Hello There! After initial skepticism, I have the PL 546E but ordered and unpacked before about 15 minutes. Since I have been in operation 520, was also this adapter within minutes "online" and I could see that he had built up in the region provided its own Wi-Fi network. Just as I had imagined. The wireless devices in this area are now connected to the Powerline and everything works perfectly!
Just be patient, you have to only have when you leave the radio area and the radio range of Fritz enters. It will take 1-2 minutes until the unit "has re-registered.
For the moment I am very happy; I'm now in the rooms where I previously also with Repeater inadequate WLan got finally a super stable WLAN network! Perfect (if it stays that way)!
