good flow but disconnects occasionally

This kit 500Mb / s was installed without difficulty. Good point on the product design with the postponement of the power outlet and reasonable dimensions for installing the housings on most of the catch. The monitoring software is very well thought out. The flow rates were satisfactory with 140 Mb / s measured. As against the boxes disconnect from time to time, which is corrected by a simple reset. This may be related to my wiring but when in doubt, I point out. To solve this problem I upgraded the firmware but it changed nothing. One point to note for this procedure: given that the Powerline network does not allow this operation, connect the boxes one by one on the main computer, which is not very convenient.
