Issue Details

I have connected a CompactRIO controller to my PC via USB and its Ethernet IP address is not the default 172.22.11.2 but is 172.22.11.10, although there is only one CompactRIO connected.

Solution

Make sure "Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NationalInstrumentsUSBLAN\DHCPBase" registry key value is set to ac160b00 and reinstall CompactRIO drivers.
