Perfect modem!

I've been looking for a modem for a while and doing so much research. I am so happy I picked up this Netgear modem because it instantly gave me 4 times faster speeds than what I had. No more disconnected internet or hard installation. This is the best option ever! You saved my life and the gamers/podcasters in the house are finally happy!

Easy replacement for old modem

I purchased the modem after getting an end-of-life warning for my previous NETGEAR modem -- and a nice discount. It was literally a drop-in replacement. Moved the cables over, gave Xfinity 15 minutes to provision it, and I was back online I'm getting about 150mb/s more on speedtests with the new modem than I was with the old one.

Excellent speeds! Highly recommend

Extremely powerful. Easy to setup, except the additional task of calling Cox to allow it to be recognized, since their online verification of the modem didn't work. But that's not Netgear's fault. Overall I'm getting impressive speeds over 2Gbps to my wired desktop, & over 1Gbps to my phones & iPads.
