I have the problem that no incoming call numbers be displayed Konstelantion with the Nano and Fritzbox 7390. Have 3 of those things and at each of this phenomenon ... Fritz is currently!
TP-Link wrote that it would not be up to you and said that the AVM can not come from you!
So there probably none to blame!
I make the Nano from the LAN from, go without problems!
Have now be put on VoIP analog telephone and since then the caller ID goes again!
But otherwise makes the Nano what to ... It transmits the data from the Fritz box to the PC!
Have me today times the 530e Fritz Powerline kit ordered ... I test the times, if there are still problems there!
Could be really putting together since not really fit.
