3 If the problem continues, contact your ISP.
The Internet connection is slow or intermittent.
1 There might be a lot of traffic on the network. Look at the LEDs, and check Section
1.4 on page 27. If the P-792H v2 is sending or receiving a lot of information, try
closing some programs that use the Internet, especially peer-to-peer applications.
2 Turn the P-792H v2 off and on.
3 If the problem continues, contact the network administrator or vendor, or try one
of the advanced suggestions.
Advanced Suggestions

is enabled, you might consider raising or lowering the priority for some
applications.
38.4 Network Connections
My network cannot be connected. How can I check the Internet connection
status?
1 Check the LEDs on the P-792H v2 for the following situations:
•If the DSL LED is off, there is no DSL connection. Check if your cables are
connected properly to the P-792H v2.
•If the DSL LED is blinking fast, the P-792H v2 is initializing the DSL line. If it
keeps blinking for a long time, please reboot the device.
•If the INTERNET LED lights red, the P-792H 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.
