  • Er.. What is your problem actually? Wireless not working on 12.04? – harisibrahimkv May 04 '12 at 18:22
  • My wireless does not work in unity with ubuntu, but ubuntu gamers already in the works normal when I'm in the live cd 12.04 message appears in network connections: wireless hardware disabled. and this has already happened in version 11.04, I waited to see if the update would fix this problem and nothing ... – Davi Sá May 04 '12 at 18:28

If it's a broadcom wireless card then you will need to run the following to get wireless working. 

sudo apt-get install firmware-b43-installer

I had a similar problem. In my case, it was working fine, but I had to reinstall Kubuntu (unrelated issue), and it wasn't working anymore. I fixed it like this (requires wired connection):

Go to System >> Additional Drivers.
Remove the Broadcom STA drivers.
Activate Broadcom STA drivers (will download and reinstall).
Problem solved.

Things helped me to enable wireless network:

My laptop: Vista, Compaq, UBUNTU 12.04

  1. lshw returned *-network UNCLAIMED
  2. connected to wired network
  3. ran sudo apt-get update;
  4. Verified broadcom driver in "Additional Drivers". Wirless options are not yet available after this step.
  5. lshw returned *-network DISABLED.
  6. ran sudo modprobe b43; At this point I was able to see the wireless options in the menu, but these options are not enabled. The light on wireless switch is amber.
  7. ran echo b43 | sudo tee -a /etc/modules > /dev/null; still not wireless is not enabled. The light on wireless switch is amber.
  8. ran sudo apt-get install firmware-b43-installer; This turns the wireless light to blue and wireless options are available.

I have read many blogs. Each step here comes from a different blog. But finally worked. Thanks for everyone.

I am still wondering how did the wireless worked automatically when I ran Ubuntu from CD in recovery mode and why can't the install do the same! That would save a lot of time.

Connect to the internet on that computer with ethernet if possible and go to PREFERENCES >> ADDITIONAL DRIVERS

The driver for your wireless card should pop up if you are connected to the internet. Then just click INSTALL or ENABLE.(I forget what verbiage is used there)

  • in version 11.04 I also did this, but I will not install the driver from the broadcom wirelss card, so I'll try to get home and put the answer.

    thank you
