802.1x troubles...

Ok...I managed to find a series related to this topic on the mail list that indicated the built-in minimal
authenticator wouldn't work for dynamic WEP keying so I disabled that completely and set a fixed WEP key and
things are working. I'm still confused about the keys that are being generated and cycled by hostapd (shown
by iwlist wlan0 key). What are they being used for?

I'll continue now with my freeRADIUS setup and try to get dynamic WEP (and eventually WPA/802.11i) working
with that...

Thanks,

Larry
