I've just installed a Devolo network plug in a remote part of the house that hates wifi signals. This takes the internet signal from the router via a plug that goes into the mains. The signal is then picked up at another plug, also from the mains. I've just read the manual and it recommends setting a password on the network 'to avoid unauthorised access'. I'm not talking wifi here, but the dLan. It also states that 'the electricity meter does not provide a physical barrier to the network signal'. Does this mean that in theory a neighbour with some technical knowledge could use this signal over his mains too, or am I being paranoid?
These do work very well, by the way.
