link quality in iwconfig with HostAP driver

[Yu, Heeyeol]

Hi all
 
I have question of link quality. In my case I can not see statistics in
hostap driver
eth1      IEEE 802.11-DS  ESSID:"QBSS"  Nickname:"Prism  I"
          Mode:Managed  Frequency:2.422GHz  Access Point:
00:06:25:17:FA:33
          Bit Rate:11Mb/s   Tx-Power=15 dBm   Sensitivity:1/3
          Retry min limit:8   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality:92/92  Signal level:5/153  Noise level:115/153
          Rx invalid nwid:0  Rx invalid crypt:241  Rx invalid frag:0
          Tx excessive retries:118  Invalid misc:41797   Missed beacon:0
 
This is taken from station with iwconfig command near AP running hostAP
driver.
 
But the statistics of AP is
 
 
Warning: Driver for device wlan0 recommend version 13 of Wireless

but has been compiled with version 12, therefore some driver features
may not be available...
 
wlan0     IEEE 802.11-b  Mode:Master  Frequency:2.422GHz
          Access Point: 00:06:25:17:FA:33  Bit Rate:1Mb/s   Tx-Power:-1
dBm
          Sensitivity=1/3
          Retry min limit:8   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality:0/92  Signal level:-69 dBm  Noise level:-90 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:44  Invalid misc:9305   Missed beacon:0
 
Also I personally make and call IOCTL with SIOCGIWSPY or
hostap_get_wireless_stats function, but the value is 
: Quality:14  Signal level:178  Noise level:159
 
What's wrong here?
 
Best regards
