пользуемся DSL-500T. как купили, 2 месяца работал нормально, после чего начались глюки с авторизацией. Не может авторизироватся у провайдера. Входим в настройки модема, идем на страницу WAN, там ничего не меняя, жмем кнопку Apply, модем перезагружается и нормально начинает работать. Через некоторое время история повторяется. Питание подключено через стабилизатор.
Такое поведение наблюдается уже неделю. Иногда по 2-3 раза в день.
В чем дело?

прошивка не менялась, стоит версия V2.01B01T01.RU.20060620

1. Приведите лог устройства.
2. Абонентом какого оператора Вы являетесь?

было сделано сохранение настроек и перезагрузка, на что модем ответил

но, через 2-4 минуты, связь оборвалась снова. в статусе модема стояло Connected, однако с компьютера я не мог достучаться в инет. С модема пинги проходили на любой сервер в инете. на этот раз сохранение настроек и перезагрузка не помогла. установка dhcp на сетевой карте смотрящей на модем не помогла(может конфликт ip?). выключил все, включая комп на 5-6 минут. после этого все заработало. сейчас стоит динамика на сетевой смотрящей на модем. вместе с ней через хаб к модему в dmz зоне подключен адаптер ip телефонии, тоже на динамике .

Судя по логу Вашего устройства часто происходит разрыв ADSL соединения. Попросите провайдера посмотреть статистику ошибок на DSL порту DSLAM, к которому Вы подключены.
После "тонкой настройки" профиля DSL порта (настраивается технической службой провайдера), можно будет перейти к диагностике PPP соединения.
