The Good The PLN3 Powerline AV Ethernet Adapter is easy to use, has two network ports, and comes with a service that allows for managing the power-line network via the Internet. The adapter is compatible with other HomePlug AV power-line adapters.

The Bad The PLN3 is bulky and has no power pass-through socket. The online service requires a live connection to the Internet and is only free for the first year.

The Bottom Line The PLN3 Powerline AV Ethernet Adapter is a convenient way to extend your network via the electrical wiring. However, its bulky size and lack of a power pass-through socket might steer away home owners with cramped power outlets.

The PLN3 Powerline AV Ethernet Adapter is the first power-line adapter we've reviewed in a long time (more will be reviewed soon), and like all power-line adapters, it offers a quick way to extend your network via the electrical wiring of your home or apartment building. This is a handy and effective solution for those far corners of your home where your router's wireless signal may be weak or nonexistent.

The PLN3 is rather bulky but it has two Ethernet ports--other devices usually have one port--to host up to two Ethernet-ready network devices. It also comes with an online service that helps monitor the power-line connection. The device is compatible with all HomePlug AV power-line adapters from other vendors; it costs around $90.

Note that you'll need at least two adapters to create a power-line connection. If you don't already have some at home, Plaster Networks is offering a deal by knocking off $30 if you buy a pair of the PLN3 adapters at a time.

Design and setup
The PLN3 Powerline AV Ethernet Adapter looks like a large power adapter for a small electronics device, such as a cordless phone or an external hard drive. It's about the size of two decks of cards stacked together. With this large size, it would be better if the adapter had a power cord, instead of just two prongs. As it is, the only way to hook it to the power is to snap it over a receptacle. This is a bad design as the adapter takes up a relatively large physical space and might even obstruct other adjacent sockets.

As the PLN3 doesn't feature a pass-through for the power socket, you will need a power strip in the far corner to extend the network. Note that the adapter might not work with all power strips or surge protectors because these devices generally degrade or block the signal from HomePlug AV adapters. In this case, the sure way is to plug it directly into the wall and make sure you have extra power outlets. To its credit, the PLN3 has two Ethernet ports. This means it can support up to two Ethernet-ready devices, such as a printer and a NAS server, at the far end. At the near end, where the adapter is hooked to a router, though, the second Ethernet port is redundant.

As with most other power-line adapters, there's really nothing to setting up the PLN3. For a typical power-line connection, say between the existing network and a device in the basement, you'll need two power-line adapters. The first adapter is to connect to the network by hooking it to an Ethernet port of the router (or the hub). The second adapter is connected to the device at the far corner. After that, you just plug both adapters into the power sockets. If the two locations share the same electrical wiring, which they do in most homes or apartment buildings, the network connection is now live. This whole process takes just a minute or two; we had no problem setting up the PLN3, and you won't either, most likely.

The PLN3 comes with a CAT5 network cable, which is needed to connect it to other network devices.

Features
What makes the PLN3 different from other power-line adapters is the included Plaster Networks Service that automatically updates the adapter to the latest firmware and allows users to keep tab of their power-line network over the Internet.

This service is easy to set up. You just need to access it by pointing a browser to service.plasternetworks.com from a computer that's connected to the Internet via the PLN3 adapter. You will then be prompted to register a new account (or log into an existing one). Then the new adapter will also then be recognized and registered automatically.
