Great
We moved and had to get a new internet company. We now have Comcast and they said we needed to either rent from them for $10 a month ($120) a year or we could purchase our own..for $100 or so..well, I went on walmart.com and found this one with great reviews...bought it and had it delivered to our store and it was there in just a few days. We hooked it up and then hooked up our wireless router and wallaaa...we have internet. Awesome! Would highly recommend this!!

Works great
I got this modem as I was switching ISP and would be getting a discount with having my own modem. It is doing great pulling in over 200MB down stream and matches perfectly to my ASUS (RT-AC68U) router. I've had Motorola in the past and this is every bit as good. Go for it, get it!

Great Buy!!!
The Netgear DOCSIS 3.0 was very easy to install. I called my internet Provider (TWC) and the agent activated the modem, it worked without any problems. I haven't had any problems with it at all thus far. I am very happy with this purchase. I also have owned the Netgear Router for many years and have had no problems with it either.
