Interpreting the

Network Status

Lights

Select Ethernet network interface controllers include network status lights:

The link light illuminates when the system is physically connected to an active network.

The activity light illuminates when the computer detects network activity. When the system is connected to a highly used network, the activity light will remain on almost constantly.

The 100TX light illuminates during 100-Mbs operation.

Some NICs include only two network status lights where link (light on) and activity (light blinking) are indicated by one light and 100-Mbs operation is indicated by the second light.

If Remote Wakeup is enabled, the link and activity lights will remain functional even when power to the computer is turned off.
