Once the tool is downloaded, we can proceed with the installation. Once the

installation is completed, the Power Packet Utility program can be started (via Start,

Programs). The program proposes several tabs corresponding to the various avail-

able functionalities as illustrated by Figure 9.4.

To build a secure PLC local area network, it is necessary to start with the config-

uration of the NEK for the various devices to be connected to the network.

In the Security tab, start with the entry of a 4-to-24-character name in the Pri-

vate network name field. This name is equivalent to the password of the NEK com-

mon to all PLC network devices. The default value is HomePlug.

Any PLC device complying with the HomePlug standard bought in stores can be

connected to a PLC network for which the NEK password default value was kept.

Insofar as the signal propagates beyond the electrical meter of the house, anybody

can connect to this private local area network. This is why it is very important for

PLC network security purposes to change this default value. Figure 9.5 shows the

default password.
