Так что в последнее время у меня возникли серьезные проблемы с моим провайдером по поводу моего соединения.
Мой маршрутизатор D-Link 2750U сообщает о следующем затухании:
+------------------+------------+-----------+
| Attenuation (dB) | Downstream | Upstream |
+------------------+------------+-----------+
| | 365 | 183 |
+------------------+------------+-----------+
Мой провайдер говорит, что это неверно, и что ослабление в моей линии составляет ~ 18 дБ (я нахожусь в 27 км от моего интернет-обмена, что означает ослабление около 37,5 дБ или около того, как мне сказали).
Ниже приведена стенограмма журнала на моем маршрутизаторе за последний час:

Может кто-нибудь сказать мне, почему связь падает так часто? Я не слишком уверен, как интерпретировать информацию здесь ...
