The Good The Panasonic Ethernet adapters are easier to set up and configure than a wireless home network, and you won't have to pull Ethernet cables through the house. The throughput rate is more than fast enough for sharing a broadband Internet connection, and it should be sufficient for transmitting high-definition video content.

The Bad Even though you don't have to run cables through your house, you'll still have an unsightly mess of cables around each adapter, especially if you're using a hub/switch to connect multiple devices to a single adapter.

The Bottom Line If you're not on the wireless bandwagon, you don't have to forgo a home network or pay to have a network professionally installed. With the Panasonic HD-PLC power-line Ethernet adapters, you can have a wired home network up and running in minutes.

Despite the prevalence of wireless home networks, some people just aren't ready to cut the cord. Maybe you've already tried a Wi-Fi home network and found it too much of a hassle to set up and maintain, or perhaps Robert Vamosi's Security Watch column has you running for the hills and swearing allegiance to the Luddite way of life. If either describes you, then power-line Ethernet adapters are worth looking into. Panasonic's power-line offering--the HD-PLC Ethernet adapter--is dead simple to install and use. On the downside, the adapters aren't cheap; if you have a lot of devices you want networked around your house, the needed adapters could run you hundreds of dollars. And despite the fact that you don't have to pull cables throughout your house, you'll still have to deal with an unsightly tangle of wires around each adapter.

Power-line technology uses a building's existing electrical system as a conduit for electronic data. The wall outlets serve as connection points, or nodes, on the network. Transferring data over the electrical network doesn't interfere with your electricity because data is transmitted at a higher frequency than electricity. Power-line systems involve connecting your router into the master adapter via a standard Ethernet cable and plugging that adapter into a wall outlet. Network clients are plugged in to additional adapters, which are also plugged in to wall outlets; basically, anywhere you have a wall outlet, you should be able to connect to your network via an adapter. Some power-line adapters, such as Netgear's WGXB102, mix Ethernet connections with wireless capability by rolling a wireless access point in to the wall-plugged unit, letting you extend the reach of your wireless network anywhere you have an electrical outlet. Panasonic's adapters don't incorporate wireless technology but still allow you to easily extend your network.

Panasonic's Ethernet adapters are about the size and shape of a bulky point-and-shoot camera. The only components are a power port, an Ethernet jack, a master/terminal switch, and a setup button. Unlike the petite Netgear XE102 Powerline Adapter, the Panasonic HD-PLC uses a power cable to connect to the wall outlet. It won't block an additional outlet, but this does mean you'll be faced with yet another cord.

Setting up Panasonic's HD-PLC Ethernet adapters couldn't be easier. The best way is to begin with the starter kit, which comes with two preconfigured adapters, because you'll need at least two to create a network. Simply plug in the Master adapter (so labeled) to a wall outlet near your router. Then plug in the second Terminal adapter anywhere you want to have access to your network. At this point, the three LEDs should light in different combinations to indicate whether the adapters are set up correctly (the included installation guide outlines the meanings of the lights). If all is set up correctly, the final step is simply to connect your equipment, such as PCs, networkable printers, and NAS hard drives, to the adapters via Ethernet cable. Unfortunately, the adapters don't come with Ethernet cables, a shortcoming we can't forgive, as Netgear's XE102 adapters come with a six-foot cable and even wireless routers come with an Ethernet cable for connecting the router to a modem.
