Setting Up Security on a Network HomePlug device
The Privacy Tab will allow users to use one primary computer to control
the Network Password of all units on the home network.
You will have to go back to the Main Tab first then 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 bottom window . Add all the DEK Keys for each unit in your
house. You can now go back to the Main Tab 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.
