I think the WPS might not be the main reason.
If AP was enabled QSS, ifconfig wlan0 list scan would include WPS.
Today I went through a number of tests and found the following:
AP: 802.11bgn mixed / QSS enabled / channel:11 / 20MHz / 130mbps
X201i/FreebSD9/amd64/iwn0 can connect to AP.
802.11bgn mixed / QSS enabled / channel:11 / 40MHz / 300mbps
Or 802.11bgn mixed / QSS enabled / channel:11 / Auto / 300mbps
X201i/FreebSD9/amd64/iwn0 can't connect to AP.
wpa configure:
network=3D{
ssid=3D"OpenBSD"
#+ any_bssid
key_mgmt=3DWPA-PSK
proto=3DRSN
psk=3D"12345678901"
}
Following are detailed scan information
