Descripció

In /etc/config/wireless, when a 802.11(b)gn device's "hwmode" is set to "auto", it only works as a 802.11g device, reaching a maximum of 54 Mb/s:

config wifi-device 'radio0'
    option type 'mac80211'
    option macaddr '10:fe:ed:32:8a:2a'
    option channel '1'
    option country 'SP'
    option hwmode 'auto'
    option htmode 'HT20'
    option txpower '17'
    option noscan '1'
    option distance '5000'
    list ht_capab 'SHORT-GI-20'
    list ht_capab 'SHORT-GI-40'
    list ht_capab 'RX-STBC1'
    list ht_capab 'DSSS_CCK-40'

In the same device, with plain OpenWrt, the default configuration sets "hwmode" correctly to "11ng" (both in Attitude Adjustment and Barrier Breaker):

config wifi-device 'radio0'
        option type 'mac80211'
        option channel '11'
        option macaddr '10:fe:ed:32:8a:2a'
        option hwmode '11ng'
        option htmode 'HT20'
        list ht_capab 'LDPC'
        list ht_capab 'SHORT-GI-20'
        list ht_capab 'SHORT-GI-40'
        list ht_capab 'TX-STBC'
        list ht_capab 'RX-STBC1'
        list ht_capab 'DSSS_CCK-40'

config wifi-device 'radio0'
        option type 'mac80211'
        option channel '11'
        option hwmode '11ng'
        option path 'platform/ar934x_wmac'
        list ht_capab 'LDPC'
        list ht_capab 'SHORT-GI-20'
        list ht_capab 'SHORT-GI-40'
        list ht_capab 'TX-STBC'
        list ht_capab 'RX-STBC1'
        list ht_capab 'DSSS_CCK-40'
        option htmode 'HT20'

enabling them to work in 802.11n mode.

Wireless configuration scripts should be fixed to set "hwmode" to "11ng" where applicable, to benefit from 802.11n enhancements.
