Powerline
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.
