Hust... hat wohl grad jemand ein Schalter umgelegt, hatte gerade im Speedtest 46 Mbit/s im Upload.... oder war's ein Leistungsloch....?! 
Hast du die möglichkeit die Fritze mal direkt an den HÜP zu klemmen ?
Bei QAM16 im Upload geht halt nicht wirklich viel, sollte aber in einem "gesunden" Netz auch nicht bei 16 sein.
in some initial testing, when using the TaFDM feature between SC-QAM & OFDMA channels, it has been observed that the throughput varies depending on the set of channels in use. In one example configuration, there was one 40 MHz OFDMA channel and 4 SCQAM channels in between as per above diagram. The throughput for the time with OFDMA-only portion in use is the highest, the SCQAM-only is the lowest and when they are time sharing the throughput is somewhere in between. To achieve a good OFDMA throughput, consecutive spectrum is needed without the use of SC-QAM channels. The CMTSs tends to schedule OFDMA traffic first in the OFDMA area before it schedules OFDMA bursts in the TaFDM area. If that area is in the lower part of the US spectrum, then the OFDMA also has to deal with the ingress noise which is more typical at the lower frequencies up to 20 MHz. Some operators have turned off TaFDM as that feature is not quite mature on the CMTS implementations and has not gone through enough CMTS-CM system debug.
hatte doch schonmal aus einem Dokument diesbezüglich zitiert:
