I have a user with AR9285 who was able to associate with and use an open network
(WHU-STU in the list below).

When using wpa_supplicant 2.9 they are able to associate and dhclient is able to
obtain an IP address:

However using wpa_supplicant 2.10 they associate 50% of the time but 100% of the
time are unable to communicate with the AP:

Wpa_supplicant 2.10 configures the device with:
authmode WPA privacy MIXED deftxkey UNDEF
While with wpa_supplicant 2.9 the following are correctly set:
authmode OPEN privacy OFF
It appears that wpa_supplicant has configured WPA even though the following are in wpa_supplicant.conf.
network={
ssid="WHU-STU"
key_mgmt=NONE
}
The same drivers are in use.
What am I missing? Or is there something else going on?
