When I issue the following command:

wicontrol -i ath0 -l

I get this output:

ap[0]:
	netname (SSID):			[ XXXX ]
	BSSID:				[ xx:xx:xx:xx:xx:xx ]
	Channel:			[ 6 ]
	Quality/Signal/Noise [signal]:	[ 0 / 0 / 0 ]
	                        [dBm]:	[ 0 / -149 / -149 ]
	BSS Beacon Interval [msec]:	[ 100 ]
	Capinfo:			[ ESS ]
	DataRate [Mbps]:		[ 11 ]


There is no information listed for signal quality, noise, etc.  Does
anyone know why this is happening?  I am using an Atheros based D-Link
DWL-G520 card, which is otherwise working great on M0n0wall 1.2b7.

Thanks,
Thomas
