(3) If light, then check the "LINK (sync)" LED status is normal (illuminated steady is blinking), if not normal, check the adslmodem of the various connectors are normal (from the signal divider to connect to the Adslmodem of the line is connected to the line port, and network card to connect the network cable is connected to the LAN port, whether plugged in, if the connection is not correct, reconnect the cable.

(4) If normal, then check the "LAN" or "PC" LED status is normal. If not normal, check whether the LAN port on the Adslmodem, if connected, then test the network cable is normal, if not normal, replace the network cable; If normal, the computer and Adslmodem shut down after 30 seconds, restart the Adslmodem and computer power.
