    Unhappy TL-SG2008 1000mbit not working, only 100mbit

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    Hi all,

    My installation is PC -> dropcable to wall-socket/connector -> cat7 cable running around house to basement (20m) -> connector -> cat7 patch cable -> Switch TL-SG2008.

    When connecting my pc I only get 100mbit, not 1000mbit.

    If I wire the pc directly in the TL-SG2008 I get 1000mbit.

    Any suggestions to what is wrong, maybe these pictures can help from the internal cable-test?

    Picture 1 shows when cable is directly in switch.
    Picture 2 shows when I use the long wired house installation

    Is the missing PAIR-C and PAIR-D the error because they are required for using 1000mbit? - If so I assume the wires in connectors are not working as they should?



    Thanks for any help!

    Yes. One of the cables or connectors is wired for 100 Mbps only - hopefully not the CAT7 installation, but if installed by an electrician I wouldn't be surprised too much. See https://allpinouts.org/pinouts/conne...ase-t-gigabit/ for the correct wiring of 1000BASE-TX cables.
