I also have a “SMB1” problem with my MyPassport Wireless Pro, and whilst I can connect to the dashboard I can’t read/write the data on the drive from Windows via Wifi. The error message from Windows 10 Fall Creators is:
"You can’t connect to the file share because it’s not secure. The share requires the obsolete SMB1 protocol, which is unsafe and could expose your system to attack. Your system requires SMB2 or higher. For more info on resolving this issue, see https:/go.microsoft.com/fwlink/?linked=852747.
This link, in a nutshell, says WD need to update the My Passport Wireless Pro firmware to use SMB2 instead of SMB1. Earlier versions of Windows allowed use of SMB1.
