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. 

 

 

 

 

 

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, 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.

 

 

 

Overlapping Powerline Networks 

It is possible to create multiple Powerline networks on the same electrical system 
separated and grouped by different network encryption keys. The Powerline networks 
will work and communicate independently of each other which can provide security 
between different groups of Powerline adapters. For example, if you have five 
powerline adapters (Adapter A, Adapter B, Adapter C, Adapter D, Adapter E), you can 
group Adapters A, B, and C together on one powerline network and group Adapters D 
and E on a different Powerline network. Each group will use a different encryption key. 

 

Note: It is recommended that only a maximum of up to 4 Powerline networks can be 
created per electrical system. Any additional Powerline networks above the 
recommended may result in significant degradation in Powerline performance.
