1) Do not use WEP.  It's busted. It's *known* busted.  You transmit
packets for more than a minute or so using WEP, you may as well not
bother with crypto at all.  Yes, it's really that busted.

2) You're much better off spending the $15 to get a wireless card
that actually has hardware WPA2 support on it.  The devices are
cheap, there's no reason to inflict pain on yourself.

I'd not be at all surprised if a card that doesn't have crypto
support isn't *also* lacking other hardware support for WPA/WPA2
So while it may well be *possible* to do it in software, I'd have
to rank it as one of the more masochistic ideas I've heard in a
long time.
