I returned home yesterday, following an extended period away, during which time the system has been shut down and unplugged from the wall power outlets, and the ethernet cable which runs from my router through to the music room disconnected at the Cisco switch.
The setup is basically … TalkTalk router > Apple AirPort Extreme base station, running in “Bridge” mode, and which runs a separate “Dave’s wifi” network for music, which I need to have a decent signal to allow for iPad control in the music room. This feeds a long ethernet cable to a Cisco switch, which has both the HDX server and the ND555 connected.
Since plugging things back in, the Naim app generally finds the streamer as before, but soon after, I’m getting the “streamer not responding” message, and the music then shuts down intermittently. Occasionally, I don’t get that far, as the app is “unable to find rooms”.
I’m assuming that there’s a networking issue going on somewhere, though I’m baffled as to why that might be, as everything has been restored exactly as before.
I’ve done the complete shutdown / restart of everything from the router, the Airport base station, the Cisco and then the HDX and ND 555, and also in the reverse sequence, all to no avail.
I’ve also had a look at similar earlier topics, and took note of a reply from @davidhendon where he suggests a conflict between the actual IP address of the ND555, and the one the app is expecting to see. I can confirm that the streamer’s IP address, per the front screen, agrees with the one shown in Net Analyser, but I can’t get the app to maintain contact with the streamer long enough to be able to see the address for which it is searching.
I’ve attached a couple of screenshots, showing the connection to the HDX, and another showing the status of the separate “Dave’s network”
Has anyone got any suggestions before I start pulling out what little remaining hair I still have?
