    A Better Choice than the Arris Surfboard

    A new Arris Surfboard that I bought from Best Buy three months prior just died suddenly. I had a Best Buy Geek Squad contract on it, but since it was still under factory warranty I had to sent it back to Arris for replacement. I bought this NetGear as a temporary solution. Guess what, in the three weeks it took to get a replacment from Arris, this Netgear has been flawless. It stays connected more steadily to my Xfinity service and I haven't had a single signal dropout. The NetGear is staying put, I like it. It's bigger than the Arris Surfboard, but as long as it works as well as it does, it will stay my primary Modem, and I've been a Surfboard user for going on a decade now. What makes it great is it connected automatically to the Xfinity service, where I had to make a phone call to Xfinity on the last two Surfboard models to even get them to connect.

    I’m not a techy so can’t say too much about this as my knowledge of computers, modems and routers isn’t great. I WILL say with my new modem I’m getting the speeds I was supposed to and even though Kyle H from geek squad hooked it up, it seemed to be a pretty easy process. Overall very happy with this new purchase

    The product worked as good as advertised the only problem I had was with my isp and an issue on my line so I would say this router gets 5starz from plenty of runtime by now.

    Netgear has always been my go to for internet and networking. Their products are high quality and easy to use while not breaking the bank. Yes, they sometimes cost a bit more than the alternatives next to them, but I have never had an issue with Netgear equipment.

    So far so good, get 1 gig speeds on Mediacom plan. Make sure to call them so they register the device MAC address (as stated in the instructions).

    The modem was a bit pricier than ehat I am used to paying for aodem, but we were in need on a set up capable of lushing a gig. So far, it gets the job done. I probably would have went with the other model that has extra ports if I had the money.

    I bought this modem due to concerns of other modems footprint. Fits perfectly into the small space I need it to. Set up and install was a breeze, aside from contacting my internet provider. (Friendly reminder: always check with your ISP to ensure your modem is compatible with their system)
