It Doesn't Work.
Reviewed in the United States on May 14, 2019
Long story (about 6 hours long, actually...) short:
Had a perfectly functional setup of Motorola modem/NetGear router until we decided to replace our reliable SurfBoard with this product.
This modem works - don't get me wrong. But not only did Xfinity take over an hour to get it registered and up and running (a process that usually takes 5 minutes), but as soon as you try and connect a router to this you'll realize it doesn't work.
I'm sure it's SUPPOSED to work.. but it sure didn't. Mind you, we were connecting it to a Nighthawk NetGear router. After spending 3 hours with NetGear on tech support they finally dropped the pearl that "..your router must be broken."
After dismissing them, plugging back the old modem, calling Xfinity again (..and, voila, having the modem up and running in literally 2 minutes...) BEHOLD, my friends, the miracle - as our router RISES FROM THE DEAD, and works flawlessly as it always had before.
As far as I'm aware, until someone posts a review that dictates this modem works with routers my personal experience is that it doesn't. Even if it does, and we got a defective unit, a two hundred and thirty dollar modem that took 6 hours of tech support to simply fail miserably at being a modem is probably not worth your time.
