Diagnostic LEDs a1.02 LNK: Indicates the adapter is connected to a hub or switch and is receiving link pulses. If the LNK light isn't on, check all connections at the adapter and the hub. Make sure the hub is transmitting at the correct speed and the drivers are loaded. Also, make sure you have the correct wiring configuration for the adapter to the hub connection. Some hubs require a crossover cable rather than a straight-through cable. ACT: Indicates read/write activity on the network. It doesn't always mean there is activity on this adapter. If the ACT light isn't on, make sure the hub and network are operating and the drivers are loaded. 100: Indicates 100 Mbps when on, and 10 Mbps when off.Download Driver Pack
