Hi
Most usb to rj45 network adapters I have seen require a device driver
What operating system does your radio use?
What device is recommended by grace?
It is not clear what chipset the recommended usb to Ethernet uses
Which does have a driver included
But you have to switch off, connect the usb to Ethernet then power on again
