OK, first... you're going to need:
1. Your Installation CD
2. A machine with a working internet connection (which you obviously have now)
3. Something to transfer a file to your Ubuntu machine, from the machine that has Internet access (thumb drive, burn another CD, we'll assume a thumb drive).
Make sure Ubuntu is booted and you're logged in.
Insert the installation CD
On the left (where all the program icons are), you should see the "CD" pop up.
Right click the CD and choose Open
You should get a window showing various folders that are on the CD (boot, casper, dists, pool, etc..)
Navigate to /pool/main/b/b43-fwcutter
Inside the b43-fwcutter folder, is a file called b43-fwcutter_xxx.deb Double click that .deb file and Ubuntu Software center should open up.. Just click install, and let it install.
On the machine with a working Internet connection, download this file
Also create a text file (I'm assuming the machine with a working connection is a windows machine, so .txt will work fine)
Copy and paste these 2 lines into the txt file:
tar xfvj broadcom-wl-18.104.22.168.tar.bz2
sudo b43-fwcutter -w /lib/firmware broadcom-wl-22.214.171.124/driver/wl_apsta_mimo.o
Save the text file
Now move the .tar.bz2 file and the .txt file to the Ubuntu Machine
First, put the .tar.bz2 file, INSIDE YOUR HOME DIRECTORY. Don't put it in the Downloads folder, or Documents folder... just drop it in your home directory.
Open up a terminal
Open up that .txt file.
Copy/paste the first line into the terminal and hit enter. When it finishes, copy/paste the 2nd line into the terminal, and hit enter. You'll be prompted to enter your username password. Type your password and hit enter (note, you won't see any *** or --- so just type your password and hit enter)
Let that finish.
When it's done, click the "Dash Home" button, and do a search for "Additional Drivers".. and Open the Additional Drivers utility.
You should see an option there that says "b43". Highlight it and click Activate (you'll probably get a message you need to restart)
Restart your machine.
When you log in, give it a second, then you should be able to click the Networking applet, and you should your wireless network. Simply enter your credentials and connect.
