I've got an ASUS RT-AC68U wireless router and am really struggling connecting to a music library on a USB.
On my old router, I just plugged the USB in the back and entered the appropriate path when defining the music library location in Sonos and it all worked fine.
With the new router, I can't figure out how to connect Sonos to the USB stick plugged into the back. The router's USB config utility gives me an option to setup a UPnP media server, which I've done (because I've read that Sonos is UPnP-compliant), but I don't know if that's the right thing to do. I still have no idea what the path is to the USB stick, or how to access it. I've downloaded and read the relevant section of the router manual, but I'm still stuck.
The ASUS range of wireless routers is pretty common, so I'm hoping someone can help me sort out what should be a really simple problem.
