Naim App Wifi Problems

Might be worth getting rid of the static IP address and reverting to DHCP.  With the various improvements Naim have made in the streamer firmware and app, you may find that works fine now.

Thanks - I've tried that, things work for a few hours and then the Naim App can no longer find the ND5 XS.

There are so many variables with this. You have establish your app works some of the time, so have you tried deleting the app and reinstalling it? Could it be your wireless hub that is playing up? and have you reapplied the firmware update?

Thanks for the suggestions.

I haven't tried deleting the Naim App and reinstalling it as I will lose my playlists if I do that.

I haven't tried re-installing the same ND5 XS firmware version again as I wasn't aware you could do that and the installation completed successfully anyway.

I don't believe the problem lies with my wireless access point or router as I can stream images, music and video to the TV and iPad/iPhone without problems.

Of all the devices connected to the LAN, the ND5 XS is the only device that does not respond to a network ping 100% of the time.

In that case is it the obvious....your ND5 XS is the issue. Is there no way you can either run a long length of Cat5 cable from your router to the streamer, or do as I have done and use a Devolo Powerline Adapter - http://www.devolo.com/uk/Produ...N-Powerline-adapters.

Some Naim users do not like using them at all, because it degrades the sound quality, personally to my ears I could not tell the difference especially as my Streamer and UnitiServe are all on the same rack and are using a local hub to transfer the 1's and 0's.

As a test I moved the ND5 XS to the spare room and connected it to the router by a cable for a day or so and things worked fine - this was with the previous version of firmware and two versions ago of the Naim App.

You're correct in that I could use a power line network adapter, but it says on the box that the ND5 XS works via WiFi so it should work

Since (sometimes) I can use the PlugPlayer App to control the ND5 XS when the Naim App cannot find it, there may be a problem with both ND5 XS and the Naim App.

Don't forget, there are a lot of thing that can stop WiFi responding quickly enough, to name but two:

RF band congestion (too many people using WiFi in the local area)

DoS attacks on your router if you internet connection and WiFi are on the same device (this is more common than you may think - currently mine is under attack but resisting valiantly).

Thanks, I have.

With the previous firmware, I would see that bonjour services on the ND5 XS would stop appearing at +/- the time the Naim App lost communications.

With the latest firmware, I'm not sure if bonjour services are still used or not.

I just ran a network scan and the ND5 XS does not show at all, even though it is playing from my NAS

I'm not sure if that's what you meant by "Internet connection and WiFi are on the same device", but my wireless access point and router are two different boxes.

When I moved in here, I scanned the various wireless frequencies and chose one that nobody was using at the time. Of course this could have changed, but then it would affect streaming on the iPad and TV, which it doesn't.

I just switched the ND5 XS off and on again to re-establish communication with the Naim App.

Now the network scanner shows the ND5 XS with "P" against it (with the old firmware it showed "BUP").

The router has "GUP" against it and the WAP "BUP".

Where  "P" = pingable, "B" = bonjour, "U" = UPnP/DLNA, "G" = gateway

If it all worked OK with the previous version of the app, and you've done all the usual things like powering everything off and on again, I suggest you drop a line to Naim support as it's possible you've found a bug in the new version.

Seems unlikely that there is something wrong with the streamer.

Line dropped to Naim Support.

Hi,

Yes, the ND5XS works via WiFi but if the WiFi signal (or some other part of the infrastructure) isn't stable enough then it will have issues... Basically you need to narrow down where the problem is coming from. 

I would suggest as a first port of call that you *TEMPORARILY* connect your ND5XS to your router via a direct Ethernet cable connection and then see if that resolves the issue. (As it's the ND5XS that seems to be vanishing - you say it doesn't respond to pings - then it seems that that is more likely to be the location of the issue rather than the app).

When you say that it disappears and doesn't respond to pings then have you tried controlling the ND5XS via the hand held remote and accessing Internet Radio or UPnP?

Right now I'm suspecting an issue with Bonjour traffic being dropped by your router but you really do need to get more information...

Cheers

We've not come across any general new bugs in the latest firmware release so if there is something there in the app (or the firmware) then it's likely to be a combinational thing along with the OP's network / hardware ... again, we need to get some basic faultfinding out of teh way before any conclusions can be jumped on.

Cheers

...just be aware that Ethernet over mains devices *CAN* be just as susceptible to noise and general flakiness as WiFi (and the E.O.M. adapters themselves have to support the protocols to be able to pass them through).

We see so many installations that *GENERALLY* you get a feeling for issues fairly quickly and in this case I'd like the OP to try a couple of things to start to prove through where the issue is and hence how best to solve it ...

