Проблема следующего характера:
Периодически зависает данный чудо девайс DLINK DIR 300 NRU B7. Проблема не зависит от операционной системы, от вида подключения, проводное или безпроводное. Ему вдруг просто надоедает работать. Как правило это происходит если dlink не отключать от питания несколько дней, а после при включении компьютера соединение с маршрутизатором не устанавливается помогает только ребут по питанию длинка. Наблюдается данная проблема как на ОС Windows7 так и на Ubuntu 12.04. На маршрутизаторе установлена прошивка 1.4.8.
На маршрутизаторе настроено:
На wan: static ip
На lan: dhcp-server отключен.
на wifi: режим b/g/n, аутентификация:wpa2-psk, шифрование: aes, привязка мас адресов к ip
В межсетевом экране DMZ.
Возможно ли данную проблему решить.

Здравствуйте. Вы можете снять логи перед зависанием? Например, настроить их сброс на один из компьютеров.

Полезные настройки

Да я попробую настроить сброс логов перед зависаниями. Возможно сегодня вечером. Как только это сделаю отпишу и скину логи.

Добрый день я настроил сбор логов на удаленный хост, сегодня проблема с зависанием повтарилась. Скидываю

Первое янаря это время ребута, также не коректно работает ntp клиент, точнее время на маршрутизаторе отстоет на час либо спешит. при выставлении +2 на час отстает.

У меня зависал периодически, подключен был круглосуточно; чаще всего зависал ежедневно или дважды в день, реже работал 2-3 дня.
Прошивка на последнюю версию не спасла положение. Только выдёргивание блока питание спасало до следующего раза.
Мучался месяц. Прочитал весь форум, сам даже писать не стал - у всех проблемы.
Ждал прошивку после 1.4.8, ждал три месяца, вчера отнес в магазин и забрал деньги.
Пару месяцев пользуюсь DIR-632, за это время пару раз затупил, но это просто несравненное счастье по сравнению с DIR 300 NRU B7, и даже с Асус, который я также передергивал пару раз в неделю.
