Performance issues
The troubleshooting notes in this section are provided to resolve the following types
of performance issues.
•
Inability to transmit data over the HD-PLC network
•
Slow data transmission speeds (interrupted video or audio, slow download
speeds, etc.)
•
Intermittent or varied performance (faster at certain times, slower at others)
•
Interference caused by an adaptor
•
The
PLC
indicator is not lit in blue even though you have registered the
adaptor.
Troubleshooting notes
In most cases, performance issues such as those listed above can be resolved by
performing the following troubleshooting notes. Each note contains several steps.
After you perform each step, test the terminal’s network speed (see page 12) to
see if the issue has been resolved. For more information, access the Panasonic
PLC Support Site at:

Troubleshooting note #1:
Adaptor issues
Perform each step until the performance issue is solved.
1.
Confirm that the AC cords of both the master and terminal adaptor are
connected to the wall outlet. If an adaptor’s
LAN
indicator is not lit, the adaptor
is not receiving power.
2.
Confirm that all LAN cables are securely connected to each adaptor. Use
high-quality LAN cables. Also confirm that other network devices (routers,
hubs, etc.) are turned on as well as properly connected and configured.
3.
Disconnect the AC cord from the master and/or terminal adaptor, then
connect it again to restart the adaptor.
4.
Try connecting the master and/or terminal adaptor to a different wall outlet.
5.
If you are not able to connect an adaptor’s AC cord directly to a wall outlet and
must use a power strip, make sure the power strip is plugged directly into a
wall outlet and not to another power strip.
6.
Make sure the power strip does not have a noise filter or a surge protector, as
these features may interfere with the performance of your adaptors.
7.
Use a power strip with an AC cord that is as short as possible.
8.
Re-register the terminal following the procedure on page 15.
If the performance issue is not solved, continue to the next troubleshooting note.
