[Madwifi-users] Help regarding Transmit Power configuration

[Ramana R. V. K. <rko...@cs...>]

Hi All,

I was wondering if there are any particular power levels for the Atheros
Card that can be configured using the driver. For example, the function
call ath_hal_setuptxdesc as used in the if_ath.c driver code as below has
an arugment txpower.

  ath_hal_setuptxdesc(ah, ds
                , pktlen                /* packet length */
                , hdrlen                /* header length */
                , atype                 /* Atheros packet type */
                , 0x60                  /* txpower XXX */
                , txrate, 1+10          /* series 0 rate/tries */
                , iswep ? sc->sc_ic.ic_wep_txkey : HAL_TXKEYIX_INVALID
                , antenna               /* antenna mode */
                , flags                 /* flags */
                , ctsrate               /* rts/cts rate */
                , ctsduration           /* rts/cts duration */
        );

Now, this txpower currently is hardcoded to 0x60 and I was wondernig if
there are some legal power levels or modes that can be used ?!

Basically, I was trying to figure out a way to increase/decrease the
signal strength using the driver. But it doesnt seem to have any impact ?!
Any ideas/pointers on this particular issue would be great.

Thanks,
Ramana.
