Troubleshooting
Please reference the items below if you continue to experience difficulty with installing
and using your Powerline adapters.
• Do not plug the Powerline adapters into a power strip. Make sure to plug the
adapters directly into a power outlet and not through power strip. Using
adapters through a power strip may negatively affect Powerline connectivity
and performance.
• Make sure to use the built-in power outlet for powered devices to filter out
noise sources that may affect Powerline connectivity and performance.
• Do not use the Sync button for more than 2 Powerline adapters to connect
simultaneously. Wait for each Powerline adapter to connect to your Powerline
network one at a time before connecting the next adapter. Using more than
one adapter to Sync simultaneously may cause some of your adapters not to
Sync and establish connection to your Powerline network.
• Power-cycle the Powerline adapters by disconnecting them from their power
outlets for 15 seconds and then reconnect them.
• If the Powerline (PL) LED is red, try plugging the Powerline adapter into another
available power outlet. The quality of the connection may be better in a
different power outlet.
• If you are having issues connecting the Powerline adapters after changing the
encryption key using the Sync button or Powerline utility, reset the Powerline
adapters to defaults using the physical Reset button.
• Using a pin or paperclip; press and hold the Reset button for 1 second on each
Powerline adapter. All LEDs will turn off then turn back on. This will reset the
Powerline adapters to their default settings. The default encryption key is
HomePlugAV.
• The Powerline adapters can provide better connectivity and performance when
plugged directly into a power outlet. Connecting the Powerline adapters to a
power strip or surge protector may degrade or block Powerline signals.
• Avoid using the Powerline adapters on GFI protected outlets and electrical
systems with AFCI circuit breakers. They may degrade or block Powerline
signals.
• The Powerline adapters should not be used in areas with excessive heat.
• Florescent and incandescent lighting can generate significant Powerline
interference.
• If your building has more than one circuit breaker box, the Powerline adapter
may not be able to establish connectivity between them. In this case, connect a
Powerline adapter into a power outlet located on each of the circuit breaker
boxes. Then connect an Ethernet cable between the Powerline adapters to
bridge the two circuits together.
