Chapter 5: Troubleshooting

Please reference the items below if you continue to experience difficulty with installing and
using your TPL-401E 500Mbps Powerline AV Adapter.
 Try power cycling the unit by unplugging it from the wall power outlet for 15 seconds and
plugging it back in.
 If the PL LED is red indicating good quality only, try plugging the TPL-401E into another
available wall power outlet to check if you can obtain better connection quality.
 Use a pin or paperclip and push and hold the Reset button for 1 second on each TPL-401E
powerline adapter. All LEDs will turn off and turn back on. This will reset the TPL-401E
powerline adapters to the default settings, network name/security key assignment
"HomePlugAV".
 The TPL-401E can provide better connectivity and performance when plugged directly into
the wall power outlet instead of a power strip or surge protector.
 Connecting the TPL-401E to a power strip or surge protector may degrade network
performance or completely stop network signals.
 The TPL-401E should not be used on GFI protected outlets as some outlets will filter out
powerline signals.
 The TPL-401E should not be used in areas with excessive heat.
 Certain florescent or incandescent lights are noise sources on the electrical and can degrade
powerline performance.
 If your building has more than one circuit breaker box, the TPL-401E may not be able to
establish connectivity between different circuit breaker boxes. In this case, connect a TPL-
401E powerline adapter to a power outlet located on each of the circuit breaker boxes, and
then connect an Ethernet cable between the TPL-401E powerline adapters to bridge the two
circuits together. This will allow the TPL-401E powerline adapters from different circuit
breaker boxes connect to each other.
Power Saving: The device will automatically reduce power usage when the connected devices
via Ethernet are powered off, unplugged or inactive for more than 3 minutes.
Erp (EuP) Operation: Standby Mode
 Disconnect the Ethernet cables from the device Ethernet ports, and after 3 minutes, the
device will enter standby mode. The Power (PWR) LED will flash every 15 seconds to
indicate that the device is currently in standby mode.
 To return to active mode, reconnect the Ethernet cables to the device Ethernet ports, and the
device will re-enter active mode.
