This question already has an answer here:

I've just installed ubuntu on a laptop that came with Windows 7 pre-installed. In Windows 7 I was able to connect to the same wireless network that the other computers in my house are connected to but I can't do so in Ubuntu.

When I open Network through System Settings I don't have a wireless option, the only two options I have are Wired and Network Proxy.

I'm trying wireless troubleshooting on help.ubuntu and apparently the driver is unclaimed.

How can I fix this?

Maybe you should start with stating the model of your laptop and the wireless card you are using. –  January Sep 24 '12 at 11:05
    
You can use the lspci command from the Terminal (Ctlr+Alt+T) and give us the output of the program (so that we can know the hardware of your laptop). –  Alex Sep 13 '13 at 6:12

At first go to Settings - Additional Drivers and try to install wireless driver.

If it's already installed and you still don't have wireless option try installing Wicd network manager. Install it by Ubuntu Software Center or by terminal

sudo apt-get install wicd-daemon

Then start it. Under Applications-Internet, or by terminal just type wicd.

Check now if you can see and connect to any wireless network.

**In case of problems while installing (just installed it via Ubuntu Software Center, so no problems there).. http://wicd.sourceforge.net/moinmoin/Wicd%20on%20Ubuntu

When I open Additional Drivers it gives me a message saying 'Downloading package indexes failed, please check your network status. Most drivers will not be available.' –  joeqesi Sep 24 '12 at 11:30
    
In terminal type < sudo apt-get update > and then try Additional drivers.. –  Alen T Sep 24 '12 at 11:37

You have to connect temporary by cable to download and configure wireless conection.. –  Alen T Sep 24 '12 at 11:44

Also, I downloaded Wicd network manager but it says that no wireless networks were found. –  joeqesi Sep 24 '12 at 12:18
