I hope you are all keeping well and safe in these difficult times? I wonder if you can help me please?
I am based in the UK and bought a Nucleus+ (Rev A) a few years back. I have a lifetime Roon membership. My music is on an internal 4T SSD. I have about 20k tracks, virtually all ripped from my CDs via iTunes and converted to wav files before importing to Roon. I use an iPad as the Roon client. I used to have the Nucleus+ connected via ethernet to a old Edimax wifi bridge (BR-6428nS V4). Also connected to the bridge via ethernet was my Devialet Expert Pro. My internet router is not in the same room as my hifi hence the use of the wifi bridge. I only turn on the Nucleus+ when I want to play music and turn it off (short press of power button) when I’ve finished listening. Everything was working fine for ages.
I recently replaced the edimax wifi bridge with a Netgear R7000 router operating in wifi bridge mode. I also added an English Electric 8Switch ethernet hub/switch connected to the R7000 and now have the Nucleus+ and Devialet connected to the 8Switch. I also upgraded Roon to version 1.8.
Friday 12th March
I can access the Nucleus+ from my iPad and stream my local music fine no problems. However although I can browse Qobuz content and select an album (I see the track listings) if I attempt to play it the play bar just shows the sweep of a moving blue slider and nothing plays. I can access Qobuz and play albums via the Qobuz app on my iPhone and iPad over the home wifi. Power cycling the Nucleus+ and the R7000 resulted in the situation worsening with no Qobuz content being shown (except playlists - which were empty).
Logging in and out of Qobuz via the Nucleus+ made no difference. More power cycling made no difference. Reinstalling the OS from the web admin gui (version 1.0 build 227) appeared to fix the problem and I could access and stream music via Qobuz.
Saturday 13th March
The following day I powered up the Nucleus+ and was back to square one: Qobuz content visible but not playing. I tried restarting the Roon Server (version 1.8 build 764). This took me back to no Qobuz content at all. Reinstalling the OS again fixes things.
Sunday 14th March
Powered up the R7000 wifi bridge, waited until it was fully active and then turned the Nucleus+ on. Same problem: can see Qobuz content but cannot play any. Changed the Nucleus+ to have a static IP address and set the DNS to 188.8.131.52 (I’d seen a few posts on the community site that suggested changing to the Google DNS can sometimes help). It didn’t help. Tried reinstalling the OS again but this time it did not fix the problem. So I can only view Qobuz content but not play it. I can stream my own content from the SSD.
Monday 15th March
Power up R7000 then Nucleus+. Open iPad Roon app and once it connects there is a button at the bottom of the screen asking me to “Select an audio zone”. Never seen that before? After a minute the button goes away and the Devialet is found. Can see Qobuz content but cannot play.
Remove the 8Switch from the network and connected the Nucleus+ and Devialet directly to the R7000 via ethernet. Restart R7000 and Nucleus+. No change, still can’t stream Qobuz albums. Removed the R7000 and replaced it with the old edimax bridge. This appears to have fixed the problem. I have no idea why? The edimax bridge only supports 10/100Mbit ethernet ports and 2.4Ghz wifi. The R7000 supports 10/100/1000Mbit ethernet ports and was using 5Ghz wifi - could this part of the problem?
Attached the 8Switch to the edimax bridge and connected the Nucleus+ and Devialet to the 8Switch. Everything still works fine but there is a tiny delay in the Qobuz album starting to stream.

Reconfigured the R7000 to use the 2.4Ghz wifi rather the 5Ghz band and tested the setup again. Can’t stream Qobuz albums. Moved the connection back to the Edimax bridge and everything works fine.
I realise you would rethink that this is clearly a problem with R7000 (which it may be) as removing it and replacing with Edimax fixes the problem. However the R7000 is clearly passing network traffic as I can control the Core from my iPad app. If I asked Netgear for help with this surely they would suggest I have an Roon/Qobuz app problem as, in some instances, reinstalling the Core fixed the problem (albeit temporarily).
I wanted to replace the Edimax as it is very old and have now spent £100 on a Netgear that R7000 may not be doing the job. How can I be certain that buying a different wifi bridge will work?
Is there any help you can give me with this problem please? Specifically, when I click to play a Qobuz album what is the connection process in terms of DNS look-ups, new tcp/udp sockets being opened, authentication etc. In short why is this only working sporadically through the R7000? Could the robustness of the connection process need improvement?
I don’t think any of the wifi bridges or the 8Switch have span ports so I don’t see how I can capture a network trace to investigate further.
Any help you can provide would be most appreciated.
