    Upgrade to this from an older docsis 2.0 modem. Didn't really change my upload/download speed like I thought it would but that's problem do to my poor spectrum cable.

    I’m giving 4 stars because it’s impossible to use those tiny “legs” that they give you for the standup possion of the modem. The cable is just to heavy.

    Worked fine when connected to Spectrum, once activated (have to call them to activate, which is much harder than it should be, but not the fault of the modem...)

    I purchased this along with a Netgear AC1900 Nighthawk router. I wanted to stream on multiple tv's and use 10 or more wireless devices without issues. Works great.

    I bought this hoping to replace the rental provided by my ISP but it worked about the same. Still provides a stable connection and linked to my wireless router no problem.

    Bought this modem and a Netgear router to replace my rental modem from Comcast. This combo has better coverage than my Comcast equipment and saves me $10 per month.

    No complaints so far. Haven’t had the product that long but so far has worked well. The stand doesn’t work very well would be my only complaint.

    I've had this guy about a month and a half and it has been solid so far. My internet needs are really light at the moment but there hasn't been any lag or slowdown.

    I purchased to eliminate the modem rental fee with my cable company. I don't play games or watch many videos on my computer. I do have a smart TV and it's working fine.

    I got tired of paying the cable company and with a little help from a sales associate I was successful. And it was on sale. And I had a coupon that worked too!
