Description

After insert the madwifi module as followings

    insmod /lib/madwifi/wlan.o
    insmod /lib/madwifi/wlan_xauth.o
    insmod /lib/madwifi/wlan_scan_sta.o
    insmod /lib/madwifi/wlan_wep.o
    insmod /lib/madwifi/wlan_tkip.o
    insmod /lib/madwifi/wlan_ccmp.o
    insmod /lib/madwifi/wlan_acl.o
    insmod /lib/madwifi/ath_hal.o
    insmod /lib/madwifi/ath_rate_sample.o
    insmod /lib/madwifi/ath_pci.o

Why the default tw power is 9dBm, and the maximum value is 16 dBm. Is anything I can do to set the maximun value as the default value and change the limitation(16dBm)?

~ # iwlist ath0 tx
ath0      8 available transmit-powers :
          0 dBm         (1 mW)
          4 dBm         (2 mW)
          6 dBm         (3 mW)
          8 dBm         (6 mW)
          10 dBm        (10 mW)
          12 dBm        (15 mW)
          14 dBm        (25 mW)
          16 dBm        (39 mW)
          Current Tx-Power=9 dBm        (7 mW)

The same situation is in madwifi-0.9.2 and madwifi-0.9.4, thanks.
