|Typical login info for most SOHO routers is as follows:|
password: blank (ie: enter nothing here)
Most SOHO routers also come with a "setup guide" which would also tell you the default password.
If the unit has been configured, and the password changed, you would have to reset it back to factory defaults in order to access the management interface.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
