Western Digital WD Livewire doesn't look like other network powerline adaptors such as the Devolo dLAN 500 AVplus. For a start, it doesn't plug directly into a wall power socket. Instead, it's a small box that connects to the power socket via a cable. It's not as elegant a solution as other powerline adaptors, especially ones that have integrated follow-through sockets - which means you don't have to sacrifice a socket when installing them.
However, it does give you a bit more flexibility on where to place the unit, since the power cable is long enough to tuck the Western Digital WD Livewire out of sight. It was especially useful for installing the Western Digital WD Livewire in awkwardly-placed power sockets where we've had trouble using the bulkier powerline adaptors.
The unique design also offers another advantage that is absent from many of its competitors - both units come with four 10/100 Ethernet ports, where most only have one, enabling you to connect a number of wired devices to the powerline source. This can result in quite a bit of money saved, since it spares you from buying either additional adaptors for each device or from having to buy expensive proprietary wireless dongles - smart HD TVs and original Xbox 360s are particularly bad for this.
Network speeds were very good, averaging around 126Mbps with plenty of bandwidth for streaming standard definition movies from one PC to another. High definition streaming was less smooth, so a faster powerline adaptor focusing on media streaming is going to be a better buy.
For decent and consistent network speeds, coupled with ease of use and some good features, the Western Digital WD Livewire is a very good powerline adaptor kit.
