Wireless Broadcom bcm4306 rev 3 with Hardy

With laptop wired to router, install Hardy Beta (using Alternate CD is faster than the Live Cd version) and reboot into new stsyem
While still connected directly to router run updates using Update Manager
Edit blacklist and save back and exit editor
gksu gedit /etc/modprobe.d/blacklist

# replaced by b43 and ssb.
# blacklist bcm43xx
blacklist b43
blacklist ssb

Reboot
In Synaptic - Search bcm43xx - bcm43xx-fwcutter is listed - tick box and Mark for installation
Click Apply and in the Summary Apply again
Dialog ; Debconf on laptop-hardy - Configuring bcm45xx-fwcutter - checkbox Fetch and extract firmware? - tick the box and click Forward
Applying Changes - Installing software - click Close when done
Exit Synaptic
Network Settings - Unlock and enter pw - Select Wireless connection > Properties and set up
Not working yet - sudo iwconfig shows nothing set up for wlan0
sudo iwconfig wlan0 essid mystery channel 11 (noticed the frequency was wrong - set channel to the one you're using)
sudo iwconfig now shows wlan0 set up
unplug ethernet cable to router - now to check wireless
ping 192.168.0.1 (or whatever your router uses) > no connection
Trying bumping the connection by re-entering Network password in Network Settings
YES - Wireless now working

So what about next time we start up?
Restarting
Wireless not working
sudo iwconfig wlan0 essid mystery channel 11 gets things nearly there but network unreachable
Bumping the connection by re-entering Network password in Network Settings as before
Wireless now working again.





Getting development updates using Command Line (more reliable - not using Update app)
sudo apt-get update && sudo apt-get dist-upgrade

Possible Cures for Hardy screen problem

1. In /etc/X11/xorg.conf
Section "Device"
        Identifier    "Configured Video Device
        Option        "AGPMode" "4"    (added)
EndSection
(This worked for ATI Radion Mobile U1 graphics)

2. Switch to a tty with Ctrl-Alt-F1 and login

Stop GUI
sudo /etc/init.d/gdm stop

Clear X and run setup
sudo dpkg-reconfigure -phigh xserver-xorg

Start
startx

For Quicktime videos in Firefox 3
