NDX signal drops out whilst playing

I'd suspect the home plugs or Router. If you can temporarily bypass the home plugs with a cable (or take the NDX up to where the Router is) then you can check if these are causing the issue. If this link is fine then i'd be tempted to get a separate switch - connect one port to your router, one to the NAS and one to your home plug and this ensure your 'audio' network isn't affected by traffic on the main network. A small 5 port job from Netgear (about £25) will do the job. 

Are your routing the ethernet connections to NAS thru the BT hub - ie. using the BT hub as the switch ????  If so that could be your problem,  I had mine that way & altho' OK for a while it got hot & lost wireless.

My diagnosis was the hub could not handle the traffic, so I added a switch connected directly between NDX & NAS & a branch off the switch to the BT hub.  That completely fixed it, I have since played iRadio (from the BT Hub) all day a number of times & also +5 hours from NAS. The hub runs at normal slightly warm temp & the new switch is stone cold - no drop outs no buffering & everything up to 192kHz when its available.  

I would first take Mike B's advice and add a proper switch. That is inexpensive.

I have no idea what delvio plugs are -- tried Googling them.  If they are ethernet-over-mains technology, then I'd blame that if the switch doesn't fix your problem.  You could try a different brand, or just admit defeat and try to install ethernet cabling. 

I suspect the Ethernet over the mains devices are not helping. (horrible things)  Most can only operate in a  half duplex type mode and the NDX/NDS etc are most happily when running with regular duplex operation (ie data flowing both ways at the same time over the Ethernet). Also Ethernet over main devices are prone to interference and interruption and also cause phenomenal amounts of their own RFI within your house.

Guys, sorry to creep in on this thread...

I have a Sky hub, which I thought acted as a switch, as it has four inputs. My ND5, Qnap NAS and Sony Blu-ray are plugged in. Is it better to get a separate switch, and if so, what make? As there are loads out there, all with different prices. How would the new switch be connected to the Sky hub?

Cheers

Connect directly between NDX & NAS & a branch off the switch to the router & other stuff.

+1   ..and I use personally and install TP-Link gigabit switches when doing network stuff for Naim customers.   Very reasonably priced, very reliable and excellent tech support (if any were needed).   Bought from that rain forest site with next day delivery  (how do they do that?)

Think the switch could be the answer - the NDS is plugged directly into the BT Hub, then via develo plug (through Mains) down stairs to room where system is then second develop plug through Ethernet into NDX - looking a various mapping on web this seems to be pretty easy (famous last words)

If it's a new Homehub, then the switch is a high bandwidth device. If an old Homehub then you may have problems with it. However switches are full duplex devices and that's what your Network player ideally needs, and I would definitely hard wire the NAS/UPnP to Network player link for optimum performance. If you definitely need to use Ethernet over mains use it between a remote switch (with your NAS/UPnP and Network player ) and your broadband router (Homehub).

Thanks Simon

spend the first part of the morning on phone to BT - brand new hub - which runs hot and then freezes - do BT get the irony of this statement - so BT fixed the router - or so I thought then spend a far more produce 35 mins on phone to Phil at Cymbiosis - who had to re set most of what the BT tech support had changed - but NDX is back up and running nicely - switch ordered from Amazon -

nothing is every quiet a simple as it seems, even BT admitted they have a issue with their brand new routers - great customer service guys

Welcome to the BT Appreciation Club folks

See  my post further up this string & also on other post thread

cheapest upgrade for system new switch has brought more detail to music or maybe the NDX is finding its feet now, don't really mind which one it is to be honest 

Great news antony d !!!  & thanks for letting us know,  its nice for everyone to know the outcome of posts,  that way we can all learn what works & what doesn't.    ----     What switch did you get ???

I have come to the conclusion its probably best in all situations to avoid using router hubs as a NAS/HiFi switch & to have a proper ethernet switch as the direct link & the wireless & branched off that to the other services provided by the router.   

Mike - have NAS and ethernet leaded connected in 1,2 and router in 3 - show far it seems to of currently soloved the issue of dropping signal whilst playing

Good choice,  but then I can't say anything else having a GS105 myself 

It doesn't matter which ports you use

I have my NDX & NAS in the metal ground linked ports as my ethernet cables are Cat7 (screened) in those ports it cross connects the screens between both cables

The wireless router with Cat5e (un-screened) cable is in the isolated port 5,  but it doesn't really make any difference,  its just a "me" thing.  

The wireless router & NAS  are both Gigabit so I get 2x LED's on each of the GS port indicators.  The NDX is 100Mbps so this shows 1x LED

great map of networking - have the switch set up in the same way, use Cat 6 Ehternet - I was reading up on BT Hub this morning - instructions (always a good point to start) informs for using fast serves use the GigE 4 port on hub which I have now done - as with you both from NAS and to router both lights flashing and ethernet to NDX just one - will post update
