No Rooms found

Have you tried killing the app and restarting it? It usually works. 

I have had the same problem a couple of times recently and did the usual turn things off and on starting with my NDS and progressing through the network items - even resorting to deleting and reinstalling the Naim app. Things return to normal sometimes quickly, sometimes less quickly.

I would like to know what causes this problem and if it can be avoided or at least what the quickest fix is.

If anyone from Naim is on, maybe you can advise. May of course just be 'tinternet or issues with a LAN but the error appears to be random.

"No Rooms found" in my experience is due to network problems from my internet modem/ router or internet extender playing up. It has been more of an issue since we changed internet providers. I have found turning off the internet switch and Internet wireless extender boxes solves the issue. Makes you pine for the simplicity of CDs and LPs!

I get this like others. As ever it's only naim kit/app that's affected. My two chromecast aren't. The two wifi speakers (Bose and Philips) never are. My Squeezebox never was. The two Amazon TV devices are always fine. Everything else on home network, once on, stays on. But the Muso, the 272 and the Naim app are still a regular pita. Why is this? Surely they could sort it out by now? I mean this is years and I'm fed up excusing them.

It's a real shame as the NDX sounds brillant all of my Naim amps and preamp have never missed a beat over the years.

My NDX has been faultless.  I admit to having seen 'No Rooms Found'  but I've always found that to be an app problem, not NDX.  But so long time ago & I really can't be sure what I did to fix it,  it was probably a delete & reinstall the app or the old turn it all off & back on again.    Its obviously a network problem & I'm tempted to go back to basics & run a sequential restart.  Basics first,  is the broadband hub & all your bits set for DHCP (automatic IP address mngt),  if not it needs to be.   The sequential restart is turn it all off & leave it off for 5 minutes.   Then restart in the following order:   1. Wireless router - let it fully complete its start process.    2. Switch.    3. NAS - let it complete its start process.    4. NDX ..... it should find the network automatically but may need some manual help with the front panel buttons.      5. Control Device – in some cases of network discovery problems it might be beneficial to reset or even delete & reinstall the app.       ...............   If that doesnt work you have better tell us in detail what your network looks like, hub make/model,  wired with & too/from  etc    

I have done all the above all set to HDCP , resets done as you describe the only thing I haven't done are the switches I will do those tomorrow thanks for help.

I think the no rooms found is caused by some consumer network equipment temporarily getting screwed up handling the UPnP discovery multicast datagrams. 

My solution was to use more commercial equipment which better handles multicast and reliably handles IGMP as well as setting an IGMP querier on a managed switch for my local network - all my multicast discovery apps (not just Naim) now work flawlessly. The only time I have seen No Room Found recently was when I accidentally ran my Naim iPhone app on 4G as opposed to wifi.

I don't think you need to reset the switch,  it you leave a GS105 connected for long enough & it will relearn its LAN partners.  The main thing is the sequence restart with a reset broadband router so its DHCP assigns IP addresses.    I would be inclined to focus on the app,  do you have the latest version & is it iOS or Android?  Have you tried deleting the app & re-installing ??  and what make/model is your broadband hub.

I have felt your pain myself before (and even a little bit recently after a power outage) and while the other network sages here are the ones to listen to, all I can offer is empathy.

As Jamie says above, and it is true at my house, Naim stuff is the ONLY out of many network attached items that gives this kind of grief, although I must say lately for me it has been much better, albeit not flawless.

AT LAST after shutting everything down for the 3rd time and unplugging switches not the Netgear I have again got my music back !!!!!! It's such an awful problem every time  sit down to listen to music am never sure if it will work.....Thanks to every one for all the help didn't feel it was only my problem and alone with it. One more question does any one switch off the Streamer if your not using if for a few days ? Huge thanks again.

I always leave Naim streamers on all the time. You shouldn't need to turn them off unless an electrical storm is expected.....

Thanks David I use to turn it off thinking it might help with Internet connection but will leave on from now on.

I'm having this problem tonight after a few weeks of solid connections. The irony is that on the same iphone the Spotify app has no problem finding my streamer and taking control of it. The Naim's effort limply gives up the chase and suggests that I buy a Muso so that it can have a go at connecting to that instead.

This suggests to me that a lot of blame directed networking issues is misplaced. 

