installed the latest driver for this device, and to my surprise, it too has a NIC from Realtek. The modem within this device (RTL8156B). Using the link from above, I chose the “Realtek USB FE” link this time. Using the “Win11 Auto Installation Program (NetAdapterCx)”. Unzipped. Installed. This wireless driver version is 1156.4.20.211. The date the driver was published was March 23, 2022. The problem persisted. Random cutouts throughout the day on both NICs. Absolutely random. Nothing I can replicate to isolate the cause of these disconnections. Final thoughts. I can use my Wi-Fi 6 via the built-in wireless NIC on my motherboard. It is compatible with the CAX80 Wi-Fi 6 connections. It works well and I can get the advertised speeds. The NIC is “Intel Wi-Fi 6 AX200 160MHz”. It does not disconnect nor have interruptions. However, the latencies are what you receive when utilizing wireless devices. This is fine for surfing the web or watching videos, but for multiplayer competitive gaming, it is not ideal. I also want to add that my Netgear CAX80-100NAS has the latest firmware: V2.1.3.7 installed on the device. A new revision of this product is needed and the CAX80 in its current production should be recalled. A newer NIC is needed that resolves these issues. I have reached out to Netgear and Xfinity multiple times and the companies keep pointing the finger and going through the same troubleshooting processes from both support teams leads nowhere. I cannot confirm the type of NIC inside of the CAX80 and their support team stands clear of identifying it. I cannot find another cable modem on the market that offers both 2.5GbE and Wi-Fi 6. I am open to suggestions. If you wish to visit Netgear’s community-based support pages of the CAX80, you will learn that this is a widespread issue being ignored. For the less advanced users who do not have the CAX80 plugged into a 2.5GbE port will not realize there is any issue at all, as the CAX80 with an Ethernet cable plugged into its 2.5GbE port to a 1gbps port will “Auto Negotiate” a 1gbps connection and function flawlessly. Unfortunately, for us who want the highest speeds offered to us must seek other products.

Title: Works as Advertised Description: 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!

I am very happy with this product and its functionality. I decided to call the customer service number for help to setup the router combo, they were quick to respond and very helpful. One of the best router combos out in the tech market hands down.

I purchased this product to maximize my gig speed internet with Cox and let me tell you, it is WORTH IT! Updating games, or downloading new games, takes little time, even with my wife streaming netflix, using her phone to shop amazon and playing music from spotify!

Works great. very easy to set up. Compatible with XFinity

Works great! comes with an app to keep updates and maintenance. This thing is a beast when it comes to speeds. Really enjoying it so far and works for everything we need it for. First modem/router I've ever purchased myself instead of renting from my internet provider and it was money well spent. Even being at a higher price point I feel it was well worth it.

Ecstatic about this product. No issues since installing this. iTunes, apps and other downloads in an instance. Make sure to hook up this to a laptop or desktop via Ethernet and complete info at Netgear website BEFORE calling your ISP.

Blazing fast speeds.....covers my whole apartment and even outdoor areas.

Easy to install. Good price for the product. Much faster modum.

If your looking to buy this route dont waste your time with it. Stay with your internet provider router/modem. I got this expensive modem in December 2025 and we are in March 2026. I have had nothing but issuses with this device. When i try to send a couple of pictures with my iphone the router blocks it. When i try to send an email with large attachments the route blocks it. This router/modem has a AI security that will block everything and consistently discount from your cameras because of security issues. You only get 30 days to access your security settings but once that expires you cant adjust the settings. When you try to call you get sent to a indian call center where you can barely understand anyone. Save yourself the money and headache and stay with your internet providers modem/router. Netgear will never get another dollar from me again.

High performance business grade residential cable modem router... Entertainment, finance, bills, communication, business, sign documents, you name it, it's all digital!

Within minutes of set up I was blazing through downloads. Just by switching from Xfinity’s XB6 to this NETGEAR CAX80, I instantly was able to achieve wireless speeds previously unheard of. My Ethernet connection on my computer is effectively useless at this point because my WiFi speeds are now steady at 930Mbps. Can’t get much higher than that. 10/10 would recommend.

Modem/Router kept dropping my internet connection. For as much as this cost and with technology the way it is, this shouldn’t have happened. Had this set up with a TP-Link Wi-Fi extender and it still dropped connection. Only a 2100 sq ft home so this should have been sufficient. After reading multiple reviews and forums, I see that this is an issue with this particular modem/router. Took it back and hooked up my old Netgear and it works flawlessly without dropping connection. Only reason I tried for the new one was for the Wi-Fi 6 capability and advertised extended range. Save your money til they figure this model out.

Easy setup online with Spectrum. Works great, I get full plan speed.

We had recently upgraded to Xfinity gig speed and had nothing but problems connecting our TVs for streaming and laptops for work. The Nighthawk WiFi 6 router/modem combo solved literally every problem we had, and even improved our speeds on top of what we should be getting. Thankful and satisfied are an understatement!

The netgear nighthawk cable modem router works very well in my home. The signal is very strong throughout. Easy to setup and connect to cable.

The modem part of this would not work with my Fios internet as a modem, so I returned it and bought a Nighthawk model RAX120 (AX12 - AX6000) Router. The router works great.

Finally had enough of my television cable provider's modem/router problems, rarely was I able to finish streaming a movie without modem failing and telling me "we have encountered a problem please restart/reset your equipment. Twenty to 30 minutes later had to resume where I had left off. Netgear Nighthawk has been wonderful. More than exceptional when it comes to streaming movies, setting capabilites and options make this modem/router leaps and bounds ahead of the unit my service provider was leasing to me for a monthly charge, and when I needed service wanted to bill me $100.00 to come out and repair replace their equipment that I pay in the neighborhood of $4000.00 annually. Well not anymore 5 Stars for Netgear , service helped me set up my new equipment with a phone call and even called me after business hours the following day to check on how my new setup was working. I would absolutely recommend to anyone.
