I need a software frequency range must be from 5/42 to 5/65

Hello star22

                       Basically software on the modem will be updated only by the Internet service provider so even about the software range will be confirmed and confirmed by them. The Cable Operators (MSOs) have complete control of what cable modem/gateway hardware they will allow installed and the firmware it uses, this is because they own the coaxial cable that is connected to the ARRIS model, because of that the Firmware updates are pushed by them, and any update needed as well. Any associated firmware updates are automatically deployed by the cable operator. This is not an ARRIS only implementation, but the required implementation of any cable device manufacturer.
