Периодически обрывается интернет на этой модели, иногда сам поднимается, иногда приходится делать ребут, версия прошивки RU_1.20. Лог выдает такой:

Может кто-то сталкивался с таким? И может кто-подскажет где точно посмотреть версию прошивки и модель модема, ибо списано с наклейки на коробке.

1) вот прошивка ftp://ftp.dlink.ru/pub/ADSL/DSL-2500U_B ... 252008.zip
распаковываешь архив. Там есть 2 файла: default.cfg (конфигурации) и RU_DSL-2500U_1.40_12252008_cfe_fs_kernel (это и есть сама прошивка).
Сбрасываешь настройки модема, после чего в пункте Management / Update Software кликаешь на обзор и выбираешь файл с прошивкой. После этого нажимаешь Update software. Модем перезагрузится, во время перезагрузки ничего не делай - просто жди.
После перезагрузки модема приступай к настройке.
2) зачем ты выставил модуляцию ADSL2+? У тебя линия до ADSL2+ не дотягивает и скорость не превышает даже станарта G.dmt.
По-этому, идёшь в пункт Advanced Setap / DSL и убираешь все галочки кроме G.dmt.
После завершения всех настроек, не забудь в самом конце пунктов настроек выбрать Save/Reboot

Не помогло - логи такие :
