The Router's default password is 'admin', and it is strongly recommended that you change the Router's password. If you leave the password filed blank, all users on your network will be able to access the Router simply by entering admin into the password field.  

Old Password:
Enter the old password. The default Password is 'admin' when you first power up the Router.
(Note: The password cannot be recovered if it is lost or forgotten. If the password is lost or forgotten, you have to reset the Router to its factory default settings.)

New Password:
Enter a new password for the Router. Your password must be less than 64 characters long and it can't contain any spaces.

Confirm New Password:
Re-enter the password for confirmation.

Click the Save Settings button to save the Password settings or click the Cancel Changes button to undo the changes.
