Review on 📶 ARRIS CM820A DOCSIS 3.0 Cable Modem - Latest Version with Quick & Easy Activation by Shane Picot

Works with my 100Mb Comcast connection. Update April 2018 --------------------------------- ------------- - ---- ---------------- I've used this with Comcast for years. This is a fantastic modem. I'm getting 97 Mbps on my 105 Mbps Comcast connection right now. Yes, it's an old DOCSIS3.0 modem with an 8x4 connection that still works. If you're on a serious budget, I think Revain offers refurbished versions for $25-$30. If you're looking to buy a modem now and for years to come, I'd look at 16x4 or 24x4 tethered modems (DOCSIS 3 of course). I can tell you. I won't buy a new modem until this helps. I still rate this purchase 5 stars. I have no problems. I immediately gave Comcast access to control the modem and they have never let me down with problem calls.
