Napster: Apparently you can reset that no support warning by running the fritzbox recovery tool.
Also to change the Training SNRM you have to edit the cfg file through telnet.
Do you know if you can also alter the snr margin of a vdsl connection like we could do on adsl2+?
If yes, do you advise to do it after DLM has finished its work? (I don't want to get back to interleaved mode).
