Ciao a tutti,
ho un problema che mi sta tirando matto. la mia scheda ethernet realtek GBI molte volte, sotto intenso utilizzo, perde la connessione e per farlo "riprendere" devo fisicamente staccare e riattaccare il cavo.

dalla presa ethernet esce un cavo che entra in una powerline netgear.

le situazioni in cui normalmente succede il problema sono:
- scaricamento da torrent. (molto frequente)
- scaricamento di file da parecchi giga (notato una volta)

ho già disattivato modalità di risparmio energetico e modificato le impostazioni della scheda, che già ha l'ultimo driver disponibile per windows 8. qualcuno ha qualche dritta per risolvere la questione?

allego un po' di log che possono magari illuminarvi, io non so da dove partire!

Grazie a tutti!
