Broadcom wireless won't turn on

[noveny]

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?

Start again:

You can download this and extract the folder b43
https://dl.dropbox.com/u/10573557/b43_firmware/b43.zip

inspect the dir. /lib/firmware
If you have a folder already 'b43'
We need to rename it
Open a terminal in /lib/firmware and do

su
mv b43 old-b43

Then open a terminal where you have the folder I gave you and do

su
mv b43 /lib/firmware

I am not sure how to open a terminal in /lib/firmware? I know how to open a terminal, but not in a certain location. I did open the terminal and this is what I get:
eelkins@ubuntu:~$ su mv b43 old-b43
Unknown id: mv
eelkins@ubuntu:~$

I can find the b43 folder through the file system/lib/firmware/b43, but when I right click to rename it, the rename option is greyed out--not an option.

You just do

cd /lib/firmware

Alright. Mission accomplished. I renamed the old b43 and downloaded the new one from drop box and now have the new b43 in the lib/directory. I did a restart and still have no wireless. What do I do now?

Thanks,

Ed

now have the new b43 in the lib/directory.

Please confirm it's in /lib/firmware

Then try

sudo modprobe -rv b43

sudo modprobe -v b43
