its definatley possible to do 12-14km links with the internal antennas as
ive done so with them using OpenWRT and no external antennas connected
but i do agree setting external or internal is a bit confusing, i read here
that setting both to 0 uses the external antenna, though nobody specifies
setting what to 0
goipctl set 7 makes gpio 7, gpioctl clear 7 sets it low
i think with the code changes being pushed someone should actually help
people decipher what the proper setting for internal or external antennas
are as ive got a few radios with external high gain antennas, and i still
struggle to validate with signal which antennas is actually the active one,
or if the external antennas are actually being utilized, or not. the signal
strength seems to not be any different which i find quite odd. so i ask is
there a definitive doc for NS2 configuration internal / external
ive read so much out there its hard to differentiate whats correct and whats
not.
right now i belive internal should be
config wifi-device wifi0
option type atheros
option channel 11
option mode 11g
# option distance 200
option antenna auto # (auto|horizontal|vertical|external)
# option disabled 0
config led
option name wlan
option sysfs wlan
option default 1
as external should be
config wifi-device wifi0
option type atheros
option channel 11
option mode 11g
# option distance 200
option antenna external # (auto|horizontal|vertical|external)
# option disabled 0
and
config led
option name wlan
option sysfs wlan
option default 0
now is this correct or am i missing something
