Re: wpa_supplicant not found AP without SSID in beacon packet

I seem to be seeing the same thing with my ath 5212. As long as the SSID
is announced, it works like a champ, but my home system does not do so
and the wpa_supplicant does not work with it on V8.

My config file:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
ap_scan=1
network={
	ssid="babcom"
	scan_ssid=1
	key_mgmt=NONE
	wep_key0=01234567890...
	wep_tx_keyidx=0
}

Yes, I know I REALLY, REALLY, REALLY need to switch over to WPA. As soon
as I get some time.

I added ap_scan since the V8.0 upgrade, but it is otherwise the
configuration that worked on V7.2.

When the supplicant runs, I see the key and key index set on the
interface, fur the SSID remains blank. If I issue the command 'ifconfig
wlan0 ssid babcom', the card associates almost immediately.
