[Tfug] Quick embedded linux question

[Matthew T. Eskes]

Doesn't have iwconfig per se. Went with the syntax "wl radio on/off"

Thanks anyway

I recommend reading the man page for iwconfig.  The section on txpower is
below:

txpower
              For cards supporting multiple transmit powers, sets the
transmit
              power in dBm. If W is the power in Watt, the power in dBm is P
=
              30 + 10.log(W).  If the value is postfixed by  mW,  it  will
be
              automatically converted to dBm.
              In  addition,  on and off enable and disable the radio, and
auto
              and fixed enable and disable power control  (if  those
features
              are available).
              Examples :
                   iwconfig eth0 txpower 15
                   iwconfig eth0 txpower 30mW
                   iwconfig eth0 txpower auto
                   iwconfig eth0 txpower off
