2740 по 2-3 раза в час отрубается. Пишет аутентификация не пройдена, потом pppoe down, reboot не помогает только перегрузка кнопочкой сзади. Прошивка последняя.

Model Name: DSL-2740U
Time and Date: 1.01.2000,00:07:24 Sat
Firmware Version: DRU_2.35

Пока не ставил последнюю прошивку все было отлично!

ТЕХ.Поддержка ВООБЩЕ Тут РАБОТАЕТ???????????????

Тут всех колбасит от этого модема, не получилось у меня
летом купить ASUS вот теперь тоже мучаюсь, до этого был DSL-2600,
поменял для 11.n c тем тоже год был гемор пока прошивки менял и
тоже инет отваливался постоянно, так что эта заноза отличительная
черта D-Link - покупаешь будь готов к проблемам
