Problemi con la connessione a internet...

[Markpd]

Salve a tutti! Mi sono iscritto sperando di vedere la luce dopo giorni bui...ho problemi con la connessione a internet, praticamente ogni 15 min compare un msg di errore che se ignorato fa funzionare lo stesso tutto per più o meno un ora poi si sconnette, se invece premo qualsiasi tasto tipo "ok" sulla finestra di errore salta direttamente la connessione.
Il panda dice che ho il pc pulito..idem ad-aware e spybot..voi che dite?
A voi il log:
