Actually, I think I was only half-right. It's normal for iwconfig to
show Encryption key:off when connected to WPA and WPA2 networks, it's
true that WPA and WPA2 are different animals, and I believe it's true
that iwconfig only knows about WEP.

But there's something strange about the "Encryption key:" line. A
survey of my apartment from my laptop, which I connected to via ssh,
revealed that "iwconfig" reports "Encryption key:off", while "iwlist"
shows "Encryption key:on" for the BSSID I'm connected to (And I'm
showing "IEEE 802.11i/WPA2 Version 1" for my encryption mode).

I don't know the cause of the discrepancy, though I could guess at a
half-dozen different plausible sources.
