iwn / Intel Centrino Advanced-N 6205 / WPA2-Enterprise

[Joseph Mingrone]

Hello,

I'm running 9.2-STABLE (r264631: Thu Apr 17 23:48:34 ADT 2014) amd64.
The Intel Centrino Advanced-N 6205 wireless card works fine with the iwn
driver on WPA2-Personal networks, but it's a different story with
WPA2-Enterprise [1].

The problem is that the connection drops frequently, even when I'm only
a few metres from the access point.

This is what the entry looks like in /etc/wpa_supplicant.conf.

network={
 	ssid="Dal-WPA2"
	scan_ssid=1
 	key_mgmt=WPA-EAP
  	identity="me"
  	password="my_password"
	eap=PEAP
  	phase1="peaplabel=0"
  	phase2="auth=MSCHAPV2"
}

Pasted at the end, is a sample of what I see in /var/log/messages.  What
else should I be looking at to debug the issue?  Is this a known
problem, perhaps related to some commits to current in the last few
months (e.g.,
http://svnweb.freebsd.org/base?view=revision&revision=258829)?  Is there
any other debugging information I can provide to shed some light?

[1] At least I think the problem is related to WPA2-Enterprise.  I've
only used WPA2-Enterprise with one network, but it's one I connect to
daily and the problem is consistent.
