NP285 - Can my neighbour receive my HomePlug signal?

It is possible for your neighbor to receive your HomePlug signal between two adjacent homes. To prevent this from happening, please enable the 56-bit DES security encryption on your HomePlug Device. To do that, you must run the HomePlug Configuration Utility on each HomePlug device in your power line network. This will only allow computers with the same security password to be able to receive information.
