В последние пару месяцев D-link 500T при подключении с интернетом через несколько минут разрывает соединение. При работе с бесплатным ftp-серевером работает без разрывов соединения. Модем приобрел почти 2 года назад и до этого времени таких проблем не возникало. Помогите чем сможете. Заранее благодарен за помощь.

Прошивка V3.02B01T01.RU.20060818

что в логах пишет ?

что в параметрах линии ?

STATUS -> ADSL

ADSL Status

ADSL status shows the ADSL physical layer status.

ADSL Firmware Version: 5.00.04.00 - 5.00.03.00 - 5.00.03.00 Annex A - 01.07.2b - 0.52
ADSL Software Version: V3.02B01T01.RU.20060818
Line State Connected
Modulation ADSL_2plus_AnxM
Annex Mode Annex A
Max Tx Power -38 dBm/Hz

Item Downstream Upstream Unit
SNR Margin 16 37 dB
Line Attenuation 26 13 dB
Data Rate 6141 510 kbps

В логах я не разбираюсь, их там 7 страниц. Если надо, могу скопировать

параметры линии неплохие, скопируйте логи

возможно проблема в том что
Modulation ADSL_2plus_AnxM

провайдер не поддерживает Аннекс М
попробуйте поменять модуляцию в Advanced - ADSL

ADSL2+ MultiMode Except AnnexM (если используется АДСЛ2+) до 24 Мбит
ADSL2 MultiMode до 12 Мбит
ADSL (MultiMode) до 8 Мбит

Вот логи после перезагрузки модема:

При смене модуляции с ADSL2+ (MultiMode) на другую лампочка ADSL гаснет и модем приходиться перезагружать.

логи хотелось бы увидеть не после перезагрузки
а после дисконнектов, после перезагрузки неинформативно
