Solving LAN Problems Continued Problem The NIC loses connection (Loss of Link). The computer will not power on when a wake-up packet is sent. Possible Cause The connection from the LAN cable to the network is loose or disconnected. A wake-up packet was previously received by the computer. If you are connected to a hub or switch, the link LED on the back of the adapter is off. If the link LED does not come on when the computer is turned on, a link is not established with the hub or switch. Solution Disconnect, then reconnect, the LAN cable. Reestablish the network connection. The reception of a wake-up packet will set the adapter to a special state. This condition must be reset before the adapter will accept another wake-up packet and turn on the computer. Check the computer's BIOS for power settings. The link LED on the back of the adapter should be on, even though the computer power is off. Try turning the computer on. If the LED now lights, the adapter is not receiving power in standby mode. Check the cabling or substitute it with a cable that has been verified to work correctly. Make sure the hub or switch is either 10BaseT or 100BaseTX and is turned on and fully functional. Check with your local Compaq authorized service provider for an updated BIOS. 16-20 Troubleshooting
