HDX crashes on LAN / DLAN

Posted by: Checkthisout68 on 13 May 2015

Hi there, I am still working on the HDX issue. My HDX goes into "please wait" mode after a couple of days. Remote PC maintenance by Naim Germany did not reveal any technical problems. 

 

They have asked my to check and use a direct connection between the HDX and the router and so I ran a long cable all through the living room. Same problems occurred after 3 days, frontend crashes and no network access to the HDX.

 

I found out the HDX only runs in 100Mbit mode as opposed to 1Gbit, although all ports on my router are in so called power mode ( no green mode, which makes it use 100Mbit only). The cable between the HDX and the DLAN power line adapter used be to 7m, the other cable I tried between HDX and router used to be around 10m. 

 

However, I have now tried a brand new cable which is only 5m long between HDX and Powerline adapter and it turns out the HDX now runs in 1Gbit mode, says the router.

 

Questions:

 

1. Does cable length cause such problems? Is more than 5m too long?

2. Does the 100Mbit mode cause crashes on the HDX network interface such as I am experiencing?

HDX runs at 100 not gig so your router is confused.

Hi Garyi,

 

thanks, what does that mean, sorry, i am not sure I understand "runs not gig"...?

The network adapter/card in your HDX as well in as all Naim streamers is limited to data rates of 100Mb/sec which is more than adequate for HiRes audio streaming. For example, uncompressed 24bit/192kHz wav files are only 9,216kb/sec i.e. about one tenth of the maximum data rate of the HDX's network card.

 

My Netgear switches have indicators next to each port (two lights for 1Gb/sec speed and one for 100Mb/sec) and the port feeding my NDS shows as 100Mb/sec because, although the switch and the ethernet cable to the NDS are 1Gb/sec rated, the NDS spec. is 100Mb/sec.

The 100 Mb or 1 Gb question is not important. All gigabit Ethernet devices are quite happy having 100 Mb connected to them and will work fine.  Also there is no problem with lengths of Ethernet cable up to a few tens of metres.  If your system is working fine for a couple of days and then shows "Please Wait", this suggests to me that your router is assigning your HDX a different IP address, perhaps because the original DHCP lease has expired. You could check that by looking at your router web server before and after you get this problem and maybe you should also trying allocating a fixed IP address to your HDX.  Hope this helps....

Hi David,

 

Well, the HDX runs with the same IP always. I can check a box for this function from within the Router menu. The router also does not assign any different IP. I have extended the lease now from 10 days to 3650 days.

 

If I use Set IP tool and force two IPs onto the HDX, the router changes the backend IP after reboot even when NOT set to fixed IP, it simply does not accept the HDX proposal.

It is loosing the IOS devices first. Now for 12 hrs min while the MacOs App still works fine. Strange.

There are a number of things that can 'screw up' the home network.  I was having trouble for a few months with the music pausing and then seeing "cannot play" messages.  I re-did my home network, first with the minimal hardware needed for the music, and then added devices one by one.  I eventually saw that my Apple Time Capsule, when on the network, was causing my problems.  I did a factory re-set of it and all has been well for many months now.  I never did figure out just what was going on, but I CAN recommend this approach.  

 

(Perhaps the Time Capsule was somehow flooding the network with packets . . . or its wifi which I relied upon was wonky.  In any event, after a reset it has behaved perfectly and my home upnp music network is bullet-proof.)

 

So for me, it was not ip addresses, etc.  Just a misbehaving device.

Funn, I do run an Apple Time Capsule...will try.

How are you using the HDX? UPnP server, or local playback, and what other devices are on your network? Depending on how you have it set up, I'm wondering if you could reconfigure your LAN to make it depend on your (ISP provided??) router only for internet connection and DHCP server. Let a decent switch or 2 handle the data instead. Also maybe eliminate the potentially problematic powerline connection?

Update:

 

I think the Apple TimeCapsule is at least one of the culprits because playing with its settings today immediately made the HDX crash, so there seems to be some connection. 

 

I have taken the TimeCapsule out of the equation for now and will keep on watching this for 3-5 days which is the typical duration for at least one crash. 

 

ChrisSU: I am using the HDX as UPnP server as well as for local playback in the living room, a switch might be an option. Power line cannot be eliminated, but it did not cause the crashes because it also happened when I had the HDX connected directly with the router.

 

Will get back with more updates.

Chris,

 

You're not the first person I've heard of having problems with Time Capsule, whereas Airport Extreme (the same thing without the hard drive) seems to be OK. 

 

I considered powerline adapters ( and my dealer suggested them) as an option when I bought my Unitiserve, but was put off by the stories I'd heard about RFI and reduced sound quality. I started off connecting it to the streamer via WiFi, and that was, at best, unreliable. Like some other forum members, I moved the US close enough to the streamer to connect both of them to a switch, so that UPnP is over wired ethernet. The connection has been rock solid ever since, and sound quality improved significantly. I have an Airport Express attached to the switch as well, and an Airport Extreme attached to my router, so web streaming and iRadio are still wireless. Maybe this sort of configuration would work for you? 

 

Good luck, hope you get it sorted soon.

I can confirm it must have been the Time Capsule. No crashes since stopping its DHCP server for 5 days now. Special thanks to Bart for the hint.

 

PowerLan does not seem to cause any problems in my setup.

 

Its all fine now, just for the record.
