Did you install the netbook edition of Ubuntu!
What is the realtek driver number?

Have you enabled wireless in the drop down menu?

Please don't shout, I'm trying to help you!
The netbook edition would likely have the driver.
But try this. In terminal copy and paste the following

sudo apt-get install lshw

(enter the password you set up

Then copy and paste this in terminal

sudo lshw -short

Is the wireless card detected?

Ok, did you or have you updated? We have to through this. Your wireless card has not been detected. I would install the netbook version...because the driver in 10.10 desktop was not known. (your netbook). 10.10 std does not pick up all drivers
Are you prepared to reinstall now? (the netbook version)

awai91, it's not my answer, merely a suggestion. As you already stated 'im really2 new in ubuntu' so it is very difficult to explain in easy terms.Please do some further research before you take on this mammoth task.
I have time but it is limited.
Please rethink what you want and whether ubuntu will install the driver for the wlan (for your machine). In most cases, it does.
An alternative is http://sourceforge.net/projects/ndiswrapper/ to enable the card.

If you are not conversant with linux then you really need to research. Each machine will have a prob, so there is no easy answer

awai91,

in the terminal run: ifconfig
If you have the wireless driver installed, you should see eth0 for the LAN and eth1 for WLAN, otherwise only 1 of them will likly show.

lspci will show all pci devices including your wireless device. Then you may figure what driver you need (broadcom, ralink, etc)

ALSO: Did you try the simple GUI method?? Menu> System > Administration > Hardware/Additional Drivers
Do a restart so that any hardware might be detected in the post.

If you find that there is not linux driver you can resort to this option: https://help.ubuntu.com/community/WifiDocs/Driver/Ndiswrapper
