5. Will HomePlug operate on different Circuit Breakers?
Yes. Circuit breakers do not affect performance of HomePlug devices, however the
signal will not pass through the power transformers outside your house.
6. Can Neighbors get my HomePlug signal?
It is possible for your immediate (next door) neighbor to receive residual signal from your
HomePlug adapter. Unlikely, but possible. To prevent your neighbors from hacking your
network, the best thing you can do is type a different encryption password into your device
when setting the encryption password. Note: All devices must have the same password to
be on one network. If devices do not have the same encryption password, they will not
be able to communicate with each other.
