New Netgear ASDL Modem

Found a slightly used Netgear ASDL modem on craigslist.  Picked it up at a reasonable price.  Now I have to get it to recognize my user id and password.  The Qwest tech wrote the password but either I can't read his writing or he made a mistake.  Rather than call Qwest I'm going to try John the Ripper to crack the password. It has been running on two different machines for a couple.  I'll report back if it ever returns a password.
