Being equipped with several devolo, I resolved to acquire that one to replace one (which will not have lived more than a year!) Without waiting for a solution of the service which, based on reviews here Moreover, does not shine by its reactivity. Recognition by the Cockpit software was no problem and the adapter worked correctly during ... 15 minutes. Moreover, a disturbing hiss escaped from the adapter. So I unplugged and reconnects the few minutes later, but nothing to do, obsolescence had to be programmed in minutes, not months ... If devolo is (was?) A pioneer or market leader PLC, it seems that they are not living up to their reputation!
