Benoit, I'll just tell you instead here. I'll paste the relevant data.
From ath5k.h:
---
/* Register for RSSI threshold has a mask of 0xff, so 255 seems to
* be the max value. */
#define AR5K_TUNE_RSSI_THRES 129
/* This must be set when setting the RSSI threshold otherwise it can
* prevent a reset. If AR5K_RSSI_THR is read after writing to it
* the BMISS_THRES will be seen as 0, seems harware doesn't keep
* track of it. Max value depends on harware. For AR5210 this is just 7.
* For AR5211+ this seems to be up to 255. */
#define AR5K_TUNE_BMISS_THRES 7
---
From reg.h:
---
/*
* RSSI threshold register
*/
#define AR5K_RSSI_THR 0x8018 /* Register Address */
#define AR5K_RSSI_THR_M 0x000000ff /* Mask for
RSSI threshold [5211+] */
#define AR5K_RSSI_THR_BMISS_5210 0x00000700 /* Mask for
Beacon Missed threshold [5210] */
#define AR5K_RSSI_THR_BMISS_5210_S 8
#define AR5K_RSSI_THR_BMISS_5211 0x0000ff00 /* Mask for
Beacon Missed threshold [5211+] */
#define AR5K_RSSI_THR_BMISS_5211_S 8
#define AR5K_RSSI_THR_BMISS (ah->ah_version == AR5K_AR5210 ? \
AR5K_RSSI_THR_BMISS_5210 :
AR5K_RSSI_THR_BMISS_5211)
#define AR5K_RSSI_THR_BMISS_S 8
---
So for example try setting AR5K_TUNE_RSSI_THRES to 0. Let me know how this goes.
Luis
