More networking help please

It would be helpful to get a description (diagram) of your network,  media server & control point.    For simple home audio with these kind of issues its advisable to not have discrete IP addresses & revert back to all DCHP.   It's OK to "reserve" an IP within the ISP DHCP licence range numbers, but it can be a bad place if you do have a conflict so better avoid the possibility & go all DCHP.  

Virgin Superhub 2 (Modem Only Mode) > Netgear RT650 (new) > Netgear GS810 Gigabit Switch (new) > Cat6 (all new) to Synology DS212j/Linn MDSM/Superuniti/iMac

iPhones etc all connected wirelessly.

That's it - nothing else to complicate it.

It's very odd that the Linn just works and the Naim doesn't. Your setup is just like mine - virgin hub in modem mode, Asus router and then the streamer and NAS connected to a Netgear switch. It just works happily, with reserved IP addresses for the streamer and NAS. Phil Harris did a long post about network discovery stuff, bonjour and the like, and I wonder if it's something to do with that. 

Paul, the fact it all works until you try and navigate in UPnP suggests to me it's not a network issue, but perhaps some issue between the SU and the UPnP media server.. Which media server are you using?

But I would check the subnet setting, gateway address and definitly the DNS addresses are  set correctly on the SU if you are doing this manually... as well as on the NAS.. which is why it genereally better to use DHCP so all this taken care of for you..

Per my 1st post,  I would go back to all DHCP & start the diagnostics from there.    

I am utterly baffled as well.  I too have reserved IP addresses for all those devices.  

In terms of Phil's post the Synology, Linn, Naim, Netgear and iMac are all broadcasting Bonjour.  Surprisingly the iPhone(s) don't and I don't know why but the issue is not discovery by the iPhones - they connect and control the SU perfectly using the Naim app so that's not an issue.

There's 'something' that the Naim devices I have/have had clearly do not like.  For the record a Marantz streaming setup also worked flawlessly so it would appear that there's something in the Naim/network configuration that's amiss.

As an aside - what a piece of kit the SU is!  The reason I wanted to try it was because I didn't feel the Linn alone was doing my speakers justice (Kudos Cardea Super 20's) so it's either a SU or the Linn + Nord Hypex.

Mike - you mean remove the static IP's?

Paul - can you please check your network settings on the Super Uniti? Make sure that in the Network Settings, DHCP is set to YES.

If it's a unit that worked on a different network, it may be advisible to restore it to factory settings and reconfigure it to your network again. Make sure it's connected via CAT cable.

Another thing - can you try swapping the CAT cables between LINN and NAIM streamers? What you describe may also be caused by a faulty CAT cable.

Synology Media Server DSM6 point something (up to date).  I like it and it works fine.

Yes, but there is more to manually setting than just setting the IP addresses.. You need to correctly set the  gateway and DNS addresses as well as subnet as well if not using DHCP.

as you say the error occurs when you try and navigate it feels UPnP config related or bad addressing. Are you able to confirm these address types are all set up correctly on the SU if you can't enable DHCP?

Thanks - DCHP is 'Yes' and I have definitely tried the other suggestions you mention.  No joy.  Interestingly the issue seems ONLY to arise when using the remote.  The app is pretty flawless, even when the remote doesn't work.  Just discovered that by accident.

Yes   ..............  set all the Naim. Linn & NAS to DHCP & the same on the router,  then power off & restart it all beginning with modem/router,  let it complete its full start process,  then one at a time with the other units. 

Alarmed by your comment that it only happens with the remote & not app !!!!   Thats a whole new problem !!!!

There is one more thing, which for a life of me I cannot understand.It may be happening to Paul as well.
As evident from my profile I run 4 NAIM streamers. The only other networked equipment is computer based (Apple Macs / iPads and a printer).

On some odd occasions, whenever I tried connecting a different streaming device (e.g. Yamaha streamer, Oppo 105) via a wired network, streamign to NAIM got somewhat interrupted. It happened several times. Disconnecting the non-Naim equipment restored the ballance. I know it makes no sense from a network point of view but it happened.

My suggestion Paul is that you try to disconnect your LINN altogeher and keep it off the network for some time (for the switch to refresh). Your network may have the same ghost as mine and only likes Naims

Ok done all that.  Router set to DCHP.  Router switched off along with everything else and then router rebooted and NAS, Linn and Naim in that order.

On selecting UPnP on the SU I got the same error message from the start this time. Then again with the app it will work no issue and after a period of time the remote operation works too.  Untill I switch sources and then try to switch back again.

Adam - take your point about another network player concurrently.  I'll try it but bear in mind that this very same issue blighted me when I ONLY had a UQ2 running - no Linn.

I'm now alarmed. This seems to be pointing to a probelm which I have not seen before. And the culprit seems to be the SU.

Have you tried performing a factory reset on it?

Paul - have you tried a wireless connection from the SU? If not please disconnect the CAT network cable and connect it only via WiFi and report back. I want to check one thing....

I haven't and that's the logical next step which I'll do tomorrow.  Am more than a bit gutted as I wanted to exorcise the ghosts of UQ2.  Unless I get to the bottom of this then I will be saying thank you to its owner and ordering something else to complement the MDSMs obvious weakness - its amplification.

Still, at least I've become a rare breed in being someone who actually REALLY compared them both side by side for the inevitable next 'Linn vs Naim' thread.

I agree, that is next on the suspect list I am afraid...

OK.

I still think there is something odd on your wired LAN... that is causing those issues. Hence my wi-fi only suggestion just to check if the discovery works well.

I'm signing off for the night - look forward to your update tomorrow.

Night night

Morning and thanks for all the help last night.

Purely by accident this morning I spotted that the firmware on the SU is NOT running 4.4.  As the guy who I borrowed it from is a bigger technophobe than me he has asked me to update it so am having a go but....as ever...seem to be running into some issues.  Basically I am using the USB update and have the updater package installed and have also installed the USB driver on my MacBook and it's showing as:

CP2012 USB to UART Bridge Controller.

Have restarted the MacBook and SU after installation.

The issue is that when I run the updater the USB port is not showing in the dropdown box for which port I want to use - all I can see is the bluetooth port.

I don't know whether the firmware may be contributing to the issue I am experiencing but it's worth my doing anyway to at least rule it out.

Any ideas as to how i can get past the USB issue?

Thanks again for the help.

Paul - not all USB cables are equal. Some, used for charging, will not work as they are wired somewhat differently. 

That may be a source of your problem. 

OK Adam - I'll whizz to get a definitive data cable and revert later this evening.

Are you saying that everything works ok when you use the App? Can you play what you want and switch between sources every time with no issues? If so, the network is fine and it's an issue with the SU and how it's responding to the remote. 

Exactly HH.

Paul - I was thinking - you should be able to see the USB port on your Mac, once you've completed the instalation of the UART bridge controller. Even without a USB cable.

Can you send me a screenshot (email is in my profile)? I seem to remember that the port was named counterintuitively.....
