Going through your steps here
When I click change adapter the Local Area Connection says Unidentified network. Double clicking just gives me the status page so I go to properties. When trying to modify the TCP/IPv4 Properties I fill out the IP address but then I can no longer Obtain DNS server address automatically, it forces me to fill this out. Even when I put my DNS info in there I have no progress
Fill the IP address to 192.168.1.X where X is anything but 0, 99, or 255 . Leave DNS and Gateway entries blank and click ok.
Connect the S1 to your computer ethernet port then click start and in the "run" box, type CMD. When the command prompt opens up, type: ping 192.168.1.99
If it the result includes: Reply from 192.168.1.99 then you're good to go and can login to the S1 through a web browser at that IP.
