Chapter 5: Troubleshooting
Please reference the items below if you continue to experience difficulty with installing
and using your TPL-402E 500Mbps Powerline AV Adapter with Bonus Outlet.
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-402E 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-
402E powerline adapter. All LEDs will turn off and turn back on. This will reset the TPL-
402E powerline adapters to the default settings, network name/security key
assignment “HomePlugAV”.
The TPL-402E 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-402E to a power strip or surge protector may degrade network
performance or completely stop network signals.
The TPL-402E should not be used on GFI protected outlets and electrical systems with
AFCI circuit breakers as these items will filter out powerline signals.
The TPL-402E 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-402E may not be able
to establish connectivity between different circuit breaker boxes. In this case, connect
a TPL-402E powerline adapter to a power outlet located on each of the circuit breaker
boxes, and then connect an Ethernet cable between the TPL-402E powerline adapters
to bridge the two circuits together. This will allow the TPL-402E powerline adapters
from different circuit breaker boxes connect to each other.
