I dont want to have to use a password to login or download or change programs.

I'm assuming that you don't want a login screen at all, but just want to be logged in automatically. If that is not the case, please post again. If that is the case, then go to System > Administration > Login Screen. If the settings are faded out, click Unlock and enter your password. Then click the radio button "Log in as .... automatically" and click Close.

You should be aware that making it so that you don't have to type in your password to perform administrative tasks will make it easier for you to accidentally break your system, and will enable anyone with a minimal degree of technical skill who has physical access to your keyboard for even a few seconds to break your system or to gain control of it (i.e. implant a Trojan which grants them future access).

With that said, to make it so that you don't have to type in your password to perform administrative tasks, open a Terminal window (Applications > Accessories > Terminal). To run a command in the Terminal, you paste it in (or type it in exactly) and then press enter. Run these commands:

sudo -i
cp /etc/sudoers /etc/sudoers.old
VISUAL=gedit visudo

When you run the first command, you may be asked for your password. While entering it, you won't see any placeholder characters (like *). That's OK--just type it in and press enter.

The second command creates a backup of the configuration file you're about to edit.

When you run the third command, a text editor window will come up. In the file being edited, these two lines of text appear somewhere (probably at the very end):

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

Change the second of those lines so that it instead says:

%admin ALL=(ALL) NOPASSWD: ALL

Then save the file and quit the text editor. Finally, run this command:

exit

The above steps will actually make it so that all users (including you) who have administrative privileges can perform administrative tasks without entering their passwords (but they still have to be logged in as themselves, of course). If this is not what you want--i.e., if you want yourself not to have to enter passwords to perform administrative tasks, but you want any other users you create and give administrative privileges to still have to enter their own passwords to perform administrative tasks--then please post again.

If you perform the above steps and they don't work, then select all the text in the Terminal window (Edit > Select All), copy it to the clipboard (Edit > Copy), and post again, pasting all that text here.

Your problem getting wireless to work is a completely separate issue, so you should post a separate question about that.
