Hi everybody,
I am a new user of Ubuntu, I installed the latest version 10.04 LTS, everything works great (sound, video, bluetooth, ...) except the wireless, because my wireless connection was not detected.

I use a laptop DELL Vostro 1015
My network card is Dell Wireless 1397 Mini-Card
The manufacturer is Broadcom (BCM4312)

The site http://linux-wless.passys.nl proposed in the literature shows my configuration in red and wrote:
"Currently no native driver exists for this device"

I checked the BIOS, everything is enabled

I suppose that these commands can give you some informations:

cat /etc/lsb-release
lsusb
lspci
lspci -nn | grep -i net
sudo lshw -C network
lsmod
iwconfig
ifconfig
sudo iwlist scan

uname -r -m

cat /etc/network/interfaces

nm-tool

so this is what i got:


bk@bk-laptop:~$ cat /etc/lsb-release


DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=10.04
DISTRIB_CODENAME=lucid
DISTRIB_DESCRIPTION="Ubuntu 10.04 LTS"

Hi,
I am stuck in exactly the same boat as you. I have a HP DV6-1330 laptop with a broadcom wireless adapter and I upgraded from 9.10 to 10.04 TLS thinking that my WiFi would work. But It doesn't. I first tried to install the proprietary drivers - B43 and STA, one by one (uninstalling one before reinstalling the other). But none of them seem to work.

I also tried to download the official broadcom drivers. But they too didnt work!!

I don't know what happened but I'm pretty sure it worked out of the box in 9.10, if you're not feeling really motivated I'm sure it still works out of the box in 9.10.

This is a bit of an obnoxious method but as far as I know it works, this is what I have to do in Arch at least. The b43 driver should work.


sudo iwconfig wlan0 power on
sudo ifconfig wlan0 up
at this point you should be able to scan
sudo iwconfig wlan0 essid *network name* key *network passwd*
dhclient wlan0 (I actually use dhcpcd but I think this is still the right command)

Just replace wlan0 with whatever your wireless interface is and if that doesn't work post back here and we'll figure it out.

Broadcom's README.txt file for its proprietary driver provides installation instructions for both Fedora and Ubuntu. The file has not yet been updated to reflect the relatively recent release of Ubuntu 10.04 Lucid Lynx, but the instructions still worked well for me on a Dell Vostro 1015:


Ubuntu:
------
Go to System->Administration->Hardware Drivers
Choose the Broadcom STA wireless driver
Activate

Sometimes the driver does not show up in the Hardware Drivers choices. In
this case, try reintalling the driver from the GUI or shell like this:

From the GUI:
Package Manager (System>Administration>Synaptic Package Manager). Click the
Reload button in the upper left corner of Synaptic to refresh your index then
search for and reinstall the package named bcmwl-kernel-source.

From the shell:
sudo apt-get update
sudo apt-get --reinstall install bcmwl-kernel-source

In either GUI or text case, after reinstalling, reboot your machine.

Now go back to System->Administration->Hardware Drivers
and you should see the driver enabled and working.The driver (in the form of object code) and supporting documentation are available at Broadcom's website:
