Unable Getting SSI noise value in NEC WL300NC(ath9k)

now. I want get SSI noise value in Radiotap header by wireshark(on ubuntu 10.04 LTS). but I couldn't, so it became useless during the weekend..... Then, there are some questions.

1.how to Get SSI noise value in NEC WL300NC(running with ubuntu 10.04 default ath9k)?

2.The conditions which acquire the value? (Device,DriverModule,Config..?)

I already succeeded getting other radiotap values(this card can set to monitor mode). I trid update driver-module (compat-wireless2.6),but result doesn’t change.
