b43-phy0 ERROR: Firmware file "b43/ucode15.fw" not found -> Wireless Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01) not working on Dell Inspiron 1440 in Ubuntu 12.04 LTS

Asked by Rafael Estrada-Carsolio

I can not make Ubuntu (12.04) reckon my wlan. I Use a Dell Inspiron 14, with a Dell 1397 WLAN minicard. I use my notebook on a dual mode Windows Vista (32), Ubuntu 12.04. Obviously I am using Vista to post this.

Normally I do not do anything on Vista to have the WLAN going. What should I do in Ubuntu, since the only message I get is: "device not ready" or something like that.

Hi,

Please first connect your wired network adapter to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1:

If you are using the Gnome interface, open the Terminal console via "Applications->Accessories->Terminal"

If you are using the Unity interface, the easiest way to open the Terminal is to use the 'search' function on the dash. Or you can click on the 'More Apps' button, click on the 'See more results' by the installed section, and find it in that list of applications. A third way, available after you click on the 'More Apps' button, is to go to the search bar, and see that the far right end of it says 'All Applications'. You then click on that, and you'll see the full list. Then you can go to Accessories > Terminal after that.

So the methods in Unity are:
Dash > Search for Terminal
Dash > More Apps > 'See More Results' > Terminal
Dash > More Apps > Accessories > Terminal

Step 2: Please copy-paste the following command from https://help.ubuntu.com/community/WirelessTroubleshootingProcedure in Firefox into the Linux Terminal. Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command. The command STARTS with the word sudo and ENDS with the word lsmod. So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

sudo apt-get update; sudo apt-get install hwinfo grep rfkill; sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | egrep 'acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|ireless|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|ound|p54|prism|rtl|rt2|rt3|rt5|rt6|rt7|usb|witch|wl';sudo dmidecode|egrep 'anufact|roduct|erial|elease'; iwconfig; cat /etc/modprobe.d/* | egrep 'acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|wmi|witch|wl'; cat /var/lib/NetworkManager/NetworkManager.state; sudo hwinfo --netcard ; ps -aux|egrep 'wpa|icd|etwork'; sudo lsmod

Step 3: Please post results (copy/paste terminal output) on this thread. The troubleshooters here need to see the full Terminal output from running the above command.

Regards,

Mark Rijckenberg

Hello everyone:

TKS for the support. I experienced some unrelated problems with my wired internet access and could not provide the info earlier.

The result after copy/paste-run the sequences suggested are as follow:

The command I sent you, is a single command and should NOT be cut into pieces.

Please visit the following URL (when responding) using a webbrowser, instead of using your Email client:

https://answers.launchpad.net/ubuntu/+source/broadcom-sta/+question/182225

The main problem is that your BCM4306 802.11b/g Wireless LAN Controller does not have any driver loaded for it. This is because the b43 driver is being blacklisted by a configuration file located in the directory /etc/modprobe.d. The configuration file that is blacklisting the b43 driver is likely /etc/modprobe.d/blacklist.conf

You will first need to run the following commands using a WIRED Internet connection:

sudo apt-get update

sudo apt-get remove --purge bcmwl-kernel-source

Then please run the following command:

gksudo gedit /etc/modprobe.d/blacklist.conf

Using the gedit editor, please REMOVE the following configuration lines in
the /etc/modprobe.d/blacklist.conf file:

blacklist b43
blacklist b43legacy

SAVE the change to the /etc/modprobe.d/blacklist.conf file after removing the configuration lines.

Then please proceed with the following commands:

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

b43-fwcutter exists in the Ubuntu repositories, but you will need a
working wired Internet connection in Ubuntu in order to locate it and
install it.

The only way to do that - in your case - is to connect the pc to the
wireless router using a LAN cable, instead of using wireless.

Then reboot your PC and run the following command:

sudo rfkill unblock all

Then retest wireless.

Please copy-paste the following commands into the Terminal (using a working, WIRED Internet connection):

sudo apt-get update
sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install firmware-b43-lpphy-installer

Then please copy-paste each command below one by one into a Terminal. Hit <ENTER> after each command.

echo "blacklist bcma" | sudo tee -a /etc/modprobe.d/blacklist.conf
echo "blacklist brcmsmac" | sudo tee -a /etc/modprobe.d/blacklist.conf
echo "blacklist brcm80211" | sudo tee -a /etc/modprobe.d/blacklist.conf

After running the commands above, make sure to select "Load Defaults" in the BIOS, save the configuration.

Then reboot and retest wireless.

Also it happened to me that after an upgrade of the system wifi stopped working despite 'firmware-b43-lpphy-installer' installed. In this case it was sufficient to do

sudo dpkg-reconfigure firmware-b43-lpphy-installer

After it completed I didn't even have to turn the wifi off and on. It just loaded need modules and connected automatically.
