A best bet is the factory-refurbished Western Digital Livewire AV Powerline Network Kit, model no. WDBABY0000NBK-NESN, for $49.99 after the above discount with free shipping. That's $14 under our August mention of a new unit and $10 less than the lowest total price we could find for a new one today. (Most stores charge $79 and up for a new unit.) This wired network solution uses your home's AC powerlines to carry a broadband Internet signal. It allows you to network your router with up to seven Internet-connected devices such as computers, TVs, game consoles, media players, and network storage drives.
