ndis driver presents the valid WiFi network as having the name 0x000000

[Yuri]

Underlying card is Broadcom BCM94312MCGSG (mini-card for laptop) with 
Windows driver.
This same card and driver work fine with pretty much any other network I 
tried.
But this one particular network shows as 0x000000 and I can't connect to it.
Another FreeBSD desktop with native ath driver and apple both connect to 
it fine.

What might be causing such weird behavior?
Is this a known problem?
Any way to troubleshoot this?
