The Good Dead easy to setup and maintain; 128-bit AES encryption; utility offers security features, such as password protection; QoS for latency-sensitive applications; generous warranty period.

The Bad Pricey; slower throughput than the competition.

The Bottom Line The Zyxel PLA-400 is a compelling alternative to a wireless home network, but the competition offers faster throughput for about the same price.

If your current 802.11g network can't cut the mustard for streaming HD content or you're simply tired of wrangling a wireless network (maybe your house isn't well suited to it), you have another option: power-line networking. The Zyxel PLA-400 HomePlug AV Ethernet Adapters let you use your home's existing electrical system to create a data network that can support enough throughput for demanding applications such as HDTV and VoIP. With each adapter costing about $95 (you can find them online for less) and each network requiring a minimum of two adapters to start, though, it's not an inexpensive solution. And in our Labs' test, we found the PLA-400 to be slower than a similar product from Netgear.

Power-line networking lets you take advantage of a preexisting home network--your electrical system--to transmit data between networked devices. Each electrical outlet serves as a node on the network and any device, such as a digital media adapter or a PC, that's connected to the electrical system via an adapter is part of the LAN. Zyxel's previous iteration of the product, the PL-100, is based on the HomePlug 1 spec. The PLA-400 device is based on the new spec--HomePlug AV--which specifically address the need for QoS for latency-sensitive services such as HDTV and VoIP (HomePlug AV is backward-compatible with HomePlug 1). The theoretic throughput of HomePlug AV products is 200Mbps, but real-world performance is pegged at around 100Mbps.

The Zyxel PLA-400 uses the same design as its predecessor, the PL-100. The compact silver-and-black brick houses four LED indicator lights on the front and a power port and an Ethernet port on the back. The bottom of the adapter has two holes for wall-mounting the device.
