Whilst turning WiFi off at night may hide (I'm still very suspicioue that your powerline units are the source of the leak) most of the evidence that some-one else has access to your network, this does not solve this issue. My advice is to find the source of the leak and stop it by using improved security.

Yes I will look for an app to control security of the powerline, Windows has it but I have Ubuntu Linux, will see what there is, I would think there must be something. Cheers Baldrick.
