HARDWARE INFORMATION

1.  What is the PLW400?

The PLW400 is a Powerline 1-Port Fast Ethernet Network Adapter and Access point in one device.  This adapter provides easy setup and lets you connect wireless networking devices to your powerline network.

2.  What is the warranty period of the PLW400?

The warranty period is dependent on the country of purchase.  For more information about your device's warranty, click here.

3.  What are the minimum requirements to support PLW400?

  • A computer or other device with Ethernet adapter
  • Available AC power jack on the same circuit
  • Other Powerline AV enabled Device

4.  How can I tell if the two (2) AC Power Jacks are on the same circuit?

NOTE:  Make sure first that the PLW400 is configured on the same power jack as the rest of the Powerline equipments.

After configuring the PLW400 on one power jack, move it to another power jack you would like to use.  If the Powerline LED lights up, then it is on the same circuit and should work fine.  If the LED does not light, try other nearby power jacks.

SECURITY SUPPORTED

1.  How do I configure each network adapter with advanced security?

Step 1:
On the first adapter, press and hold the HomePlug Simple Connect button for at least one (1) second until the Powerline LED begins flashing slowly.  This means that the adapter creates a new network key for the Powerline network.

Step 2:
On each of the other adapters, press and hold the HomePlug Simple Connect button for at least one (1) second, until the Powerline LED begins flashing slowly.  When the LED stops flashing, it is an indication that the new network key has been shared with that adapter.

LEDs

1.  What LEDs does the PLW400 Powerline adapter have?

The PLW400 has Powerline, Ethernet, Wireless, Wi-Fi Protected Setup™ (WPS) and Power LEDs.

2.  What colors are the LEDs and what do they mean?

  • Powerline LED - turns ON when the adapter is connected to the Powerline network.  The LED flashes to indicate network activity.
  • Ethernet LED - turns on when a wired network device is turned on and connected to the adapter’s Ethernet (network) port.  The LED flashes to indicate network activity.
  • Wireless LED - turns on when a wireless network device is connected to your PLW400.
  • Wi-Fi Protected Setup™ LED - flashes while a wireless network device is connecting with your PLW400 using Wi-Fi Protected Setup™.
  • Power LED - turns on when the adapter is connected to a powered electrical outlet.

PORTS AND BUTTONS

1.  What ports and buttons does the PLW400 Powerline adapter have?

  • Ethernet port - This Ethernet port connects a computer or another networking device to the PLW400.
  • Reset button – Restores your powerline adapter to factory defaults.  To do this, press and hold the Reset button for at least 10 seconds using a pin or a pointed object.
  • HomePlug Simple Connect button - Configures advanced security (the network password) for your powerline network.
  • Wi-fi Protected Setup™ button - connect with other wireless network devices that have a Wi-Fi Protected Setup™ button.

TROUBLESHOOTING

1.  How do I connect my PLW400?

IMPORTANT:  Before proceeding, make sure that the power switch on the right side is set to I (ON).  If your home network already has security set up (recommended): 

Step 1:
Connect the PLW400 to a power outlet near your main wireless router.

Step 2:
On the PLW400, press and hold the Wi-Fi Protected Setup™ button at least one (1) second, until the WPS LED flashes.

Step 3:
On your wireless router, press the Wi-Fi Protected Setup™ button for two (2) minutes.  The PLW400 retrieves the security settings from the router and connects to your wireless network.

Step 4:
Move your PLW400 to a power outlet near the wireless network device(s) you want to connect.  Typically, this area is not covered well by your home’s wireless network router.  The Powerline LED flashes, and then stays solid when the connection to the rest of the Powerline network is finished.  Your home’s wireless network is now available in the area surrounding the PLW400.

Step 5:
Connect the wireless network device to the wireless network in the usual manner.  For instructions, see your wireless network device’s user documentation.  The PLW400’s Wireless LED flashes, and then stays solid when a wireless network device successfully connects. 

2.  What should I do if none of the LEDs turned on after I installed the Powerline adapter?

Step 1:
Disconnect the adapter from the power outlet. 

Step 2:
Disconnect the Ethernet cable from the adapter.

Step 3:
Wait five (5) seconds.

Step 4:
Re-connect the Ethernet cable to the adapter.

Step 5:
Re-connect the adapter to the power outlet.

NOTE:  If this solution does not work, make sure that the electrical outlet is working properly.  Plug a different device into the power outlet, and try to switch it on.

3.  What should I do if the Ethernet LED does not turn ON after I connected a wired device to the powerline adapter?

When the Ethernet port detects a local network connection, the Ethernet LED should turn ON.  If it does not, do the following:

  • Make sure that the Ethernet cable is securely connected to the adapter.
  • Make sure that the Ethernet cable is securely connected to the computer or other network device.
  • Make sure that the Ethernet adapter on your computer is working properly.

4.  What should I do if I cannot connect to other computers on my local network or to the Internet?

If you did not set up advanced security for the Powerline network, follow these instructions:

Step 1:
Locate the Powerline adapter connected to the computer that cannot connect.

Step 2:
On the right side of the adapter, use a pointed object to press and hold the Standby/Reset button for at least ten seconds.  This resets the adapter to its factory default settings.

If you have set up advanced security for the Powerline network, check the following:

1.  Make sure all adapters on the Powerline network have been configured with the same network password.  The network password must be identical in order for them to communicate with each other.

2.  If you are adding a new adapter to a pre-existing Powerline network with a unique network password.

5.  What does it mean if the LEDs are flashing on my PLW400?

Refer to the following LED behavior to help diagnose the problem:
