Securing your Powerline Network

Powerline networks consist of two or more Powerline devices connected together using

the same encryption key. TRENDnet Powerline adapters automatically connect to each

other over a secure encrypted signal and share the same encryption key (Default

encryption key: HomePlugAV).

In order for your Powerline devices to connect to the same Powerline network, the

same encryption key must be assigned to all Powerline devices in that network.

Powerline devices that are not assigned the same encryption key will not be able to

connect to the Powerline network.

For additional security, TRENDnet recommends changing adapter default encryption key

to prevent a neighbor with a Powerline adapter and the same default encryption key

from gaining access to your network.

Note: After the default encryption key has been changed and the Powerline adapters

have been connected using a new encryption key, the Powerline adapters will retain

their security settings when they are unplugged and moved to a new location. No

additional reconfiguration of the Powerline adapters is needed after the default

encryption has been changed.

There are two methods to change the default encryption key:

• Use the physical Sync button on your Powerline adapter to generate a random

encryption key. See “Using the Sync Button” on page 7

****Recommended method****

• Create a customized encryption key for your Powerline network using the

included Powerline Utility. See “Using the Utility” on page 11

*****If users first use the Sync button method, the adapters will need to be

reset to factory defaults in order to change setting using the Powerline

Utility****

Using the Sync button

Change your default encryption key using the Sync button

The physical Sync button on the Powerline adapter provides an easy method of

changing the default encryption key. The Sync button generates a random encryption

key for your Powerline network. To create a customized encryption key, see “Using the

Utility” on page 11

Note: The default encryption key assigned to TRENDnet Powerline adapters is

HomePlugAV. Before changing the default encryption, please ensure that your

Powerline adapters are already installed and connected using the default encryption key.

See “Installing your Powerline Adapters” on page 5

Important Note: When using the Sync Button to change the default encryption key, it is

highly recommended to plug the adapters into nearby outlets first and follow the Sync

button procedure before installing the adapters in the desired locations.
