No IP on Unitiserve

I suggest that the first thing to try is to restart your Unitiserve.  You must shut it down correctly though. Press the front panel logo for a few seconds until it starts to flash and then leave it alone until it stops flashing and the logo is off.  Then turn the rocker switch on the back panel ( top right hand corner when looking at it from the front) off and on again. The logo will start to flash and after about one minute it will stop flashing and stay on. Your Unitiserve should be back on line now.

Hi David,

I did that twice, but no result.

I forgot to mention that I am a Mac user.

Turn off the router, the switch and the Serve. Then turn on the router and let it sit for a few minutes. Then the switch. Then the Serve. 

OK, I tried it, but it didn't work. Still no IP-Adress.

Perhaps your Powerline adaptor thing has conked out. Try connecting the Serve with a wire to the router or switch. Can you avoid the Powerline going forward - they are horrible things. 

I was going to suggest first that you try unplugging and replacing the cable between your Unitiserve and your LAN. You don't need to reboot the US again because it should pick up that it has an Internet connection again.

But if that doesn't work then I would do as HH suggests.

Tomorrow I will try avoiding the Powerline but as I mentioned before, there is a switch connected to that powerline adapter and the Unitiserve is connected to that switch. All other connections with that switch are working. So I think the problem is not the powerline adapter.

Well try the unplugging and plugging I mentioned. This worked once for me when my Unitiserve stopped talking to the switch next to it.

Just try to bypass the power-lan adapter. If you can borrow a long LAN cable from someone and run it between your router and the switch / directly to the UnitiServe.

Come to think of it - why do you need a switch between the LAN socket (from your power-lan) to your UnitiServe?

From one day to the other my Unitiserve had no IP Adress. Router is set to DHCP. I use a Power-LAN with a connected switch. The Unityserve is hooked to this switch. This combination worked well for more than 2 years now.

Since today the Unitiserve has got no IP-Adress. All other hardware connected to the same Power-Lan and switch are working very well.

I'm not very familiar with network problems.

Thank you so far

Harald

Harald, not sure what a 'Power LAN' is, but remember you should really be using Ethernet or a good wifi rather than alternatives and kludges. If Power LAN is a data network over the mains type product, be wary... they are inherently less reliable than Ethernet  and also tend to work in a half duplex mode. It may well be its interfering with the timing of the DHCP exchange or losing frames with the server which can be quite sensitive between host and server. Try using a proper Ethernet patch lead between your router switch and streamer to see if it starts working.

You can manually assign an IP address on your streamer, but I suspect if you are having trouble with DHCP over your PowerLAN, you may well have issues with Apple and UPnP multicast discovery as well making streaming services unreliable. DHCP and multicast discovery require a reliable underlying network with minimum frame data loss, and there may well be new noise / appliance on your mains or even neighbour's mains that has tipped your network over the mains product into being to unreliable for your streamer and server.

Don't overlook that the OP says it all worked fine for two years, so while I agree with your comments about power LAN etc in general, what we are looking for now is a fault not a poor network configuration.

David - indeed please look at what I said however - power line adapters are inherently unreliable - they are sensitive to noise and conditions on the mains - they are  changeable in  performance. You can't assume previous operation is an indication of future operation. A new appliance could have been attached on to the OPs mains or even a close neighbour's mains - especially if also a power line adapter - and it could push the power line adapter outside an acceptable working performance envelope that Naim requires.

The Naim devices are designed for Ethernet or Wifi - best use Ethernet or Wifi.  Phil from Naim support says he sees many reliability or 'network issues' from customers using power line adapters with their home streaming and home networks  - sure they can work for some - but ultimately its a bit of a lottery over time.

As I said an easy test is to use Ethernet, even temporarily between streamer  and router/switch and see if the DHCP starts working - simples.If still not working then at least in this regard you can rule the power line adapters out of the equation - but I still think you will have reliability issues over time on Apple and UPnP discovery

I'm not sure that a specific, diagnosable 'fault' as such is the issue in many cases like this, even when a device that has worked for some time becomes unworkable. As per Simon's last sentence above, if something has tipped the network over the edge, better to seek a more robust network setup.

Well I agree with your last phrase - it is better to look for a more robust network setup.

Got a long enough ethernet cable and connected the US direct to my FritzBox 7490. The Problem remains, no IP.

How can I change from Ethernet to WiFi?

As I know the US-System software is a Windows based sytem. So I guess the network driver of that system is damaged or the network hardware itself is. Is there a way to check it by myself or do I have to send it to the distributor?

thank you all so far for your help

Harald

The Unitiserve doesn't support wifi.

it does sound a bit like a fault with your Unitiserve. One thing you (or your dealer) can do is connect a VGA screen (as used for an older PC) to the VGA socket on the back of the Unitiserve and see what messages, error messages possibly, it gives you as it starts up.

if you can't do this yourself then I suspect it will need to go back to your dealer who may then need to send it back to Salisbury. You could discuss with Naim Technical Support who will probably suggest the VGA screen idea. They can also connect remotely into your network if you have a PC on it (not a MAC) but I'm not sure there is much they would be able to do if your US isn't connecting to your network.

Harald, how are you searching for the Unitiserve IP address? Are you looking at the list of connected devices in the router? If you make a direct Ethernet connection between router and Unitiserve, then restart both devices, and the router still can't see it, that might suggest a fault in the Unitiserve.

Contacted my dealer. Tomorrow I return the US to my dealer for repairing.

I will keep you informed.
