Titolo: Il modem si disconnette spesso

Possiedo un PC AMD Athlon 900Mhz, 128 Mb di ram con una scheda madre
ignota il sistema operativo e' Win Me.
Dopo che un temporale,circa due settimane fa'ha bruciato il precedente
modem Trust usb, che si connetteva regolarmente a 52k e non ha mai
dato problemi, ho acquistato il  modem D-Link DU-560M usb.
Il sistema operativo lo riconosce come Conexant HCF 56K Data Fax Voice
USB Modem.
Ora ho i seguenti problemi:
- La connessione avviene a 49333, non e' molta differenza ma e'
possibile migliorare?
- Il modem si disconnette da solo molto spesso, generalmente la prima
disconnessione avviene dopo 5 min. circa, le seguenti sono un po' piu'
dilazionate nel tempo e questo e' molto fastidioso e costoso in
termini di "scatto alla risposta". Escluderei un problema di porta usb
perche' il modem e' collegato ad un hub insieme ad una stampante che
non da alcun problema, comunque anche connettendolo direttamente alle
due prese usb del PC il problema si ripresenta.
Il PC e' anche stato riformattato per escludere un eventuale conflitto
con il precedente modem Trust ma il problema non e' stato risolto.
All' accensione si accendono le spie MR e PWR, a connessione avvenuta
si accendono anche OH, DATA e
CR lampeggia durante la ricezione di dati.
Ho aggiunto S10=200 alle impostazioni inutilmente
Mi collego con Libero per l'accesso alla rete
Ho scaricato dal sito 
dlink.it
  anche il driver DU-560M_winme.zip ma
con questo, facendo partire la connessione o semplicemente componendo
un numero con hyperterminal, il modem si spegne (MR e PWR off).
Confido nella vostra collaborazione per risolvere il problema

stacca tutti i telefoni e vedi se migliora,se si si sono bruciati anche i
telefoni


Non ci sono altri telefoni, l'unico viene scollegato quando attacco il

Ho provato a sostituire il driver con lo standard V90 di win me ma il
problema persiste, idem cambiando il cavo telefonico
Grazie
