    Fast, reliable modem‑router combo that handles heavy streaming and uploads

    I bought this modem and router combo about a year ago, and it’s been solid from day one. My internet stays fast and stable, and I haven’t had any random dropouts or slowdowns. I consistently get over 250 Mbps, which lets me upload long videos to YouTube while streaming at the same time without any issues.The setup was simple, the connection has been reliable, and the speeds are exactly what I need for heavy daily use. After a full year, I’m still very happy with this combo — it’s been one of the best upgrades I’ve made for my home internet

    Outstanding value at the price

    Bought this combo modem/router because my old one was having issues staying connected to the internet. Received it, set it up with a direct connection from my PC, then a quick call to Optimum to have it provisioned and off to the races. I have since downloaded the Nighthawk app and been pleasantly surprised at the ability to easily manage the router. The speed both up and down are very good. The WiFi setup was easy, opting to go with Smart Connect has been a great success, one network name for all devices connecting. Would recommend this for anyone who is looking to pay for their modem once ra

    You won't be disappointed...

    This works GREAT. Easy to setup, well worth the money. This is my 3rd upgrade to my home system and was by far the easiest using the instructions. The Nighthawk app and software is the best so far..You would not be disappointed in buying this NETGEAR system.

    Upgrade

    I was renting my modem from Mediacom. After I had upgraded to their newest model, I had nothing but issues. My speeds had dropped significantly (as low as 25Mbps), and the modem would disconnect several times a day. I spent 2 weeks with Mediacom trying to fix the issue, but nothing they did worked. I was starting to get frustrated because I was paying for services and equipment that were not working. I work from home a couple of days a week, so I need reliable internet. I had decided to stop renting and buy the Netgear Nighthawk AX6. It was very easy to set up with Mediacom, and it only took a

    Recommended for large home

    So my Orbi cable modem/router that was more than 7 years old. I went to Xfinity for options and received a modem/router that was no extra charge. After a week of short term offline experiences I called Xfinity and wanted help. They sent out a tech who said all my cable was testing good. Second modem installed. Immediately found the same issue of short term outages. Then the bill showed up for a $20 increase in the monthly and $100 for the tech visit. Researched options and found the Nighthawk and ordered it. 3 hours later I finally had it setup and after a week I can report it is excellent! Ou
