can you also post the output of the following command? route -n – ImaginaryRobots Jul 30 '12 at 20:58
@ImaginaryRobots ok i did – Systeem Faillure Jul 30 '12 at 23:14

The output of iwlist and lsmod you included show that your computer recognised and can use the wireless card, so it's not likely a driver issue.

Based on your routing table, it looks like your computer is set up to send all internet traffic through the ppp0 interface and not the wlan0 interface. try unplugging/disabling any modems or VPNs that you have configured, then try connecting to wireless again.

Your wired properties carrier (whichever it is) is off. You must activate it.

echo on | sudo tee /sys/class/net/eth0/device/power/control
