[driverloader] TNET1130 txpower problems

[sliverd]

Hi to all.
i have a TNET1130 wireless card i tryed many drivers (linux-wlan-ng; acx100) but
with no good results, so i installed DriverLoader, it seems to work but the
txpower is 0bDm, and when i type:
[root at localhost root]# iwconfig eth1 txpower auto
Error for wireless request "Set Tx Power" (8B26) :
    SET failed on device eth1 ; Operation not supported.

but the other commands (rts ,power and so on) works fine.
whot i have to do?
thanks to all.
