G34 Compatibility with Cable America

I currently have an older Arris model (SGB6580). I recently bought an Arris G34 modem/router. Unfortunately, I did not check with my internet provider to see if the G34 was compatible. I use CableAmerica. They informed me that it is currently in the works for the G34 to be compatible with them, but they were not able to give me a timeline. My question is if there is a known timeline for when the G34 model will be compatible with my provider? I am wanting to know if it is worth holding onto it or just getting a different one.
