madwifi wrong max txpower

Reported by: anonymous Owned by: nbd
Priority: high Milestone: Backfire 10.03.1
Component: kernel Version:
Keywords: madwifi, txpower, wrong Cc:

Description

instead of 25dbm the maximum txpower is restricted to 20dBm on a mikrotik r52h.

root@BOX:~# iwlist ath0 txpower
ath0      8 available transmit-powers :
	  0 dBm  	(1 mW)
	  8 dBm  	(6 mW)
	  10 dBm  	(10 mW)
	  12 dBm  	(15 mW)
	  14 dBm  	(25 mW)
	  16 dBm  	(39 mW)
	  18 dBm  	(63 mW)
	  20 dBm  	(100 mW)
          Current Tx-Power=20 dBm  	(100 mW)

this is my wireless config:

root@ReaderBOX:~# cat /etc/config/wireless 

config 'wifi-device' 'wifi0'
	option 'type' 'atheros'
	option 'channel' '1'
	option 'diversity' '0'
	option 'rxantenna' '1'
	option 'txantenna' '1'
	option 'country' '392'
	option 'disabled' '0'
	option 'hwmode' '11bg'
	option 'regdomain' '0'
	option 'txpower' '25'

config 'wifi-iface'
	option 'device' 'wifi0'
	option 'encryption' 'none'
	option 'ssid' 'xxx'
	option 'network' 'wan'
	option 'mode' 'sta'

Wouldn't it be nice to allow the maximum regulatory txpower? The patch in the related article is a bit "ugly" i think ...

... same one Meshcube / Fonera under 10.3 ... No way to "push" it :(
