Bests & Worsts Reviews from Amazon

I purchased this modem for use with my new gigabit service with Comcast Xfinity. Constant disconnect issues. At first I thought it was because there weren’t any telephony lines and Comcast was trying to provision voice. When it failed, it would be disconnected. I wasn’t using voice, so I took it off my plan... and continued to have issues. I got wise and started researching (Google “MB8600 Comcast Disconnect) and found several others with issues. I decided to buy a Netgear CM1000. Got it set up with Comcast in just a few minutes and it’s been rock solid. Not sure if this is a bad modem, or needs updated firmware, or if the issues happen to be on Comcast’s side (even thought I had several techs come out and check my house’s wiring, all the way up to the equipment on the pole), but the Netgear works as expected and this one doesn’t. I missed the return window and can’t get my money back. Heed my warning; don’t lose money like I did.
