Sounds like you have the same problem many others have with Windows 10 and the My Cloud not showing up properly. See the first tacked thread of this subforum…

The way to manually map a share if the My Cloud doesn’t show up properly in Windows File Explorer is to use \\wdmycloudname or \\mycloudipaddress in the Windows File Explorer address bar which should open up the My Cloud and allow you to right click on a Share/Folder to select the map network drive option.
