Midcontinent doesn't support this model as a modem/router in one, so I just used my old router.

Worst support model I have ever dealt with

I use comcast and wanted this to avoid cable clutter, I suppose it is time to look for a better model.

Model number, serial number, and MAC address

Time Warner has an approved cable modem model list and a unsupported model list, and this model was not on either list, but I called Time Warner and with just the MAC number printed on the bottom of the modem, they were able to activate this cable modem on my service in under 10 minutes
