Hi All,
I had FTTC installed a couple of months ago (HG633 router), upload sync speed started off at 8.45Mbs now sits at 6.00Mbs for last few weeks, however the noise margin is 15.9dB. The line seems stable doesn't dropout . My understanding is that the DLM aims to have a 6dB margin so should be edging this speed back up over time?
