Question : Orange LED on network card. What does it mean?

Network card in one machine.....there is an intermittent problem with network access. I note from the back of the machine that the LED on the NIC is orange...I would expect green.
Strange thing is that if I move the machine to another room and plug in to another point, with a fresh working cable also, the LED IS green. I moved another working machine onto the "problem" socket and got a green light on that one too.
So from that I can deduce......what???

I think the key here is what does that orange LED actually indicate....am I chasing a red herring?

Cheers

Answer : Orange LED on network card. What does it mean?

When a LED goes from green to orange, it means that the network speed has dropped from 100 Mbps to 10 Mbps. The network card has been set to auto speed, and when it has encountered a high level of noise, it will drop to 10 Mbps as it is more reliable. ie. The max transmission distance for 100 Mbps is about 100m, but for 10 Mbps, it about 2 km !!
