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 Hewlett-Packard HP Pavilion dv4 Notebook (PC/30F7, BIOS F.51 08/17/2009) in Ubuntu 15.10

Asked by Pablo on 2015-10-30

I just installed Ubuntu (15.04) on HP-Pavilion-dv4-Notebook-PC alongside Windows 10. Enable Network is checked but no Wifi networks appear. The machine indicator shows Wifi as on. Wifi works on Windows 10. Reviews previous Launchpad consults on this question, I see entries of 3 or more years ago but I don't know how to apply them to my situation. Ehternet works fine. I will very much appreciate help in how to solve this. Thank you in advance

Did you use the wired connection to get fully updated? You may want to upgrade to Wily, Vivid only has a couple of months support left.

Pablo (ceascolombia) said : #2

When I go to Network Settings, Wifi (Inalambrica--in Spanish) does not appear as an option. Only Wired and Network Proxy.

Pablo (ceascolombia) said : #3

I will upgrade to Wily and report the outcome.

Pablo (ceascolombia) said : #4

I have upgraded to 15.10, but the problem persists, same as described above. No Wifi. What next?
Thank you again for helping me solve this.

Pablo (ceascolombia) said : #5

What is the implication of Wifi or wireless connection not appearing in Network Settings?

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable) and apply all updates.

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

Step 1

In the Ubuntu Terminal console , make sure that unlimited scrolling is enabled:

    click on Edit > Profiles > "Default" profile > Scrolling. Choose "Unlimited" as scrolling option. Click Close and Close again.

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

If you are using the Unity interface (default graphical user interface in Ubuntu), 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:

Press CTRL-ALT-T key combination.

Dash > Search for Terminal

Dash > More Apps > 'See More Results' > Terminal

Dash > More Apps > Accessories > Terminal

Step 2

Please copy-paste the following diagnostic command from the

    https://help.ubuntu.com/community/WirelessTroubleshootingProcedure

website using a web browser (like Google Chromium or Mozilla Firefox) into the Linux Terminal. The command STARTS with the word sudo and ENDS with the word lsmod. So please copy-paste the ENTIRE diagnostic command below from the web browser 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 diagnostic 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!

Step 3

Please do NOT attempt to send any attachment(s). Please copy/paste the full terminal output at this location:

https://answers.launchpad.net/ubuntu/+question/273424

The troubleshooters at Launchpad need to see the full Terminal output from running the above diagnostic command.

Step 4

Please also specify the name of the wireless access point that you are trying to connect to (not the model/make of your router).

NOTE--I do not understand what information I am asked to provide in Step 4..What is meant by the name of the wireless access point

Thank you for your quick response

The solution to your wireless issue is given in your Terminal output:

[ 13.966861] b43-phy0 ERROR: Firmware file "b43/ucode15.fw" not found
[ 13.966866] b43-phy0 ERROR: Firmware file "b43-open/ucode15.fw" not found
[ 13.966870] b43-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all instructions on this website.

Please run these Terminal commands using a working, WIRED Internet connection (using an ethernet cable):

sudo apt-get update

sudo apt-get install firmware-b43-installer

Then run this Terminal command:

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

Using the gedit editor, scroll down and add the following configuration line inside the blacklist.conf file:

blacklist bcma

Your wireless adapter (Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)) should use the b43 driver instead of the bcma driver.

Then reboot your PC and retest wireless.

The name of your wireless access point is the name of your access point in the dropdown list of available wifi points in your vicinity while using the wireless connections GUI ....
