hi,

if you have fibre connection and effective bandwidth varies between 2-10MB/s than:

  1. you may have ISP ONT problem
  2. very unstable ISP service
    and likely your router cannot keep up if SQM is used. bear in mind SQM does require CPU, low end devices have "just enough" CPU usually as networking is covered by chipset.

alos check this thread CAKE w/ Adaptive Bandwidth , might help to address bandwidth variability.

but first please post what @moeller0 asked for to see what is happening sqm wise.
