Mac OS X will occasionally show Bluetooth PAN in the Network PreferencePane even though the connection is actually wireless.
The Monitoring Client will then report the internal IP address as:
Report Internal IP Address
Primary IP: 10.11.100.115 via DHCP on Bluetooth PAN
There is nothing that needs to be corrected if this happens. Restarting the computer will frequently set the display back to the expected interface name of "Wi-Fi"
