[Technical Support]

Поведение модема вполне адекватно ситуации на линии. Линия нестабильна, и оба модема "бегают по скоростям". При этом Ваш модем ухитрился "жить за счёт" пересогласований удалённого:

Renegs Issued/Granted........ 34/71

(сам запрашивал вдвое меньше пересогласований). В общем, линия не лучшая, но ситуация вполне сносная. Ничего настраивать не нужно.
