Chapter 38 Troubleshooting • If the INTERNET LED lights red, the P-793H v2 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. 420 P-793H v2 User's Guide
