I just purchased a LS220D 4TB X 2 . I want to be able to set the device to mirror. I currently have 2 laptops and a desktop that I want to mirror but want the ability to add maybe 2 more devices down the line. I can not find what I need to do to set it up this way. I have the three users defined . I am also have a problem with the quick setup, where when I double click the device ICON it doesn't proceed. How do I access the Network and Sharing center?
