Yes, alternative firmware does make a difference, line is stable, and no negative numbers, I'm running:
Firmware Version 3.8.9.7_VT4
DSL Version 579F17_A/B/C HW: A
Build Date/Time Dec 23 2019 14:13:36
This is on a BT line, so I don't know why Draytek recommend the _BT version if its not stable on a BT line?
