Ухудшение связи по времени суток

[Максим]

Что-то странное твориться. Обычно скорость ~28800-31200. А тут зашел сразу после 23.00 Ивот он выдал:

В модеме установки:
+ms=11,,,,,,21600
S13.2=1 S13.7=1 S36=4 S17=64 S55.4=1 S50=15 S103=25 S106=20 S107=40 S108=25 m4

Может, что подправить можно? Подскажите.
