I live in an old house, with thick walls and a 'rambling' layout, and always had great difficulty in getting my wireless internet signal from one end of the house (where the master phone socket was) to the other (where my computer lives). So my wireless internet ended up with wires and aerials all over the place, which was hardly the idea...
Anyway, I thought I'd see if the Devolo Homeplug was any better, and it is! I wish I had never bothered with wireless, as the blue plugs were easy to set up and worked straight away with no problems at all. I am amazed how few people use this technology, as it works perfectly, with a far greater range than wireless ever managed.
I would recommend this kit as the perfect 'idiot proof' solution to creating a home network.
