primary computer to control the Network
Password of all units on the powerline
network. First Find the DEK (Device
Encryption Key) Key located on the bottom
of each device. Enter this Key into the
Device Password area. Click Add. This
Device Key will then appear in the Remote
Passwords Box. Add all the DEK Keys for
each unit in your house. You can then
change the password remotely from one
computer. This will allow you to change the
password from one computer, instead of
changing the password individually.
Note: The DEK is unique for EACH HomePlug
device. To use this you will need to input the
DEK for each unit.
