What are your hardware specs?

More info would have been nice, but since we started this on IRC I'll continue.
Please post full output of

sudo apt-get update
sudo apt-get install -f
sudo apt-get install xserver-xorg-input-synaptics

I have a bigger problem. When i type the command iwconfig wlan0 isn't recognized as a device.

So, what exactly is your problem and what are you trying to address first? Are you unable to connect to wireless?

Exactly, I should probably start a new thread

Sounds like a good idea. Make sure to give plenty of info. Or you can always try the IRC if you prefer.
Good luck.
