8       Locked   QAM256      152       6952000        4.1 dBmV   40.3 dB

Signal/Noise ratio for upstream is:

Channel	Lock    Modulation   Channel   Symbol   Freq   Power
        Status               ID        Rate
1       Locked  QAM64        1         5120 Ksym/sec   45.5 dBmV
2       Locked  QAM64        2         5120 Ksym/sec   47.0 dBmV
3       Locked  QAM64        3         5120 Ksym/sec   47.0 dBmV
4       Locked  QAM64        4         5120 Ksym/sec   47.5 dBmV

I ordered 120MBit/s, but speed according T-Online speedtest is as follows: cablesurf-speed1

I attribute the drop from the bought speed to peering between Telekom and Cablesurf.

Checking my Unitymedia connection with T-Online speedtest gives: unitymediaspeed2
