Ready NAS DUO V1, Windows 10 can't set back ups and other network issues!

First go into "turn windows features on and off" on the PC and make sure the SMB 1 client is enabled.

Then troubleshoot file explorer.  First try entering \\192.168.0.27 into the file explorer address bar (being careful to use the correct slash direction). 

If it asks for a network password, then you can try using admin as the username and the NAS admin password for now.  Though it is better practice to create a NAS user account on the NAS, and use that username/password instead. You can also set this credential in the Windows Credential Manager.

Once you confirm that you can reach the NAS using the file explorer address bar, then move on to backup.  Try entering \\192.168.0.27\sharename into the network location field at the bottom of the "select folder" window in your screenshot.  Use the real sharename of course (and be careful to use the correct slash direction).

Overall, clicking on the icon in the network list only works if the NAS is listed as a computer (and in your case it is listed as storage).  There's no way I know of to fix that.  The workarounds are

• set up desktop shortcuts on the PC that open file explorer with the correct share
• add a network location in the main file explorer window
• just get used to entering \\192.168.0.27 or \\nas-name (using the real name) into the file explorer address bar.
