    The BEST option.

    I’ve had this Modem Router for 2 years now and it continues to perform both wirelessly and hardwired. Do yourself a favor and tell your internet provider to keep their garbage modem / Router combos preferably the day they come to install the internet. They are the biggest scam ALL internet providers run. They will charge you 10 dollars a month FOREVER to use their terrible routers and if that’s isn’t comical enough I’ll tell you what is. You’ll never see the speeds you pay for using the provided routers from any company, most would think Xfinity has solid ones but I promise you they don’t and never did. I used to work as a Geek squad home install guy and every time I saw one of the internet provider boxes I knew my job was going to be harder that day lol.. The best investment you can make if you want a future proof modem that is sure to be relevant for years to come. Wifi speeds are impeccable with gig speed (Mediacom) cable internet. The Fastest speeds you’ll see come from the multi gig Ethernet port on the back using a high quality Cat 8 line. Do not use Cat 6, trust me I literally doubled my speeds to both my Xbox Series X and my laptop, switch to cat 8. I’d suggest the Netgear Nighthawk AC1900 if you have gig speed and are more on a budget, it runs about 200 and will still outperform every cable company’s little crap box they give you and best yet your bill goes down 10 a month and you OWN it. I just installed one at my parents and they are getting very solid speeds for that price range, also fixed their security camera issues as the “new” modem Xfinity gave them wouldn’t communicate with the Blink cameras! This unit and the Nighthawk AC1900 both have 2.4 ghz and 5 ghz channels. Use the 2.4 ghz for longer range wifi (security cameras, smart switches / bulbs) and the 5 ghz signal for Tablets and Smartphones / computers (hardwire when possible with Cat 8 and a USBC to Ethernet adapter if your device doesn’t have an Ethernet port if you want max speeds and less traffic. Wired is still king, run it whenever possible. That includes your smart tv, you’ll never see anything buffer again on it.

    Super fast speed

    I work from home 3 days a week. I have a 3000sq ft home with a basement a back deck, two ring cameras and two college kids. During summer holidays was the worst, with me working, my son playing games on the Xbox, my daughter on a video calls, my wife presenting to her team, and I am on calls at work which keep dropping and loosing connection (poor network signal error message) - so annoying. Solution was to shut down the ring camera (motion sensor was killing me everytime it uploaded a video). Buy (2) 100 ft Ethernet cables to patch into the modem directly which was not the best option because I had wires all over the house which was not ideal. Could not get a Wi-Fi signal in my basement when I worked out and had 1 bar on my device on the back deck - waste of time to browse outside in the evenings or weekends. I broke down and bought this modem, life changing experience. - 4 bars all around the house, including basement and back deck. - No issues with the ring cameras now - Download speeds of over 490-520mbps, upload speeds of 21-24mbps - when browsing the web, page loads like the flip of a page on a book. - Everyone at home working, streaming, browsing the web, all devices active and online - highly recommend BTW I am on Xfinity and am supposed to get up to 1000mbps - I used to get 150-200 on a good day on my old modem, when I am home alone

    Worth Every Penny!

    After my internet provider was charging me monthly to use their modem/router, I looked at buying a 3rd party modem/router that was compatible. I landed on this model because I needed something that could support my higher speed plan and I wanted an all in one modem/router rather than having a modem with a separate router. Setting up the AX8 through my provider and through the netgear app was fast and easy, I now have more control over my home network. I have noticed I have faster speeds and more coverage with the netgear AX8 than the modem my provider gave me. I used to have drop outs and buffering when streaming, but I haven’t had that since switching. So far I am very pleased and definitely recommend this product

    Worth every single penny

    I had a Motorola router before and it was terrible. It didn’t want to connect at times, because my internet connection was so strong. With this one, it’s absolutely amazing. It is so fast, I don’t have to worry about losing or dropping connection. Definitely worth every single cent… and there was a lot cents I had to spend lol
