More and more home theater devices are being introduced that offer "connected features," but many of them require an Ethernet connection, which isn't a common feature in most living rooms. One workaround gaining some traction is using powerline networkingplugging an adapter into an electrical outlet on one end and connecting to an Ethernet port on the other end. While its first iterations were disappointing, powerline networking, based around HomePlug technology, now can hold its own against wireless networking products, even if it still can't compete against 802.11n networks.
For data security, the DHP-303 uses the Triple Data Encryption Standard (3DES) and provides a energy-efficient mode that can detect when an adapter is not in use and power the unit down. The kit is priced at $139.99 and is available now to compete against the likes of Netgear's Powerline HD Plus Ethernet Adapter Kit.
