Multiple ethernet/wifi cards prevent device discovery

[ryangriggs]

Hello, my laptop has three ethernet connections: 1 wired, 1 wifi, and 1 wifi direct to a miracast display. If the miracast connection is active, device discovery fails: it reports 0 devices found. However, if I disable the miracast display, which removes the wifi direct connection, discovery works properly and reports the ONVIF devices present on the network.

Is there a way to list the ethernet connections which are present, and then to specify which connection to use for sending the multicast/discovery packets?
