Best not use static IP, the DHCP protocol in the router is designed to do that.
Finding rooms problems are not normally related to IP address allocation.
I would look at the wireless set up, I suspect its that to the control point (what is it - Android, iOS, phone or tablet)
Try a system re-boot, router started first & let it finish)
If the app cannot find the streamer, it’s possible that the router / WAP is interfering with the communications protocol(s). With a previous router I found this to be the case. The answer for me was to use separate WAP (a Linksys Archer C2 in WAP only mode) only and remove the ISP provided router from the connection path from the App to the streamer and DLNA media server.
It might just be me, I am am always suspicious of any of these extenders, other than a MESH setup. So I would in your case just try switching off all the access points and extenders such that you are just using the router and modem. Then power cycle the router, and then the iPhone and retest.
If that works, then power on the other bits with testing at each stage plus consider a MESH instead if problems repeat.
My thoughts too GadgetMan. A mate has Virgin with a few odd extender things & although not a serious audio user, he’s always moaning about problems, mostly kids gaming & video streaming if I’ve got it right.
I’m a BT user & am in praise of the Smarthub-2 & its designed to match/handshake Halo Disc extenders. Its pretty well feature & user fiddle free, but guess what, it just works.
What configuration changes? It’s a router that dishes out dhcp plugged into a modem.
The wireless access points could cause an issue I guess, they have the same SSID to make changing between then easier but again it’s a setup that hasn’t been a problem with a bluesound node so I struggle to see why the network setup is an issue.
Glad to hear it’s now working for you. I suspect the problem will return when you start moving around the house. You are effectively trying to create a mesh but without the proper handshaking between those devices. A bit like playing in a 5-a-side with a team that are all called Dave, and you ask Dave to pass to Dave
You could try just leaving the phone near the ND5, but I realise that may not be workable.
Other option is to get a pre-loved tablet and keep that by the ND5. In fact the app feels much better on a tablet.
Other option is to have separate SSID’s, but I don’t know how that would work in practice.
I agree, repeaters with same SSID tend to be a pain. It also depends on the wifi driver in the client device, some tend to pick a repeater and stick to it, others switch between the different repeaters all the time which is a recipe for trouble. (The wifi settings may have a config option to identify a specific repeater to use, by its BSSID. It’s certainly the case on my Linux, but it’s a band aid)
In general, repeaters should be avoided and a proper mesh be used
Separate SSIDs usually work fine but are a pain when moving around in the house
