C6300BD Switching Internet Service Providers

Not sure the correct Model is attached, C6300BD AC1900 on front.

 

Switching from Cox to Comcast in the near future, looking for options to use the same hardware as nothing is wrong with it.

 

Will likely need to do something to install new firmware or something, anyone know of anything to allow this hardware to be used by a different ISP. Bought this a year or so ago to avoid monthly fees and am now relocating into a similar situation (rent or buy a new modem, or find a way to make this work for the situation).

 

Hope some NETGEAR tech's or knowledgeable community members can shed light on how this would be possible.
