    NETGEAR - Nighthawk - Fast and easy to set-up!

    After owning a Motorola Modem/router for over 12 years, It was time for an up-grade. I purchased this NETGEAR - Nighthawk AX2700 Router with 32 x 8 DOCSIS 3.1 Cable Modem at the recommendation of the ISP technician that came to my house to diagnose a minor issue I was having with my internet. I have to say, and I hate using this cliche, but the set-up of this modem/router was so easy that a caveman could do it, but it was! It took me longer to remove my old Motorola and un-box the NETGEAR modem than it took to set it up! Once it was plugged in and hooked up to my P.C. & cable, I called my ISP, gave them the I.P. address & model number, and within 10 minutes I was surfing the internet! Total set-up time was approx. 40 minutes! Then all I had to do was change password for the router & create a unique passcode for the devices to connect to it! Then I performed a speed test from my ISP's website, and just by upgrading to this NETGEAR AX2700, I gained 124mbps! It's been 3 weeks now and no issues! I have a good strong signal thought out my house and it hasn't dropped of the internet once since I hooked it up! In closing, I highly recommend purchasing this NETGEAR - Nighthawk AX2700 Router with 32 x 8 DOCSIS 3.1 Cable Modem as it was easy to set-up, it’s really fast & reliable!

    Fast, reliable & easy to use!

    I was renting my modem from xfinity. 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 I day. I spent 2 months with xfinity 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 Xfinity and it only took a couple of minutes to set up with the Xfinity app. I’ve been using it for a couple of months now and it was worth the money! I have the gigabit plan. My speeds have been consistently around 900Mbps and the modem / router has been very reliable. You can download the Nighthawk app and use it to revoke access to any connected device, pause the internet on any connected device, check your speeds, check your data usage, reboot the modem and even create a guest WiFi with a different password. You can access your network remotely with the app. It also has a “Smart Connect” option, which automatically selects the fastest WiFi band for every device. I’m very happy with this modem and would recommend it to anyone who wants to get away from renting one from their provider or if you’re looking to upgrade

    fast and easy

    wow, I really like this router. You have to wonder why I have been paying my cable company $14 per month for the last... oh 100 years... to rent their lousy router??? This NightHawk is built for speed and easy use. It just never goes out, the internet is always there for me and lightning fast. I do have it plugged into a battery backup - duh - I learned that lesson once upon a time. This 6 stream dual band WiFi 6 router keeps all your devices happy at the same time, You will appreciate how reliable it is on multiple devices. And yes, simple set up.

    Easy to use! Worth the money!!

    Easy to use and setup. I have xfynity and with the use of the xfynity app and the netgear app my new modem was up and running within 10 minutes of the apps updating its software and setting up the connection. All i did was put the app to work and walked away. 10 mins later my whole internet was up and running all i had to do was rename my connection and setup the password! Highly recommend for anyone looking for fast speed and beginner level modem shoppers
