Setting up advanced security
NOTE
The devices connected to the Powerline adapters will temporarily 
lose Internet connection during the security setup.
To configure each network adapter with advanced security:
1. 
On the  first adapter, press and  hold the HomePlug  Simple Connect 
button  for at least one second, until the Powerline LED   begins 
flashing slowly. The adapter creates a new network key for the Powerline 
network to use.

On each other adapter, press and hold the HomePlug Simple Connect 
button  for at least one second, until the Powerline LED   begins 
flashing slowly. When the LED stops flashing, the new network key has 
been shared with that adapter. 
NOTE
The devices connected to the adapters will regain Internet access 
within five minutes.