Coincidentally I was setting up a network link between an annexe (a converted garage) and the main house last night, even though they are part of the same structure we could only use WiFi if the wireless bridge was placed in a window (foil backed insulation in the walls killed any WiFi) and I had to resort to trying Ethernet over mains ... from one socket on the annexe ring I was getting a consistent 50meg (signalling speed - actual throughput is obviously less) and from the *NEXT* socket on the annexe ring I was getting varying rates between >100meg and <20meg ...

Phil,

I agree with your suspicion of the router or the WAP dropping Bonjour traffic: I have similar issues and that was my conclusion for my system (I didn't trouble you, as it's my router therefore my issue to resolve!).  My system is hard wired Ethernet with a switch isolating the NAS <> ND5 trafic from the Wireless Broadband Router.

I do have an odd couple of things though, and as they're less troublesome 'juanito' may have the same issue but be thinking it's unimportant in comparison.  If so we have the same underlying issue.

First

When playing a playlist downloaded to the ND5 XS (e.g. after clicking the first track of a whole album), the system will play a few tracks OK, but then, sometimes, it will...

play the first 2 seconds of the next track

play the last 2 seconds of the previous track (usually silence)

then continue playing the next track OK.

It's interesting to note that most times when it does this, the playlist UI Naim app (Android) will briefly flick up to the previous track as this happens.

This issue generally only occurs after:

1  the app has had difficulty reconnecting to the ND5

2  the app has had difficulty finding the UPnP media server

3  the ND5, the WAP or the NAS has been rebooted

I'm not too bothered as clearing a forced restart of the Android app will usually clear the problem.

Second:

The other issue is that whenever metadata presented by the Media Server is changed (N.B. no problem adding new items), I have to clear the App's data through the settings or that item in the browse list reports "No Items".  This implies that the App is inappropriately caching the browse lists without an automatic refresh when conflicting information is found.

Yes, when I connect the ND5 XS to the router via a cable, the problem seems to disappear.

When the Naim App loses communication, I can access both the NAS and IRadio via the front panel/remote control.

The above being said, I have an iPad, iPhone and TV connected via WiFi and they stream without problems via the PlugPlay App

I'm hesitant to jump in to the thread in case I confuse things. However this does sound like an issue I get very occasionally with current firmware, and a lot more with the previous firmware version. So this may help Phil H.

Basically the (in my case 272) seems to loose the network, and neither the remote control (iRadio) or app can get it going. Sometimes after about five minutes it may suddenly come to life. Usually I have to turn the XPS off and on again to reboot the 272, this so far has always cured it immediately finding the network without having to re-enter any details.

My network is a single Apple Timecapsule , current OS is El Capitan on iMac, naim app is up to date as well.

Regards.

Hi,

If your 272 is going unresponsive to the IR remote too (and requiring power cycling) then that's sounding like a very different issue ... the OP's unit remains responsive to the IR remote and can still browse and play UPnP / Internet Radio etc. so isn't showing those symptoms.

Cheers

Cool - so I am now pretty sure that it's a network / router related issue with the propagation of Bonjour ... 

I don't suppose you would have a different router that you could just set up as a test (it doesn't have to have an internet connection unless you want Internet Radio while testing)...

Cheers

Phil

Hmmmm ... What UPnP server are you using on what brand of NAS? I'm sensing a delicate hint of UPnP server here and maybe it would be an idea to throw MinimServer or Asset UPnP on a computer on your network, point that at your music on your NAS and then see if you get the same issues when using Asset / Minim as your UPnP server.

Are you a Windows or an OSX person? (This question appears to be the modern day equivalent of "Are you a dog person or a cat person?")

Cheers

Phil

I'm not so sure it's a router related bonjour issue, my printer is discovered via bonjour by various iPad, iPhone, mac, etc without problems. Also I thought the latest firmware/App moved away from bonjour?

Sorry, but I don't have a different router to try (mine is a Cisco RVS4000).

Hi Phil,  answers in order...

Synology Media Server (on a Synology!!!)

Yes I'll try that, but it'll have to wait a month or two as I'm otherwise occupied at the moment.  It's not critical as I have a work around that keeps it going for quite some time and then, during that time, it doesn't skip a beat.

Thanks

Just to clarify, my problem is uniquely that of losing communications between the NDS XS and the Naim App.

I have not had problems with the ND5 XS not being able to find the NAS/media server or iRadio and, even when communications with the Naim App are lost, the ND5 XS will continue to play from the Naim App playlist.
