Powerline networking is a way to extend your network using the electrical outlets in your
house. This works by adding a powerline adapter to your network. Setting up a powerline
network requires a set of powerline adapters plugged into each electrical outlet where the
network extension is needed.
The Linksys PLWK400 consists of the PLE400 Powerline 1-port Fast Ethernet and PLW400
Powerline AV Wireless Network Extender that lets you easily set up a powerline network in
your home. This article will guide you on how to create a network using your powerline
adapters.
IMPORTANT: To set up your powerline network, you should:
• Make sure you already have Internet access and a working 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 it to your wireless
router.

Creating a basic powerline network is now made possible using your plug and play powerline
adapters. This setup assumes that all the devices are located on the same floor of your house and
that you have an active Internet connection.
