If you do not have any lights lit on your D-Link adapter, try the following:
- Make sure drivers are loaded OK in device manager. If there is a yellow exclamation mark, then the drivers are not loaded properly.
- Verify that the adapter is correctly seated all the way down in PCI slot.
- Try a different PCI slot.
- Try a different Ethernet cable. If you pinned the cable yourself, please try a store-bought cable.
- Try a shorter Ethernet cable.
- Disable any other network adapters.
