change without notice. 

Powerline devices on the same network must use an identical network ID and encryption 
key. The HDX111 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 HDX111 Adapter 
to change the Powerline network ID and encryption key. 

To return the HDX111 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 on your Resource CD. See the User Manual, located on your Resource CD, and 
also available at http://www.NETGEAR.com/support.

To change the default Powerline encryption key to secure your HDX111 Adapters:

1.

Verify that all the HDX111 Adapters on the Powerline network are plugged in.

•

Determine which HDX111 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 HDX111 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.

The AP light blinks for 30 seconds and then remains on. The HDX111 Adapter does 
not discover a security AP, so it becomes the security AP and generates a new 
network ID and encryption key.

3.

Press the Security button of the same HDX111 Adapter again, for 3 seconds, until its 
AP light blinks. This puts it into search mode.

4.

While the AP light is still blinking on the security AP adapter, press the Security 
button of the next HDX111 Adapter, for 3 seconds, until its AP light also blinks.

The second HDX111 Adapter discovers the security AP. The second HDX111 
Adapter’s AP light blinks 3 times and goes off. It is now configured with the same 
network ID and encryption key as the first adapter.

5.

To secure additional HDX111 Adapters, repeat steps 3 and 4.

Note: After you secure your network, the AP light stays on only for the HDX111 Adapter 
that is the security AP for the Powerline network. Adapters retain security settings even if 
unplugged.

The HDX111 Adapter automatically goes into Standby mode to save power when the 
Ethernet link is down for 5 minutes. In Standby mode, the LEDs are off, and the Status 
LED blinks twice every 5 seconds. The HDX111 Adapter has to be up and running for at 
least 15 minutes before it can automatically enter standby mode.

You can press the Standby button on the front panel of the HDX111 Adapter to turn 
Standby mode on or off.

Note: The first HDX111 Adapter that you plug in automatically works as a master. It will 
not automatically enter standby mode if there are other active HDX111 Adapters on the 
same Powerline network.

Safety Warning: Disconnect from power before servicing.

All lights on the HDX111 are off. Make sure that power is supplied to the electrical 
outlet, and that the Powerline device is not plugged into an extension cord, power strip, or 
surge protector.

The Ethernet light is not blinking. There is no data traffic. Make sure that your 
router and modem are switched on, and that the blue Ethernet cable that came in the box is 
connected between the HDX111 port and a router LAN port. Verify whether a computer 
connected directly to the router can access the Internet.

The Status light is blinking red. The devices cannot find each other. Make sure that 
all Powerline devices are plugged into outlets with power and that they use the same 
Powerline network ID (see “Securing Your Powerline Network”). 

After security is set up, the network does not work. Replug all HDX111 
Adapters, and redo the steps in “Securing Your Powerline Network”.

An appliance plugged in near the HDX111 Adapter is affecting network 
performance. Plug the appliance into the pass-through AC outlet of the HDX111 
Adapter if the power consumption of the appliance is 15A or less. The pass-through outlet 
filters out most of the noise that can impact Powerline performance. For more help with 
troubleshooting, see the User Manual located on the Resource CD, and also available at 
http://www.NETGEAR.com/support.
