Note: The IP address of the USB Ethernet connection is 192.168.3.1. When configuring the host interface the IP
address assigned to the host must be on the same subnet.

Once the USB cable is plugged in, the Windows 7 or 10 OS should recognize and install the USB Ethernet driver. Ensure
the USB Ethernet interface is used for bridging the Wi-Fi on the WB50 to the host by removing any connected Ethernet
cables and disabling any Wi-Fi interfaces on the host PC. Network interfaces can be disabled through from the Start menu:
Control Panel > Network and Internet > Network Connections.
