    Is the router configured correctly? Some ports on some routers are only 100 megabit even if the others are 1000.

    There are a few things that will determine the speed.

    Type of cable, are you using at least a Cat 5e or Cat 6 cable? Have you tried swapping with another cable connected to a device that is connecting at gigabit?

    Settings on the Mac, have you checked to see that its set to automatic?

    What is it connecting to? A gigabit port or something different?

    Have tried the above, with another machine which does connect at 1000 using the same cables and same location in the house and its works fine...

    all router ports are 10/100/1000

    I think i have narrowed this down to an issue with the mac its self. Im not to clued up on mac os fine configuration, and have not been able to find anywhere to force or change the link speed.... Please correct me if im wrong...
