I've been able to use wireless on this laptop on FreeBSD 9.0. I just
followed the instructions in the handbook and that was it. This time
round, I seem to have done the same thing, but there's probably
something I must be doing wrong.

The reason why ssid is empty in the output of ifconfig above, is because
I've omitted it in /etc/rc.conf.
Here's my /etc/rc.conf:
cat /etc/rc.conf
hostname="box0"
ifconfig_re0="DHCP"
sshd_enable="YES"
moused_enable="YES"
ntpd_enable="YES"
powerd_enable="YES"
# Set dumpdev to "AUTO" to enable crash dumps, "NO" to disable
dumpdev="AUTO"
wlans_ath0="wlan0"
ifconfig_wlan0="WPA DHCP"
hald_enable="YES"
dbus_enable="YES"
linux_enable="YES"
I didn't put anything related to the Atheros drivers in the
/boot/loader.conf as support for them is compiled into the kernel and
loaded at boot time:
kldstat -v|egrep 'wlan|ath_'
98 pci/ath_pci
434 wlan
433 wlan_wep
432 wlan_tkip
431 wlan_ccmp
430 wlan_amrr
436 wlan_sta 435 wlan_ratectl_none
Quick question...
The ath_hal(4) man page says that the support for my wireless card is
handled via ath_hal. It seems to be compiled into the kernel, but I'm
not seeing it being loaded like the wpa_ and ath_pci modules are.
dmesg|grep -i Ath
ath0: <Atheros 5424/2424> mem 0xd6000000-0xd600ffff irq 16 at device 0.0
on pci2
ath0: AR2425 mac 14.2 RF5424 phy 7.0
egrep 'ath_|wlan_' GENERIC
device wlan_wep # 802.11 WEP support
device wlan_ccmp # 802.11 CCMP support
device wlan_tkip # 802.11 TKIP support
device wlan_amrr # AMRR transmit rate control algorithm
device ath_pci # Atheros pci/cardbus glue
device ath_hal # pci/cardbus chip support
device ath_rate_sample # SampleRate tx rate control for ath
Also, here's my /etc/wpa_supplicant.conf just in case I overlooked
something:
cat /etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
eapol_version=2
ap_scan=1
fast_reauth=1
network={
ssid="plan9"
psk=wpa_passphrase-generated psk
}
Thanks.
