[ubuntu] Broadcom Wireless Setup for Hardy (Step by step)

[alex_kent_18]

I used the following steps to enable my Broadcom Wireless BCM4312 (rev 02).

Step 1 (run in terminal)

echo 'blacklist bcm43xx' | sudo tee -a /etc/modprobe.d/blacklist
sudo apt-get install ndiswrapper-utils-1.9
mkdir ~/bcm43xx; cd ~/bcm43xx

For Step 2, You can check your Broadcom wireless version with this command in terminal : "lspci | grep Broadcom\ Corporation",if your wireless device is different from BCM4312 (rev 02), please refer to the following link for this step and you can continue again with step 3 onwards:

Step 2 (run in terminal)

sudo apt-get install cabextract
wget ftp://ftp.compaq.com/pub/softpaq/sp3...00/sp34152.exe
cabextract sp34152.exe

Step 3 (run in terminal)

sudo ndiswrapper -i bcmwl5.inf
ndiswrapper -l
sudo depmod -a
sudo modprobe ndiswrapper
sudo cp /etc/network/interfaces /etc/network/interfaces.orig
echo -e 'auto lo\niface lo inet loopback\n' | sudo tee /etc/network/interfaces
sudo ndiswrapper -m
echo 'ndiswrapper' | sudo tee -a /etc/modules
echo 'ENABLED=0' | sudo tee -a /etc/default/wpasupplicant

Step 4 (run in terminal)

sudo aptitude remove b43-fwcutter

Step 5 (run in terminal)

sudo gedit /etc/init.d/wirelessfix.sh

Step 6

Paste the followings in the opened file(wirelessfix.sh)and make sure you save it before continuing Step 7

#!/bin/bash
modprobe -r b44
modprobe -r b43
modprobe -r b43legacy
modprobe -r ssb
modprobe -r ndiswrapper
modprobe ndiswrapper
modprobe b44

Step 7 (run in terminal)

Run this :

cd /etc/init.d/ && sudo chmod 755 wirelessfix.sh

Step 8 (run in terminal)

finally run this:

sudo update-rc.d wirelessfix.sh defaults

Step 9

Restart your machine and enjoy the freedom from those wires....

THANK YOU THANK YOU THANK YOU. Several sleepless nights solved here. Wireless works fine on my WMP54GS card now (4306 v3) thanks to you. Well done.

That worked for my broadcom 4306 rev 03. Thanks a ton. asside: What the hell kind of an upgrade breaks both my wireless and ipod support?

[mlaird]

Which driver did you guys use for the 4306 rev 03? I see a download for the 4306 and the 4306 rev 02 on the linked page, but not the rev 03. Do either of you have and AMD 64 machine? And is your wireless interface wlan0, eth1, something else?

I used Step 2b from the link provided.

Me too, but with no luck. Ubuntu AMD 64 or 32?

Please post the exact steps and output from the steps you tried. Without this its going to be hard for someone to help you.

Actually, it seems to be working now. Not sure why it wasn't before. I've rebooted, tried switching between no security and WPA and it seems to work consistently.

One thing I can't get to work that worked really well in 7.10 is a static IP. Anyone have any luck setting a static IP?

Edit: Static IP does work.

Great post, thanks My previous ndiswrapper driver was locking up my computer but this one seems to work fine.

Thanks for this, I got it all to work after trying many other methods. I wasn't able to see wireless until I issued this command:

sudo iwconfig wlan0
