Powerline networking

Any possible problems?

There are a few things you need to be aware of, however. Powerline, like Wi-Fi, is affected by distance and data throughput will drop when you try to network power sockets that are a long way apart. It is also affected by the use of things such as extension leads and surge suppressors, which tend to filter out the network signal, so avoid using them where possible. It also works best when the adapters are on the same ring mains circuit.

What do I need to buy?

Powerline network adapters are available from several vendors. Basic models should conform to the HomePlug 1.0 standard, an industry specification drawn up several years ago by the major players in powerline networking. Devices such as the Netgear XE102 (www.netgear.co.uk) will be fine for setting up a powerline network even if the PCs you want to connect use different operating systems.
If you want to send video content across your network you'll be better off looking for devices that comply to the newer HomePlug AV standard, which offers greater bandwidth. Netgear's HDXB101 operates at up to 200Mbps, as does the dLAN 200 AV from Devolo (www.devolo.com). Some devices, such as the Netgear WGXB101 can also connect to Wi-Fi networks as well as powerline networks. Other powerline vendors include Solwise (www.solwise.co.uk), eConnect (www.econnecthomeplug.co.uk) and Dynamode (www.dynamode.net).
