Stuttering Playback

Odd that the switch would throttle the speed so much as to make an audio signal cut out. I never had that problem with a GS105 when I had one. Gigabit speeds are way more than you need for even hi-res streaming. The NDX only runs 100Mb.

Now I have one remaining question: Why does one of the lights on the right side of the Ethernet port on the NDX glow orange instead of green like every other device known to man?

Because of the material from which it's made... i.e. because it's an orange LED (and so you can distinguish it from the green one even if there's a constant stream of packets coming in).

Jack from Adelaide, strange that you posted this now. I also have an NDX, hard wired to the network via a managed switch.

I have had the symptoms you described several times over the last couple of years, streaming CD's no problem, but move to High Res files, constant buffering, most recently on Monday this week. By a process of elimination I also found that by turning the switch off and then switching it back on again always cleared the problem.

I started off powering the whole Naim system & network down before systematically rebooting, which was a real pain, but eventually came to the realisation that it was just the switch that needed rebooting.     It still reoccurs from time to time, not often, but enough for me to remember what I need to do.

Its almost as if the switch goes out of sync for some reason, and I have had it happen on my GS105 as well as on my 'new' (2nd hand!) sooper dooper Cisco switch, so I cant say its one switch or another that suffers with it. Maybe I should try and log in to the switch to see if I can adjust the speed as you mentioned, see if that stops it from happening for good.

As mentioned, NDX is not "gigabit" capable.  And it doesn't need to be.  A 100Mbps ethernet is plenty fast for hi res music, and a modern standard switch can handle this.  Something is amiss with the network hardware; the switch or the cables . . .or something!  

It can also be something else on the network that is causing conflicts, such as an Amazon Echo, or a faulty Apple Time Capsule.

To remove the latter possibility, strip down the network so that all extra devices are removed, and if you're no longer getting dropouts, add them back 1 by 1 until you find the offensive device.

For me at the moment Bart it is an infrequent occurrence, so a simple disconnect / reconnect of the switch does the trick and is fine. I guess if it was a regular occurrence it would be a different story and 1x1 solution you mention would be the way to go, though I don't have any such devices as mentioned.

Seems like Jack from Adelaide is also sorted by the sound of his post.

But its worth noting in case anyone else should have a similar circumstance.

Hi all, 

Yes, I notice that most people who post on forums are asking questions but few are offering solutions. So I thought I would redress the balance! 

As Chrish said, it's simply a matter of powering off the switch while it is connected to the NDX, Computer and the ethernet to the outside world.

Incidentally, here is an interesting observation that I made during my troubleshooting: You would think that one configuration which would HAVE to work would be just your computer connected to the NDX wouldn't you? Actually it doesn't work at all because all the ethernet devices have an address which is assigned by a thing called a DHCP server and when you aren't connected to the ethernet (and your ADSL modem) there is nothing to assign the addresses so everything just sits there in a  state of confusion. I haven't tried it but I would hazard a guess that if you were on a mountain top in the Himalayas without internet connection you could probably assign a so called "static" IP address to your computer and the NDX. I am sure Naim would have thought about this. (I heard the Hi Fi market in the Himalayas was sky high...)

Incidentally Chrish, by an amazing coincidence I pronounce the name Chris exactly the same as your member name after I have had a few glasses of Coonawarra Reds...

 Was the same for me when I visited your lovely city a few years ago and ended up in the Barossa valley...

Never made it to Barossa myself but wine tasting in the  McLaren Vale was a favorite weekend passtime when I was living in Adelaide (back in 1996). As for stuttering I had my own issues (also with NDS and reported on this forum) which were in my case most likely due to my older NAS.

Lucky chap, having lived in Adelaide... Anyway, have your stutters now stopped then since changing your NAS, DrPo?

Yes indeed (been lucky). And yes, stuttering seems to be a distant memory... at least for the time being!
