This is the 7th Eaton box I installed to protect TV and powerline network. Obviously this is the storm that will be the final judge of peace. But for the operation of the network, it works beautifully, without any flow alteration. One extension cords feeds 2 computers, a network printer and all associated peripherals. Another feeds TV + VCR + sound as well as stereo (ancient and powerful) with multiple elements. Without any problems. WARNING: when installing PLC boxes, this does not always work on the first outlet tested: do not blame the CPL housing or power strip Eaton; you first have to question the electrical installation. Indeed, in a little old facilities, the links can follow a circuitous route through multiple intermediate connections invisible but which degrade the bandwidth needed to CPL. I 2 separate households, one with a recent wiring and the other with an original installation. With the recent installation, everything worked the first time on all outlets. With the old system, it took in every room look good decision, I have always found, further proof of the proper functioning of both the CPL boxes and Eaton Strip. When taken (in fact it is the path taken between 2) is malfunctioning, you can not see it right away, because the cuts are random. After spending the time, the most effective test that I found is this: launch an internet radio show and record the line with suitable software for several hours. By analyzing the file its product, then it is detected infallibly cuts and their duration, as recording continues to receive whatever the line. It can also copy large amounts of data between two remote computers, but stops at the first crash, whatever its source (line or data) and proof of origin of the malfunction is then less clear.
