Review: works well - works well
Review: Plug-n-Play, absolutely zero hassle or headache. - I put off replacing my Comcast/Xfinity rental modem/router for way to long. If you are browsing and halfway considering doing it, buy this modem. 1. It's significantly cheaper than the brand new version since it's certified refurbished. It looked brand new out of the box and I had zero issues during set up. 2. It's a Comcast/Xfinity supported device. You literally plug everything in (same exact cords on the back of your rental modem), go into the Xfinity app, set up new modem, and type in the MAC address on the bottom of the unit, wait a few minutes, and set up is complete. Boom. Your set up is done. $40 and you no longer have to pay the $17 a month or whatever it is for the Comcast/Xfinity rental. For anyone who is confused, this is a modem and not a Modem/Router combo. You need to also buy a router that you plug into the back of this which gives you your wifi. I coupled this with the Google Mesh Wifi 3 pack (which was about $180) and now I have consistent, fast wifi in all areas of my house. Not a single complaint.

Works fine but expect to have to replace it when a storm comes over. And they will not repair it.
