No Rooms Found

Can your app not connect EVER, or is it sporadic....  Does killing the app and then restarting it have any effect?

David - are all your other rooms/streamers on-line at that time?

It will be helpful to tell us what & how your network is connected, wireless hub name/make, switch (Y/N) all ethernet, part wireless / all wireless.  Control point iOS or Android  .......  I see you have a US

But whatever the above I would try a complete system reboot - turn everything on the wireless hub off & leave it off for at least 5 mins.  Restart the wireless hub & let it complete its start sequence,  next start the switch (if you have one)  then US, then NDS & finally control point.    On the naim app screen you should get a picture of Naim units & the bottom bar says 'Find My Room'  touch that & it will show you the NDS (named by whatever name you have assigned to it)    touch that & it should be OK & stay OK each time you start up.  

Thanks all for your suggestions. I have just one room, all components connected via a switch, and the switch connected via Ethernet over mains to a modern router (can't be more specific right now, as it's in my son's bedroom and not immediately accessible). Control point is an iPad, and as a result of this thread, I have selected a different wireless network connection, with (apparently) some success. Will keep you updated.

Thanks All,

David

is the wifi access point on the router? If so you are probably finding your ethernet over mains is getting in the way - perhaps preventing the multicast discovery messages - hence the no rooms found. Ethernet over mains is a  kludge and I really can't recommend it other than for very basic network usage - not to mention the RFI it can cause.

Simon, you are speaking in tongues here. Multicast discovery messages??

I know about  the drawbacks of Ethernet over mains but I really have no option, and the setup worked very well until the recent change to Nstream.

Something was amiss if your iPad was connecting to the "wrong" wifi network.  Do you have 2 wifi networks in your home? If so that can certainly confuse things.  Or was the iPad trying to connect to a neighbor's wifi?

In any event, yes, this will only work if your iDevice running the Naim App actually connects to your home network

When I get this message on the app (both iOS & Android), I pick up the Naim remote, and hit the "center" button twice; once to say no network, and then again to make it start looking. Usually brings my 272 into view of the Naim app...I'd say about 90% of the time.

It was not connecting to the 'wrong' network, but I was accessing it via a range extender, which may have been giving me problems. Will research some more tonight!

Some 'range extenders' are crap.  I've not tried nearly them all, but the way Apple does it works really well in my home.  I have two Airport Extremes, one in 'extender' mode, and the wifi is full speed and spot on throughout my home.  So your range extender could be a variable that's causing you grief, definitely. I'd disconnect it and see if, when you're standing close to the wifi source, the app works reliably. If so, bin the range extender.

The Apple stuff works well for me too, and it's very easy to set up with no technical understanding required. I have an Airport Extreme connected to my ISP router, on which I just disable the WiFi, and an Airport Express two rooms away, both the intervening walls being of very thick stone. Before I put in a wired network, I even managed to get this to stream 24/192 from a NAS over WiFi. I would always try this before resorting to Ethernet over mains. 

Hi

I'm using an Asus router wired to a separate Asus access point (very long home) which connects to a Qb over wifi and had the same problem. As it turns out, the problem was easily fixed with some router settings which relate to how AirPlay (or specifically bonjour) works with the routers multicast settings for the lan and wifi. These are what I changed. Number 1 was most important but two and three sped up the discovery  

1. Turn on IGMP snooping on your wifi. You might need to do this on both the 2.4ghz and 5ghz bands. On Asus systems this setting is under wifi -> professional

2. Turn on:

Multicast routing (IGMP proxy). found under LAN -> IPTV

Enable efficient multicast forwarding. Found in the same menu. This option might be knows as multicast - unicast on Cisco routers

good luck!
