Is it possible that modern wireless card only supports WPA and not WEP or this is a bug in the driver?

I am about to do a talk on WEP versus WPA for a course in internet
security.  I became acquainted with the protocols through a
60 minutes story.

WEP is not fully secure.  WPA or WPA2 is the improvement.  The
above story notes that American businesses are in arears with
respect to properly upgrading the wireless routers that they
use for financial processing.
