The set "AVM FRITZ! Powerline 530E Set (500 Mbit / s, Fast Ethernet LAN, socket)" running at us good and stable without much setup! Unfortunately, we have only an average throughput of 21 Mbits upstream and downstream 57MBits. That's why I forgive only 4 stars. Otherwise, a top product! As most of the house of AVM ... the LAN cable laying effort you have saved it!
