I recently purchased a AIR-LAP1141N-A-K9. I am going to try it out and see how it works. I know it's not a stand alone ap but what firmware would you recommend loading on it to run it as a stand alone? Also if this works well I am interested in buying a controller and more of these. What controllers are compatible with this unit? I see that the manual says 440x are besides that are there any others?
