Better than my 500 Mbit another brand

These Devolo (I took 2 packs so I 4 CPL) are currently very good. Of course the transfer rate is never at the top (for me) but the ones I found most stable compared to the competition.
Personally, my speeds exceed the 100 mb / s which allows me to have HDTV.

The software provides with CPL is great and allows you to make updates and see the flow.

By cons little trick if you have an adapter in your room for example ... One of the LED lights up and blinks every xx seconds if there is nothing plugged into the adapter. The management software must be launched and you can disable this :) diode.
