I think the problem is that you have set you static IP address to be on a network range that doesn't match that of the range assigned to your default router (the DHCP router)
You probably need to set the NIC to be in the range 192.168.102.2 through 192.168.102.254.
A couple questions:
What is the DHCP range set on the router?
What is the actual IP address of the router on the home network.
What is the output of the ifconfig -a command when the NIC is set to DHCP?
What is the output of the netstat -nr command when the NIC is set to DHCP?
We should be able to figure it out once you have that info.
