Have you tired to install the STA driver? By the way I have the same
laptop and two working versions of Natty 11.04 since Alpha testing. I was able to run the STA driver at first but now I use the b43 driver for my versions. Here is my PCI-ID info.

lspci -vnn | grep 14e4
09:00.0 Ethernet controller [0200]: Broadcom Corporation NetXtreme BCM5752 Gigabit Ethernet PCI Express [14e4:1600] (rev 02)
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11a/b/g [14e4:4312] (rev 01)

Please note the PCI-ID is more important than the BCM43xx number.

Here is a link that just might help you

Sorry for the late reply, but my Dell D620 wireless works great after installing these two packages:

b43-fwcutter
firmware-b43-installer

They can be installed from the Software Center or through the command line:

sudo apt-get install b43-fwcutter firmware-b43-installer

A reboot is not necessary - after the install is complete you should have working wifi and the wifi light should light up as well.

The Wifi in my Latitude D620 is not working with 11.10 worked before. I tried the sudo apt-get install b43-fwcutter firmware-b43-installer and still not working. Can any one assist?

I think Additional Hardware installs conflicting drivers. So you must install the correct one and uninstall the one that conflicts.

sudo apt-get install firmware-b43-installer
sudo apt-get remove bcmwl-kernel-source
sudo reboot -n

After reboot if you have not disabled wireless switch (left side slider) and Enable Wireless from network icon, the green wifi icon should light up and start scanning wireless networks.

Thanks to this post

Let's start with basics. Please run and post:

lsmod | grep -e b4 -e wl
lspci -nn | grep 0280
rfkill list all

Thanks.
