The Good Easy to set up and maintain; fast throughput; 128-bit encryption; 24-7 phone support.

The Bad Pricy compared to setting up a wireless network; adapters are a bit bulky and may block adjacent outlets.

The Bottom Line The Linksys PLK200 Powerline AV Ethernet Adapter Kit is one of the easiest ways to set up and maintain a home network that's fast enough to stream HD video content, but it's a bit of a strain on the pocketbook.

Linksys Powerline AV Ethernet Adapter series

Linksys--not one to sit out a networking category--has released its contender in the HomePlug A/V power line arena: the PLK200 Powerline AV Ethernet Adapter Kit. Power line technology lets you use your home's electrical system to transmit data signals, so if you're tired of dealing with wireless networks but don't want to have Ethernet cables professionally installed, a power line network is a compelling option. The PLK200 is the faster of the two HomePlug A/V-based adapters we've reviewed, the other being the Zyxel PLA-400 adapter, but the PLK200 is a little slower than the Netgear Powerline HD Ethernet Adapter, which is based on the HomePlug 1.0 standard. The adapters are priced on par with Zyxel's--about $100 per adapter, or $200 for the PLK200 kit. It's a potentially expensive network, especially if you put one adapter in each room of your house, but it's also far easier to install and maintain than a wireless network. Of the power line products we've reviewed recently, we like the Linksys offering the best for its combination of fast speed, large network potential, and generous support.

Power line networks use the electrical system as a network, with each electrical outlet serving as a node. Any Ethernet-equipped device (PCs, TiVos, and digital media adapters, among others) that's connected to a power line adapter is part of the power line network. The PLK200 adapters are based on the HomePlug A/V specification, which specifically addresses the quality of service (QoS) issues and higher throughput needs of HDTV and high-definition video streaming. The HomePlug A/V products are not interoperable with older HomePlug 1.0 (such as the Netgear Powerline HD adapters) or HomePlug 1.1 products, but they can share the same electrical network and run separate LANs. You'll need at least two adapters to start a power line network, and the PLK200 provides those. You can purchase additional adapters individually as well (model PLE200).

The Linksys adapters are 4 inches wide, 5.5 inches tall, and 2 inches thick. Three blue LEDs adorn the front, and a single Ethernet port sits on the bottom. The back of the adapter houses only the electrical prongs. Although the adapter is reasonably compact, it's too wide to use in a side-by-side outlet without blocking adjacent ports (as with outlet expanders that convert a single outlet to three or more). You may need to dig out an extension cord if you don't have enough space for the adapter. It'd be nice if Linksys provided a short extension cord for the adapters. (Zyxel's adapter uses a power cable, which makes space a nonissue, but Netgear uses the same form as Linksys and also fails to provide an extension cord.)
