Ethernet Powerline dapter

Here's a handy way to create a 'wired' network without installing a lot of new cabling.

TP-LINK's TL-PA251 powerline adapter takes advantage of your home's existing electric wires to transfer data while transferring power. That means, with no additional wiring required, users can simply plug the TL-PA251 into existing power sockets and establish networking infrastructure in a flash. With an additional integrated power socket, it solves a common powerline problem where power sockets would be blocked and thus unusable for other devices. Adopting a totally new product design, the TL-PA251 enables high data transfer rates of up to 200 Mbps over a home's electrical circuit for up to 300 metres with an Auto Power-Saving Mode that reduces energy consumption by up to 75 %.
With it's integrated power socket, the new TL-PA251 provides real convenience for your home network. The integrated power socket allows an additional device or power bar to be connected to the adapter as though it were a normal wall socket. This ensures that even with the TL-PA251 plugged in, users won't need to worry about disconnecting their internet to get power for their other devices.
NB: They come with a 3-pin plug, and are only suitable for the UK Mains.
