Where have all the songs in my playlist gone??

Not sure how US handles playlists. does it create a .pl or .m3u file somewhere in the synology. if so and you can open these files as txt files it may be that the synology's old IP address forms part of the individual tracks' file location. if that's the case you might be able to edit the playlist txt file to the new IP address assuming this changed when the router was reset as you have suggested.

I think that indeed the ip address forms part of the file name (or folder name), unfortunately.  

In that case Richard might want to assign a fixed IP address to his Synology NAS so that he doesn't have this issue in the future.

true unless that ip address has been assigned to another device on his network.

Everyone, thanks for contributing...ok so it's because the IP address changed. So where do I find the playlist so that I can change it?

The other option is just to rebuild my playlist of songs (which is a pain) but doable...

Hi sj -

Well, sort of... Anyone delving into static or reserved IP assignment will have to learn a bit about the rules and pitfalls, which is what I think your excellent warning is about.

Might be simple to power down the device now using the old IP and start again. That said, if the old IP address is to be (re-)assigned to the device as a static IP, it must also be removed from the pool used by DHCP (and can first be un-assigned from whatever owns it first). Also of interest if the DHCP server (via the router config page in most home set ups) supports it is to keep using DHCP to assign the IP but request (usually via a check-box) that a "reserved" (ie guaranteed constant) address be given to the device.

Either way, this requires a little learning first but is straightforward and quick to implement. Possibly quicker than working through the editing of playlists (hence my suggestion).

Please note: I don't have a UnitiServe, so I have no idea how one would access the playlists, nor whether a script to update the text playlist files would be possible. Nor do I know whether an IP name could be used instead, whith the DNS and DHCP ensuring that the static device name would resolve to the (possibly variable) IP address. Just thinking aloud here, as this is a networking issue, not specifically a streaming or serving or Naim issue... Offered in the spirit of exploring options and learning how things operate underneath the audio front end.

Hi alan

Yours is a good idea and if Richard has a note of the original ip address (probably in the format 192.168.1.XX) and is confident in configuring his router then yours would probably be the preferred solution over editing the playlists.

As I mentioned in my initial post I also don't have any experience with the UnitiServe other than comments I've seen on this forum so I'm not sure whether the playlists would be stored on Richard's Synology NAS drive and in what format or on the US's internal drive.

Thanks! So I am now looking for where the playlists are found because I cannot remember what the previous IP addresses were! 

It looks that way. If you can find and open the playlist files as text and the individual track filenames/folder names do include the old NAS ip address then make a note of it and, if you can, reassign that address back to your NAS via your router config as suggested by alan.

Otherwise you will need to edit the playlist txt files or rebuild the playlists.

I believe that US uses a software interface named Desktop Client but I don't have any experience of its functionality and/or whether this can be used to edit your playlists.
