Hello,
Does anyone know how to enable short preamble in 7-STABLE ?
I'm using ath with hostapd in ap mode. It seems there was an option in =
hostapd.conf, but this is not in FreeBSD's =
/usr/share/examples/hostapd/hostapd.conf
The missing hostapd.conf option was found in google:
# Short Preamble
# This parameter can be used to enable optional use of short preamble =
for
# frames sent at 2 Mbps, 5.5 Mbps, and 11 Mbps to improve network =
performance.
# This applies only to IEEE 802.11b-compatible networks and this should =
only be
# enabled if the local hardware supports use of short preamble. If any =
of the
# associated STAs do not support short preamble, use of short preamble =
will be
# disabled (and enabled when such STAs disassociate) dynamically.
# 0 =3D do not allow use of short preamble (default)
# 1 =3D allow use of short preamble
#preamble=3D1
my version of hostapd is " v0.5.10 " - I was not able to set this option
hostapd.conf:
interface=3Dath0
#preamble=3D1
debug=3D1
ctrl_interface=3D/var/run/hostapd
ctrl_interface_group=3Dwheel
ssid=3Dprivate
wpa=3D1
wpa_passphrase=3Dapassword
wpa_key_mgmt=3DWPA-PSK
wpa_pairwise=3DTKIP
rc.conf:
hostapd_enable=3D"YES"
ifconfig_ath0=3D"mode 11g hidessid mediaopt hostap"
ifconfig ath0:
