Where is WEP/WPA/WPA2 status shown?

In my Vista SP1, I can't seem to find where it shows how my current wireless
connection is, well, connected. I expected to see it in the status of the
connection in Details, but it wasn't there. Yes, in the network properties
of the wireless NIC I can see how it's set, but I don't think that's
necessarily how it ultimately connected. For example, if the router is on
WPA2 Mixed, it would accept either a WPA or WPA2 connection, and if for
whatever reason WPA2 couldn't be established, I think it would fall back to
WPA.
