Добрый день.
Пользуюсь широкополосным интернетом вот уже полгода. Но скорость что-то не очень устраивает. После подключения установили скорость на модеме 7168/716 Кб/с. Но в реале намного ниже по данным AIDA64 скорость входящего 250-300 КБ/с (~1600-2400 Кб/с) исходящего 4-6 КБ/с (~32-48 К/c). Параметры линии

Что означают параметры линии
noise margin upstream: 14 db
output power downstream: 19 db
attenuation upstream: 14 db
noise margin downstream: 14 db
output power upstream: 12 db
attenuation downstream: 26 db
Каковы их значения для нормальной работы.
Спасибо!
