My guess is that your AP is using WPA1. Is this correct?
On my DLINK DAP-2310 with the last firmware, the WPA mode is WPA2 Only. I
cannot check with other AP today.
Are you really sure about that?
Yes, I have double-checked, this is what is shown in the Web GUI.
"Authentication PassPhrase Settings" : "WPA-Personal"
"WPA Mode" : "WPA2 Only"
"Cipher Type" : "TKIP"
WPA1 has been disabled by default because it is not secure.
Make sure your AP is using WPA2 (sometimes called "AES" by vendors).
Only if you cannot change the AP, try: ifconfig iwn0 wpaprotos wpa1,wpa2
$ sudo ifconfig iwn0 wpaprotos wpa1,wpa2
$ sh /etc/netstart iwn0
DHCPREQUEST on iwn0 to 255.255.255.255
DHCPREQUEST on iwn0 to 255.255.255.255
DHCPACK from 192.168.0.51 (ec:a8:6b:ff:15:4e)
bound to 192.168.0.9 -- renewal in 900 seconds.
But not working with
$ sudo ifconfig iwn0 wpaprotos wpa2
$ sudo sh /etc/netstart iwn0
iwn0: no link ........... sleeping
This implies that the AP is using WPA1, no?
Yes it seems so.
Please also show the output of 'ifconfig iwn0 scan' and show any
additional messages produced in /var/log/messages after running
'ifconfig iwn0 debug'.
$ sudo ifconfig iwn0 scan
iwn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
lladdr 60:67:20:43:86:aa

status: no network
ieee80211: nwid my_ssid wpakey [...] wpaprotos wpa2 wpaakms psk
wpaciphers ccmp wpagroupcipher ccmp
And there were no lines here showing access points?
These lines would probably tell us which WPA version is used by your AP,
if you had shown them.
Yes sorry, there is just mine listed:
nwid my_ssid chan 1 bssid 54:b8:0a:39:df:48 -20dBm 54M
privacy,short_preamble,short_slottime,wpa2
$ sudo ifconfig iwn0 debug
$ tail -f /var/log/messages
Aug 19 14:48:29 lt4-alexis /bsd: iwn0: end passive scan
Aug 19 14:48:29 lt4-alexis /bsd: - 54:b8:0a:39:df:48 1! +233 54M ess
privacy rsn! "my_ssid"
This shows the AP is not being selected because it has the wrong channel
(channel 1 when we expected something else, probably cause the scan was
currently scanning 11a mode which only supports channels >= 36, nothing
to worry about) and the wrong encryption settings (rsn!) (so again, this
indicates AP is using WPA1).
