I am still having a little trouble and want to thank all of you for your patience and assistance: You guys are GREAT!

I installed the B43 on my desktop, but then had some trouble with the commands. I got an error after the first one, but then thought maybe the others would work. Here are the results:
eelkins@ubuntu:~$ sudo mkdir /lib/firmware/b43
[sudo] password for eelkins:
mkdir: cannot create directory `/lib/firmware/b43': File exists
eelkins@ubuntu:~$ sudo cp Desktop/b43/* /lib/firmware/b43
eelkins@ubuntu:~$ sudo rmmod -f b43
ERROR: Removing 'b43': No such file or directory
eelkins@ubuntu:~$ sudo rmmod -f ssb
ERROR: Removing 'ssb': No such file or directory
eelkins@ubuntu:~$ sudo modprobe b43
eelkins@ubuntu:~$

Any ideas?
