Core Infinity listening impressions and comparisons

[Nakatomi63]

After I powered up my D250 I thought "what is this?" It sounded awful, but after 10-15 minutes it got better and is now great again. I can't tell if there is a difference with the new board. There may be some more mid-band clarity as others have mentioned but it is not more involving.

USB and Air over Ethernet work. WiFi doesn't work; I have the same configuration as before but the D250 is not visible in the list of attached devices.
I don't know how to get UPNP working. My NAS doesn't recognize the D250 over the network. Is UPNP only available over USB, or should it work over Ethernet/WiFi too? The manual that came with the new software doesn't say anything about that.

These were the instructions Devialet support passed on to me also there has been some small changes to the configurator, so double check just make sure you have it right.
Please follow these steps to trouble shoot WIfi and Eth

Reset of the config

1. Remove the SD Card  ( this step I bypassed, and it corrected the WiFi issue with out resetting it back to factory}
   
   
2. Long press on the tone button of the remote
   
   
3. 6x short press on the tone button to acces the menu "Information"
   
   
4. Long press on the front button of the Amplifier
   
   
5. Reput the SD Card
   
   
6. Unplug / replug the power cord - Wifi or Ethernet will reappear.
   

Thank you very much for your help. In the end I managed to make it work... partially. At first, both ETH and Wifi were active, but then Wifi turned gray. Although it appears as connected in AIR settings, it appears in gray in the selection menu. In the configuration of the router only appears connected by ETH.
I will try again later to see if wifi also works, but of course, I hope that Devialet improves its software to avoid this strange and unstable operation. The remote also works in an erratic and unstable way ...
