We’re using a pair of ConnectCore 6UL in a product and wish to control the WIFI power level.
$ iwconfig wlan0 txpower
and
$ iw wlan0 set txpower limit
Both complete successfully, but appear to have no effect.
$ iw wlan0 set txpower fixed
fails with “Operation not supported (-95)”
I’m not sure if the commands that ‘succeed’ are just being ignored, if the driver doesn’t support power level setting, or what layer things are going wrong here.
How can I set (reduce) the WIFI tx power with the ConnectCore 6UL ?
