Добрый день! Столкнулась с проблемой на 2540 U.
Схема подключения , в подъезде дома установлен шкаф . В котором поставлен Dlink 2540 U. В него воткнута линия и 3 клиента. Прошивка :RU_DSL-2540U_1.00_01112008. Проблема заключается в том что периодически "модем подвисает". После того как на DSLAM перезагружается инженерами порт. Модем снова работает ,до следующего "подвиса". Для полноты картины прилагаю логи :System Log
