802.11n ht connects then disconnects

Tue Apr 3 20:10:37 PDT 2012

I must be misunderstanding something here.

I'm using auth_algs=1 and wpa=0, just for testing but my hostapd starts a RADIUS accounting session then disconnects.  I don't get it.

I get:
AP-STA-CONNECTED
MLME-ASSOCIATE.indication
MLME-DELETEKEYS.request
RADIUS: starting accounting session
nl80211: Event message available
nl80211: Ignored unknown event (cmd=19)
mgmt::deauth
deauthentication: STA=00:0b:6b:b1:20:14 reason_code=3
AP-STA-DISCONNECTED

Why does it need the RADIUS server if everything is open?  Reason code 3 means that the client disconnected?  Why?  Hmmmm...

Is there something wrong with my driver?  It seems like it's compiled okay.  All the ht stuff is compiled in.

Is there something wrong with my hostapd.conf?  I'm confused %^)

thanxs ;^)
