General questions about hostapd

[Jeremy Tourville]

I have setup my router to have a wireless AP using Madwifi and Hostapd.  
I followed the instructions listed here:http://leaf.sourceforge.net/doc/bucu-ap.html 

Problem #1I notice that I am only connecting at the "b" rate with my laptop.  I have a "g" card for both my AP and my laptop.If I setup my AP with no encryption though, I can connect at "g" speed. 

Problem #2I'm not quite sure how to change to using AES for encryption.  Right now I am using TKIP.  
I thought in hostapd.conf you would list only ccmp.   
wpa_pairwise=CCMP
vs
wpa_pairwise=TKIP CCMP (my current config)

If I do the first example I am unable to connect at all. 


Here is my configuration-

libssl 0.9.7l Rev 1 uClibc 0.9.28

I'm seeing a lot of this in my daemon logs-

Any insight you may have is greatly appreciated.  Thanks in advance for your help!
