Capsman load balancing group

Hi, I tried to set the load balancing group Capsman. Use 2 access points (wap and Map Lite). My problem is the next:

  • When I have a computer connected Wap and another in the Map Lite does not allow me to connect a third computer to any of the access points.
    In the logs shows the following: mac @ interface rejected, not allowed due to load balancing.
    Why does this happen?
