В общем ситуация следующая. Подключен к провайдеру ADSL. Модем DSL-2520u. Проблемы следующие
1) По полдня лампочка DSL даже не мигает. Когда мигает, обычно долго ищет сигнал.
2) Частые обрывы связи. Самое стабильное чего удалось добиться час работы
3) Плохой пинг до яндекса, часто выскакивает сообщение - превышено время ожидания запроса и тд. Пинг скачет, может быть 60 мс а может и резко до 300 подскочить.
4) Показатели скорости на speednet крайне низкие - по давнлоаду в среднем 0.5 mbps по аплоаду вообще 0.05 притом что по тарифу должно быть стабильно 1024 kbit/ 512 kbit. Тестил на разных серверах на каждом по нескольку раз, антивирусы, торренты и прочее что могло бы жрать сеть выключено
5) Скорость плохая и скачет, может от 10 кбайт в сек до 100 скакать (последнее редкость и наблюдал всего пару раз), бывает что инет по минуте и более простаивает а потом снова начинает работать без обрыва коннекта.
Сплиттеров и фильтров пока не стоит, в доме 2 телефона 1 радиобаза и другой обычный от линии. Пробовал отключать телефоны - ситуация сильно не меняется.
Ниже привожу статистику ADSL модема. Соответственно, подскажите, что и как, где искать проблемы и с чего стоит начать?
