I’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.

Easy to set up even with a long password. Works as expected just great. Product met my expectations for a cable modem. Xfinity had no problem and it works smooth once I became familiar with its operation. Looking forward to using it through all my 4K TV watching. Got next to the highest plan for speed. Options for Internet connection are available but limited in performance. I came from California where I had a brand new fiber optic cable system For less money. I hope Xfinity can deliver by today’s expectations.

The first one I ordered, appeared brand new, but would not activate. I bought this one after moving to a new apartment and didn't have any internet so I kept trying to activate it with comcast. And when all else failed, they finally told me that its been pre-activated to another account. And it actually cannot be released. So I ordered replacement. This one activated right away. Sadly, we live in a one bedroom apartment, not much concrete in these walls, but when you go from the living room - where the router is located - to the bedroom, the service drops to very low speeds. I was fine with it because it was working and I just accepted that netgear doesn't make great products. Then a few days after the 3 months mark, the WiFi SSID was nowhere to be found. I couldnt connect to the router, and even when I tried to go wired, it wouldn't give me an IP. The router was stuck with 2 LEDs constantly on, and no other LEDs would work. I tried rebooting it and nothing. I tried resetting it and nothing. I tried several times and it was the same outcome. At this point, I decided to call the tech support. That's where the real fun started. After tracking down their number and connecting, I couldnt hear the service person. And this wasn't just because of the very thick accent. Apparently Netgear support sounds like they're in the heart of India. I would hear 1/2 a second and then nothing, and then 1/2 a second and then nothing. And then half a second and nothing. Starting to get very frustrated I hung up and called again -- this happened 3 times, with the same outcome. I was trying to tell the tech that there is something wrong with their phones, but apparently they said that "ev------wa----- f----e" ... So i'm to believe that it's on my side. So I called from a completely different line, and got connected with someone completely different. THANKFULLY I could hear this person... Aaaaaaand EVERYONE Around them. It was very very very diffucult to make out a word they're saying because they were surrounded by other techs less than a few feet away. And each one is yelling into their headset in their native accent. And everyone is using the same diagnostics script that they're reading. "Have you tried resetting the router" one said. "please disconnect the power and wait 30 seconds". "This is Netgear support how can I help you". And more than 10 other voices echoing in the background. The tech then instructed me to try to reset the router and wait. Not only have I tried that, and explained it to her, I've spent a better part of my morning doing that. But I decided to entrust the professionals. Moments pass, router is reset, and nothing worked. No surprise here. She paused and then told me that we'll have to reset it to factory settings and reconfigure it. Moments pass. Pin stuck in router for 30 seconds. Power comes on. And she would guide me through it "and the light should now be turning Amber"... no lights were turning amber. She pauses puzzled. "Okay we'll try again... Reset holding the pin for 1 whole minute".... A whole minute? What the heck difference is that between that and 30 seconds. I know how to count. But Okay, one minute of pressing a tiny little pin against my finger and into the stupid hole.... Moments pass.. Router being reset.. 20 seconds... 40 seconds... 60 seconds. Relieved to be done. I let it power up naturally, and she explains "and the light should now be turning Amber". . . . . . . . . . . . . . . ."how about now?" . . . . . . . NOTHING turned amber. 2 lights. Turning white. Same as before. Same as this morning. Very puzzled. We run though the cabling to make sure that its still good. And then she comes back with the brilliant idea... "Okay Mr Tamer. We will try one more reset. This time you'll hold the pin for TWO minutes." TWO WHOLE MINUTES! At which point i opted to put the phone down on speaker so I can two-hand this operation. 2 minutes passed and nothing. Same result. I.. wanted.. to... die.. Thank you NetGear. It's been great. She asked about the date of purchase, and being that it was slightly over the 3 months mark (within a few days) they could not accept a return. However they will send me a replacement. She took down my information and we parted. I wanted to write a review then and there, but I decided to wait until I cool off and see how things progress. An hour later I get a call back from them, they are informing me that the warehouse has no available routers in that model, and they will send me one as soon as they have any in stock..... Whaaaaaaat?? So not only do I have a broken one that they wont take as a return, but they cant even send me a replacement. It's been 3 months and half on this $450 piece of crap. Two days later, I get another call. It's NetGear support for the replacement router. The warehouses are STILL out of stock and they can't send me another. So I ask her, can you send me a cheaper model or something else in return? I dont even need the same model. She actually YELLS BACK, "No. They will Send me one. Once they have more in stock". I could not be more in shock, so you called me up, out of no where to Yell at me for not having stock? And I bought the expensive model, and because of that, they cant give me a replacement? It's now been over a month since they've called. And I STILL never got a replacement for this. So after my first call with them, I figured I'll go straight to Costco for a spare comcast wifi router. And maybe I'll return it once I get my replacement. Unfortunately the only one they have was Netgear Nighthawk, the lesser model. After spending yet another few hundred bucks and a few more hours to get it to activate - with comcast as well. It's been working with very very bad signal, even 15 feet away from the router. Yet another nighthawk disappointment. And now it's passed the return date, so even if I get a replacement I'm screwed. It's been by far the worst experience ever. Do not get anything nighthawk

We moved recently and got a new internet service provider. While the provider and their service was good, the Modem Router that they rented to us was not. We were having constant DNS errors, sometimes the Router would just reset itself, and we would see significantly lower download rates than we were promised. We tried having them replace it with another rented router but the issues continued. Then I decided to do some research. As someone who games and works from home daily I needed a device that could handle high speeds reliably. Dropping my connection in the middle of a meeting or god forbid a match was not acceptable. Then I saw the prices for your average "High End Router" that does not even come with the modem portion. Buying two $200+ devices was just too much, not to mention the worry of them arriving and not working with eachother or one of them being incompatible with my ISP for some reason. With more research I found Netgear and their very reasonable prices and high end devices. And even more awesome they actually offer a gamer level Modem Router combo. The Nighthawk was the same price as a high end router from other companies and it came with the modem built in. I ordered it and set it up. The instructions included with it were fantastic and I had it up and running in no time. A 10 minute call to my ISP later to activate the device (which the instructions also walk you through) and I was up and running and the fastest speeds I've ever had at any of my homes or with any ISP or device. I'm a few weeks in now and have had zero issues, where as before I was having network troubles every couple of days. 5 stars for sure. No complaints at all. The range of the wifi is also very impressive. I'm able to walk a good 200 feet away from my house and still have wifi on my cellphone. And I love the Nighthawk app that you can manage it with from your cellphone. It lets me check the devices on my network with a touch and disconnect any that shouldn't be there. Great stuff netgear, very happy with my purchase.

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 built in 1898 ( very thick walls) with tons of devices connected to the WiFi and wired in, 4 total 5 port Netgear switch boards, full home security cameras, plus 6 family members ALL WIRELESS and absolutely flawless! I removed my Google Network due to not needing to extend my signal anymore. 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 Wi-Fi reach that this modem has. Installation was also super easy!
