Chapter 25 Troubleshooting
P-79X Series User’s Guide

•If the DSL LEDs are off, there is no DSL connection. Check if your cables are connected properly
to the P-79X.
•If the DSL LEDs are blinking fast, the P-79X is initializing the DSL line. If they keeps blinking for
a long time, please reboot the device.
Note: For Internet access setup or point-to-point connections, the DSL1 and DSL2 LEDs
indicate the status of a single connection (act as one LED). For point-to-2point
connections, the DSL1 and DSL2 LEDs indicate the status of connection 1 and
connection 2 respectively.
•If the INTERNET LED lights red, the P-79X attempted to become IP connected but failed. The
reason might be no DHCP response, no PPPoE response, PPPoE authentication failed, or no IP
address from IPCP. 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.
2 Excess errors may occur if the quality of your line is poor. If you hear noise on the 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.
