Description of Issue
a network based connection to the AV40 was working well after I installed Nucleus+. I tried also with HDMI and that worked well. I can no longer see the Arcam AV40 as a Roon Ready device under the Settings/Audio section of Roon interface. There is no refresh option in the Roon Ready section.
How do I reset/get back the Arcam AV40 in the Roon Ready secion. I can confirm the Arcam AV40 is hardwired and working on the network.
I’ve tried that already. I will try to set the Arcam/Nucleus to 1Gbps Full duplex to see if that helps, then also change both cables… it could be a ethernet speed negotiation issue… hmmm. I will report back once I’ve done that.
the .NET interface is via the Ethernet port or WIFI. But, I have it hard-wired with Cat6 patch cable.
HDMI works fine… but I need to get it working over Ethernet… It works better and auto turns on the ARCAM receiver via CEC (when I had it working previously with Roon core running of my Windows PC over WIFI… it worked flawlessly…) Windows PC-Wifi, Arcam has always been hardwired.
Can you tell me more about your modem/router setup and whether or not these are managed switches? I had an expert look at the totality of things for me and it was concluded that doubleNAT or multiple subnets might be at play.
Ubiquiti switched network with a udm pro in from for wan and internal network to a Starlink router.
Double nat for sure…… but don’t see what that would have to do with the internal network (126.96.36.199/24) network. Most carriers use CGNAT and this is why my Roon Arc has no hope in hell of running outside the local network…… I wish roon had a solution for double nat for Roon arc. Port forwarding doesn’t work….
This worked flawlessly when roon core was running off my windows 10 PC….
So, when I run the Roon Core off my PC… it works like a charm!.. My pc is WIFI connected, and thru the .NET interface (this is the ethernet interface on the Arcam AV40), it works… as it used to before I purchased the Nucleus+.
Therefore, I would think the Ethernet connection on the Arcam AV40 is fine… Do I have a defective Nucleus+???
Tried setting network switch to full duplex and changed cables… still exhibiting the same behaviour. i don’t see any port errors on the network switch. You mentioned/noted many errors on the nucleus ethernet port?.. I also tried changing to 100M Full Duplex, no change, same issue.
It might help to do what we call refreshing RAAT. Let me list the steps below. It should be a pretty quick change to implement and hopefully, it’s what we need. If not, I will have some next steps lined up for you.
Hi Wes, after a bit more digging around, I believe I’ve resolved the issue.
It seems that one of the WIFI Access Points that my computer was connecting to wirelessly was having issues… once I turned it off, and connected to an alternate WIFI Access Point, it’s working as expected now thru the Arcam .NET input (Which is the Ethernet port on the Arcam.).
I suspected this may be the cause, so I hardwired my laptop and Nucleus+ is working flawlessly… which led me to suspect that the closest WIFI AP to my wireless desktop (where i was having the dropout issues) was the culprit.
Arcam AV40 and Nucleus+ are both hardwired ethernet
HP Desktop is wirelessly connect via 5.0 Ghz. and running Roon on the desktop
Wired/Wireless network is Ubiquiti based, with Starlink Gen2 Modem in bypass mode
So… case resolved, and thank you very much for all your assistance here.
Roon Arc will never work in this configuration, as Starlink and MOST ISP’s use CGNAT
(Carrier Grade NAT) which causes a double NAT… and port forwarding does not resolve this issue.
Are you aware of any solution for this setup for Roon ARC?, or should I raise a different ticket for this?
