Roon RAAT and "An audio file is loading slowly"

[Manfred]

I started my Devialet Journey with D170 now D220Pro CI. With D170, AIR, Win7 everything works fine up Win 10 was introduced. With D220 Pro and the CI module, UpNP did not work - stuttering, AIR with JRMC did not work unstable, stuttering and also as I started with ROON, ROON RAAT did not work "Pause" during playback, until I found the following solution for me:

I have a managed Linksys switch, where my Devialet is connected to (see attached architecture overview figure). 


If I configure my switch according to the following table everything works UPnP, AIR and RAAT:

Manfred, would I be correct to surmise that the following four things made your system workable:
1) Managed switch
2) Restrict port for Devialet to 100Mbps
3) Disable auto negotiation for Devialet port
4) Enable flow control for Devialet port

Also, have you had ANY problems with this set-up when using Roon?

Thanks.

1) Managed switch -yes
2) Restrict port for Devialet to 100Mbps - yes
3) Disable auto negotiation for Devialet port -yes
4) Enable flow control for Devialet port -yes

+ that be my environment, I had to diasable autonegotiation also on the Repeater port and enable Flow Control
