I typically set my IP properties to 192.168.110.11 with a subnet of 255.255.255.0. No gateway or DNS is required. Also, the browser must be configured to never dial a connection. If all else fails, you can connect a serial cable to the CallPilot using Hyperterminal at 9600/8/N/1 and VT 100, restart the CP and verify the IP address of the CP.
