dats what i get my wlan0 missssing…plz help

So if you can not get the standard stuff to work, or have never got your wireless to work you might consider downloading the driver from Broadcom and compiling it yourself. Here is a link from Broadcom:

Broadcom.com - 802.11 Linux STA driver

Download either the 32 or 64 bit driver, the patch file and the README.txt file to your /home/username/Downloads folder. I have a bash script you can use to compile the file here:

#!/bin/bash

#: Title       : /home/username/bin/install_wireless
#: Date Created: Sat Jun 4 08:55:09 CDT 2011
#: Last Edit   : Sun Jun 5 14:09:09 CDT 2011
#: Author      : J. McDaniel
#: Version     : 1.01
#: Description : 
#: Options     : 

if  $UID -ne 0 ]]; then
  cd ~/Downloads
  rm -rf hybrid_wl
  mkdir hybrid_wl
  cd hybrid_wl
  tar xzf ~/Downloads/hybrid-portsrc_x86_64-v5_100_82_38.tar.gz
  make clean
  patch -p0 < ~/Downloads/5_100_82_38.patch
  make
  echo "Root User Permissions are required, Please Enter the ..."
  echo
  sudo $0 $HOME
  exit 0
fi

cd $1/Downloads/hybrid_wl

/sbin/modprobe lib80211
/sbin/insmod wl.ko
cp wl.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless
/sbin/depmod -a

cat /etc/rc.local | grep "modeprobe wl"
Exit_Code=$?

if  $(( Exit_Code )) -ge 1 ] ; then
  echo modeprobe wl >> /etc/rc.local
fi

exit 0
# End Of Script

Copy the text in the code field into a text editor and save the file into your ~/bin folder (/home/username/bin) as the file install_wireless. Next, open up a terminal session and run the terminal command:


chmod +x ~/bin/install_wireless

To use the script file run the terminal command:

install_wireless

Again, download first either the 64 bit driver: http://www.broadcom.com/docs/linux_sta/hybrid-portsrc_x86_64-v5_100_82_38.tar.gz

OR

The 32 bit driver from here: http://www.broadcom.com/docs/linux_sta/hybrid-portsrc_x86_32-v5_100_82_38.tar.gz

AND The Patch File From Here: http://www.broadcom.com/docs/linux_sta/5_100_82_38.patch

All files must exist in the ~/Downloads folder before you run the install_wireless batch file.

Before anyone can compile a source file, I suggest you visit YaST and installed a few files to allow the compile to work:

Normally to compile a source file you should consider doing the following:

Open YaST / Software / Software Management - Select the View Button on the top left and pick Patterns. Now, you will see several Patterns listed and you want to select:


   Development   

[X] Base Development 
[X] C/C++ Development

Then Press the Accept button on the bottom right and allow these applications to install.

Thank You,
