Naim App NDX Connection Problems

Posted by: mackb3 on 01 June 2015

Persistent problem with the Naim App not finding the NDX requires resets. Just don't have issues like this with SONOS Connect (mainly for Deezer) to the NDX. My network is stable with modem/switch/NAS/NDX/oppo etc... all wired with Blue Jeans Cable CAT6 tested Ethernet. I'm discussing with my dealer but thought I would throw it to the forum. Now, I've recently had issues with my UnitiServe but this should have no bearing on the App coming up blank. I use iPhone 6 and iPad Air2 to connect. The modem is Aris from Time Warner Cable which has dual band wireless.

Assuming its not this way already,  I would first switch everything to DHCP (automatic) IP Address management. This management function resides in your wireless router/hub & the NDX & NAS should also be set for DHCP. 

Switch everything off - wait 2 minutes - then power up in the following order

Router - wait 2 mins

NAS - wait until its fully running

NDX

Switch

- make sure the NDX can see the network.

Finally the Naim app  

 

If that doesn't work,  does the NDX see the network & play OK from the front panel & remote 

If so you most likely have a wireless router issue

+1 I do this full restart occasionally, perhaps every 3 months, and it seems to make my whole network behave, including music, phones, computers, printers etc. I leave everything on DHCP, except for my Unitiserve, which the streamer seems to find more quickly and reliably if it had a fixed address.

This is the order I usually follow just doesn't stay. I just replaced the modem with a brand new one Saturday but same issues were prevelant with the previous one. NDX is DHCP and had to reinitialize the NDX to find the network. I'll have to login to the modem and NAS to check DHCP.

My fingers are crossed for you. Hopefully that will work and you can forget about everything but the music.

 

But DHCP is not a requirement and unless you have a IP conflict with something else on the network, DHCP should't change the problem. Once each device gets its IP, subnet and DNS settings assigned over DHCP, the rest of the traffic is the same as when using a static address (i.e. DHCP is out of the picture about 1 minute after device startup until the DHCP lease expires and it has to recheck with the router).

 

I use a fixed IP for my NDX but DHCP for the iPhone using the Naim app and have never seen a connection problem in 2 years.

 

If you still don't have luck, you can install a free app called Fing to scan the home network and confirm whether the NDX is actually visible on the network and even issue a sequence of pings to check for packet loss between the iPhone and NDX (assuming Fing finds the NDX so you can see the IP address it got from DHCP). About 1000 tries should give a good indication since it probably takes about 30 mins to complete. On a home network I would expect 0% loss and sub milisecond latency.

Having fixed IP Addresses is OK - ideal in fact - but it can have issues caused by user setup errors that can make network discovery a problem. 

Going to DHCP in a simple basic home network is how all simple home networks are designed -  its going back to basics & is keeping it simple (KIS) 

Once Mack has it sorted with DHCP, then play with fixed IP,  meanwhile KIS

Yup I would agree with that 100%.

 

Actually, this could be the problem. 99% sure that any home router will be DHCP enabled out of the box. If you have DHCP enabled on the whole subnet but tried to assign a fixed IP anyway, this could stuff things up.

Thank guys. I have heard that a static address can be good and problematic but at this point matters not. Something to work with this weekend. Don't have a clue how to do it though.

I hate to break these news to you, but most consumer-grade routers are nests of bugs. The best money I spent recently was on a Ubiquiti EdgeRouter (https://www.ubnt.com/edgemax/edgerouter-poe/) and a separate Ubiquiti WiFi AP. They take more work to configure than consumer-grade stuff, but you can control your network configuration very precisely, including firewall, bridging, NAT, and DHCP. Fixed IP addresses and DHCP coexist without clashes. I gave fixed IPs to all of the permanent gear (Synology NAS, several UPnP renderers -- naim, Oppo, SOtM) and I leave mobile devices and laptops on DHCP. Everything always finds everything.

Sorry if you said it above I missed it, as I am typing mobile. But connectivity means several things, and if the Naim app can't see the NDX assuming DHCP is up and running, then it points to the multicast discovery being blocked by something in your network.
Therefore I advise connecting you NDX to a switch, along with everything else. Now use a media friendly wifi access point such as an Apple Sirport Express and connect this to the switch,
With this setup, if router also on the switch is providing the DHCP service, then your Naim app should see the NDX.
There is a special IP address on your network you can ping to check discovery is working on your LAN for the connected devices..
Simon

Edit: the address to ping  239.255.255.250
Ping that and you should see all upnp discovery enabled devices return with their IP addresses  if the LAN is not blocking them

Fernando,

 

These look awesome. So... feed from modem then feed devices direct like a switch or feed gigabit switches from each port and one of their wireless devices.

My setup is as follows. EdgeRouter PoE-5 connected to cable modem downstairs by a short Cat-5 cable. EdgeRouter port 2cconnects to a 1Gb switch that feeds NAS, UnitiQute, and Oppo BDP-103. Port 1 has a longer Cat-6 carrying net and power to the WiFi AP centrally located in the house. The AP has a bridging port, from which I run Cat-6 to a 1Gb switch upstairs where I connect a UPnP/DLNA renderer (SOtM sMS-100) and whatever else I want wired there. The EdgeRouter is most easily configured by connecting a computer to port 0 and using the browser-based configuration app (first thing to do is to update router firmware if needed). With up-to-date firmware, the configuration app offers a set of configurations wizards, including the simplest SOHO "home office" wizard that has reasonable initial firewall and NAT settings. Using the app, I gave fixed IPs to the fixed gear, letting DNS use other IPs freely for mobile devices. The AP requires a separate Java app for configuration, which is a bit of a pain, but after that's organized, it's very simple.

I'm not sure if this will help but 've been having similar issues "No Network. Press List To Re-Try". I have an Apple AirPort Extreme (not the current version but the lower profile one). I have found changing the wireless channel(s) from Auto to a user designated has certainly improved the reliability of the connection.

Wat I chucked at your post.. Honestly discussing with a CCIE engineer the matters we raise here is like asking Einstein to calculate 7 x 7 ...

The vast majority I suspect have no problems, the issues start when cheap, less reliable low end consumer devices, connectivity options or short cuts are used, you do need a little knowledge to understand why or if it's not working properly. (That includes hifi devices, one such device discussed on thois forum has to use a gigabit switch to function correctly.. That sounds appalling)

 

My advice, set up your LAN properly using wired connections with regular consumer switch devices and you should be fine.

Keep wifi and Powerline adapters to a minimum and try and avoid other than for control point. Try and keep the control point wifi seperate from most other things.

Dont use the switch ports on your broadband router for switching your LAN.

Follow that and you should be ok.

 

Now even for an entry CCENT that is a stroll in a park.....

Exactly the same issue here. Returned today from and 26 hour 10 state round the clock trip with my daughter from Wyoming to North Carolina and NDX was locked up again. Restart NDX and it gets it's IP again. Just a process that I hope to remedy.

 

So is this set up via the Air Port utility?

I used to experience my NDX becoming unresponsive like this and requiring a restart from time to time and I think it was an issue with the NDX or NDX firmware. I currently have beta firmware installed, and so far I have yet see to this issue re occur. Other than that I can't talk about the beta firmware on the forum.

Correct.
