b43-fwcutter package

b43-fwcutter fails to fix BCM4318 with switch

Asked by Ralph

The terminal command "gcc fwcutter.c" generates the following output:
/tmp/cnn5aGMs.o In function 'find-file' :
fwcutter.c:(text+0x173c): undefined reference to 'MD5Init'
.......................................................................................... 'MD5Update'
.......................................................................................... 'MD5Final'
collect2: error ld returned 1 exit status

Have solved this issue by editing "fwcutter.c" to read #include "md5.c" rather than #include "md5.h"
An executable b43-fwcutter wasn't found after extraction of b43-fwcutter_019.orig.tar.bz2. The
Laptop contains a Broadcom BCM4318 which works well in Windows XP provided the Wi-Fi switch is
lit so that BCM4318's firmware is up to date. The Wi-Fi switch doesn't light when booted to Ubuntu 15.10.
The compiled a.out file executes without issue or effect; I don't know if hplip.3.15.11.run was located for
the firmware update info/driver. The BIOS of this Acer Ferrari 4006 laptop doesn't know about
the Wi-Fi switch.
Help enabling Wi-Fi with Ubuntu is needed.- Thanks

The following procedure applies to all supported releases of Ubuntu that are NOT End of Life (EOL) in the following table:

https://wiki.ubuntu.com/Releases

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!

sudo apt-get update; sudo apt-get install usbutils pciutils hwinfo grep rfkill; sudo lshw -C network; rfkill list; sudo iwlist scan | grep -Ei 'chan|ssid'; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nnk | grep -iA2 net; lsusb; nmcli nm status; sudo lshw -short; uname -a; sudo updatedb; dmesg | grep -E '02:00|80211|acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|ireless|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|ound|p54|prism|rror|rtl|RTL|rt2|RT2|rt3|RT3|rt5|RT5|rt6|RT6|rt7|RT7|usb|witch|wl';sudo dmidecode|grep -E 'anufact|roduct|erial|elease'; iwconfig; grep -E '80211|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' /etc/modprobe.d/*; cat /var/lib/NetworkManager/NetworkManager.state; sudo hwinfo --netcard ; ps -aux|grep -E 'wpa|icd|etwork'; netstat -rn ; cat /etc/resolv.conf; ls -lia /boot; grep tmpfs /etc/fstab; ubuntu-support-status; sudo update-pciids; sudo update-usbids; sudo lsmod

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/+source/b43-fwcutter/+question/284511

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

Step 4

Please also specify the exact model and make of your PC (if known)

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

Step 5

Please also clarify if you installed Ubuntu to the harddisk and are running from a harddisk install OR if you are only testing Ubuntu in a Live CD session.

Manfred Hampl (m-hampl) said : 		#2

1. Why do you want to compile b43-fwcutter? There are ready-compiled versions available in the Ubuntu sources.

2. The additional parameters needed for the compile and link steps are described in the Makefile for execution with the make command.

3. If you have problems with a WLAN device, please follow Mark Rijckenberg's instructions.

Run the following commands in a Terminal using a working, WIRED ethernet connection to your wireless router:

sudo apt-get update

sudo apt-get install firmware-b43-installer

Then reboot your PC and retest wireless.

Remark: The recommended way to install software on Ubuntu systems is to use pre-compiled packages from the Ubuntu repositories (using programs like software-center, synaptic and apt-get). Only if such pre-built package is not available, you have to download the program source (usually packed as tar or gz file) and compile the programs yourself.
The commands given by mark was all that you need to download the firmware for Broadcom BCM43xx devices, including the required logic to extract the firmware file.
