I had a line problem a few months ago (literally). After months of intermittent HR issues, the line completely failed. An OR engineer was dispatched and it was fixed, however since then my line is stuck at 67/19, when the attainable is ~74/20.
I know that DLM takes time to reset, but months having passed, I think something's wrong. The router is up and stable along with the line.
I asked my ISP (Zen), and they were unusually unhelpful.
Anything I can try?
