Chapter 25 Troubleshooting
Check the LEDs on the ZyXEL Device for the following situations:
1
• If the DSL LED is off, there is no DSL connection. Check if your cables are
connected properly to the ZyXEL Device.
• If the DSL LED is blinking green, the ZyXEL Device is initializing the DSL line. If
it keeps blinking for a long time, please reboot the device.
• If the DSL LED lights green and the Internet LED lights red, the ZyXEL Device
has failed to get an IP address from your broadband service supplier. Please
contact your vendor or customer support.
• If the DSL LED lights green but the Internet LED is off, the ZyXEL Device does
not have an IP connection. Please check if you have entered the correct ISP
account and password when setting up the Internet connection. If the status is
the same, reboot the device. If the problem remains, please contact your
vendor or customer support.
Excess errors may occur if the quality of your line is poor. If you hear noise on the
2
line while making a telephone call, you should ask your local telecommunications
office to check the lines in your house or apartment building and the line from
your residence to your DSL service provider.
