Как избавиться от разрывов связи по причине LINK DISCONNECT?

[Viper]

Идут постоянные разрывы связи с провайдером и не только с ним. АТС убогая аналаговая, максимальная скорость соединения - 33.6. О v.90 я и не мечтаю, хотелось бы только надежной работы, неважно с какой скоростью. Собственно затем IDC и приобретался. Провайдер свою вину в разрыве связи отрицает.
Вот статистика следующих 2х соединений:
На самом деле firmware 2.23, просто забыл заново определить модем.
