I am looking for information on Ethernet power line adapters. In particular, I am curious if anyone has had trouble with them working across the two legs of a 120/240 VAC system, as sometimes occurs with X10 systems? At the other extreme, has there ever been an incident where a second residence has been able to access the network of the first residence because they were attached to the same pole transformer secondary?
If this is the wrong group to post this in, my apologies, but it seems that people that understand X10 problems, and also used Ethernet power line adapters, would also have a good feel for the performance of Ethernet power line adapters and their weaknesses
