The : card has an Atheros chip with a 27dBm output power rating. I am using it as : hostap. FreeBSD detects it fine, but the trouble is FreeBSD does not takes : the power level up. The max i was able to set is was 16dBm. (ifconfig ath0 : txpower xx). I tried it on linux with madwifi but same results, so i started : having a few doubts with this card, a friend of mine suggested that i should : try the router OS (www.mikrotik.com) i did, and it worked perfectly. : : can any one tell me why can't i change the power level ? (i did changed : country codes, to no avail) i read some where it is the problem with the : driver ? so is there any patch ? Did you measure the output power directly? Many cards have a final stage amplifier that kicks things up a few dB... Maybe router OS knows about this card's quirks and copes... Warner
