ASUS DSL-N55U continue disconnessioni della linea ADSL

[auggiecol]

Salve,
da circa tre giorni (dopo aver lavorato benissimo per 4 mesi) ho continue disconnessioni (ogni 35/40 minuti) della linea ADSL infostrada:

Modulation : ADSL2+
Annex Mode : Annex A/L
Line State : up
Lan Tx : 89215
Lan Rx : 48647
ADSL Tx : 20940
ADSL Rx : 35977
CRC Down : 0
CRC Up : 54
FEC Down : 0
FEC Up : 207
HEC Down : 268
HEC Up : 0
SNR Up : 9.9
SNR Down : 6.0
Line Attenuation Up : 10.3
Line Attenuation Down : 22.9
Data Rate Up : 997
Data Rate Down : 19109

Il modem ha l'ultimo firmware installato 3.0.0.4.374_4422 driver version 3.16.18.1 (oggi l'ho re-installato due volte successive con hard reset).

Ho fatto un isolation test (come suggerito da Infostrada) che non ha risolto nulla.

Ho provato a ricollegare il vecchio modem Netgear e non ho nessuna disconnessione (tre ore continuative)

Qualcuno ha qualche consiglio da darmi? Io comincio a pensare che sia un problema HW.
Grazie
