Nstream Dual WEP

Is there a detailed tutorial on setting up WEP over a Nstream Dual connection between 2 RB600’s? I tried using the following link, but have some questions:

http://www.mikrotik.com/testdocs/ros/2.9/interface/wireless.php

Would I need to set the 2 wireless cards in each RB600 to use the newly created security profile?
I was thinking I could apply the profile to the nstream interface, but quickly found out that is not possible. :slight_smile:
