Здравствуйте!
возникла проблема с настройкой и эксплуатацией модемов вашей фирмы.

Из партии закупленных устройств неполадки наблюдаются со семи экземплярами.

Симптомы: Первые полчаса модем работает корректно, потом невозможно зайти на интернет страницы, идет редирект на модем, не пингуются узлы по имени хоста, только по ip. Если зайти на модем по telnet и попинговать с него, то все нормально. Днс пробовали
прописывать и динамические и статические, это никак не повлияло на конечный результат.
Судя по информации с форумов, это как-то связано с кэшируещем днс сервисом в самом модеме, который нельзя отключить (или можно?).

На один из модемов поставили самую последнюю прошивку с офф. сайта, ситуация не изменилась
