NDI application not connected via USB Ethernet adaptor

NDI application not connected via USB Ethernet adaptor

by Sandra Choi - Number of replies: 1
My NDI Linux-based application fails to stream via USB Ethernet adapter, while it works fine over Wi-Fi and a direct Ethernet port.
  • USB Ethernet adapter: UGreen (ASIX Electronics Corp. AX88179 Gigabit Ethernet)

Wireshark shows frequent TCP connection setup and teardown, and alternating port numbers.



This is the result when running `netstat` on the device terminal while streaming NDI, TIMEOUT
