not better off but you cannot use the iburst terminal over ethernet, only usb thats why you have that icon, you may as well shut that program off its useless to you on ethernet.
perhaps plug into usb to get details info on your connection, so you can tweak it as you will get a better signal read out than the leds on the unit and a frame error rate, it also shows how much you downloaded and the system tray icon blinks if data is sent or received, aside from that it doesnt do anything fancy, its a simple app
