И неужели 2814 лучше 5614?

[Андрей1979]

Здравствуйте!В последнее время с интересом слежу за форумом и вот решил обратиться к вам за помощью.Проблема следующая:был модем 2814 BXL/VR+, особых проблем вроде как не было,месяц назад приобрёл 5614 BXL/VR+,и вот началось:то выкидывает через 5-10 минут,то ретрэйны покоя не дают,в общем мучение полное!Живу в провинции,до провайдера 100 км, по ВОЛСу правда.Ещё интересная деталь:если на старичке 2814 время эха было 15-16 мсек,то на 5614 выросло на полпорядка до 70-72мсек.Хотелось бы узнать,в чём причина,может дело в координатке местной, и что посоветуете сделать?Заранее благодарен!Ниже привожу для сравнения статистику обоих модемов.Inpro IDC Modems Diagnostics, Version: 1.1.4.39

Давайте для начала попробуем Вас успокоить: IDC-5614BXL/VR+ превращается в IDC-2814BXL/VR+ путём прописывания в строке инициализации команды:

+MS=11

Пропишите эту команду и убедитесь, что новый модем работает точно так же, как и старый. После этого будем разбираться дальше
