Er.. What is your problem actually? Wireless not working on 12.04? – harisibrahimkv May 4 '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 4 '12 at 18:28

Which wireless card are you using?

Reply with the output from the following command: lspci

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 – Davi Sá May 4 '12 at 18:33
