In attesa avere in prestito il fritz, ho già montato il modem-bridge Zyxel VMG4005-B50A e ho tirato fuori questi log:

============================================================================` !
è normale che dopo 2 minuti di uptime ci siamo 32k FEC?
Intanto mi aggancia 15Mb di up rispetto ai 12Mb del modem Poste.
Un'altra cosa che ho notato che ogni volta la sera vedo la uptime DSL (dal modem Poste) di non più di 3 ore, quindi sicuramente si sgancia molto frequentemente.
