I don’t own one because I have two WDMYCLOUDS. You may want to check with WD or wait for an owner to answer. Did you try the online support links shown at the beginning of the User Manual?
Did you see this?
Internet Connectivity My Cloud Home devices must be connected to the Internet. They should be connected to
an available router through the included Ethernet connection. (This is not a Wi-Fi®
device.) Gigabit capability for the router or switch is recommended to maximize
performance. The router requires a Broadband (WAN) Internet connection with an
Internet Service Provider (ISP) for initial setup, software downloads and for accessing the
device.
