Since I didn't get any replies to my previous post, I'll try to ask a
few more directed questions:
1. Does wpa_supplicant support configuring a connection with static WEP
passwords (what I would call the typical configuration you see on a
Windows machine using WiFi with some kind of protection)?
2. If yes, is this supported with an Atheros-based (madwifi) card?
3. Could someone provide an example of a network block for such a
configuration? What I am trying to use, without success, is:
More details in my previous post, included below. Thanks everyone.
