Description

My SoC is kirkwood , 88F6281. like QNAP TS-419P

if enable WPA2 or WPA, inactive time too high. why? E.G.:inactive time: 73670 ms
inactive time to 7xxxx ms, reset to 0 ms, and to 7xxxxms.

WiFi link status looks OK, but can't ping. can't transport data.

iw dev wlan0 station dump
Station 00:15:00:5f:f8:2c (on wlan0)
        inactive time:  73670 ms
        rx bytes:       2092058
        rx packets:     22917
        tx bytes:       93065140
        tx packets:     62389
        tx retries:     723081
        tx failed:      0
        signal:         -43 dBm
        signal avg:     -38 dBm
        tx bitrate:     300.0 MBit/s MCS 15 40Mhz short GI
        rx bitrate:     270.0 MBit/s MCS 15 40Mhz

if disable wpa2 or wpa, That's great'''
inactive time : 0-xxx ms
ping is ok. transport data OK!

iw dev wlan0 station dump
Station 00:15:00:5f:f8:2c (on wlan0)
        inactive time:  130 ms
        rx bytes:       36742597
        rx packets:     408517
        tx bytes:       1828838143
        tx packets:     1217770
        tx retries:     14288105
        tx failed:      0
        signal:         -42 dBm
        signal avg:     -109 dBm
        tx bitrate:     300.0 MBit/s MCS 15 40Mhz short GI
        rx bitrate:     270.0 MBit/s MCS 15 40Mhz

this is my config. disable wpa2 config

 cat /etc/config/wireless 

config 'wifi-device' 'radio0'
        option 'type' 'mac80211'
        option 'macaddr' '00:22:5f:92:d9:f0'
        list 'ht_capab' 'SHORT-GI-40'
        list 'ht_capab' 'TX-STBC'
        list 'ht_capab' 'RX-STBC1'
        list 'ht_capab' 'DSSS_CCK-40'
        option 'channel' '44'
        option 'txpower' '14'
        option 'hwmode' '11na' cat /etc/config/wireless 

cat /etc/config/wireless 

config 'wifi-device' 'radio0'
        option 'type' 'mac80211'

        option 'txpower' '14'
        option 'hwmode' '11na'
        option 'htmode' 'HT40+'
        option 'country' 'US'

config 'wifi-iface'
        option 'device' 'radio0'
        option 'network' 'lan'
        option 'mode' 'ap'
        option 'ssid' 'DDNAS'
        option 'macfilter' 'allow'
        list 'maclist' '00:15:00:5f:f8:2c'
        option 'encryption' 'none'
