Then plug your PLA450 into a power outlet.

The PLA450 is ready for connection on a powerline network.

Connect another HomePlug AV compatible adapter to a computer and then plug it in on

the same home or office wiring.

After configuring the settings on all adapters (see

Section 8.3 on page 88

) your computer can

now connect to the powerline network and to the Internet. Your powerline network can be

further expanded by plugging additional powerline adapters into other outlets in your home

and connecting other computers or network devices (for example, a printer) to them.

In this User’s Guide the electrical wiring network may be referred to as the “powerline

network”.

Your PLA450 is only compatible with ZyXEL HomePlug AV products with the

latest firmware. You can upgrade your other ZyXEL HomePlug AV products by

downloading the latest firmware from the ZyXEL website (www.zyxel.com).

8.2

Privacy and Powerline Adapters

When the PLA450 communicates with each other HomePlug AV compliant powerline

adapters, they use encryption to scramble the information that is sent in the powerline

network. Encryption is like a secret code. If you do not know the secret code, you cannot

understand the message. The HomePlug AV standard uses 128-bit AES (Advanced

Encryption Standard) to safely transmit data between powerline adapters.

For the PLA450 and powerline adapters to communicate with each other they all need to use

the same Network Membership Key (NMK). Otherwise, they cannot unscramble the

encrypted data sent in the powerline network.

The NMK is derived from the network name (password) you assign to the

PLA450 and

powerline adapters. By default all HomePlug powerline adapters are configured with the

network password

HomePlugAV

. This allows all HomePlug powerline adapters and the

PLA450 to communicate with each other without any software configuration. This also means

that if you don’t change the network password, any HomePlug AV powerline adapter

connected to your powerline circuit can see your network data.

Change the network password on your powerline adapters to ensure secure

data transmission on your powerline network.
