Chapter 3: Configuration

3.1 Overview

The PL-751 uses 128-bit AES encryption to block outside access. The key is set by using the Configuration Utility on the CD. By default, the protection is enabled, however, it is recommended to change the default network password. All your Powerline devices must use the same network password in order to be connected together.

3.2 Main Screen

■ Part 1: Scan a Local Powerline device

Double click the PowerPacket Utility icon on your desktop and utility screen will show up as below:

The Main tab shows the Powerline units that are connected to the current computer and other Powerline devices on the home network, and it will also display Mac Address of each device.

Note

If you do not see ANY unit in the device status but the Powerline device does exist, try to unplug all devices and plug them back.

Meanwhile, please make sure the cable is the right type and working correctly. If all seems to be correct, and you still receive nothing in the Device window, try rebooting your computer.

■ Part 2: Detect the Network Powerline device

The Main tab shows all the other Powerline units on your home network. It will represent them by MAC Address, and will also show the available bandwidth to each unit (Units farther away from another Powerline device might have a lower Data Rate). If you add or remove units from your home network, click the "Scan" button to re-scan the network, and refresh with any changes.

Note	Only units with the same Network Password will be shown, (Password case sensitive).
Note	If a unit shows MAC Address of all 0's, this unit might not have a solid connection, or might not connect at all.
Note	If there are units in the home network, but nothing displays in this Network scan, try to unplug all devices, and plug them back (Only do this with the units that you do not view in the network screen, you don't have to do this with all units.)

If the problem persists, try to move the unit closer to this current unit (adjacent plugs on the same wall socket is most preferable). If the problem still persists and that unit is still not shown on the network, then the unit might be defective, please contact technical support. Otherwise if you view the unit working, distance might be the only issue.

3.3 Privacy

■ Setting Up Security on a Local Powerline device

The Privacy tab will allow you to change the Network Password to the unit that is currently connected to this computer. This network password encrypts all data that is sent from this unit using 128-bit data encryption standard (AES).

Note

Every unit on your home network MUST have the same Network Password for connectivity to be established throughout your home. The default network password is "HomePlugAV"

■ Setting Up Security on a Network Powerline 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 Powerline device. To use this you will need to input the DEK for each unit.
