What are the IP's of the NIC's, other machines connected to the hub and modem? Sounds to me like one of the other devices on the hub already has the IP you want

You want not only these two nic can be assigned static ip but also connect to internet by this machine. Right?
Not matter which nic you want to use, please make sure your default route and resolv.conf file.
example as below:

#vi /etc/resolv.conf
nameserver 168.95.1.1

#vi /etc/sysconfig/network

GATEWAY= 210.4.102.254

Please refer to below for more detail information

And what about the answers to the rest of my questions?
