Here's one short example.
For more, please ask in scripting newsgroups or
microsoft.public.platformsdk.networking.

This is because there are two structures for SSID name:
the old one (NDIS_WLAN_BSSID) has fixed size, it
is what WMI uses on WinXP.
The new struct, NDIS_WLAN_BSSID_EX, has variable size
(so you can't simply make array of these) and it breaks
the older WMI classes.
All modern wi-fi drivers return only new structs.
