I've purchased network adapters that run over power lines, but I get no signals. What might be the problem?

A. I recently purchased some NetGear HomePlug adapters that let you connect different rooms of a house with Ethernet by using the power lines. (You can find more information about the units at http://www.netgear.com/Products/BridgesAccessPointsandExtenders/PowerlineWallPluggedExtenders/XE102.aspx?detail=Specifications.) However, after connection I got no connectivity. After researching the problem, I discovered I had plugged the adapters into surge protectors, which effectively strip out surges, which the network signals are! To resolve the problem, connect the adapters directly into wall sockets--not via a surge protector or plug extender. You should also enable encryption on the devices if sensitive data is being transmitted because the range of the networking signal might be further than you think.
