Hi,

I'm not sure wether I should raise a ticket to kernel dev team, openwrt dev team or my brain...

I have a MZK-W04NU (Atheros AR9132). With the vendor's firmware, I can have Wifi N (up to 130Mbps) but with the openwrt firmware (actually trunk 17357), I can't have more than Wifi G (54 Mbps) :

I am wrong or does the driver ath9k can't let this chipset working @130M ?

Another question. Is this normal ? :

wlan0     Interface doesn't support scanning : Operation not supported

Thanks for anyone's help !

Is it possible turn N mode ?

This list represents non-HT bitrates, in other words non 802.11n standard speeds.
N-speeds can be enabled by changing HostAPd configuration. N-speeds should be enabled by default, remember that e.g Intel allows higher speeds only for unsecured networks or WPA2/CCMP encrypted networks.

Check your etc/config/wireless file. It needs to have the 11n specific info such as:

config 'wifi-device' 'wifi0'
    option 'type' 'mac80211'
    option 'macaddr' 'xxxxxxxxxxxxxxxx'
    list 'ht_capab' 'HT40-'
    list 'ht_capab' 'SHORT-GI-40'
    list 'ht_capab' 'DSSS_CCK-40'
    option 'country' ''
    option 'maxassoc' ''
    option 'distance' ''
    option 'diversity' ''
    option 'txantenna' ''
    option 'rxantenna' ''
    option 'disabled' '0'
    option 'antenna' ''
    option 'hwmode' '11ng'
    option 'channel' '05'

I'm getting very good 11n speed with my Sparklan WMIA-199N Atheros 3x3 11n card--the fastest wireless connection I have ever tested.

The discussion might have continued from here.
