This probably has everything to do with something missing in your
wireless setup on that machine, and nothing else.

FWIW, I have a ThinkPad T41 which has a ath wireless *and* a
button to turn on / off the wireless. I have never had to use the button
in FreeBSD (the machine dual boots windows, and in windows I use this
button).

What happens if you press the key to turn the wireless on / off? Do you
get a signal then? If not I suggest you look elesewhere for your
problem.

On my ThinkPad, this is what I had to set up: (Note: I use DHCP and WPA
/ TKIP encryption. If you use static ip and / or other encryption your
setup will look different)
In /boot/loader.conf:
if_ath_load="YES"
wlan_tkip_load="YES"

In /etc/rc.conf:
ifconfig_ath0="WPA DHCP"

and my /etc/wpa_supplicant.conf (sensitive items have been changed, of
course):
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel

network={
        ssid="<SSID HERE>"
        key_mgmt=WPA-PSK
        proto=WPA
        pairwise=TKIP
        group=TKIP
        psk="<password / key HERE>"
}

And thats it.
