iPhone NStream dropout

I use n-stream on an iPhone 5s and an iPad Air. It all works fine all the time. The iPhone needs to see a good strong wifi signal (I find it is less sensitive than the iPad) but once you move it back into a strong signal place, it searches for a few seconds and then it sees my streamers with no problem.

You could try resetting the n-stream app on the iPhone. Or you could delete it completely (by holding the icon until they all wobble and then touch the cross in the corner, press the home button to cancel the wobbling) and then re-download the app.

Because it works on the iPad, it seems likely not to be the NDX, otherwise I would suggest making sure you have the latest firmware on the NDX as that improves discovery and also resetting the NDX to the factory settings.

I have also found that discovery doesn't always work properly when you use the switch in a low cost commercial router (although I haven't used a BT hub.) There are multiple threads in the forum which suggest connecting everything to a cheap switch, like a Netgear GS105, and connecting that as the only thing going back to the router.  But the fact that it works on your iPad all the time and often not on your iPhone is odd as both will be connecting back to your router by wifi.

Also again I don't see that it should be different between iPhone and iPad but nevertheless I would use Ethernet rather than wifi to connect your NDX back to your router.

Lastly you say rebooting your NDX allows your iPhone to see it.  In that situation where the iPhone can't see the NDX, does rebooting your iPhone also sort it out I wonder? And if it does, does restarting the app (rather than deleting or resetting it as I suggested earlier) find the NDX?

By the way, you should be using the naim app, not n-stream, which has been long superseded. All my previous comments refer to the naim app.

Thanks David, I only see 2 Apps in the App Store, Nserve and the one I use which is shown as 'Naim' which I believed was known as Nstream. Have tried resetting everything, including removing and reinstalling App but makes no difference unless I re-boot NDX and then it appears and remains for a day or so before dropping out. 

So you are saying that the iPad always works, and that the NDX can always see the upnp server? If so, the network sounds fine, and it has to be something to do with your iPhone. Do you have loads and loads of pages open, which are exhausting its memory? Try double clicking the home button, and swiping everything off the screen apart from the Naim app. Then give it a day and see if it still works. 

Update, re-booted NDX and as previous the Naim App sees NDX on opening. Close App reopen no issues. Open IPad, it sees as normal but by doing so has immediately knocked out the IPhone, i.e. Close IPad and now IPhone can no longer see App. I guess it must be something to do with the signal being accessed by both devices concurrently knocks out the IPhone. Have tried closing pages/applications but to no avail. If I wish to see App on IPhone I must reboot NDX!

You can't access a Naim streamer from two IOS devices at the same time, but normally it's enough to close one for the other to then be able to find the streamer.  As I mentioned before I use an iPad Air and an iPhone 5S interchangeably and shutting one to starting another takes only a few seconds while the second one finds the room.  I wonder whether closing your iPad is actually stopping it from the process of accessing the streamer.

So try this.  Open your iPad, access the naim app and do something to the streamer. Then close the app by double-clicking the home button and swiping the app upwards.  Then close your iPad and try your iPhone. I bet it will be fine.

My logic is that when you reboot the NDX, it disconnects from the iPad and so your iPhone can then connect fine.  If the above suggestion works then we just need to work out why your iPad isn't relinquishing the Naim app on closure.

Yes naim is the new name for n-stream by the way.

Just turning the iPad off should do the trick. As soon as mine turns off (by closing the Smart Cover) I can access the 272 from my iPhone. Did you try closing all the open pages on the phone?

Hey David, you guessed right.  iPad closed, swiped away and IPhone works fine.  Many thanks for this, enjoy your evening - Nik

Good.  But as HungryHalibut says, shutting the Smart Cover on the iPad (which is what I do) or pressing the button on the edge briefly (not the home button, but the main power on/off button on the edge of the case at the opposite end to the home button) should make the iPad screen go blank and disconnect the Naim app without you having to swipe it.  How are you shutting the iPad down? Perhaps you have the stay awake settings too high?

