Okay ... Here is the good news .. I figured out how to find it ..

... Now the bad news is this is geeks stuff and you shouldnt try it if you arent confident with CLI.
So to find out your ISP Password, Do this:
Start > Run > Cmd <Press Enter>
On the Command line, type:
telnet 192.168.1.1 <Press Enter>
Type your router username and password. (The default is admin/admin unless you have changed it).
On the telnet cli, type this:
console enable <Press enter>
Console should look like this:
Quantum>
Now in the console mode, type this :
Quantum> fm <Press Enter>
Now type:
Quantum fm>cat im.conf <Press Enter>
Now this will be a big file, and will take around a 20 seconds to list. After the listing is finished, find the string "password". The text listed against weLoginPassword is your ISP password. Its stored in cleartext.
Tell me if you could do it .. I am thinking about posting it to my blog ..
