[...] of the first hits in Google was from Dimitar while this blog post has nice detailed instructions. It seems to miss points that make Linux so [...]

@ dimitar, (jan 22 2010)
I have tried uninstalling & reinstalling using the driver manager & it turns the WiFi on till next reboot.
I am trying the rest of what he suggests….

And it works..
I skipped the download from broadcom, because mine already had the driver somehow.
I can tell you what I did that told me this. Go to administration> Hardware drivers. It showed that i had the drivers, but they where not showing up as ‘in use’. I found the wl.ko file by running sudo find / -name wl.ko and copying that to the path he suggested & I edited the RC.local as he suggested, for now I think that should fix me. SO yes, he is right & Thank you sir for this guide!

@ dejuren,

I am not sure how uninstalling and installing exactly the same package will do anything…

If anyone tries this, please post a reply to confirm.

To fix the problem connect the machine to Internet with cable, open the terminal (applications>accessories>terminal) and run the following commands:

$ sudo apt-get –purge remove b43-fwcutter
$ sudo reboot

The machine will reboot here. After it’s back on again execute the next two commands in terminal:

$ sudo apt-get install b43-fwcutter # IMPORTANT: Confirm firmware download when asked
$ sudo reboot

Reboots may not be necessary, but do them just to be on the safe side. After the second reboot you should be able to connect to the wireless network.

Works great!

For any noobs out there who have trouble, preface EVERY command with “sudo”, because it enables root permissions (Administrator permissions, in Windows talk)

Also, if an echo command doesn’t work, use “sudo gedit (filename)” and it will open it up in a text editor for you, so you can then “echo” the line you want.

Works perfectly! Without a doubt, the easiest thing I’ve come across to follow when it comes to installing my wireless driver!
