Buongiorno! Da qualche giorno le prestazioni della portante VDSL sono precipitate ai livelli di una ADSL.
Prima agganciavo a circa 175/30 (Tiscali FTTS su armadio Fastweb), adesso vado a circa 30/3. L'armadio è vicinissimo, allego le statistiche attuali della linea. Che cosa può essere successo? E' possibile che sia finito su una monorotaia? Grazie in anticipo!
