Vista - Vista Ultimate cannot detect direct cable connection

Hi MS Crew,

I'm using Vista ultimate, and when it comes to internet connecting, I just
need to use a ethernet cable connected from my PC straight into an Eternet
port and than converted to Fibre Optic (complicated but.. www.penangfon.com
how it works)

I've never had an issue with this when it comes to XP, as it detects given
IP automatically, however for VISTA, i'm having issues, i disabled the TCPV6
thing, + even used the command netsh to disable the autotuning incase it
couldn't detect, however same results, i'm unable to connect to the internet
succesfully, Even if i did use a given dns or ip, same results.
