HDX111 Powerline HD Plus Ethernet Adapter User Manual
Installing and Using the Powerline HD Plus Ethernet Adapter 1-7
v1.1, March 2008
Adding a New Powerline HD Ethernet Adapter
If the Powerline network ID and encryption key are set to the default setting of PowerlineHD, all
you need to do is to plug the new Powerline HD Ethernet adapter into an electrical outlet and
connect its Ethernet cable to a PC. If the default setting has been changed, use the same method to
work with the new device.
• If you used the Security button to customize the network ID and encryption key, see “Securing
Your Powerline Network” on page 1-7.
• If you specified the network ID with the HDX111 configuration utility, see “Specifying Your
Powerline Network ID” on page 2-9.
Powerline Network Security
Powerline devices on the same network must use an identical network ID and encryption key. The
Powerline HD Plus Ethernet Adapter default Powerline network ID and encryption key are both
PowerlineHD. If you do not set up security, anyone nearby with a Powerline network can use
these to gain access to your network. Use the Security button on the Powerline HD Plus Ethernet
Adapter to change the Powerline network ID and encryption key.
To return the Powerline HD Plus Ethernet Adapter to its factory default settings, press the Security
button for 12 seconds until the Status light goes off; or use the NETGEAR HDX111 configuration
utility. See Chapter 2, “HDX111 Configuration Utility.
Securing Your Powerline Network
To change the default Powerline encryption key to secure your Powerline HD Plus Ethernet
Adapters:
1. Verify that all the Powerline HD Plus Ethernet Adapters on the Powerline network are plugged
in.
• Determine which Powerline HD Plus Ethernet Adapter will be the Powerline security
access point (AP). One HDX111 acts as a security AP in your Powerline network.
• For best video performance, select the HDX111 connected to the PC or device where your
video files reside to be the AP.
2. On the Powerline HD Plus Ethernet Adapter that will be the security AP, press the Security
button for 3 seconds until the AP light blinks. This indicates that it is searching to see if there
is already a security AP on the Powerline network.
