The first thing I notice is that you apparently do not have CRDA installed. A 
second thing is that the interface never comes up. As long as it remains down, 
it can never connect. How are you connecting? I'm using NetworkManager.

The following is an excerpt from my dmesg log with debug=3 set when rtlwifi is 
loaded:

As you notice, this connection uses the CCMP algorithm, i.e. it is with 
WPA2-AES.  It is also an 802.11n. Just to test, I switched the AP to run only at 
802.11g rates. That also worked.

I need to know more about your setup. What AP and how is it configured? How do 
you control the wireless connection?
