I installed four powerline adapters in my apartment in a huge apartment building. I noticed that in the appartment two stories above me, the power line adapter is still able to connect to the other ones!
Is there a way to set up a password or other kind of security so that I don't share my internet with other 44 apartment units?
Normally the signal should stop at the power meter, do I have the right to force my electricity company to fix it?
