--- Comment #15 from Cy Schubert <cy@FreeBSD.org> ---
Can you perform this test, please.

1. Create an open unprotected network (guest network or otherwise) on an AP.

2. ifconfig wlan1 create wlandev rtwn0 up

3. ifconfig wlan1 ssid YOUR_NEWLY_CREATED_SSID

4. ifconfig wlan1


I just performed this with,

ugen0.9: <Realtek 802.11n NIC> at usbus0
rtwn0 on uhub7
rtwn0: <802.11n NIC > on usbus0
rtwn0: MAC/BB RTL8192EU, RF 6052 2T2R

It fails to associate:

slippy# ifconfig wlan1
wlan1: flags=8c43<UP,BROADCAST,RUNNING,OACTIVE,SIMPLEX,MULTICAST> metric 0 mtu

        ether 6c:5a:b0:4a:cb:f0

Can you please perform the the test above to confirm. Thanks.
