While WiFi is great for a lot of things, but there are instances where it isn’t the best solution for home networking. Perhaps you live in a palatial mansion that outstrips the range of ordinary WiFi technology, or maybe you live in a drafty Scottish castle with five foot thick walls that completely blocks all your signals. Or maybe every other sod in the near vicinity already has a WiFi router clogging up the airwaves. Whatever. There’s a way around it that works really well called HomePlug AV, which uses your mains sockets to carry your network. The trouble so far has been that you always have to buy a costly set of HomePlug AV adapters – one for each of the devices you want to plug in and one to plug into your router / hub.
