Connecting 220 to my network

[chrisc]

Have a 220Pro CI
The configuration is set to allow Wi-Fi with a fixed IP address (192.168.1.102) and ethernet with fixed address 192.168.1.104.

Using the remote's source button to scroll through the inputs, Ethernet is not shown (1)

USB and Digital work fine

If AIR is chosen, the display shows the wi-fi symbol and scrolling through the config using the right button shows 192.168.1.102

The router shows Expert220 on IP address 192.168.1.102 on the list of connected devices with the Devialet's MAC address

Using JRiver on a Windows 10 machine, with the Default sound device as Devialet AIR and JR also set to use AIR, on playback there is no sound (2)

Have rebooted PC and Devialet many times

Are there any pointers to what might be the problem with issues (1) and (2)

I am fairly good with computers and networking

Thank you
