    I love Netgear peripherals. We decided recently to cut the cable and we wanted a modem that would be upwards compatible with Comcast. This Nighthawk cable modem is amazing and easy to setup on comcast/xfinity

    Replaced my internet providers modem. And so far, there are no drops or laggy connections. It's been hooked up 2 weeks, so I will give it more time to really give it a run for the 300 dollar price tag.

    I bought this because Comcast recently upgraded the network in my area and my Motorola wasn’t cutting it anymore. I am running this with Xfinity 1.2gbps. I’m averaging 1.4gbps download and 240 upload. Set up and activation was super easy.

    Modem arrived earlier than expected. Installation (Xfinity) was flawless with Xfinity customer service. This replaced Arris S33 that failed within 8 mos. I am consistently getting speeds above 1.2 gigs (my plan). So far it’s great, time will tell.
