Verbindungsprobleme Und Ne Menge Geblockte Packets

ich hab seit kurzem das problem, dass meine internetverbindung immer wieder für kurze zeit nichts durchlässt, dann wieder funktioniert, dann wieder nichts durchlässt usw.
ich habe bereits mal meine netzwerktreiber aktualisiert und auf meinen router (d-link dgl-4300) die neue firmware aufgespielt. hat aber nicht geholfen.
ich hab jetz tmal n blick in die logs meines router geworfen udn da sieht es so aus (die lsite ist nu ein ausschnitt):

weiß jemand, was das ist und was ich da machen kann?
also die FIN:ACK dinger scheinen vom googlebot zu sein, die sind also nicht weiter schlimm, aber die ganzen geblockten eingehenden verbindungen wundern mich doch.
