There could be several floors significant improvements in data transmission in a stable operation achieved especially for steaming on TV (figures Altinstallation in brackets):
Client PC Client to Internet box: 189 Mbit / s (171 Mbit / s), dLan 1200+ to dLan 650+
Client PC to client TV: 265 Mbit / s (97 Mbit / s), dLan 1200+ to 1200+ dLan
Client PC Client PC-UG: 168 Mbit / s (163 Mbit / s), dLan 1200+ to dLan 650+
Client PC Client Notebook: 278 Mbit / s (487 Mbit / s), dLan 1200+ to dLan 500+
Client PC to client Multimedia Studio: 193 Mbit / s (154 Mbit / s), dLan 1200+ to dLan 500+.
Since thus the intended improvements have occurred, I am satisfied with the 1200+ devolo dLAN.
