DLM is killing my internet experience. Despite putting me on max speeds profile, MY ONLINE GAMING is ruined. How can I get this changed. Can my noise margin be increased significantly so my connection becomes more stable - i dont care about max speeds and Im not gonna stop complaining till something is done.
the simple solution is a few resets and DLM will see line as unstable and take action by increasing your noise margin and decreasing your speed
unlike adsl there are no manual adjustments as DLM all automatic for fibre
The OP would appear to have FTTC, not ADSL
However this thread seems to contradict that https://community.bt.com/t5/BT-Fibre-broadband/How-to-calculate-SNR/td-p/2060601
