my macbook pro has a password and i can't remember the password so i can't download any program. help please

Insert the boot disk that came with the macbook. Instead of following setup, click the menu at the top and look for 'change password'
easy.

Go to system preferences then to accounts under "My Account" box you will see the login items panel click on this (you will need your password for this) then on the right hand side at the top you will see automatic login click on you account name then go up to disabled and this will turn off the automatic login. Then you can choose as to whether you want a list of users or your name and password. I normally choose list of names as it means you do not need to remember your login name, Hope this helps.

Give it back. Stealing is illegal in this country.

Or ask the person you got it from what the password is.

New it wouldn't have a password.

This is a confusing report. If you are successfully connecting two other computers to the router using the original router password, why can't you connect your MacBook Pro to the router using the same password? Or is it that the other two computers "know" the original password but you don't?
If one of the other two computers is a Mac, use the Keychain Access utility to look up the stored password for the router.
If not, use one of the other two computers to access the router's configuration screens directly and obtain the password that way.
