Hello

I try to use  a WLM200NX atheros card (AR9220) with mimo support.
I use wpa_supplicant v1.0 and hostapd v1.0 from debian 7.0 system.

On hostapd if I use the following options
ieee80211n=1
ht_capab=[HT40-][SHORT-GI-20][SHORT-GI-40]
or
ieee80211n=1
ht_capab=[HT40+][SHORT-GI-20][SHORT-GI-40]
hostap will not start and there is no stdout message nor syslog message
If I use ieee80211n=0 it will start...

On the wpa_supplicant side if I use
        disable_ht=0
        disable_ht40=0
        ht_mcs=""
the syslog has the following error messages

Failed to read or parse configuration '/etc/wpa_supplicant.conf.WPA-PSK'.
Line 559: unknown network field 'disable_ht'.
Line 560: unknown network field 'disable_ht40'.
Line 561: unknown network field 'ht_mcs'.
Line 578: failed to parse network block.
Failed to read or parse configuration '/etc/wpa_supplicant.conf.WPA-PSK'.

Is ht mode not implemented in v1.0?
I want to use full mimo support with this card and
hostapd/wpa_supplicant ...

What I'm doing wrong?

Greetings and thanks

Beat
