поднять скорость на 5614 при хорошей линии?

[Vadim]

Есть хорошая линия, есть хороший модем - но почему скорость такая маленькая?!

После замены прошивки на 2.23 - модем работает на 44000 с постоянными движениями вниз-вверх (тормозит и раздражает). На старой прошивке 2.14 - стабильной была работа на 46-48 тысячах с CPS около 5,0-5,2 кБ/с.

Буду очень признателен, если кто подскажет чего-нибудь в настройках, чтобы сделать работу мордема стабильной на высоких скоростях:46-48 тысячах.
