>Synopsis: ath(4): Cannot use WPA in 802.11a mode
>Category: kernel
>Environment:
System : OpenBSD 6.1
Details : OpenBSD 6.1 (GENERIC) #291: Sat Apr 1 13:49:08 MDT 2017
[email protected]:/usr/src/sys/arch/i386/compile/GENERIC
Architecture: OpenBSD.i386
Machine : i386
>Description:
I am trying to use my OpenBSD machine as a wifi access point with an
ath(4) card. This works fine as long as I either (a) disable WPA or
(b) operate the card in 80211b mode; if I enable WPA in 80211a mode my
clients can no longer connect.
The card is a Wistron DCMA-81. According to the Internet it should come
with an AR5414 chip but dmesg says AR5413 (in case that matters).
>How-To-Repeat:
This is the configuration without WPA that works:
ath0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu
1500
lladdr 00:0b:6b:23:35:a5
index 4 priority 4 llprio 3
groups: wlan
media: IEEE802.11 autoselect mode 11a hostap
status: active
ieee80211: nwid test chan 48 bssid 00:0b:6b:23:35:a5
This is the configuration with WPA in 11b mode that works:
ath0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu
1500
lladdr 00:0b:6b:23:35:a5
index 4 priority 4 llprio 3
groups: wlan
media: IEEE802.11 autoselect mode 11b hostap
status: active
ieee80211: nwid test chan 3 bssid 00:0b:6b:23:35:a5 wpakey

wpa2 wpaakms psk wpaciphers ccmp wpagroupcipher ccmp
And this is the configuration with WPA in 11a mode that does not work:
ath0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu
1500
lladdr 00:0b:6b:23:35:a5
index 4 priority 4 llprio 3
groups: wlan
media: IEEE802.11 autoselect mode 11a hostap
status: active
ieee80211: nwid test chan 48 bssid 00:0b:6b:23:35:a5 wpakey
0x08f0cc3ee0003f37f35e4a79e2c7ed56b38f3d3c1de8692e62a8ccd1ab044fd2 wpaprotos
wpa2 wpaakms psk wpaciphers ccmp wpagroupcipher ccmp
This is what a (Linux) client says when it can't connect:
