Hi (new user here), did you get your issue solved? I’m on win8.1 and had a similar issue.
My device name would not show up in the network panel of win explorer (yet on my brother’s computer it did show).
I had to type in “\[device name]” into the file explorer window.
But now I fixed my issue by turning on network discovery for “public” and guest devices (it was already on for “private” networks).
Not sure how you do it in win7. But maybe try a google search to enable network discovery for “public” and guest devices. Then my device showed in the network panel.
Also the mapping shares (using the WD app) did work, but not perfect.
It created folders going to the LAN IP of my device, and named after each shared folder: “Public (\184.108.40.206) (F: )” (It turns each folder into a drive mounted(?) by windows, and shown in the “Network locations”).
But when I rebooted the device, its IP on the network changed (220.127.116.11 to 18.104.22.168). So now I have old folders in my list that do not refresh.
