I got nowhere answers the simple question of whether this system works in a rented apartment in an apartment building. So clear that is not fact. Whether "experts" of Kabel BW, Germany cable or telecom, no one could answer me this question. Even in relevant forums this simple question is not treated. Maybe the question is so simple and obvious that I just do not know the answer.
Anyway, it works and still work! The apartment has a dedicated circuit (that usually is the case) have with private distribution box in the apartment. TP-Link plug 1 via a LAN cable to the router and then plug it in. TP-Link 2 stuck in the room of your choice into an empty socket. TP-Link 2 using the LAN cable to connect to the desired device or switch. DONE! RUNNING! I have a 150 M / bit line. The receptacles concerned are 12 feet apart in different rooms. It come 140 M / bit at the terminal.
Bye Bye W-Lan! Bye Bye crappy download speeds! Bye Bye Your specialist idiots of XYZ, which can not even answer such a simple question!
I recommend the TP-LINK TL-PA4020PKIT AV500 Powerline network adapter due to the integrated sockets and two LAN ports. Have purchased in the offer for 46 euros, Ste Amazon.
