After the performance level, I admit I was disappointed for a product CPL 500.
First test: 4-5 MB / s (I was 2-3 MB / s Wifi), while the box displays a green diode (supposed to guarantee me at least 10 MB / s) :-(
Second try, putting the CPL on a single dose, without putting any equipment on it.
I managed to climb to 7 MB / s over a socket, and even to 9 MB / s on a different outlet.
9 MB / s myself seems very acceptable but suddenly what interest to take a CPL box offering taken to put others above equipment, if it affects the performance ...
In the end, I preferred to take an ethernet cable (throughput between 60 and 80MB / s on large files) :-) and returning the product.
But if you do not have a choice (which is often the case), this certainly remains quality.
