Are you sure that the 2nd one (Realtek RTL8139) is definitely set up for Auto DHCP, Auto DNS, nothing hard coded? And just to be sure, the first one too? No sign of the rogue 192.168.1.9 anywhere?
For Realtek - under General Properties - TCP/IP, it states "Obtain an IP Address automatically"
"Use the following DNS server addresses :
Preferred: 192.168.1.9
Alternate: 64.245.166.16
Under Alternate Config, it states "Automatic Private IP address"
For 1394
Under General Properties: Obtain an IP address automatically
Obtain DNS server address automatically
Under Alternate Configuration: "Automatic Private IP Address"
Does that help or did I not answer your question? If you needed something else, please explain.
