To which Ethernet port of the Ui24R mixer can I connect my Wi-Fi Router?

Answer:

You can connect your Wi-Fi Router only to the ETHERNET port of the mixer.  This port can be used to every type of LAN connection.  The ETHERNET 2 port is used only for the cascade feature allowed with other Ui24R mixers. ​​

For the LAN settings please refer to the 112. page of the mixers User Guide:
