    Is my broadcom 4306 wireless card detected? from this settings.


    I am not sure if my wireless card is detected, although it seems like it is from these settings: of ifconfig -a


    Code:

    Also iwconfig

    eth0      no wireless extensions.
    
    sit0      no wireless extensions.

              Encryption key:off
              Power Management:on
    Also how do I get my Access point associated? But can I rest assured my wireless card does not need further configuration? I have wpa encryption and a netgear wireless router. My ethernet wired eth0 is working fine.

    This is your wireless card but you may need firmware for it to work properly. Post the output of
    Code:
    dmesg | grep -i firmware
    Code:
    ifconfig wlan0 up
    Code:
    iwlist wlan0 scan

    Thanks Mike first, what you ask me to try.

    Code:
    dmesg | grep -i firmware

    localhost frank #
    Code:
    ifconfig wlan0 up
    SIOCSIFFLAGS: No such file or directory


    Code:
    iwlist wlan0 scan
    wlan0     Interface doesn't support scanning : Network is down
    I first tried emerging fw-cutter firmware. that seemed to put :

    Code:
    frank # cd /lib/firmware
    localhost firmware # ls
    b43
    localhost firmware #
    I assumed that that had installed the correct firmware. I still show b43 in /lib/firmware. However, the system seems to prefer, or pull, b43legacy.

    Here is what else I have tried:

    Code:
    lspci -vnn | grep 14e4
    01:08.0 Network controller [0280]: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller [14e4:4320] (rev 02)
    
    I have kernel-3.0.6 by the way
    
    Gentoo
    
    Gentoo systems supply a pre-compiled binary for b43-fwcutter. You need to:
    
    Toggle line numbers
    
       1 emerge b43-fwcutter
    
    and then follow the instructions below to download the Broadcom driver. The line that invokes b43-fwcutter will need to be changed to execute the program emerged above.
    
    If you are using the b43legacy driver:
    
    After installing b43-fwcutter, download version 3.130.20.0 of Broadcom's proprietary driver and extract the firmware from it:
    
    Toggle line numbers
    
       1 export FIRMWARE_INSTALL_DIR="/lib/firmware"
       2 wget http://downloads.openwrt.org/sources/wl_apsta-3.130.20.0.o
       3 sudo b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta-3.130.20.0.o
    
    Note that you must adjust the FIRMWARE_INSTALL_DIR path to your distribution. The standard place where firmware is installed to is /lib/firmware. However some distributions put firmware in a different place.
    
    b43legacy
    	
    
    3.130.20.0
    	
    
    295.14
    	
    
    b43-fwcutter-012 
    
    http://gpo.zugaina.org/net-wireless/b43-fwcutter/euscan
    I used fw-cutter version 15, and could not cut the firmware. I still am not sure , though i listed a website how to configure/download fw-cutter-012. Which is what b43legacy requires. I also was not sure if that was a one as in 1 or an L as in l in apsta. I downloaded first to /home/frank/download, than also with wget. So I ended up with one apsta ending in 0.0 and another one ending in apsta 0.0.1. I may have a lot of broken/corrupt files, don/t know. I am not sure if this are the correct steps for my my kernel. 3.0.6.

    Also do I use the sudo command, and I am doing all this from root by the way.

    Here is my most recent try:

    firmware # sudo b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta-3.130.20.0.o
    This file is recognised as:
    filename : wl_apsta.o
    version : 295.14
    MD5 : e08665c5c5b66beb9c3b2dd54aa80cb3

    Extracting b43legacy/ucode4.fw
    Extracting b43legacy/ucode5.fw
    Extracting b43legacy/ucode11.fw
    Extracting b43legacy/pcm4.fw
    Extracting b43legacy/pcm5.fw
    Extracting b43legacy/a0g0bsinitvals2.fw
    Extracting b43legacy/b0g0bsinitvals5.fw
    Extracting b43legacy/a0g0initvals5.fw
    Extracting b43legacy/a0g1bsinitvals5.fw
    Extracting b43legacy/a0g0initvals2.fw
    Extracting b43legacy/a0g1initvals5.fw
    Extracting b43legacy/b0g0bsinitvals2.fw
    Extracting b43legacy/b0g0initvals5.fw
    Extracting b43legacy/b0g0initvals2.fw
    Extracting b43legacy/a0g0bsinitvals5.fw

    I think that solved that. I probably need more config help. I was not making a space between INSTALL_DIR and wl_apsta. Here is my most recent.iwlist wlan0 scan:

    iwlist wlan0 scan

    Solved broadcom bcm 4306 nic on optiplex gx 270 kernel 3.0.6

    After few days of web searches, I finally got my broadcom 4306 wireless card running. I get a few errors with ethernet cable disconnected, but it seems to be running ok after boot.

    I did not follow, the step as recommended in this website, though still recommend reading. The step to emerge firmware, did not seem to help.

    Broadcom 43xx - Gentoo Linux Wiki

    Instead , I followed the steps in this website, and that did work.

    b43 - Linux Wireless

    I was having problems configuring wpa_supplicant, my connection was flaky turning on and off. this Arch wiki, helped a lot for that problem. It auto generated a wpa supplicant conf that wifie up and running. It offered some other steps, that I followed. Some did not work with my particular gentoo system., but in the end. my connection remains connected after an hour.

    here is my working wpa_conf that is working, with my Netgear Router. Generated by following steps in Arch wiki. I thought there might be a conflict with setting GROUP=wheel and GROUP=0 but so far there hasn't.

    Code:
    ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel
    ctrl_interface=/var/run/wpa_supplicant
    ctrl_interface_group=0
    
    
    network={
            ssid="myssiduseyours"
            psk="mypassphraseuseyourgoeshere"
    
    }
    I read so many posts in various distros, it would be hard to thank every one. But special thanks, to every one, here, for your help.
