Добречко
есть модем DSL-2500U, прошвка вроде последняя, настройки сбрасывал, на это линии Zyxel 630S (usb) работает стабильно
в info пишет о себе:
Device Info
Board ID: 96332
Software Version: RU_1.51
Bootloader (CFE) Version: 1.0.37-8.7

в логе сразу после включения и до бесконечности.

подскажите куда хоть смотреть?

ps: забыл написать. Avangard Komi Vorkuta

вскрыл, осмотрел. видимых проблем ноль.
конденсаторы в идеальном состоянии. даже намека нету.
модем в работе менее месяца, смена блока питания эффекта не дала.

еще идеи? плиз...

а фиг его знает, который провайдер в подарок дарил тот и пытаемся юзать

но до прошивки он отзывался

Board ID: 96332
Software Version: RU_DSL-2500U_1.20_03262008

а прошивка в него влилась эта:
RU_DSL-2500U_BRU_D_1.51_04232009

эффект одинаковый.

намек понял, в морг.
спасиб

Откатись на 1.50 (с PPTP) - она наиболее стабильная на плохих линиях. Настраивать роутером не советую. пока только бридж.
