Wireless capability on Dell Latitude 120l used

Asked by Daniel DRAGOMIR on 2011-10-26

I have a Dell Latitude 120L of a friend of mine and I want to make it work on the internet. It cannot see none on the wireless networks in my area. I AM NEW IN UBUNTU. I've installed version 10.04 LTS. I can not understand if it has the wireless device inside of it. I've entered the command lspci and at the end of the listing page it says there is a Broadcom BCM 4318. It is interesting though on the back of laptop there is a label on wich says there might be a Broadcom BRCM 1016 with IC: 4324A-BRCM1016.
I could not get what to do. It appears that it has no fwcutter inside and it cannot be found on the USB that I've used for instalation.
Any suggestion please?

It's a laptop so if you hook it up to a wired internet connection you can not only get updates, you can also use this easily:

There is also a how to for an offline install but the internet will make it easier by far. Surprised you didn't install a later release like Oneiric or Natty

Heloo again actionparsnip,

I've tried first command on Terminal [~$ lspci -vvnn | grep 14e4] and it returned me a different result from what I've been expected: Broadcom Corporation BCM4318 802.11a/b/g/n Wireless LAN Controller [14e4:4318].
I have followed the link you gave me, but, because I'm a newbie in UBUNTU, I am not sure I understand and did the right things. So, I've followed the instructions there for b43-fwcutter, but on that link there is said:

In case you couldn't find the folder, wubi keeps it as a hidden folder so you have to mount it. Follow these steps:

~$ sudo mount -o loop /host/ubuntu/install/.fuse_hidden0000000400000001 /mnt
~$ cd /mnt/pool/main/b/b43-fwcutter/
~$ sudo apt-get install b43-fwcutter
~$ sudo dpkg -i b43-fwcutter*

I do not have a CD to mount from, but instead I have a USB and from this one I've installed UBUNTU. I know there is a wubi file, but, I i've understood well, the command lined in example given before, tells me to mount from CD. HOW can I mount from USB instead? Or, at least, to install from USB?

IT WOULD BE BETTER TO HAVE INSTALLED UBUNTU 11.04?

Thank you so much in advance.

If you're having trouble getting the .deb packages for b43-fwcutter from the installation medium, it might be easier for you to simply go to https://launchpad.net/ubuntu/+source/b43-fwcutter and get them from there. You should get the packages that are specific to your architecture: i386 for 32-bit, or amd64 for 64-bit (this actually has *nothing* to do with whether your computer has an Intel or AMD processor). If a package says _all, then you'll want that too.

There may be other dependencies--other packages you need too. You can find out about the by running this command:

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

That will simulate the installation of the most relevant packages, and let you know what else would have to be installed in order for them to be installed. Often, dkms must be installed. You can get that at https://launchpad.net/ubuntu/+source/dkms.

One you download these .deb files on a machine with an Internet connection, you can put them on a USB flash drive or burn them to a CD and bring them over to your Ubuntu machine.

Can you help with this problem?
