1、 Check the indicator of power supply is on, if not, Make sure the connection of power supply is correct;
Make sure the output of power supply is correct; Make sure the switch of power supply is turned on；
2、 Check the indicator of PC is on, if not, Make sure the connection of cable and network adapter; Make
sure that the correct cable is used;
3、 Check the LINK LED to see if it is twinkling. If no fast twinkling is observed within 3 minutes, please
check whether phone line has been correctly placed; whether ADSL separator is correctly used. If
multiple extensions have been installed, make sure that the separator is installed prior to the junction
box of phone line. If the above items are confirmed and still no fast twinkling of WAN LED is
observed, call the ISP to query whether ADSL service has been provided on your line;
4、 Check the LINK LED to see whether it is unable to change status from fast twinkling to always light,
or whether it changes status to fast twinkling after sometime of always light. If these phenomena occur
constantly, please contact your ISP with a demand to check lines and signal quality;
If there is no problem in the above items, the line and the device shall be working. Problems may come
from your computer configuration or device configuration.
