    Fast speed access to the internet, programs run smoother & the device itself is upright & doesn't take up a lot of space. I prefer the modem & router to be separate as it is cheaper than having to replace a combination unit of the two devices in one package.

    Works as good as any other modem at a good price.I was worried that it might not work with time warner but it does. Is silly to be renting a modem from your cable company at up to $10 per month. Go for it

    It was very easy to install and set-up. I love it's compact design. It is slightly larger than a smart phone. It works great with my current ISP which is why I had to replace my "old" modem.

    this works great, didn't even have to call Comcast to have them set it up on their end. just had to log into my Comcast account. Works even better with my wireless router than the rental modem

    Excellent performance with the service i pay for. Pays for itself in no time considering the rental fees the cable company charges you. No slow downs, small and compact and doesn't get in the way. Highly recommended.

    I currently have my internet service through Time Warner Cable. I got this modem to work with their 50mbps downstream service. I get the full (sometimes more) 50mbps downstream. I haven't had any problems with connectivity using this modem. It was an uneventful, simple, plug and play installation. It has a very small footprint. It's quiet and the lights on the front panel are not too bright. I also have the appropriate airspace around this cable modem which keeps it running at room temperature. After about two months of using this cable modem I haven't had any problems with it. I am very happy with this product and would definitely recommend it.

    I just upgraded to a faster internet speed, and the modem provided by my isp was not working. I bought this, hooked it up, and boom. It works perfectly. I love netgear and will continue to purchase this brand in the future.

    I had to replace my modem & this one was by far the best deal. Small, lightweight, and internet connection speeds are higher than my ISP guarantees -- I'm paying for 60 Mbps & getting 70 Mbps.

    I am using this cable modem to replace the one my ISP sold me. This works much better and I don't have to reset it all the time! This cable modem was easy to set up and connect to a WiFi router.

    I wasn't sure how much of a difference it was going to make versus my cable provider modem. To my surprise a lot. I never have to reset it. It never freezes up and never buffers. I hoped it was going to do better than the old one and it really has made a difference!

    It's a small compact modem with no bulky transformer on cord. It handles advanced speeds just fine, and doesn't cost an arm and a leg.
