    [SOLVED] Ethernet 'activity' LED not working


    Two LEDs on an Ethernet port - green and orange (which I'm sure you all know). Lately, I noticed the orange LED is no longer illuminating.

    I had to make some disk images in Linux today, so I booted up from a LiveCD - the LED worked from the Linux system.

    I've tried restarting, reinstalling the driver (both via Windows Update and from the Realtek site) - neither method fixed it.

    The connection still works fine as far as I can tell!

    Thanks for any suggestions.

    Just a quick update:

    I've found that switching the duplex mode to 10Mbps (half or full) uses ONLY the orange LED, but any other setting just uses the green one, including 'Auto negotiate'. So it's not like the LED is bust...

    Sorted. I guess after playing around with the duplex modes and/or drivers, the problem resolved itself after a sleep and wake-up ...of the computer :).

    So for future reference, as I've seen people re-installing drivers to no success, try fiddling with the duplex settings and then do a restart or something.
