Hi, So those status=0x83 means it failed the long retry limit: IWM_TX_STATUS_FAIL_LONG_LIMIT = 0x83 so it's failing to get an ACK. The TX setup is: iwm0: sending data: qid=0 idx=2 len=30 nsegs=1 txflags=0x00003008 rate_n_flags=0x0000420a rateidx=0 So, rate_n_flags = 0x420a, which is: IWM_RATE_1M_PLCP = 10, (0xa) first antenna (0x4000) - (1 << IWM_RATE_MCS_ANT_POS) 0x200 - CCK (IWM_RATE_MCS_CCK_POS) So it's tryignt o send the frame as a 1M CCK frame Ok, for the tx_flags: 0x8 = IWM_TX_CMD_FLG_ACK 0x1000 = IWM_TX_CMD_FLG_BT_DIS 0x2000 = IWM_TX_CMD_FLG_SEQ_CTL So it looks like it's a static, single rate (1MB), no multi-rate retries, and it fails to ACK. Can you do an 'ifconfig -v wlan0 list scan' ? I'd like to see if this AP is (say) refusing to allow 1M CCK frames (eg a "no 11b" policy.) Thanks! -adrian
