4x wi0 compliant cards, with known functional/reliable firmware. The issue is observed with Senao and WMP11 cards.
wi0: Intersil Firmware: Primary 1.01.01, Station 1.05.06
wi1: Intersil Firmware: Primary 1.01.01, Station 1.05.06
wi2: Intersil Firmware: Primary 1.01.01, Station 1.05.06
wi3: Intersil Firmware: Primary 1.01.01, Station 1.05.06
>Description:
wi0 and wi2 are both in client mode. ifconfig gives:
wi0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

Note that the status is 'no carrier'. However wi2 is actually associated; as wicontrol -i wi2 confirms (or a quick ping to the the other side)

>How-To-Repeat:
Unclear exactly what triggers this. It is seen on
a range of machines; with a range of card firmware's
and not always on, say wi2 or wi4. It has been seen
on machines with 3, 4 and 5 wiX cards. And does not
seem to be wi card vendor specific.
>Fix:
Ignore ifconfig and rely on wicontrol
