Change MoCA Adapter to D bnad High Mode

Some DOCSIS 3.1 Cable Modem/Routers have a working frequency limit of up to 1218MHz, which may overlap with the working frequency of MoCA (1125-1675MHz). In this case, it is recommended to modify the MoCA working frequency to D-band High (1350-1675MHz) to avoid mutual interference. The following are the operating guidelines. Note that every device on the network needs to modify its working frequency band and LOF values. After modification, the device must be restarted to take effect.
