I understand this is an older post, however after searching for an answer on how to connect my chromebook (Acer 14) to my older WD MyBookLive, I found that none of the recommendations worked, so I decided to troubleshoot this myself and have found a work around that works perfectly for me.
You will need to download CX File Explorer from the PlayStore. After installing and open, do the following:
-Network
- Add “+”
- Remote
- SMB
- Enter the IP of your MyBookLive, as well as the username and password, and connect
Following these steps I was able to connect to my NAS and access all files. The one thing I have not been able to do however is open movies that are stored on there, from my Chromebook.
Tip: You can also select the “Anonymous” option after entering the IP address, instead of entering the username and password, and it should still connect.
