Not able to connect to a Network

Hi,

I wanted to use your module on my RasperryPi because i wanted to use the monitor mode which i can't use with the 8192cu module.
So far so good, with your module i'm able to go into monitor mode, but not to connect to a network in managed mode. 
Everytime I do a dchlient wlan0 it goes to timeout. Even with manual IP i'm not able to access my network.

Any ideas ?

Thanks.
