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

This modem worked fine from the start but I spent half a day setting it up at the cable company. They said they don't support it, but I used their modem, that's the exact modem I bought. They just wanted me to upgrade and use the money to rent their new Super Wam-O-Dyne modem that doesn't get any better than this. I have a Netgear Wi-Fi router that completes the system. If you need your own modem, talk to someone other than the cable company and set up your system the way you want.
