Прежде всего, Вам стоит разобраться с заземлением. При его отсутствии - перекусить земляной провод в кабеле (об этом тут уже неоднократно писали). Затем пересобрать статистику, посмотрим...

Какого типа розетка, в которую включён компьютер? Если обычная, то заземления точно нет (разве что оно прикручено к корпусу отдельным проводом).

Что касается кабеля, то это кабель, соединяющий модем с компьютером. Нужно открыть пластиковый корпус разъёма, которым этот кабель включается в модем (корпус из двух половинок, защёлкивающихся друг с другом). Сразу же увидите провод, припаянный к металлическому корпусу разъёма. Этот провод отрываете (перекусываете) и изолируете.

Компьютер подключен через сетевой фильтр VectorCOM , в розетку с заземляющим контактом. Фильтр , в свою очередь, включен в обычную евророзетку.
Перекусывать заземление у интерфейсного кабеля?
Извините за глупые вопросы, но я в этом деле новичек и не хотелось бы где-нибудь допустить ошибку.

[Technical Support]

Вопрос в том, есть ли заземление в этой евророзетке. Очень часто такие розетки устанавливают из соображений удобства, а заземления в них на самом деле нет.

В общем, отпаяла заземление, вот что получилось:

[Technical Support]

Скорее всего, дело не в заземлении. Давайте проведём ещё два эксперимента:

1. Попробуйте подключить адаптер питания модема (можно и компьютера тоже) в розетку напрямую, минуя фильтр VectorCOM. Если ситуация не измениться, то...

2. Попробуйте поработать с такой строчкой инициализации:

S210.7=1 S91=15 S55.4=1 +MS=12,,,,,,21600

Покажите статистику.

Вот статистика ( модем оба раза подключен без сетевого фильтра)

Ну что же, нужно оставлять строчку инициализации и так и работать. Фильтр вернуть на место - он, похоже, "не при делах".
