You could try bringing it down and up by

Code:
sudo /sbin/ifconfig wlan0 down
Code:
sudo /sbin/ifconfig wlan0 up
If sudo asks for a password you could also first gain root and then do these commands without sudo in front.

If that does not do anything, could you paste the output of

Code:
/sbin/ifconfig
