How to Activate Arris CM3200A

Activating your CM3200 cable modem with your internet provider is something that needs to be done in order for you to receive internet access on your devices. Generally, most activations take about 30-45 minutes.

  1. Plug in your new modem the same way as the one it's replacing. You'll want to make sure the power cable is plugged in, as well as making sure the coaxial cable is screwed in on the back.
  2. Next, wait about an hour so that your modem can download firmware needed for activation.
  3. Then, call your internet service provider for activation. Since the Arris CM3200A is compatible with many different providers, we recommend checking your internet bill for a customer service number, or if you're using a kit provided by your service provider, use whatever number they have listed in your instructions.
  4. Once you call your provider, they will ask for several numbers on the bottom sticker of your CM3200. We recommend taking a picture on your phone so that it's easier to read off to them when requested.
At the end of the call, they'll confirm with you that you have internet access and confirm that your modem has been activated![/vc_toggle][vc_toggle title="Arris CM3200A Login Instructions" style="round_outline" size="lg" el_id="login"]Logging into the interface of your Arris CM3200A cable modem is a simple process that allows you to edit the settings of your modem to better suit your home network needs.

How to Reset Arris CM3200A

Resetting the Arris CM3200A allows you to change all the settings back to their factory default. This can be helpful in a variety of troubleshooting situations and is always a good thing to know how to do.

  1. Plug in your Arris CM3200A and allow it to power up for 5 minutes to ensure it's fully booted up.
  2. Locate the reset button on the back of the modem near all the ports. The button is located inside of a really small hole on the back, so you will need a paperclip or something small to press it in.
  3. Press and hold down the reset button for 30 seconds to ensure it is fully reset. Then release and allow another 5 minutes for your modem to boot back up after it resets.
Now your CM3200A cable modem is reset!
