Windows 7: Ethernet 'activity' LED not working

[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.

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.
