***This is a how-to on compiling the latest Broadcom driver for people who's card is not working/supported by the driver in repositories***

Hi guys

I just bought a Lenovo Thinkpad E420 some days back. It came pre-installed with Windows 7. So, I chucked that out and installed Ubuntu 11.04 (though I must add I still use in under Gnome classic). But after installation, like most other Linux users, I had a nightmare and the wireless was not working. Right clicking wouldn't be given me an option to 'Enable Wireless'. I tried every single solution on this forum:
http://ubuntuforums.org/showthread.php?t=1604868

but only to get more frustrated. Weird results as of some commands which I would like to share:

So, coming to the point I thought I should start a thread for people who are struggling with Broadcom drivers for wireless.

To tell you the truth, I only followed the instructions on the Broadcom drivers website which is at

http://www.broadcom.com/support/802.11/linux_sta.php

But I would like to give step by step instructions for people who might have had difficulty following the readme file

1.

Code:

sudo apt-get install build-essentials linux-headers-generic

Code:

sudo apt-get build-dep linux

These 2 steps are required to install the relevant headers and tools
Step 2 might return an error regarding sources.list. Don't worry about it!

3.

Code:

sudo uname -r

Note down the kernel version number. I will be required at a later stage to load the driver at boot up

4. Download relevant driver - 32bit or 64bit

5. Make a directory in the home folder using

Code:

mkdir hybrid_wl

6. Change directory using

Code:

cd hybrid_wl

7. Untar the file to the directory we just created

Code:

tar xzf <path>/hybrid-portsrc_x86-32_v5.100.82.38.tar.gz

In my case <path> was home/kamal/Downloads
So I wrote

Code:

tar xzf home/kamal/Downloads/hy...

8. Now build the driver as linux loadable kernel moduleh

Code:

make clean
make

After the build a wl.ko file will be created in this directory

Now, if you have installed STA or any other Broadcom driver before remove it from Synaptics by searching for 'b43'
For removing STA, use

Code:

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

Then type

Code:

lsmod | grep "b43\|ssb\|wl"

If any of the following are installed, remove them:
# rmmod b43
# rmmod ssb
# rmmod wl

Though, as per my understanding, the purge command should remove each and every bit.

9. Then type

Code:

sudo modprobe lib80211

If it returns any error, use

Code:

sudo modprobe ieee80211_crypt_tkip

And then

Code:

insmod wl.ko

Your wireless should be working now and you can enable it by clicking the nm-applet

**Load Driver at boot time**

Now like a smart-*** I didn't do it at first.

Type

Code:

sudo cp wl.ko /lib/modules/'uname -r'/kernel/drivers/net/wireless

And then

Code:

sudo depmod -a

Now the last command, which was meant to be used in Ubuntu, as per the readme, didn't work for me. I had some syntax error.

You can try it by typing

Code:

sh: for i in `find /lib /var -name wl\.ko`; do mv $i ${i}.orig; done

What I tried was meant to be for Fedora but worked on my Ubuntu.

Code:

sudo echo modeprobe wl >> /etc/rc.local

Now, this one denied me permission when I tried to do it this way. So, I had to log in as root and do the command and it worked. Strange, eh!
Later I realised you can use the root terminal as well to do it. It can be found the applications once you unhide it.