I am the same will work well then you settle down to have a music night and out of the blue No Rooms but my iPhone couldn't get connected either and Spotify and Tidal the same. It's a marvellous sound when it works but your hearts in your mouth when you tap the Naim app to see if it works. Really annoying, the other bug bearer is that you have to go to the Naim web site to look for up dates it doesn't do it automatically .

BTW as this looks like home network consumer device issue related...  there is a possibility you have a below par wifi unit on your broadband router... (I think so many issues are caused by this) ... it might be worth logging into your broadband router to see if it has an 'IGMP snooping' feature on it... if so switch it OFF .. you might then find visibility across your consumer home network devices improves, and so your Naim app and Naim clients don't get starved of discovery data.

Down side would be your network and wifi data could get more cluttered, but for a small home network it's a small price to pay.

BTW the term needs to be 'IGMP snooping' and not 'IGMP proxy'  or anything else, those are different functions.

if there is no IGMP snooping function, and it's a relatively recent unit, it might be hardwired to on.. so you might want to temporarily replace to see if things improve. If there is an issue here it won't just be Naim suffering, but things like printer discovery etc might become unreliable too.

For the record, IGMP snooping on my Cisco and UniFi devices works fine .. and my Naim kit are happy chappies. IGMP snooping on my Apple Airport Express was temperamental, causing visibility issues (room not found etc) from time to time, I disabled it on the Apple.

I've had this happen to me several times. I eventually learned to fix it by shutting off WiFi on my iPhone, waiting a few seconds, and then turning of WiFi on my phone. This always fixes the problem.

S-i-S gives very sage advice.

I have an ISP supplied Hauwei broadband router and I isolate my audio components using a separate switch (Netgear GS105), but I still needed to turn off IGMP snooping in my router.  Before that the Naim app wouldn't find my streamer with any degree of consistency, now it only misses when I've restarted one or other network device and I've not allowed a minute or two for them to sort themselves out again.

This was on advice from Simon:  We're lucky to have him, he's an out and out networks expert!

S-I-S, I have just got the dreaded no rooms found message again. I have a BT Home Hub 5 and have logged into it set the IGMP Snooping to off but I can't see such a setting even in the advanced settings. Would the HH5 have such a setting and if so where is it likely to be buried in the menus?

I have a Cisco switch similar to yours and you say the issue is unlikely to be there so I suspect my HH5

Any help would be greatly appreciated.

I would say it's the router . I have the BT 6 and it's not great. Am going to get a Linksys EA 7500 which comes recommend by those those in the know.

Hi Nigel,  BT hubs don't have any IGMP adjustment facility.       I too have the BT HH5 & have never had a no rooms message other than caused by 'operator error' & resolved very quickly.  I have to say my HH5 has been rock solid.  

  Interesting comment by  Veronica that the BT HH6 (Smart Hub) is not great;  oh well I'll have to wait & see as I have one coming in a few weeks.    

Thanks Mike.

This is clearly an issue that doesn't seem to be going away and appears to afflict Naim network devices more compared to other manufacturers. That might be unfair and the observation is only based on issues and comments made on this forum.

If anyone at Naim has any ideas as to the route cause of the No Rooms Found issue it would be helpful to hear from them. It may of course be down to individual networks and the devices on those networks and the way a particular network has been implemented. But this issue has been going on for so long now, I would have hoped that someone at Naim might have noticed a pattern or some commonality when the issue is referred to them.

I know I could approach Naim customer services but I also know the issue will resolve itself by the time I do with various switching off and on of various network devices and deleting and reinstalling of the app. I also know that it is very likely to reappear again so it would be nice if there is some generic advice available relating to local networks that might remove (or al least diminish) this issue.

Yes Mike my Hub5 was solid as well the 6 drops connection a lot the flashing purple light means it's not getting a signal. Can be down for days have tried everything on the phone to BT not much help then it comes back to life. A lot on the forums about this problem.

Mike, I wouldn't throw out your HH5 quite yet!

Veronica, when I have had problems with BT Home Hubs in the past, BT have just sent me another. Try insisting they do the same for you. It must be cheaper for them in the long run unless there is a generic problem with the HH6.

I find it so much easier to run my own LAN hardware inside of the ISP supplied router, on which I simply disable WiFi and connect to my own device with a short Cat5e cable. Then they can give me whatever piece of junk they like, and as long as it gives me an internet connection, I don't worry about its other abilities.
