I installed ubuntu 12.04 on my machine, but I can't get wireless connection to work. My computer is Acer Aspire 5610z. I found that some other people that have same computer, face the same problem.

Here is some information about it:

  • It is safe to run it was written by me and some good friends it will help diagnose your wireless issue. Paste this command in a terminal wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script It will download a script and create a file named (wireless-info.txt, or wireless-info.txt.tar.gz) in your home folder paste the contents of the file here pastebin.com then paste the link back here. No internet then go to this link for running the script without internet. [url]ubuntuforums.org/showpost.php?p=12350385[/url]

You have the appropriate driver for your card, b43, blacklisted. Normally, this is a consequence of having the proprietary driver, wl, installed. So, my suggestion is to remove first thing the proprietary driver,

 sudo apt-get purge bcmwl-kernel-source

and then to install the necessary firmware, 

sudo apt-get install firmware-b43-installer

and eventually to load your open source module:

sudo rmmod b43
sudo modprobe b43