Hmm, did not use IPad at all last night, only iPhone to check consistency. Upon arrival at home this evening IPhone not seeing NDX again. Tried all the closing etc but to no avail. Something is forcing the iPhone to lose visibility.

What UPnP are you using,   Synology's Media Server or Minimserver ?

Right. If you turn your iPad off altogether ( or turn off wifi on your iPad so it can't be on the network) then does your iPhone find your NDX? It should do.

So here's another thought which is a bit off the wall, but easily checked. If you go to settings in your naim app on your iPad, by selecting the naim app, selecting NDX and then tapping on the gear wheel icon, you will see a list of options. Go to "other settings" and check that "stay connected" is unchecked.

My thinking is that your naim app on your iPad is very unwilling to disconnect from your streamer. Perhaps this is why?

Checked options on IPad, the 'stay connected' not checked. Turned off wifi IPhone still cannot see. Will try 'stay connected' on the IPhone this evening to see if that makes any difference. I will get to the bottom of this - hopefully!

So if it isn't the iPad holding onto the control of the NDX, which it can't be if your iPad has its wifi turned off because as far as the NDX is concerned, the iPad has ceased to exist, then it must be something about the iPhone and the way it connects to the NDX.

So another test. If you are in the situation where your iPhone can't see the NDX ("no rooms found"), what happens if you reboot your home hub 4 rather than your NDX? Also in that same situation where your iPhone can't find the NDX, you could try unplugging the NDX network lead and plugging it in again, which I suppose might make the NDX ask for a new lease from the DHCP server in the HH4.

i don't think this is anything to do with what upnp server you are running because that is nothing to do with the naim app. It should still find the NDX even if there is no upnp server because you may be wanting to control something else like switch to another input.

i also don't think this is down to too many open apps on your iPhone because IOS is pretty good at making room for the current app by closing unused apps itself and in any case if you swipe an app and then re-select it, IOS will definitely give it space. For very space-consuming apps, like photo-editing or HD image review, this can get flaky, but the naim app isn't one of those.

i suspect that you are going to soon want to try putting a simple unmanaged switch like the Netgear GS105 between your NDX and your HH4. This solved a problem for me of my laptop constantly failing to find my network printer. This wasn't with a HH4 but consumer wifi routers do often seem to have weird connection and discovery problems.

Ladt thought for now: there is s very useful posting from Phil Harris on network discovery issues in the sticky threads at the top of this forum. It is well worth reading if you haven't already and he has some things to try there.

If that was checked & helps with the problem,  then open "Device List",  make sure the list header "Enable" is checked & then check each (& only) devices that you want to have access to your network player.

OK one thing to try ......... & it might not be the problem,  but it was my problem when my iPad had trouble locking on to the system

Open Synology web page

Open Media Server > DMA Compatability > make sure "Restrict access to newly detected UPnP/DLNA devices" is un-checked 

If that was checked & helps with the problem,  then open "Device List",  make sure the list header "Enable" is checked & then check each (& only) devices that you want to have access to your network play

Ok, tried re-setting Home Hub and now once back up and running the IPad and IPhone unable to connect 'no rooms found'. Reboot NDX and hey presto immediately sees NDX. Do you think it may be a setting within Home Hub that is corrupting? Just ran a further test IPhone started first, sees NDX first time. Close iPhone and swipe away. iPad now cannot see NDX now. Seems first in the queue will not allow the second in, if that makes sense.

Mike, thanks. Tried that, in checked but went into device list and could see NStream with 2 separate addresses which I assume represent both the IPad and phone. Tried to screen shot and paste but could not accomplish that to show you.

All very weird.  Yes that does make sense. The NDX seems to be hanging on to the IOS device it last saw.  I can't remember whether you already said, but did you try resetting the NDX to factory settings? (Ie via the spanner icon on the remote).

David, have reset NDX to factory settings and for now seems to have corrected, hopefully that was the cause - hopefully! Thanks so much for your help and the other contributors 

Excellent. I will keep my fingers crossed!
