There is no physical switch to enable wireless there.
Notebooks also have function-key combinations to enable and disable the
radio.
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.
There were probably changes between the two, but I have not noticed any
regressions.
Please post the output of 'ifconfig -a'.

I don't see anything obviously wrong. Is an access point within range? Has
someone set it to have a "hidden" SSID?
The reason why ssid is empty in the output of ifconfig above, is because I've
omitted it in /etc/rc.conf.
That's not what I was suggesting. Most access points allow the SSID to
be "hidden". It's not really hidden, this does not greatly increase
security, but it does make the SSID impossible to see on a scan and
requires adding scan_ssid=1 to /etc/wpa_supplicant.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"
DHCP is enabled for both wired and wireless, but only one instance can
be running at once. Comment out the wired section:
#ifconfig_re0="DHCP"
And try again with just the wireless.
If you want both, there is an example using lagg(4) in the Handbook:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-aggregation.html#networking-lagg-wired-and-wireless
But first, get just the wireless working by itself.
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.
'kldstat' should show it.
