how do i get ubuntu to connect to the internet without me having enter my password
 

i share the computer that i have just installed ubuntu on and when i start it up it goes into the desktop without asking for a password but when it tries to connect to the Internet it requests a password how do i make it connect without me having to provide the password the only thing i want a password for is software package installation

we are also wondering why it doesn't show us a fancy splash screen on shutdown and startup like it did when we used the live cd

That is your ISP demanding the password, not Ubuntu. I'm guessing, (you didn't state the type of internet connection), the connection is dial up. If you had a DSL or cable connection, you store the password in the router. Dial up the password is in the logon window. The only thing I can suggest is look for a way to store the password.

Don't know on the splash screens.

If it is true that you are using dial-up, you might want to try telling us what you use to make the connection (wvdial, diald, kppp, kinternet...) as there may be a way to get that to do this for you automagically.
