How Powerline Networking Works

Electrical wiring runs through your home or office, carrying power to electrical outlets in every room. The typical wired Ethernet network uses Ethernet network cables to connect your wired network devices. A Powerline network uses your existing household wiring as the wiring for your Powerline network. To create your Powerline network, use two or more Powerline adapters. Each device on your Powerline network requires a connection (either wired or wireless) to a Powerline adapter.

The PLE400 has one Ethernet port. One of these devices is typically used in a Powerline network to connect your network’s wireless router to the household wiring.
The PLW400 contains one Ethernet port and an access point. You can connect one wired device and several wireless devices to it.

When adding a Powerline network to an existing network, the connections between the Internet, modem, and router stay the same.
Example installation
This diagram shows a basic Powerline network in a house. The router upstairs is connected to the PLE400, which is plugged into an electrical outlet. Downstairs, a gaming console and a computer are connected to the PLW400, which is plugged into an electrical outlet.
Using the household wiring of the home, the router expands the local network to include the gaming console and desktop computer in the living room. Internet access, files, and printers can be shared between the computers and other networked devices. For online gaming, you can play downstairs in the comfort of your living room, while using the high-speed Internet connection of the router and modem upstairs.

Installing the Adapters

Installation overview

To set up your Powerline network, you should

Make sure you already have Internet access and a working home network.
Share Internet access with your Powerline network.
Install Powerline adapters near the network devices that you want to connect to your home network.
Make sure that the wireless devices that you want to connect to the PLW400 have a working wireless feature. An easy way to test this is to first try to connect the wireless network device to your home’s wireless router while near the router.

Tips

If possible, connect Powerline adapters directly to a wall power outlet, and not to an extension cord, power strip, or surge protector.
If a Powerline adapter must be installed onto a power strip, make sure that no other electronic devices are connected to the same power strip.
If possible, position the PLW400 near the wireless devices that you want to connect.
Avoid obstructions (such as metal file cabinets, mirrors, and thick walls) between the PLW400 and any wireless device you want to connect.

How to share Internet access

To share Internet access over the Powerline network, connect your router to the Powerline network (typically with a single-port Powerline adapter such as the PLE400).
To connect your wireless router to your Powerline network

Connect your PLE400 (or another single-port Powerline adapter) to a power outlet near your wireless router. The adapter’s power LED turns on.
Use the included Ethernet network cable to the port on the adapter and to an available port on the back of the wireless router. The adapter’s Ethernet LED turns on. You are now ready to extend your Powerline network to the rest of your home.

NOTE: For advanced security setup, see “Setting up advanced security” on page 8.

How to connect your PLE400

You can use your PLE400 to provide Internet access to the rest of your Powerline network (see “How to share Internet access” above). Or, if you used a different Powerline adapter to share Internet access, you can install your PLE400 elsewhere in your home.
TIP: You can also set up and configure all of your Linksys Powerline devices using the configuration utility. For more information, see “Using the Utility” on page 8.
To add a PLE400 to your Powerline network

Connect the adapter to a power outlet near the network device you want to connect. The adapter’s power LED turns on. The Powerline LED flashes, and continues flashing until it connects to a second Powerline adapter.
Connect the network device’s network cable to an available port on the Powerline adapter. The adapter’s Ethernet LED flashes, then stays on when the connection is finished.

How to connect your PLW400

After your existing network’s router is connected to a Powerline adapter, you can install your PLW400 elsewhere in your home.
TIP: You can also set up and configure all of your Linksys Powerline devices using the configuration utility. For more information, see “Using the Utility” on page 8.
To connect your PLW400

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)
1. Connect the PLW400 to a power outlet near your main wireless router.
2. On the PLW400, press and hold the Wi-Fi Protected Setup button for at least one second, until the the Wi-Fi Protected Setup LED flashes.
3. Within two minutes, press the Wi-Fi Protected Setup button on your wireless router. The PLW400 retrieves the security settings from the router and connects to your wireless network.
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 on 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.
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 on when a wireless network device successfully connects.

Setting up advanced security

NOTE: The devices connected to the Powerline adapters will temporarily lose Internet connection during the security setup.
To configure your network adapter with advanced security

On one of the existing Powerline adapters that already has advanced security set up, press and hold the HomePlug Simple Connect button for at least one second, until the Powerline LED begins flashing slowly.
On your PLW400, press and hold the HomePlug Simple Connect button for at least one second, until the Powerline LED begins flashing slowly. When the LED stops flashing, the network key has been shared with the PLW400.

NOTE: The devices connected to the adapters will regain Internet access within five minutes.

Using the Utility

If you’re having difficulty connecting the adapters using Wi-Fi Protected Setup, or if you’d like to set more advanced options, you can use the configuration utility.
To install the configuration utility

Connect a computer’s Ethernet port to the PLW400’s Ethernet port using the provided cable.
