Then you don't have the problem I mentioned so we're looking for something else.

You still aren't providing much in the way of information. For example, have you a direct ethernet connection between your Innuos and your 220 from the second ethernet port on the Innuos or do you have both the Innuos and the 220 connected to the same network via a switch or router? Does the issue seem to be related to a particular sort of file (DSD, high resolution, etc)? Does the problem occur when you're streaming files from your own library or using a streaming service like Tidal or Qobuz or both? A bit of info about how and when the problem occurs over and above a simple "I've got this problem and can anyone help?" request.

About the best I'm going to be able to do since it's not the Roon Ready issue and in the absence of anything else obvious is to refer you to Roon's support site and their page on Networking Best Practices:  https://kb.roonlabs.com/Networking_Best_Practices  Hopefully something in that will help.

The Innuos and the Dev are connected to a switch and the switch to the router, and that´s it.
I´m just using Tidal streaming, for now and the problem occurs in a very normal (for me) use.
When it happens i noticed, searching the Dev setup, that there´s no ip adress, just after a reset everything comes to normal.
