Is your internet service provider offering this? If not, opt for an alternative.
I don't understand your service provider, but they likely have a catalog of "approved" modems. You could reference that catalog or select from it. Sharing your internet speed details might also be useful. The device I'm using is the Motorola MB8611.
Modems are designed for particular internet connections. Which one do you use—DSL, coaxial, or LTE/5G?
