    Hello.

    I have an Alu iMac (20", 2GHz, 10.5.5), which should have a Gigabit Ethernet port.

    But whenever I connect the iMac to my MacBook via Cat5+ cable, either directly or via a Gigabit router, I only get 10 to 11 MByte/s.

    The switch shows that a Gigabit connection is enabled to the MacBook, but only a 100Mbit connection to the iMac.

    Do I have to change some settings on the iMac or what?

    Open Network Utility and check the details for Network Interface (en0) on the Info tab.

    The Link Speed should say 1 Gbit/s.

    Try a different cable? You allegedly need a Cat5e cable for gigabit speeds.

    Try a different port on the switch?

    I tried that, three Gigabit cables (Cat 5e+) and a different port at the switch.

    But I'm currently not home at my iMac, so I can't look into the Network Utility.

    But tomorrow I will report back.
