pla6456 ethernet

Why does my pla6456 ethernet show ETHB as 100 and not 1000  even though I'm connected to a gigabit router with a 300Mbps internet connection? Using cat5e cables.

    Hi @diplexer

    Please check the router above the PLA if the port speed has been limited to 100M by the router.
    If is is not able to change the port speed with the router, you can try to switch other ethernet cable and check if the ETHB still show 100 port speed.
