Well, matching frequencies and essids is critical (or should be), but
the cards do have a tendency to autoselect frequencies and essid to
find other cards. If you explicitly give to cards different essids
they should not communicate - that's the whole point of essid. Are
you sure they really have a different essid, or has one of them
changed essid behind your back? Note that iwconfig will give
misleading results for essid (and other things) if the interface is
down.
