We live in a house with a relative. new professional installation and use devolo dLAN 200AV. The installation of the phase coupler (in the fuse box acc. To instructions) brought bottom line nothing. Clearly, the capacitive coupling of the lines is also as already more than adequate. For comparison, the output from Devolo Informer data transfer rates (before / with / after) for 3 different up / down links: 67 53 77 32 32 51 41 26 39 33 32 45 24 17 28 34 29 39 As you can see, the rate "with coupler" (middle row) rather slightly below that of "without coupler", however, is the range of variation rel. high. It may be that there are extreme circumstances where it brings what, but not with us. Not like me also has: - The connection wires do not have ferrules, which in practice (is yes mostly not installed by qualified personnel) probably sometimes for omitting leads (poss security risk.) - The words "that it is not a toy and therefore no CE marking has". This is probably the excuse that it does not get CE mark from "other reasons". The CE applies for so much in the product safety, not just toys. - May burst and the notice that the module is not very reassuring. I'll send it back.
