Speedport Entry 2i internet hiba

[Jocoo]

Sziasztok!

Két hónapja vezették be a 30Mbps-os internetet, akkor 14-15Mbps volt a max. sebesség. Egy hónapra rá 10Mbps-os volt, pár napja pedig már csak 2,5Mbps-os az internet és kb. fél óránként egy pillanatra lecsatlakozik.
Szerintetek mi lehet a probléma?

Itt egy kis LOG:
