After S2 App update bombed out my library i have reconnected again.

Here is how I did it using a Synology DS124 NAS.

I followed instruction for SMB and shared folder settings at:

In the NAS setup/admin:

• All the music files are in NAS shared folder \music.
• Installed the Synology “Media Server” app on the NAS and set SSDP advertisement interval to 10s to allow DLNA access to NAS.

In the SONOS S2 App added the shared folder:

• //192.168.50.4/music
• User is your NAS login username.
• Password is you NAS login password.

Note use of “/” in IP address, not “\”.

“192.168.50.4” is the IP address my router has allocated to the NAS. Using the NAS’s network name “Server Name” did not work. The risk with using the IP address is that if the router reallocates the IP address then you will lose the link and will need to relink shared folder with new IP address.

Good luck.
