ubuntu 11.10 not able to access Internet

My only way to get to the Internet with my computer is by using my wireless connection. It connects fine with Windows 7, but ubuntu doesn't seem to find the connection. It is Dell INSPIRON 1545.
I tried following the directions given be the web page, but I kept getting the response that it couldn't be installedon my machine,because it required an i386. I allways thought my laptop was an i386.

Here is some information on my system I gathered for your trouble shooters previosly. It was gathered using the root account.

To run a command as administrator (user "root"), use "sudo <command>".
